Guided Tour - S83 Main Section
output signal. At the fully clockwise (“+10”) position, approximately 10 db of gain
is being added by the mixer to the output signal. For more information, see the
“Setting Up and Using the S83/S63” section in this manual.
5: Phantom switch - When this switch is pressed in, the S83 delivers 48 volts
of phantom power to pins 2 and 3 of all XLR microphone connectors in all eight
channels. WARNING: Only use this switch with the S83 powered down. Before
turning phantom power on, be sure to disconnect all non-microphone signal
sources (such as direct injection boxes) from the XLR mic jacks. Although
phantom power will have no adverse affect on connected dynamic microphones,
it should be used only when one or more condenser microphones are connected
to the S83. Refer to the owners manual of your microphone to determine
whether or not it requires 48 volts phantom power—we cannot assume
responsibility if you damage a mic by incorrectly applying S83 phantom
power. If you’re not completely certain that one or more connected mics require
48 volts phantom power, leave this switch off (its out position).
6: Return 1-2 Level (green) - This knob determines the input level of signal
arriving via Effects returns 1 and 2 (mixed together in mono). This signal is at
unity gain (no boost or attenuation) when the knob set to the 0 position and is
boosted when the knob is turned to the right of 0 and attenuated when turned to
the left of 0. For information on how to properly set this, see the sections in this
manual entitled “Setting Up and Using the S83/S63” and “Using the Effects
Sends and Returns.”
7: Return 3-4 Level (green) - This knob determines the input level of signal
arriving via Effects returns 3 and 4 (mixed together in mono). This signal is at
unity gain (no boost or attenuation) when the knob set to the 0 position and is
boosted when the knob is turned to the right of 0 and attenuated when turned to
the left of 0. For information on how to properly set this, see the sections in this
manual entitled “Setting Up and Using the S83/S63” and “Using the Effects
Sends and Returns.”
8: Reverb Level (green) - This knob determines the level of the return signal
from the internal reverb unit. The amount of incoming reverb signal is increased
as the knob is turned clockwise. For more information, see the “Using the
Effects Sends and Returns” section in this manual.
9: Monitor Level (green) - This knob determines the overall level of the signal
being output from the rear panel Monitor jack. The amount of signal sent is
increased as the knob is turned clockwise. For more information, see the “Using
the Effects Sends and Returns” section in this manual.
10: Headphone Level (black) - This knob sets the level of the signal sent to the
headphone jack. WARNING: To avoid possible damage to connected head-
phones (or, worse yet, to your ears!), always turn this all the way off (to the fully
counterclockwise “0” position) before plugging in a pair of headphones—then
raise the level slowly while listening. The Headphone Level has no effect on the
final output level.
11: Headphone jack - Connect any standard stereo headphones to this jack
(via a standard 1/4” TRS plug) for private monitoring of the final output signal.
NOTE: The S83 main speaker outputs are not muted when headphones are
inserted into the Headphone jack—to monitor your main mix in privacy, it is
necessary to set the Main Level control to its fully counterclockwise (“∞”)
position. The built-in S83 headphone amplifier delivers 20 mW into 8 ohms.
