Connections to a preamplifier using Y cables

If your preamplifier does not have a sub/LFE output, you can use “Y” cables to send its main outputs to both the subwoofer and your amplifier.

The subwoofer will play the low frequency range and your front speakers will play the full range.

Although bass is commonly distributed evenly between left and right channels (L+R bass), movie soundtracks often contain differential (L-R) bass. The opening scene in “Top Gun”, for example, has loads of L-R bass information. If this is not preserved, the bass in these scenes sounds anemic. The Sunfire Subwoofer utilizes differential gain on the left and right inputs to retain both the L+R and L-R information. Therefore, systems which do not have a dedicated sub/LFE output should use both the left and the right inputs as shown, for the greatest bass impact.

An alternative connection method without using Y cables is shown on the next page.

If your preamp/receiver has a dedicated sub/LFE output, then only the Left (Mono) input is used, as shown on the previous page.
