professional quality tube sounds in a modern, exceptionally compact 19" rack-mountable package (1 rack space). The two main channels Clean and Lead feature dedicated voicing sections, gain pots and volume controls for precision sound shaping and fine-tuning. The Gain Lo/Hi switch converts the Clean channel to a Crunch channel and, in the Lead channel, the sound spectrum encompasses everything from Heavy Crunch to Ultra Gain. With a 4-band voicing section featuring two midrange bandwidths and ahandy feature is the Defeat function, which bypasses the preamp and routes the guitar signal directly to the output. This feature enables you to connect two preamps in series and this option enlarges the tonal spectrum. The variable Stereo Line Out and a frequency compensated Line O ut give you a wide range of application options, for instance you can patch the preamp signal directly to a mixing console or recording devicewhich is equipped with an impressive array of high-tech features that deliver a wide range of devastating sounds, come highly recommended. The integrated 2 x 1, 5 Watt stereo poweramp is suitable for three different applications:1, practicing with stereo headphones,2. practising with hi-fi stereo speakers, and3, practicing with a conventional guitar speaker cabinet.This preamp is defined by the effort and materials that went into it: intelligent design features, superior craftsmanship, impeccable finishing and quality components. However keep in mind, that a few precautions will radically extend tube life (see handling and care guidness).The entire-Team would like to thank you for your faith in ourproduct; we hope you derive a great deal of joy and satisfaction fromPLEASE NOTE: Read the O perator's Manual carefully and thoroughly, especially the Handling and Care section as well as the guidelines in bold-face type. Avoid operating errors and potential damage to the preamp by heeding the guidelines and cautionary remarks in this manual. The footnotes also cover a few convenient pointers and interesting tips on several functions. These are listed on side 3 of the manual.Gain settings depend on what type of pickups are installed in your guitar. The recommended setting for humbuckers or active pickups lies between the 10 and 1 o ’clock positions and 12 to 3 o ’clock for single coils for a pure clean response.For a crisp glassy tone, set the Bright switch to the On position. This setting boosts the treble response of muddy pickups.To get an idea of this preamp's capabilities in the Clean-Mode, we suggest you set thetone control pots Bass (5), Middle (6) and Treble (7) to the 12 o'clock position.To get Crunch or heavy Rhythm sounds, set this control between the 10 and 1 o ´clock ´s position (depending on the type of pick-up) and leave the Gain Boost (15) pusbuttonin the Off-position. All functions that can be accessed via footswitch can also be switched via the ENGL MIDI Switcher Z- 11. Simply connect the two 1/4" stereo jacks (22) and (23) to the stereo inputs of the Switcher via two cables equipped with 1/4" stereo plugs. You can control switching functions via the buttons on the Switcher. The respective functions (e, g. Lead, Hi -Gain,Contour active, Defeat off) are saved to the desired MIDI program locations. The ENGL MIDI Footswitch Z-12 is ideal for activating MIDI programs. When used in conjunction with the ENGL MIDI Switcher Z-11, this durable footswitch does not require a separateAC power pack. The requisite power is routed via the MIDI cable.To get an idea of this preamp's Lead sounds, we suggest you set the tone control pots Bass (9), Lo Mid (10), Hi Mid (11) and Treble (12) to the 12 o'clock position. The Treble control is important when operating the preamp in combination with a poweramp that does not feature a Presence control: Set the Treble pot between the 7 and 12 o ´clocksposition it suppresses the gritty upper frequencies. The integrated miniature stereo poweramp delivers maximum output of 2 x 1. 5 Watts at 4 ohms. However, you can connect diverse systems with impedances of 4, 8 and 16 ohms as well as headphones with 200 ohms. To the achieve the desired audio result, it is essential that the Selector switch (24) located on the rear panel is set to the proper position. The volume level of the poweramp is determined by the volume level settings for the two channels and the setting of the LINE LEVEL control (29). If the LINE LEVEL pot is turned up fairly high, then the setting for the two volume controls (7) and (14) must be reduced substantially so that the poweramp is not saturated!PLEASE ENSURE YOU HEED THE FOLLOWING: If you are using the amp to drive just one speaker cabinet, connect only one stereo channel via a 1/4" stereo plug. A mono 1/4" plug will short-circuit the poweramp's second channel. If you operate