DC 24DYNAMIC CONTROLLERData Sheet-1General DescriptionThe Rane Model DC 24 Dynamic Controller is a two chan-nel Compressor, Limiter, Expander Gate system with very un-usual attributes. The DC 24 offers unprecedented control of its operating parameters as well as a built-in 24 dB/octave Linkwitz-Riley Crossover which gives it very impressive capabilities.Total freedom from control interaction highlight the DC 24 as well as the availability of separate Compressor and Limiter controls. The Compressor offers control over both Ratio and Threshold, while the Limiter allows setting a separate Threshold. In doing this, the DC 24 allows the operator to create a smooth transition between subtle compression over a wide dynamic range and peak-stop limiting at the sound system’s highest allow-able level. If that’s not enough, the DC 24 also offers indepen-dent Expander/Gate Ratio and Threshold controls. This third level of signal manipulation makes the DC 24 a most useful and revolutionary device.Attack and release times are automatic and program depen-dent. This simplifies use of the DC 24, as these subtle controls can confuse most users. History has proven that experienced compressor users rarely miss these controls after using a DC 24.The internal Crossover allows the DC 24 to operate as a two-way speaker dividing network along with all of the dy-namic characteristics of a fully featured Compressor Limiter. In addition to this application, the DC 24 supplies the necessary circuitry to allow the unit to divide a single channel of audio information in two separate frequency ranges and to then re-combine the program material into one Channel. Using the DC 24 in this way eliminates the pumping and breathing associated with compression and limiting when only one Channel is used to cover the entire audio spectrum.Refer to “The DC 24 User’s Guide,” on the Rane website, for an easy-to-understand guide of operation and applications.Features• Ratio & Threshold Controls for Compressor and Gate/Expander • Limiter Threshold Controls• Program Dependent Attack & Release• Linkwitz-Riley Crossover with 24 dB per Octave Slopes • Low-High Crossover Mode (1 In/2 Out)• Bandsplit Combine Mode (1 In/1 Out)• Stereo/Dual Modes (2 In/2 Out)• Side Chain Insert Jacks• Balanced XLR & ¼" TRS Connectors • -10 dBV / +4 dBu Gain Switch• UL/CSA Remote Power Supply (120 VAC)• CE (Low Voltage & EMC) Remote Power Supply (230 VAC)DATA SHEETDC 24DYNAMIC CONTROLLERData Sheet-2Parameter Specification Limit Units Conditions/CommentsCompressor..........Threshold Range -50 to +205dB ..........Ratio Range 1:1 to 10:110%Expander / Gate..........Threshold Range -50 to +105dB ..........Ratio Range 1:1 to 20:110%Limiter..........Threshold Range -20 to +202dBCrossover ..........Type Linkwitz-Riley 4th-order 24 dB per octave slopes..........Range 70 Hz to 7 kHz5%41-detent continuously variable pot Inputs: Type Active Balanced / Unbalanced ..........Connectors XLR & + ¼" TRS ..........Impedance20k 1%Ω..........Maximum Level +201dBuOutputs: Type Active Balanced ..........Connectors XLR & + ¼" TRS ..........Impedance1001%ΩEach output ..........Maximum Level +261dBu 2 kΩ or greater +201dBu 600 Ω or greaterOverall Gain Range -12 to +12±1dB Center detent unity gainRFI FiltersYes Passive Bypass SwitchYes LED Thresholds: Overload +221dBu Output or any internal level ..........Signal Present -403dBu Input LevelFrequency Response 20 Hz to 20 kHz +0/-.5dB THD+Noise0.05.01%+4 dBu, 1 kHzIM Distortion (SMPTE)0.1.01%60 Hz / 7 kHz, 4:1, +4 dBuSignal-to-Noise Ratio 1082dB Unity Gain re +20 dBu, 20 kHz BW 922dBUnity Gain re +4 dBu, 20 kHz BW Unit: Agency Listing ..........120 VAC model Class 2 Equipment National Electrical Code UL & CSA Exempt Class 2 equipment ..........230 VAC model CE-EMC EMC directive 89/336/EECCE-SafetyExempt per art. 1, LVD 73/23/EEC Power Supply: Agency Listing Rane model RS 1Class 2 Equipment ..........120 VAC model UL File no.

