Powering the system

The following details the recommended power up and power down procedures for the
system.
Note: If you are in any doubt as to how to switch the rack units on/off, refer to their
operator manuals.
>> To power up the system
Important Note:
DO NOT switch on the speaker sub-system until after the start-up of the
system has been completed.
After all system interconnections have been made (see "Wiring instructions" on
page 38), start up the system by doing the following:
1
Make sure that all of the system equipment is switched off, such as the control
centre, speaker sub-system, DL371 Audio System Engine unit and I/O unit(s).
2
Switch on the control centre (see "To switch on the control centre" on page 43).
3
In the master bay of the control centre, move all of the monitor and master
channel faders to the minimum position and mute all of the master channels (see
section F in Figure 5 "Main areas of the control surface" on page 29).
4
Power up the other system equipment, such as the DL371 Audio System Engine
unit and I/O unit(s). This can be done in any order you like.
5
After the status indicator at the top of each GUI screen has
changed to green (shown right), switch on the speaker
sub-system.
6
Switch on the audio source and start playing the audio.
7
On the control centre, check that the audio inputs are routed to the master
channels. Then, unmute the master channels and gradually increase their faders
while listening to the sound levels from the speakers.
If there is no sound at all coming from the speakers when the faders are at maximum,
move the faders to below the 0dB level and check if the audio is muted somewhere
along the input paths and also check that the individual speakers are switched on. If
there is still no sound from the speakers, see "No audio" on page 393.
>> To power down the system
Important Note:
BEFORE switching off any of the system components, don't forget to mute the
audio from the speakers and switch off the speaker sub-system.
1
Mute the audio from the speakers and switch off the speaker sub-system.
2
Switch off the I/O unit(s).
3
Switch off the DL371 Audio System Engine unit.
4
Switch off the control centre (see "To switch off the control centre" on page 43).
