Check fuse continuity . A 20mm fuse is incorporated into the AC POWER inlet . It is necessary
to remove the power cord before extracting the fuse holder . Test the continuity of the fuse
using a multimeter . A spare fuse is provided in the fuse holder .
Any replacement fuse MUST be of the same rating and type as printed on the rear of
the unit .
COMPRESSION LEDs not illuminating
Check input connections .
Ensure that the input gain levels (INPUT1 or INPUT2) are set to the appropriate level(s). Check
there is sufficient signal level for the required input.
CURRENT LEDs not illuminating
There are many possible causes for this:
• Check the COMPRESSION LEDs are illuminating .
• Check that the CURRENT levels are set appropriately .
• Ensure the ERROR LED is not flashing.
•
Check that the loop cables are connected, terminated correctly and inserted into the LOOP
OUTPUT sockets .
• Check the loops are not open circuit, short circuit, or connected to earth (see instability or high
frequency noise section of Troubleshooting)
• Switch the unit off and turn back on .
Note: You can listen to the actual loop signal by using a pair of headphones plugged into the
monitor socket. Channel A = left, channel B = right