The gating function shall provide a means for setting the gate threshold as well as the ratio of the function thus providing a means for gentler slopes to oc-cur such as one would expect to find in an expander.The compressor shall also provide a means for setting thresh-old and ratio independently. The limiter shall also provide a means for setting its operational threshold, but shall differ from the other two functions in that limit ratio shall be a function of limit level.All attack and release characteristics provided by the dynam-ic controller shall be a function of the current program material, thus providing a high level of transparency to the listener.The dynamic processor shall provide an active crossover circuit for the purpose of using the unit to drive amplifiers con-nected to two-way loudspeaker systems as well as for dividing a single channel audio source into two frequency bands for ulti-mate recombination at the outupts of the device. The crossover shall be a fourth-order Linkwitz-Riley type configuration.Passive bypass switches shall be provided to ensure total bypass of the unit’s active circuitry in the event of power failure. The inputs and outputs shall be active balanced/unbalanced designs terminated with XLR & ¼" TRS connectors. The side-chain send and receive connectors shall be ¼" unbalanced types, wired tip=send, ring=return.RFI filters shall be provided at the processor’s inputs. LEDs shall be provided to indicate the presence of an input signal as well as high level overload conditions.The unit shall be exempt from agency safety requirements and powered from a UL listed / CSA certified remote power sup-ply (120 VAC), or CE approved (230 VAC) via a rear panel input modular plug.The unit shall be entirely constructed from cold-rolled steel, and mount into a standard EIA relay rack occupying 1 rack space.The unit shall be a Rane Corporation Model DC 24.DC 24DYNAMIC CONTROLLERData Sheet-4All features & specifications subject to change without notice.DOC 107501Rear PanelAvailable Accessories • SC 1.7 Security Cover©Rane Corporation 10802 47th Ave. W., Mukilteo WA 98275-5098 TEL 425-355-6000 FAX 425-347-7757 WEB Application InformationTraditionally, a product such as the DC 24 has been referred to as a “Compressor / Limiter” because the range of the Ratio control on the Compressor has been wide enough to accommo-date both gentle compression and harder limiting effects. Not, however, simultaneously. One had to make a choice between the two modes of operation. On some models a Gate has been pro-vided which may or may not be part of the Compressor function.In the DC 24, all three functions of each channel are inde-pendent. Gating may occur when low-level signals are present, compression may occur when the level increases, and “peak-stop” limiting is available for high-level signals. This provides a three slope capability which is rather unique in the audio industry.Additionally, the DC 24 can help out a great deal on the low end of the amplitude spectrum by serving as a noise gate simul-taneously. The Compressor may be used to “tighten” vocals and instrumentals while leaving the Limiter function available for use as a safety valve.To accomplish this feat, the DC 24 provides three separate “Side Chains” in each Channel, each having its own set of front panel controls. For the Gate / Expander function, input signal is converted from an audio format to a control signal and ap-plied to the threshold circuit. If the output of the controller is below the specified threshold, it is passed along to the Gate / Expander Ratio control. The Ratio control allows attenuation of the controller to inhibit the slope of the Expander. After this at-tenuation, the control signal is delivered to the Channel’s control summing amplifier where it will meet similar signals generated by the Compressor control system.The Compressor controller works remarkably similarly to the Gate, the exception being the polarity. While the Gate circuit reduces gain when input level decreases below Threshold, the Compressor decreases gain when input increases above Thresh-old. The Compressor also receives the output of the controller, applies it to its threshold determinator, and passes the signalto the ratio attenuator if threshold conditions are satisfied. The output of the Ratio control is applied to the summing amplifier referenced in the gate section.Side Chain inserts have been