Check mains is connected and switched on at the socket
Check that the mains fuse is not blown – refer to qualified service personnel
If the fuse is blown, check that the loop contacts were not shorted out
Check input connections are OK and that a signal is present on the input
Check that the loop is intact and connected to the amplifier properly
Increase channel level controls and Loop current if necessary
Check for large metal structures within the architecture close to the loop
Avoid changes in height of the loop cable (running over door frames etc.)
Ensure that the loop cable is twisted between the loop and the loop amplifier
If necessary, form a cancellation loop to avoid affecting other equipment
Ensure that the alarm contacts are not accidentally shorted out.
Loop current or input levels may be too high, decrease the relevant controls
Check that the loop is not shorted or grounded at any point
Increase input signal, channel levels and loop current controls as needed
If there are metal structures nearby, increase metal loss correction level
Use Bass and Treble controls to help improve intelligibility