the amp under these conditions at high volumes for a longer period of time, this may destroythe amp or other components!The LINE outputs (25) and (26) provide signals that emulate the response of a 412 guitar cabinet, The signal level is nominally identical to the level at the LINE outputs (27) and (28).However in practice, the level deviates slightly due to frequency compensation. When the preamp is active, the output level of the LINE outputs depends on the following factors:the input level (Gain), the Volume control settings for the respective channels, and in some measure, the voicing section control settings. This is why we recommend that you dial in the desired sound via the front panel control features, set a desired FX level (if you have connected a processor) and then use the LINE LEVEL pot (29) to dial in a suitable level.The following is another conceivable practical application: Patch the outputs (27) and (28) to a stereo poweramp (e.g. ENGL 830/50) to drive two cabinets (e.g. ENGL 412G or S)and the two frequency compensated LINE outputs to the PA mixing console. The emulated 412 signal can be used for the FOH sytem so you do not have to mic your guitar cabinets.The filter stages, integrated LINE amp and the headphones amp can also be used for external application, depending on how you route the signals. Use the two FX LOOP RETURN jacks (30) and (31) as signal inputs. The preamp signal is interrupted when a1/4" jack is inserted. (refer to the Signal Routing Plan).BASSBottom end voicing control for theLead Channel.LO MIDLo Mid-range voicing control (at 500 Hz)for the Lead Channel.LEAD GAINGain control for the Lead channel, controls theamount of distortion in the Lead mode.CAUTION: Extremely high gain and volumelevels in the Lead mode can produce strongfeedback. Avoid feedback squeals, they leadto hearing loss and damaged speakers!TREBLEUpper range voicing control for theClean Channel.7CLEAN VOLUMEVolume control for the Clean channel.BASSBottom end voicing control for theClean Channel.MIDDLEMid-range voicing control for theClean Channel.BRIGHTAlters the EQ by boosting the upper treblerange; (above 2 kHz).Front1INPUTUnbalanced 1/4" (main) input jack.CLEAN GAINHI MIDHi Mid-range voicing control (above 1 kHz)for the Lead Channel.TREBLEUpper range voicing control for theLead Channel.CONTOURPress this button to alter the mid-EQ. When thebutton is pressed, mids between 300 & 500 Hzand mids between 1 & 2 kHz are boostedslightly; the red LED indicates Contour active.This function can also be activated via afootswitch connected to jack (23). Once afootpedal is connected, the channel selectorpushbutton is deactivated.LEAD VOLUMEVolume control for the Lead channel.14GAIN LO / HIThis button increases the gain levels for bothchannels. When you activate it, the Cleanchannel responds more like a Crunch channel,and the Lead channel delivers a hi-gain leadsound. You can also activate this function viafootswitch (Jack 22), the Gain Boost pushbuttonis then no longer functional. The LEDilluminates to indicate Hi-Gain mode is active.CLEAN / LEADChannel selector pushbutton for Clean andLead modes, red LED indicate Lead mode;This function can also be activated via afootswitch connected to jack 22. Once a foot-pedal is connected, the channel selector push-button is deactivated.PREAMP DEFEATThis feature bypasses the preamp when thebutton is depressed. In this case the guitarsignal is routed to the Instrument Outputjack (32) .You can also activate this function viafootswitch (at Jack 23), the Preamp Defeatpushbutton is then no longer functional.The LED above the button illuminates toindicate the preamp is bypassed.POWERAC power on/off.19STEREO HEAD PHONES1/4" stereo output designed for stereoheadphones. you can also connecthi-fi speakers or guitar cabinets. When youconnect a conventional guitar cabinet set theselector switch (24) to ,,Routed to GuitarCabinet."CAUTION! Ensure You Heed The Following:Always use a 1/4 stereo plug. If you use amono plug, it may short-circuit and destroythe poweramp!Rear Planel20AC SocketConnect AC cord here.CAUTION: Ensure you use an intact ACcord with an insulated plug only! Beforeyou power the amp up, ensure the voltagevalue printed beside the AC socketcorresponds to the available current.21AC Fuse BoxContains mains fuse (rear chamber) andspare fuse (front chamber).NOTE: Ensure replacement fuses bearidentical ratings (refer to the table)!22FOOTSWITCH:CLEAN/LEAD; GAIN LO/HI1/4" stereo jack for connecting a dualfootswitch (e.g. ENGL Z-11) or a MIDI-switching system (e.g. ENGL Z-11).The following functions can be executed:1.Channel switching Clean - Lead(mono terminal)2.Gain Lo - Hi (stereo terminal).23FOOTSWITCH:PREAMP DEFEAT; CONTOUR1/4" stereo jack for connecting a dualfootswitch (e.g. ENGL Z-11) or a MIDI-switching