ART – MX821Eight Channel Mic/Line Mixer with Tone ControlOPERATION MANUALINTRODUCTIONThe MX821 is a versatile rack mount mixer combining eight independent input channels into a single mono line level mixed output.Essential features include: XLR microphone and 1/4 inch line level inputs, Level and Tone controls, and switch-selectable +48 Volt phantom power on each channel. Main output is balanced low impedance. Additional Pre-Fade output and Aux Buss input jacks allow patching of multiple MX821’s when more channels are needed.Built in power supply and single high 19-inch rack mount format allows for easy installation and reliable long-term operation.FEATURES:•Eight Independent Input Channels•Level and Tone Controls on each Channel•Balanced XLR Microphone and 1/4-inch Unbalanced Line Inputs on each Channel•Full +48 Volt Phantom Power on XLR inputs with DIP Switch for each Channel•Balanced TRS 1/4-inch Main Output Jack with Master Level Control•RCA-type Pre-Fade Output Jack (Not Affected by the Master Level Control)•RCA-type Aux Buss Input Jack for Channel Expansion•Solid Single High Rack Mount Chassis w/ Built In Power SupplySPECIFICATIONS:•Input Connections: XLR-F balanced (8), 1/4-inch unbalanced (8), RCA (1)•Output Connections: 1/4-inch balanced TRS (1), RCA (1)•Input Impedance: 2K Ohms Mic, 20K Ohms Line, 10K Ohms Aux.

(2.9kg)OPERATIONa) Verify proper voltage selection on the IEC style power connector for your location. Connect the AC cord to a grounded AC outlet.b) Connect low-impedance microphones to the XLR sockets.c) Connect shielded unbalanced line inputs to the ¼” inch jacks.d) For microphone channels requiring phantom power (for condenser microphones) set the appropriate PHANTOM POWER DIP switches in the down position. Do not engage phantom power on a channel unless it is for a condenser microphone.e) Switch on the power and set the MASTER LEVEL to the ½ way setting, then adjust the channel LEVEL controls as required for the best mix and level. Adjust the channel TONE controls for the desired balance of lows and highs. Center setting is neutral.f) Re-adjust the MASTER LEVEL as required for best overall signal level.g) To patch two MX821’s for 16 channel input operation, run a shielded, unbalanced RCA type patch cable from the PREFADE OUT jack on mixer A to the AUX BUS INPUT jack on mixer B. Note that only the MASTER LEVEL on mixer B will now function.h) To convert the ¼” line input on any channel to a direct line output for that channel, unplug the MX821’s AC cord from the wall and remove the top cover. Inside you will see a row of jumpers. Move the jumper for the desired channel to the left, when viewed from the front. Now that channel’s line input is converted to a direct line output and may be connected to the input of another mixer. Any converted channel is still included in the main output mix as well. Do not connect the output of a mixer or any other signal source to the ¼” jack on this channel now or the channel may sustain damage. Be sure to replace the lid before plugging the unit back into the AC socket.WARNINGSAll operating instructions should be read before using this equipment.To prevent the risk of electrical shock, do not remove the cover.There are no user-serviceable parts inside.
