Surround Back Speakers

Many preamplifier processors feature additional outputs for surround back speakers. These create a wonderful sense of realism in surround effects during playback of Dolby Digital EX, Dolby Pro Logic IIx, and DTS ES.

Ideally, all the surround speakers should be of the same make and model as the surround speakers, and fitted at similar heights to produce a smooth continuous sound field.

Subwoofer Location

Although subwoofers are normally configured with their own internal power amplifier (rather than using the MPS- 1), we know you will probably use at least one subwoofer in your home entertainment system. As such, it’s important to understand correct subwoofer placement so that you get the most out of the other speakers connected to the MPS-1 Modular Power Amplifier.

A subwoofer typically sounds best in a corner with at least

5 feet of wall to either side. Due to the short wavelengths of high-frequency sounds, they don’t interact strongly with the size and shape of a room. Lower frequencies long wave- lengths that can cause “Standing wave” problems. Placing the subwoofer in a corner usually creates the best possible situation for the sound to interact with the room, allowing

even distribution of the bass frequencies. Often the corner that offers nearby placement to the front speakers may yield the best results, but you should try several locations before settling on just one.

The best location for a single subwoofer can be found by playing a couple of different low frequency test tones (or some music with heavy sustained bass passages) and proceeding with the following easy 1-2-3 process:

1.Place the subwoofer right on the seat of your couch or listening chair.

2.You can then either run the calibration (noise) signal through it, or simply plug the analog outputs of a CD player directly into your subwoofer’s low-level inputs. Turn down the subwoofer’s volume level before turning on the CD, then play the test tones or some music with heavy sustained bass passages.

3.Walk around the room, standing in all the positions where you might be able to place the subwoofer. Again, this is usually near the corners of the room. Try locations fairly close to the front speakers.
