Is it possible to use this amplifier with an 8 ohm mono load. We have single speakers in each classroom would it be possible to bridge the channels?
Asked by: Anonymous
Unfortunately you may not bridge this amp. You may use a single channel for this amp using a 8ohm speaker but the power will be limited to approximately 10 watts.

We'd like to use this device with two 3.5mm sources. (one from the computer located in the room, and a second from an optional laptop.) Is it best to just "merge" the two 3.5mm cables to one for the input (using a 2 to 1 3.5 adapter), our is there an alternate version of this device that may have two 3.5mm inputs as an option? We would use the RCA however the RCA would already be used by a VHS/DVD player in the room.
Asked by: Chad
You could use a 3.5mm Y cable but it would not be ideal. We would recommend using a 3.5mm audio switch.

how do you connect the power cord to the amp? The is no positive negative signs!!! One cord has a stripe on it and the other a bunch of writting.
Asked by: Mitch
The white stripped cable will go to the + terminal.
