PROBLEM: Distorted sound
When input levels to the XT-15Sub amplifier exceed 0.775 V RMS it is possible to produce
system clipping or overdrive. It is still possible to “overdrive” the input section of the enclosure. If
distorted sound is present the following steps should be taken:
1.
Verify that the mixer’s output is not clipping or overloaded. If the output metering
section of the mixing console is continuously in the “red” then the output level should
be reduced. (occasional “red” indications are usually fine and are dependent on the
mixing console’s output capability).
2.
Verify that excessive equalization is not present anywhere in the signal chain.
3.
Verify that AC mains levels are within the required range.
Voltage measurements on the AC Mains should be performed by a licensed
electrician or individual trained in making high-voltage measurements.
PROBLEM: No sound
1. Verify that the amplifier pilot light is on.
2. Verify that there is AC Mains voltage on the AC Mains input to the amplifier.
3. If AC Mains voltage is present, verify that the fuse is not blown.
4. Verify that the correct fuse is inserted. Guidelines for this can be found earlier in this
manual, and on the amplifier panel itself.
NOTE: IF THE FUSE IS BLOWN REPLACE ONLY WITH THE SAME TYPE OF
FUSE. THIS FUSE TYPE IS NOTED ON THE INPUT PANEL NEAR THE FUSE
HOLDER.
PRODUCT SERVICE
There are NO user-serviceable parts inside the XT-15Sub amplifier.
