Why is there no sound on my B&K Reference 220M Amplifier ('on' LED not illuminated)?
If there is no sound and the 'on' LED is not illuminated, here are a few things to check: * Ensure the power cord is properly plugged in. * Verify that the AC power source is on, checking the AC switch or fuse. * Inspect the AC power inlet fuse for any shorts or overloading. * Confirm that the control switch is in the correct position.
What to do if there is no sound on some channels of my B&K Reference 220M ('on' LED illuminated)?
If the 'on' LED is illuminated but there's no sound on some or all selected channels, try the following: * Tighten, repair, or replace any loose or faulty speaker leads. * Tighten, repair, or replace any loose or faulty line stage to amp cables. * Tighten, repair, or replace any loose or faulty source to line stage cables. * Check all switch settings to ensure the line stage or source is correctly selected.
What to do if my B&K Reference 220M channel sounds distorted and low in output?
If a channel sounds distorted and has low output, the rail fuse inside the amplifier may have blown. Replace the blown rail fuse inside the amplifier.
Why does my B&K Amplifier sound lack direction and have weak bass?
If the sound lacks direction and the bass is weak, it could be that the speakers are connected out of phase. Check the connections to ensure that cables are connected (+) to (+) and (-) to (-).
Why is the output from my B&K Reference 220M so low?
If the output from the amplifier is low, check the balanced switch position. If you are using unbalanced inputs, ensure the balanced switch is not in balanced mode. Put balanced switch in correct position.
How to fix loud hum or buzz on my B&K Reference 220M Amplifier channels?
A loud hum or buzz on one or more channels may be due to a poor ground connection in the interconnect cables. Check all connectors and repair as necessary.
