a. AUX Send/Return Function and Operation (13) AUX RETURN

(31) AUX RETURN CONTROL

The Aux Return jack enables a convenient input to the left and right Master Mix busses. If you connect a signal to the Return jack, the Aux Return will operate in mono and the sig- nal will be routed to the Aux Return Control (31) and then mixed into the left and right Master Mix bus. The Aux Return is multi-functional. It may be used for returning the outputs of effect units such as Tape Returns from a multi-track recorder, or as extra instrument inputs such as from a MIDI keyboard.

(12) AUX SEND

(30) MASTER AUX SEND CONTROL

The Aux Send jack is the unbalanced output for the signals from the Aux bus. It is pre-fader. This signal can be sent to the input of an effects processor, multi-track recorder, or used for any other line-level auxiliary purpose, such as monitor feeds. The Aux Send level is adjusted by the channel Aux Send controls (7) and the Master Aux Send control (30). When the Aux/Mon switch (26) is in the depressed IN posi- tion, the Aux send also functions as the mono output of the Master Right Channel bus. (See also Master Mix Function and Operation below)

The final Master Mix is output directly to the Main Speaker outputs (42). These L/R outputs provide 200W at 4 ohms for powering P.A. speakers rated for this power or more. Channel A and B parallel outputs allow multiple speaker setups. You can also access this Master Mix by utilizing the send function of the Stereo Master Inserts (see below). The Record Out

(17)jacks output the Master Mix post-Stereo Master faders (27A, 27B) and are pre-Master EQ (22) and pre-Stereo Master Inserts (14,15). These outputs are RCA jacks, and designed primarily for inputs to tape recorders, etc.

The output level routed to the Speaker outputs and REC out- puts is determined ultimately by the setting of the Stereo Master faders (27A, 27B). The Master Mix (signal on the L/R main busses) is the sum of the signals routed from all the channels and also the inputs from the EFFECTS and AUX busses and the TAPE Input (16). The level input from the Tape In (16) is adjusted with the Tape In Level control (29). The level of signal routed to the Stereo Master faders (27A,27B) from DAT, tape decks, CD players, etc., input to the Tape Input (16) is determined by the setting of the output volume control of the audio device being connected and the Tape In Level Control (29), so care must be taken in adjust- ing these levels so as to achieve proper balance in the final mix and to prevent overload distortion. The 10-stage LED Output Meter (19) can be used to maintain proper levels in the master mix.
