5.5 Aux Send Outputs
The Aux Outputs are used to
drive monitors, effects processors, re-
cording 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" un-
balanced. Return 1 is stereo with a
left and right input, while Return 2 is
mono. To use return 1 as mono, con-
nect only to the Right return 1 input.
5.7 Tape/CD Input - Tape Output
The stereo inputs on RCA
connectors have a nominal operating
level of -10dBu to match most tape
decks and CD players. The tape out-
puts 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 pro-
vide 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 de-
signed to drive up to +24dBu into 600 ohm loads. Be-
cause 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 out-
puts will not change as the load changes, any transformer
used in an audio path is affected by its termination im-
pedance. Since line level inputs on audio devices are
typically 10K
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 Main Outputs
These Main Outputs are also controlled by the
left and right master. They are 1/4" pseudo-balanced TRS
jacks with a nominal operating level of +4dBu into any
load.
