Why are the peak indicators on my Adastra Amplifier mainly showing overload (red)?
The peak indicators might be showing overload because the loop current or input levels are too high. Try decreasing the relevant controls. Also, check that the loop isn't shorted or grounded at any point.
What to do if there is no power indicator when switched on Adastra Amplifier?
If there's no power indicator when you switch on your Adastra Amplifier, first check that the mains are connected and switched on at the socket. Next, check if the mains fuse is blown. If it is, consult qualified service personnel. If the fuse is blown, also check that the loop contacts were not shorted out.
What to do if peak current indicators are not showing any signal on Adastra Amplifier?
If the peak current indicators on your Adastra Amplifier aren't showing any signal, verify that the input connections are okay and a signal is present on the input. Also, check that the loop is intact and connected to the amplifier properly. If needed, increase channel level controls and loop current.
What to do if siren activated on Adastra Amplifier?
If the siren is activated on your Adastra Amplifier, ensure that the alarm contacts are not accidentally shorted out.
How to fix poor quality audio from the loop on Adastra Amplifier?
To improve poor quality audio from the loop on your Adastra Amplifier: * If there are metal structures nearby, increase the metal loss correction level. * Use the Bass and Treble controls to help improve intelligibility.
What to do if I notice dead spots within induction loop field of Adastra Amplifier?
If you notice dead spots within the induction loop field, check for large metal structures within the architecture close to the loop. Also, avoid changes in height of the loop cable, such as running it over door frames.
How to stop loop field interfering with other audio equipment from Adastra Amplifier?
To prevent the loop field from interfering with other audio equipment when using the Adastra Amplifier, 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.
