ART – MX622

Six Channel Stereo Mixer with EQ and Effects Loop

OPERATION MANUAL

The MX622 is a versatile mixer combining three b mono balanced XLR input includes fully variable Input gain, Mic/Line switch, Clip indicator, and selectable 15 Volt Phantom power. An external effects loop section provides a mono Send from the three Mic/Line channels to external equipment and stereo Returns with Effects Level and In/Out switch. Three stereo line level inputs are also provided via RCA type jacks with separate Level controls for each stereo pair. Stereo Record output RCA jacks provide full-level signal of the entire mix at all times. Main outputs are stereo balanced ¼” TRS with Master Level and full range Bass/Treble equalization. The built in power supply and single high 19” rack mount format allows for easy installation and reliable operation.

FEATURES:

 Three balanced XLR inputs with separate Mic/Line switch, Level control and Clip Indicator  Three pairs of RCA stereo inputs with separate Level controls  Selectable 15 Volt Phantom power for each Mic channel  Balanced ¼” TRS Main outputs with Master Level control  Versatile Bass and Treble equalization on Main outputs  Stereo Record Out RCA jacks  Effects Loop with Effects Level control and In/Out switch  ¼” Effects Send with stereo Returns

a) Verif

y proper voltage selection on the IEC style power connector for your location. Connect the AC cord to a grounded AC outlet. b) Connect Mics or balanced Line inputs to the XLR sockets. c) For Mic channels requiring phantom power (for condenser mics), move the DIP switch to the down position to activate phantom power for each XLR input. d) Set each Mic/Line switch as required for the type of input signal level. e) Connect stereo signal sources (CD, tape/MP3 player, etc.) to input channels 1, 2, and 3 using RCA type unbalanced cables. f) To patch-in effects, using three shielded TS (unbalanced) cables, connect the Efx Loop Send jack to the input of the effects unit and the unit’s stereo outputs to the Left and Right Efx Loop Return jacks. Once the MX622 is connected to the main mixer, tape deck, computer interface, or power amplifier, apply a test signal, set the Efx Loop In/Out switch on the front panel to the IN position, and adjust the Efx Level control for the desired effects intensity. g) The Left and Right Efx Loop Return jacks may alternately be used as a stereo line input with its own level control and In/Out switch. h) Connect either the ¼” balanced Left and Right Main Output jacks or the RCA Record Out jacks to the input of the mixer, tape deck, computer, or power amplifier with the appropriate balanced or unbalanced, shielded cables. i) Switch on the power and set the Master Level to the ½ way setting, then adjust the input channel Level controls as required for the best mix and level while checking the Mic/Line channel CLIP LEDs for activity. Turn down any channel with CLIP activity until the LED is on during extreme peaks only. j) Adjust BASS and TREBLE controls for the desired balance. The mid position has flat frequency response. k) Re-adjust the Master Level as required for best signal level.