system (e.g. ENGL Z-11).The following functions can be executed:1.Preamp Defeat / Bypass(mono terminal).2.Contour switching (stereo terminal).24HEADPHONES OUTPUT:A) Routed To Headphones Or HiFi Cab.B) Routed To Guitar Cab.Rear panel selector switch for front panelheadphones jack. Set the switch to the leftposition A) when you connect stereoheadphones or hi-fi speakers and to theright position B) when you connect aguitar cabinet to ensure proper frequencycompensation for the respective systems.FREQUENCY COMPENSATED LINEOUTPUT: RIGHTLine Out for the preamp's right frequencycompensated signal (1/4" unbalanced jack).This signal can be patched directly to amixing console or a recording device.FREQUENCY COMPENSATED LINEOUTPUT: LEFTLine Out for the preamp's left frequencycompensated signal (1/4" unbalanced jack).This signal can be patched directly to amixing console or a recording device.LINE OUTPUT: RIGHTLine Out for the preamp's right channel(1/4" unbalanced jack).This signal can be routed to a powerampor a FX device via a shielded cable.LINE OUTPUT: LEFTLine Out for the preamp's left channel(1/4" unbalanced jack).This signal can be routed to a powerampor a FX device via a shielded cable.LINE LEVELThis control feature determines the level ofthe LINE outputs 25, 26, 27 and 28. Theinstrument output (32) signal can also beamplified to 15 dB if required.29FX LOOP RETURN: RIGHTSignal input right stereo channel for theFX Loop. Connect this input to a signalprocessor’s right output/send jack via ashielded cable with 1/4" plugs.30FX LOOP RETURN: LEFTSignal input left stereo channel for theFX Loop. Connect this input to a signalprocessor’s left output/send jack via ashielded cable with 1/4" plugs.31INSTRUMENT OUTPUTFX LOOP SENDOutput for patching the preamp signal to apoweramp input or the input of a anotherpreamp or signal processor/FX device.Ensure you use a short shielded cable forthis signal circuit.AUXILIARY INPUTSupplentary preamp input. This circuit is routedin series with the input located on the frontpanel and is used for patching the setup to a19" rack. The front panel input has priority. Inother words, when you insert a plug into thefront panel jack (1), the signal routed in via theAux. Input (33) is interrupted.33The INSTRUMENT OUTPUT (32) delivers a signal similar to the one generated by a guitar'spickups when the preamp is active (PREAMP DEFEAT switch Off), i.e. a high-ohm signal at about the same level as a guitar signal. This feature is relevant when you want to establish the same conditions via a bypass circuit (guitar signal to the INSTRUMENT OUTPUT) for further signal processing, for instance by an FX device, another Preamp connected in series or a poweramp.You can connect a signal processor between the INSTRUMENT OUTPUT (32) and the FX LOOP RETURN jacks (30) and (31) or directly between the LINE OUTPUTS (27) and (28) and a stereo poweramp's inputs. There is a substantial difference between these two applications:When you connect the Processor to the FX LOOP, the send signal is identical to the guitar signal when the preamp is in defeat mode and the preamp signal when the defeat mode is off. The send level only is influenced by the settings of the volume controls in this case.The level of the master output signal routed to the LINE outputs can be increased via the LINE LEVEL (29) pot.However, when you connect the Processor between the LINE outputs and the poweramp,the input (Send) signal to the FX device can be increased via the LINE LEVEL (29) pot and you have two Send signals (left, right) available. This option is recommended for low impedance (0 dB)FX devices that are not equipped with a variable input.Technical DataCaution: Replace fuses only with others of the same rating!INSTRUMENT: -10 dB max. 0 dB LINE OUT: -10 dB max.15 dB Output level (0 dB => 1Veff)Tubes:approx.4 kgV1 => ECC83/12AX7 FirstQuality V2 => ECC83/12AX7 selected Dimensions:Weight:19", 1 rack spaces, depth: 260 mm INPUT: -20 dB max. -3 dB Input level(0 dB => 1Veff) 2 x 1,5 Watts at 4 OhmsHeadphones poweramp:Power Consumption: approx. 16 Watts max.Fuses100 & 120 Volts 400 mAM 500 mATAC Mains: external:internal:230 Volts 200 mAM 250 mATM => medium, T => slowchanged!Internal Signal-path:INSTRUMENTHandling and CareProtect the preamp from mechanical knocks (tubes!).Let the preamp cool down before you transport it (approx. 10 minutes).Tubes need about 20 seconds to warm up after you switch the power on.Avoid storing the preamp in damp or dusty rooms, they are hard on jacks, switches and potentiometers.criteria) to avoid microfonic properties, undesireable noise and feedback.W e r e s e r v e t h e r i g h t t o m a k e u n a n n o u n c e d t e c h n i c a l u p g r a d e s !ENGL Ger ätebau GmbH, Germany; Internet: Text, design, grafics and layout by Horst Langer。