provided on the rear of the unit to allow the insertion of an equalizer into the control circuits of the Gate and the Compressor. This will allow the user to create a frequency-dependent threshold for the Gate and/or the Compressor. This feature is useful when attempting to control sibilance in vocals.The Limiter operates in an entirely different manner than the preceding sections. The control circuit for the Limiter monitors the output of the VCA, not the input of the unit. Anytime the output of the VCA exceeds the Threshold set on the front panel, Limiting begins to take place. The ratio of the Limiter is set automatically and is a function of the excess level the system is attempting to deliver above the preset Threshold. The attack and release time of the Limiter is a function of the speed at which the input signal is attempting to drive the output of the unit above the Threshold level.The Crossover function of the DC 24 is based on Rane’s time-proven 4th-order state-variable Linkwitz-Riley design. This yields a 24 dB per octave slope and an in-phase characteristic. Since the outputs are in phase with each other, they recombine properly when the channel summing mode is selected via the rear panel Separate/Combine switch.In its band-split mode, the DC 24 allows separate processing of low frequencies and high frequencies; a mode which makes its operation all the more transparent. When the Crossover is used in conjunction with a two-way loudspeaker system, adequate driver protection may be ensured while providing a very flexible means of program manipulation.For a better view of the various operational modes, refer to “The DC 24 Users Guide” RaneNote, from the Rane website.。

General DescriptionThe MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communica-tions interfaces, particularly applications where ±12V is not available.These parts are especially useful in battery-powered sys-tems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225,MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for appli-cations where printed circuit board space is critical.________________________ApplicationsPortable Computers Low-Power Modems Interface TranslationBattery-Powered RS-232 Systems Multidrop RS-232 Networks____________________________Features Superior to Bipolaro Operate from Single +5V Power Supply (+5V and +12V—MAX231/MAX239)o Low-Power Receive Mode in Shutdown (MAX223/MAX242)o Meet All EIA/TIA-232E and V.28 Specifications o Multiple Drivers and Receiverso 3-State Driver and Receiver Outputs o Open-Line Detection (MAX243)Ordering InformationOrdering Information continued at end of data sheet.*Contact factory for dice specifications.MAX220–MAX249+5V-Powered, Multichannel RS-232Drivers/Receivers________________________________________________________________Maxim Integrated Products 1Selection Table19-4323; Rev 9; 4/00Power No. of NominalSHDN RxPart Supply RS-232No. of Cap.

MAX247/MAX248/MAX249 Control Pin ConfigurationsM A X 220–M A X 249_______________Detailed DescriptionThe MAX220–MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 dri-vers, RS-232 receivers, and receiver and transmitter enable control inputs.Dual Charge-Pump Voltage ConverterThe MAX220–MAX249 have two internal charge-pumps that convert +5V to ±10V (unloaded) for RS-232 driver operation. The first converter uses capacitor C1 to dou-ble the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output.A small amount of power may be drawn from the +10V (V+) and -10V (V-) outputs to power external circuitry (see the Typical Operating Characteristics section),except on the MAX225 and MAX245–MAX247, where these pins are not available. V+ and V- are not regulated,so the output voltage drops with increasing load current.Do not load V+ and V- to a point that violates the mini-mum ±5V EIA/TIA-232E driver output voltage when sourcing current from V+ and V- to external circuitry. When using the shutdown feature in the MAX222,MAX225, MAX230, MAX235, MAX236, MAX240,MAX241, and MAX245–MAX249, avoid using V+ and V-to power external circuitry. When these parts are shut down, V- falls to 0V, and V+ falls to +5V. For applica-tions where a +10V external supply is applied to the V+pin (instead of using the internal charge pump to gen-erate +10V), the C1 capacitor must not be installed and the SHDN pin must be tied to V CC . This is because V+is internally connected to V CC in shutdown mode.RS-232 DriversThe