CONTROLS AND CONNECTIONS

2. STEREO INPUT SECTION
(13) L (MONO) LINE INPUT
On stereo input channels 9-
16, the 1/4" line inputs are
designed for stereo or mono
line-level signals such as
those from keyboards, drum
machines, CD players, tape
decks, or samplers.
However, these inputs can
also be used as standard
mono line inputs by connect-
ing the signal to the L
(MONO) line in. This signal
will be routed equally to the
BAL control and the left and
right outputs in the same
way as the standard line
input channels. For the
stereo line inputs the mono
channel PAN (7) control is
replaced by the BAL
(Balance) control. See also
BAL CONTROL (15) above.
(14) R LINE INPUT
When using channels 9-10,
11-12, 13-14, or 15-16 as
stereo input channels, the
left signal should be con-
nected to the L input and the
right signal to the R input.
These signals will be routed
to the AUX, EQ and Channel
fader controls equally and
will retain their stereo sepa-
ration. The AUX, EQ, BAL,
and Channel fader controls
all function the same as
those on mono input channels 1-8.
When a stereo signal is input to a stereo input channel, these
controls will affect the left and right signals equally. The
Stereo Line Input jacks are 1/4" TRS balanced phone jacks,
Tip = positive (+), Ring = negative (-), Sleeve = ground.
(4) TRIM CONTROL
The stereo Trim control operates in the same manner as the
mono Trim control. The stereo inputs are designed for any
line level signal. Most line level sources such as MIDI instru-
ments and effects units will have their own output level con-
trol. However any added adjustment necessary for proper lev-
eling can be done with the Trim control.
(5) EQUALIZERS
The stereo channel EQ’s
operate in the same manner
as those in the mono chan-
nels. The left and right signals
will be affected equally. A
stereo equalizer is generally
preferable anyhow to using
two mono equalizers when
equalizing a stereo signal as it
avoids possible discrepancies
between the left and right set-
tings.
(6) AUX SENDS
These are the same as for the
mono channels. Note that a
mono sum is taken from the
stereo input.
(15) BAL CONTROL
For a mono input to the
L(MONO) input the function of
the control is the same as the
PAN (7) controls of the mono
channels. However, when a
channel is run in stereo, this
control functions as a Balance
control, determining the rela-
tive Balance of the left and
right channel signals being
sent to the left and right
Master Mix buses. For exam-
ple, with the Balance control
turned fully clockwise, only the
right portion of the channel’s
stereo signal will be routed to
the Master Mix. Balance also
determines the relative amount of left and right channel sig-
nals being sent to buses G1, G2 respectively when the G1-2
Select switch (11) is engaged.
(8) PEAK LED INDICATOR
(9) PFL SELECT SWITCH
(10) L-R SELECT SWITCH
(11) G1-2 (GROUP) SELECT SWITCH
(12) CHANNEL FADER
This has the same function as for the mono channels. See
MONO INPUT SECTION.
