Gain potentiometer defective

Finally attempted to install this unit and found the left channel gain potentiometer to be defective. If it's a new device, why is it falling apart? Not good for $100!

Pros
  • Security & Surveillance
Cons
  • has been damaged

Revainrating 4 out of 5

Improved from the previous version

I think the ergonomics of the a-k4 are better than the a-k3. They fixed the Cat5 connector issue and some other glitches. However, the style is too boxy and the display is now very bright for late-night use. It's an improvement, sure, but still not perfect.

Pros
  • Access control keypads
Cons
  • Not as thick as other models

Excellent quality with additional features

The Russound A-K4 Amp Keyboard not only works as a local ABUS speaker amplifier, but also has additional unbalanced line level outputs that I use to connect to a subwoofer amplifier. The added bass from the subwoofer fills in the lack of resonance from the ceiling speakers and the overall effect is amazing. Good product!

Pros
  • Electronics
Cons
  • Legacy
