(24) L (MONO) LINE INPUT
On stereo input channels 3-6, 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 connecting 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
mono input channels. For the stereo inputs, the mono channel
PAN (8) control is replaced by the BAL (Balance) control. See
also BAL Control (17) below.
(25) R LINE INPUT
When using channels 3-6 as stereo input channels, the left
signal should be connected to the L input and the right signal
to the R input. These signals will be routed to the AUX, EQ
and Channel Gain controls equally and will retain their stereo
separation. The AUX, EQ, BAL, and Channel Gain controls
all function the same as those on the mono input channels.
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” unbalanced phone jacks
(Tip = positive (+), Sleeve = ground. The input signals to
these jacks can be either balanced or unbalanced.
(14) EQUALIZERS
The stereo channel EQ’s operate in the same manner as
those in the mono channels. The left and right signals will be
affected equally. A stereo equalizer is generally preferable to
using two mono equalizers when equalizing a stereo signal as
it avoids possible discrepancies between the left and right
settings.
(15) AUX SENDS
These are the same as for the mono channels. Note that a
mono sum is taken from the stereo input.
(16) PRE/POST SWITCH
This switch selects whether the AUX SEND signal is Pre or
Post Gain control.
(17) BAL CONTROL
For a mono input to the L (MONO) input the function of the
control is the same as the PAN controls (8) of the mono
channels. However, when a channel is run in stereo, this
control functions as a Balance control, determining the
relative Balance of the left and right channel signals being
sent to the left and right Master Mix buses. For example, with
the Balance control turned fully clockwise, only the right
portion of the channel’s stereo signal will be routed to the
Master Mix.
(18) CHANNEL GAIN CONTROL
This has the same function as for the mono channels. See
MONO INPUT SECTION.
