ESU1808 ESI

6.2 Monitoring volume for input channels

The monitoring section on the front panel of ESU1808 controls two gain
knobs (for INPUTS 1-8 and INPUTS 9-16) that allow you to individually
control the monitoring volume for each group of inputs. If you do not want
to monitor any analog input signals, turn these gain knobs to 0. However, if
you want to monitor the signals, turn them to the appropriate level.

6.3 Monitoring volume for playback channels

The front panel monitoring section also controls a separate gain knob labeled
OUTPUTS 1-8. Use this gain knob to control the monitoring volume for the playback
signals from your audio applications.
Note: If the MIX function in the Control Panel is enabled and you use MIX OUT as your main
master output, the OUTPUTS 1-8 knob is used to control your master monitoring volume.

6.4 Mono down mix for microphone inputs

The MONO A switch on the front panel allows you to create a mono down mix for the
microphone inputs (input 1/2). As a microphone signal is mono, monitoring a
microphone with a computer audio interface is always tricky: normally you can only hear
the signal on the left (input 1) or right (input 2) channel when monitoring in real time. This is
especially a problem when monitoring with headphones. The solution is a mono down mix that can
be enabled with this button. When activated, both signals from input 1 & 2 are audible on left and
right channels simultaneously.
Note: when using a stereo microphone (connected to input 1 & 2 simultaneously), make sure that
the MONO A switch is disabled.

6.5 Mono down mix for Hi-Z instrument inputs

The MONO B switch on the front panel allows you to create a mono down mix for the
Hi-Z instrument inputs (input 3/4). As a normal instrument signal, e.g. from a guitar, is
mono, monitoring it with a computer audio interface is tricky: normally you can only
hear the signal on the left (input 3) or right (input 4) channel when monitoring in real time. This is
especially a problem when monitoring with headphones. The solution is a mono down mix that can
be enabled with this button. When activated, both signals from input 3 & 4 are audible on left and
right channels simultaneously.

6.6 Monitoring the digital S/PDIF input signal

The MON button (located in the Control Panel) allows you to enable input monitoring
for the signal that is received from the S/PDIF input (input 17/18).
Caution: when you activate or deactivate the MON function while playback is running, a small
click can be heard on all playback channels and the signal is interrupted for a second. This behavior
is normal and not harmful.
