By David Perry

Why is my amp not getting any power?

If the remote turn-on wire doesn’t have power, your amp won’t turn on. If it doesn’t, you’ll want to check for any inline fuses and verify that the wire isn’t loose, corroded, or shorted out somewhere. If the remote and power wires both check out okay, the next thing to look for is continuity on the ground wire.

When your subwoofer is on the high-level input, it’s seeing exactly the same signal as your speakers, with no timing differences at all. The RCA subwoofer output on a preamp is going to be ever so slightly out of sync with the amp’s speaker outputs.

Can a subwoofer be connected to a preamp?

In spite of the name, a ‘subwoofer out’ isn’t the best way to connect a subwoofer to a quality music system. The preferred method works even if a preamp doesn’t have special subwoofer or preamp outputs, however, you do need a subwoofer that can accept a “high level” (also called “speaker level”) input.

Is there a subwoofer in a multichannel processor?

We’re used to seeing subwoofers in home-cinema systems, and multichannel preamps and processors nearly always have a subwoofer out. In fact, home-cinema subwoofers are given their own channel, called the .1 or the LFE output (low-frequency effects).