typical driver output voltage swing is ±8V when loaded with a nominal 5k ΩRS-232 receiver and V CC =+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V mini-mum driver output levels under worst-case conditions.These include a minimum 3k Ωload, V CC = +4.5V, and maximum operating temperature. Unloaded driver out-put voltage ranges from (V+ -1.3V) to (V- +0.5V). Input thresholds are both TTL and CMOS compatible.The inputs of unused drivers can be left unconnected since 400k Ωinput pull-up resistors to V CC are built in (except for the MAX220). The pull-up resistors force the outputs of unused drivers low because all drivers invert.The internal input pull-up resistors typically source 12µA,except in shutdown mode where the pull-ups are dis-abled. Driver outputs turn off and enter a high-imped-ance state—where leakage current is typically microamperes (maximum 25µA)—when in shutdownmode, in three-state mode, or when device power is removed. Outputs can be driven to ±15V. The power-supply current typically drops to 8µA in shutdown mode.The MAX220 does not have pull-up resistors to force the ouputs of the unused drivers low. Connect unused inputs to GND or V CC .The MAX239 has a receiver three-state control line, and the MAX223, MAX225, MAX235, MAX236, MAX240,and MAX241 have both a receiver three-state control line and a low-power shutdown control. Table 2 shows the effects of the shutdown control and receiver three-state control on the receiver outputs.The receiver TTL/CMOS outputs are in a high-imped-ance, three-state mode whenever the three-state enable line is high (for the MAX225/MAX235/MAX236/MAX239–MAX241), and are also high-impedance whenever the shutdown control line is high.When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1µA with the driver output pulled to ground. The driver output leakage remains less than 1µA, even if the transmitter output is backdriven between 0V and (V CC + 6V). Below -0.5V, the transmitter is diode clamped to ground with 1k Ωseries impedance. The transmitter is also zener clamped to approximately V CC + 6V, with a series impedance of 1k Ω.The driver output slew rate is limited to less than 30V/µs as required by the EIA/TIA-232E and V.28 specifica-tions. Typical slew rates are 24V/µs unloaded and 10V/µs loaded with 3Ωand 2500pF.RS-232 ReceiversEIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert.Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels.The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors withDrivers/Receivers 14Table 2. Three-State Control of ReceiversMAX220–MAX249Drivers/Receivers______________________________________________________________________________________15nominal 5k Ωvalues. The receivers implement Type 1interpretation of the fault conditions of V.28 and EIA/TIA-232E.The receiver input hysteresis is typically 0.5V with a guaranteed minimum of 0.2V. This produces clear out-put transitions with slow-moving input signals, even with moderate amounts of noise and ringing. The receiver propagation delay is typically 600ns and is independent of input swing direction.Low-Power Receive ModeThe low-power receive-mode feature of the MAX223,MAX242, and MAX245–MAX249 puts the IC into shut-down mode but still allows it to receive information. This is important for applications where systems are periodi-cally awakened to look for activity. Using low-power receive mode, the system can still receive a signal that will activate it on command and prepare it for communi-cation at faster data rates. This operation conserves system power.Negative Threshold—MAX243The MAX243 is pin compatible with the MAX232A, differ-ing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication. Different cables are not needed to interface with different pieces of equipment.The input threshold of the receiver without cable fault protection is -0.8V rather than +1.4V. Its output goes positive only if the input is connected to a control line that is actively driven negative. If not driven, it defaults to the 0 or “OK to send” state. Normally‚ the MAX243’s other receiver (+1.4V threshold) is used for the data line (TD or RD)‚ while the negative threshold receiver is con-nected to the control line (DTR‚ DTS‚ CTS‚ RTS, etc.). Other members of the RS-232 family implement the optional cable fault protection as specified by EIA/TIA-232E specifications. This means a receiver output goes high whenever its input is driven negative‚ left