Rack Mount Instructions
Elevated Operating Ambient- If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (50°C) specified by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not created by improper or uneven mechanical
loading.
Reliable Earthing - Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g. use
of power strips).
Troubleshooting
Unit does not power up
Check that the mains power source is switched on
Replace mains fuse with T 1.6 Amp HBC (ceramic)
If unit still does not power up, refer to vendor
No audio at the line output
Check all connections to the unit. For example, check that the input and
output are plugged into the same channel
LEDs do not respond to toggle switches
Set the unit to ‘internal control’ mode; LEDs will light red
No gain reduction at any setting
Check that the relevant channel is set to ‘in’. The unit must be set to
‘internal control’ mode if you are
not
using an external control source; LEDs
light red for internal control mode
Check that the relevant channel is set to ‘compress in’ and/or ‘limit in’
Turn the compress and/or limit threshold control to a lower setting
Both channels shows the same gain reduction at all settings
If you need both channels to operate independently, set the unit to ‘mono’
mode
