5 .5 Aux Send Outputs

The Aux Outputs are used to drive monitors, effects

processors, recording devices, or any function which requires

isolated level control from the main outputs . They are pseudo-

balanced 1/4" tip-ring-sleeve .

5 .6 Aux Return Inputs

The return inputs are 1/4" unbalanced . Return 1 is stereo

with a left and right input, while Return 2 is mono . To use

return 1 as mono, connect only to the Right return 1 input .

5 .7 Stereo Line In - Stereo Line Out

The stereo line inputs on RCA connectors (and the

3 .5mm front panel jack) have a nominal operating level of

-10dBu to match most consumer audio players . The stereo

line outputs are -10dBu "pre-master", so they are not affected

by the settings of the Main output controls .

5 .8 Transformer Balanced Outputs

The transformer outputs use male XLR type connectors

and provide total isolation for 600 ohm lines . Pin 1 is ground,

pin 2 is (+), and pin 3 is (-) . These outputs are controlled by

the Left and Right Master levels, with a nominal operating

level of +4dBu .

Note: The transformer-balanced outputs are designed

to drive up to +24dBu into 600 ohm loads. Because of the

nature of an output transformer, the output level increases

as the impedance of the terminating load becomes higher

than 600 ohms. Whereas a "direct-coupled" output stage

like that of the transformerless outputs will not change as

the load changes, any transformer used in an audio path

is affected by its termination impedance. Since line level

inputs on audio devices are typically 10KΩ or higher, expect

a slight increase (2.5dB) in output level when driving high

impedance inputs with the transformer outputs. The output

meters will remain accurately calibrated to the levels present

on the transformerless outputs, regardless of the load on the

transformer outputs.

5 .9 Transformerless Outputs

These outputs are also controlled by the left and right

master . They are 1/4" servo-balanced TRS jacks with a

nominal operating level of +4dBu into any load .

mixer's Sub Inputs for expanded input capacity . The Main

left and right submaster outputs use unbalanced (mono)

1/4" connectors . The Aux submaster outputs use 1/4" TRS

connectors with Aux 1 on the tip and Aux 2 on the ring .

mix busses . Like the main outputs, it is pseudo-balanced with

mixers for expanded input capacity, and include Main left,

Main right, and Aux 1/Aux 2 . Signal to the Sub Inputs is taken

from the Sub Outputs of another mixer, with a nominal level

of +4dBu . The Aux submaster input requires Aux 1 on the tip

and Aux 2 on the ring .