floating‚or shorted to ground. The high output tells the serial communications IC to stop sending data. To avoid this‚the control lines must either be driven or connected with jumpers to an appropriate positive voltage level.Shutdown—MAX222–MAX242On the MAX222‚ MAX235‚ MAX236‚ MAX240‚ and MAX241‚ all receivers are disabled during shutdown.On the MAX223 and MAX242‚ two receivers continue to operate in a reduced power mode when the chip is in shutdown. Under these conditions‚ the propagation delay increases to about 2.5µs for a high-to-low input transition. When in shutdown, the receiver acts as a CMOS inverter with no hysteresis. The MAX223 and MAX242 also have a receiver output enable input (EN for the MAX242 and EN for the MAX223) that allows receiver output control independent of SHDN (SHDN for MAX241). With all other devices‚ SHDN (SH DN for MAX241) also disables the receiver outputs.The MAX225 provides five transmitters and five receivers‚ while the MAX245 provides ten receivers and eight transmitters. Both devices have separate receiver and transmitter-enable controls. The charge pumps turn off and the devices shut down when a logic high is applied to the ENT input. In this state, the supply cur-rent drops to less than 25µA and the receivers continue to operate in a low-power receive mode. Driver outputs enter a high-impedance state (three-state mode). On the MAX225‚ all five receivers are controlled by the ENR input. On the MAX245‚ eight of the receiver out-puts are controlled by the ENR input‚ while the remain-ing two receivers (RA5 and RB5) are always active.RA1–RA4 and RB1–RB4 are put in a three-state mode when ENR is a logic high.Receiver and Transmitter EnableControl InputsThe MAX225 and MAX245–MAX249 feature transmitter and receiver enable controls.The receivers have three modes of operation: full-speed receive (normal active)‚ three-state (disabled)‚ and low-power receive (enabled receivers continue to function at lower data rates). The receiver enable inputs control the full-speed receive and three-state modes. The transmitters have two modes of operation: full-speed transmit (normal active) and three-state (disabled). The transmitter enable inputs also control the shutdown mode. The device enters shutdown mode when all transmitters are disabled. Enabled receivers function in the low-power receive mode when in shutdown.M A X 220–M A X 249Tables 1a–1d define the control states. The MAX244has no control pins and is not included in these tables. The MAX246 has ten receivers and eight drivers with two control pins, each controlling one side of the device. A logic high at the A-side control input (ENA )causes the four A-side receivers and drivers to go into a three-state mode. Similarly, the B-side control input (ENB ) causes the four B-side drivers and receivers to go into a three-state mode. As in the MAX245, one A-side and one B-side receiver (RA5 and RB5) remain active at all times. The entire device is put into shut-down mode when both the A and B sides are disabled (ENA = ENB = +5V).The MAX247 provides nine receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs each control four drivers. The ninth receiver (RB5) is always active.The device enters shutdown mode with a logic high on both ENTA and ENTB .The MAX248 provides eight receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs control four drivers each. This part does not have an always-active receiver. The device enters shutdown mode and trans-mitters go into a three-state mode with a logic high on both ENTA and ENTB .The MAX249 provides ten receivers and six drivers with four control pins. The ENRA and ENRB receiver enable inputs each control five receiver outputs. The ENTA and ENTB transmitter enable inputs control three dri-vers each. There is no always-active receiver. The device enters shutdown mode and transmitters go into a three-state mode with a logic high on both ENTA and ENTB . In shutdown mode, active receivers operate in a low-power receive mode at data rates up to 20kbits/sec.__________Applications InformationFigures 5 through 25 show pin configurations and typi-cal operating circuits. In applications that are sensitive to power-supply noise, V CC should be decoupled to ground with a capacitor of the same value as C1 and C2 connected as close as possible to the device.Drivers/Receivers16______________________________________________________________________________________。
