2. STEREO INPUT SECTION
(13A) 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 standard line input channels. For the stereo
inputs, the mono channel PAN (6) control is replaced by the BAL
(Balance) control. See also BAL CONTROL (14) below.
(13B) R LINE INPUT
When using channels 3-4, 5-6 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 Inputs jacks are 1/4" TRS balanced phone jacks, Tip =
positive (+), Ring = negative (-), Sleeve = ground. The input
signals to these jacks can be either balanced or unbalanced.
(4) 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 anyhow to using
two mono equalizers when equalizing a stereo signal as it avoids
possible discrepancies between the left and right settings.
(5) AUX/EFF SEND
These are the same as for the mono channels. Note that a mono
sum is taken from the stereo input.
(14) BAL CONTROL
For a mono input to the L (MONO) input the function of the control
is the same as the PAN controls (6) 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.
(8) CHANNEL GAIN CONTROL
This has the same function as for the mono channels. See MONO
INPUT SECTION, page 6.
