You'll get big sound and functionality in a small package when you use this 2-Channel Bluetooth® Amplifier from Monoprice!
This stereo amplifier delivers 20-watts per channel into 4-ohm loads, which is more than enough to drive most bookshelf speakers. It can also be bridged to produce 40 watts into a single 8-ohm load. It features a -95dB signal-to-noise ratio and a 20Hz to 20kHz (-3dB) frequency response.
The amp features two line level inputs (one RCA, the other 3.5mm TRS), as well as Bluetooth connectivity, so you can wirelessly stream music from your phone. It has a built in microphone and the Bluetooth HFP profile, allowing it to be used to answer or reject incoming phone calls.
The included IR remote control allows you to select the source, control the volume level, set mute on/off, power the unit on/off, adjust the balance, and adjust the treble and bass response. You can also control the amplifier using an RS-232 connection from a PC. The manual includes all the codes necessary for full RS-232 control.
It has an optional loudness circuit, which dynamically boosts the low and high frequencies at low volume levels. It also features an optional limiter circuit, which reduces input sensitivity as the amp approaches maximum output level, thereby preventing distortion and clipping.
