Building a multiroom solution with central audio source. The Up2Stream amp is a perfect solution. Note that the mono and stereo amps are identical: a jumper block is used to select in which mode to operate.
I bought this to simplify a wireless speaker build, however, I found it lacking power and a few items weirdly placed. All of the external connections are on side, which is good. They are offset which allows the creation of cover plate to expose the connections and hide the electronics, but the speaker connection is pin connector, not an external connector like an RCA or Banana Jack. And if you're using as part of a powered, stand alone speaker, you have to run the wires out the back and then back into the speaker. I simply desoldered it and directly connected the speaker wire internally. The other item is that the LED light AND the infrared receiver are mounted on the other end of the circuit board. So, you can either desolder them and run an extension to make them accessible and visible, OR, you have to purchase another receiver and finagle an RGB LED using the onboard pin connector. Alternatively, you can wire separate colored LEDs to indicate the status using onboard connector. However, I love rest of it. The software seems to be as good as the HEOS software, plus, if you want to customize it using the workbench, you have that ability too.
I have purchased these amps in order to turn my old passive Pioneer speakers into Wifi speakers. With on-off-on switch I managed to create double input on speakers so now they can be used as before connected to my old amp or as a Wifi speakers connected to Up2Stream amp.
I have also added battery power and turned them to completely wireless speakers when used with Up2Stream amps.
Ordered 3 amplifiers, one of them came with a defect, did not work the power button. The seller sent a similar amplifier at his own expense. I checked everything, everything works well! Seller recommend! The only nuance, this is a large power supply, twice as much as the amplifier itself.
A good device, but when used in a pair of two boards, there is a surround effect.
very good seller I recive very fast shipment thanks
