EFX BUS IN

This connection provides a means of sharing an external effects processor between two MX822s. In

essence, it allows the first mixer to connect directly to the AUX or effects buss of the second mixer.

Using a dual 1/4" TS to single 1/4" TRS cable, connect the separate TS plug ends into the

EFFECTS

SEND outputs of the first mixer and connect the TRS plug end into the EFX BUS IN of the second

mixer (tip is left and ring is right).
Connect your external effects processor as normal to the

EFFECTS SEND and EFFECTS RETURN

jacks of the second mixer. The

EFX SEND controlled signal levels from both mixers will now be

routed to the effects processor. Control the overall effect level using the

EFX RETURN knob on the

front panel of the second mixer.

EFFECTS SEND and EFFECTS RETURN

These jacks allow you connect an external effects processor (such as a reverb unit or vocal

processor) to your MX822 in order to add effects to your mix. Connect the

EFFECTS SEND outputs

to the inputs of your processor and the processor outputs to the

EFFECTS RETURN inputs. Use

cables with 1/4" TS plugs. If the effects processor is mono, connect it to just the

LEFT (MONO) jacks

to route the effect to (and from) both stereo channels. These are unbalanced connections.
The level of each input channel sent to the effects processor is controlled by that channel's

EFX

SEND control. The effects processor's contribution to the total mix is controlled by the EFX RETURN

control.

MAIN OUT

Two male XLR connectors are provided to connect your MX822 to the destination device, such as an

amplifier, powered speakers, or main mixer. These outputs are affected by the

MASTER LEVEL

control. They are balanced connections that may be used to provide excellent noise immunity with

long cable runs.

Headphone Jack

Front Panel Connection

This is a 1/4" TRS stereo jack that will drive a standard pair of headphones. Like the

MAIN EXPAND

OUT connection, the signal to the headphone jack is brought out from a point in the signal path

before the

MASTER LEVEL control, so this control will have no effect on the level provided to the

headphone jack. The

HEADPHONE LEVEL control adjacent to the jack controls the headphone level

independently from the main outputs.

Refer to the block diagram for more information on how these connections are connected internally.
