40W Stereo Amplifier w/Bluetooth
Compact, powerful 20W x 2CH amplifier is perfect in any situation where a pair of speakers need to be powered. Internal Bluetooth receiver adds convenience when any portable device is used as a source.

Specifications Top

Compact amplifier is rugged enough for commercial environments where 100% duty cycle is required, with the finesse expected in a compact high end system found in an living room, den or other small listening area.

Efficient Class D design occupies little space and requires no ventilation, yet provides 20W RMS x 2CH output. It accepts two line level sources, with the internal Bluetooth receiver acting as the third input. Switchable limiter provides protection against being over driven in permanent installations. Switchable loudness contour greatly improves overall sound quality when played a low levels in office or home environments. 9-pin serial interface allows RS-232 control by external devices.

    Looks, functions and sounds great

    Overall: 5 out of 5

    I also thought the $100 price tag was a bit steep, but after setting this up I am happy with every dime I spent. This thing looks very cool, operates flawlessly and sounds awesome. The metal case is rock solid, feel of the controls is great, display and LED's all look good. The remote is nicely made and feels great. Bluetooth functions perfectly and has longer range than any other device I've seen.
    If I were to want anything, it'd be maybe a bit more power. Otherwise, perfect!

    Thought the price of $100 was just a bit steep, but this works very well. Pairs with a variety of BT devices with no problems whatsoever, sound quality is great. Thick metal enclosure has solid, quality feel. Switchable loudness and electronic bass, treble and volume controls are a nice touch. I highly recommend.

    Works great, I have used this almost daily now for about a month. Unit stays powered on 24/7 ends up being used for about 9 hours a day. Sounds very good, amplifier quality is excellent. Bluetooth pairs with my old school iphone4 with no problems.
    HIghly recommend.

    Bluetooth (?) amplifier

    Overall: 1.5 out of 5

    Works all right as a simple, low-power amp, but the bluetooth receiver won't pair satisfactorily with either of my 2 Samsung tablets (2.0 & 3.0). Every 20 seconds or so, the amp sends out the "bluetooth beeps", disrupting whatever I'm listening to. If I'd known I was going to need to plug in the input signals, I could have bought a stronger amp for less money.
