Finally my Pioneer speakers work perfectly with this PTA44BT amplifier. The delivery is very fast!!! Thanks a lot!

This was just what I was looking for. The 4-channel output matched the speaker set-up I pre-wired when I built my office space years ago. I was using a 4-channel speaker selector switch with two prior stereo receivers that eventually died. Tremendous feature set for the price and the unit is a very solid substantial piece of gear. The Bluetooth (a game changer compared to the old equipment) was easy to pair with my iPhone. I the FM radio section was surprisingly sensitive and picked up many stations with the included basic mono-wire antennae. I only listen to one FM station, so fortunately the previously tuned station stays tuned when the input mode changes. The volume could be way louder than my needs and sound quality was fine. One review mentioned, tight, not smooth volume control knobs of channels A B C D. I noticed that on a couple of mine but noticed that the knobs were pushed on a bit too much and contacting the face of the unit. Pulling the knobs outward (as if to remove them) fixed that and the smooth rotation of each knob was realized. I was curious as to the energy used so I measured the watts with a meter. As expected, the watts varied with volume: Plenty loud was around 30w, with ~20w for normal low background music. "Cranked" was close to 100w and probably unpleasant for most. A more energy efficient replacement in my situation.

I bought this for my 4 ceiling speakers. no issues so far, works perfectly. Sounds great. Highly recommended

Excelente amplificador, cumple su función, ya lo conecte y sirve perfectamente y se escucha bien, independientemente de las bocinas que tengas. Además tiene una protección para sobrecargas.
