Unregistered guest | I have a TOA amplifier that we use to power 2 pairs of ceiling-mounted speakers in a large room. I also have a microphone at the front of the room for announcements. The problem is that with the current configuration there is one main volume control for both pairs of speakers(on the amplifier). So when I use the microphone at the front of the room the front speakers bleed into the microphone and cause feedback. I need that amount of volume for the rear speakers but the front speakers could be at a lower volume. I was wondering if there was something available that would allow me to have independent volume control for the front and rear speakers while still using the original amplifier. |

Unregistered guest | I would recomend a Russound volume control module. This connects between your amplifier and speakers and allows you to control the volume of that pair of speakers. In your case you would need two volume controls, connect them between the amp and each pair (front and back) and now you have individually controlled speakers. They can be used as impedance matching or non-impedance matching to insure your amp is kept safe and eliminating the need for a speaker selector. I hope this helps. We carry most Russound products and would be happy to help you find what you need. www.digitalhsolutions.com |
