ESU1808 ESI
There are three different areas in the panel:
A. input section
The input section contains input level meters for each input, divided into 3 groups. Analog In 1~8
show incoming signals for the analog inputs on the front panel of ESU1808. Analog In 9~16 show
incoming signals for the analog inputs on the rear panel of ESU1808. Dig In shows the incoming
signal from the S/PDIF digital input.
The MON button under Dig In allows you to enable the input monitoring for the S/PDIF input. If
MON is activated (indicated by a blue color), the input signal from the digital input is audible via
the MIX OUT output on the back panel of ESU1808. In this case, audio playback via channel 7/8 is
not possible at the same time. More details about monitoring input signals and the MIX OUT output
can be found in chapter 6 of this manual.
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.
B. output section
In this section you can control the playback volume for the signals from your audio applications
individually for each channel. The faders are aligned in stereo channel pairs (i.e. Analog 1/2,
Analog 3/4, Analog 5/6 and Analog 7/8).
Each channel has its own volume slider that can be adjusted in 0.5dB steps. With the mute button
(M) under each channel, playback can be muted or unmuted again. The LINK button under a
channel pair links the left and right volume slider, allowing you to control the stereo volume of the
specific channel simultaneously for left & right channels.
The MIX button controls the monitoring of the playback signals for output channels 1~8. If MIX is
enabled (indicated by blue color), the playback signals from channel 1~8 are mixed together and
sent out through the MIX OUT output on the back panel of ESU1808. More details about
monitoring in general and the MIX OUT output can be found in chapter 6 of this manual.
Caution: when you activate or deactivate the MIX 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.
Via the S/PDIF OUT selection above each fader, you can select which signal will be sent out
through the digital S/PDIF output of ESU1808. You can select any of the available stereo channel
pairs (i.e. Analog 1/2, Analog 3/4, Analog 5/6 or Analog 7/8).
C. output format section
Located under the status section, this area allows you to switch between the Professional and
Consumer status bit for the digital S/PDIF output under Digital Format.
Below that, you can define the Output Level for the analog outputs. ESU1808 can send out signals
at –10dBv or +4dBu reference level. Make sure the setting matches the input of the device you have
connected to ESU1808. All outputs are switched simultaneously.
