Four independent stereo headphone amps in a half 1RU package.

The 4-Channel SM Pro Audio Q-AMP Enhanced Headphone Amp delivers high-quality audio in a stylish, small-footprint unit. Upgraded to include SM Pro Audio's E-Series circuit design improvements, the Q-AMP demonstrates how SM Pro Audio's compact Value series of audio products has received a major revision in terms of appearance and performance.

E-Series circuit design, component selection, and manufacturing offer an additional level of quality to the already successful HP4V.

The headphone amp is housed in a stylish extruded aluminum external chassis that can be rackmounted using SM Pro Audio's RM-1 single unit rackmount adaptor. A single Q-AMP can be mounted in the center of the rack, or 2 Q-AMPs can fit side by side. SM Pro Audio includes robust connectors for all of the Q-AMP headphone amp's inputs and outputs.

Features
  • Four independent, high-power stereo amplifiers in half-1RU package
  • High-quality audio even at extremely high volume levels
  • Two independent stereo input sections
  • 1/4" (6.5mm) and 1/8" (3.5mm) stereo headphone outputs per channel

junk

Comments about SM Pro Audio Q-AMP Enhanced 4-Channel Headphone Amp:

Once again ... just junk.
This headphone amp failed in two days. One channel went out and then another a few days later. I called SM Pro Audio, the manufacturer, and have never had such a terrible experience. That's what I get for trying to save a few dollars. It's nothing but an ashtray. Get something else guys.
You can tell the board mount input jacks are just junk.
It has no value ... it doesn't work.

Comments about SM Pro Audio Q-AMP Enhanced 4-Channel Headphone Amp:

I bought this because it was a little cheaper than the Prosonus. They(2) were purchased September, 2010. I have had trouble with them ever since. The headphone jacks would not fit into the plugs correctly, I had to switch channels. The list could go on. In July, both of them gave out within a week of each other. I could understand one going out, but both within a week of each other?

Pleasently surprised...

Comments about SM Pro Audio Q-AMP Enhanced 4-Channel Headphone Amp:

So I finally did it, I bought a heaphone amp. After years of using splitters I decided it was time. I went with this one because my primary concern was dependability. No offense to the other brands, but they just have that look, like they're saying to me "you better buy a good warranty!" Now that I have this unit, I can confidently say its built like a tank. The build quality from the potentiometers, knobs, to the box itself are all top notch. There is a LOT of smooth resistance in the knobs, not flimsy, very accurate... I wish my interface had knobs/pots this nice. If you've dealt with this stuff you know exactly what I'm talking about. A loose and flimsy knob/pot can really make or break a piece of gear. I was a little slow to jump on the bandwagon, but I'm now a big SMpro fan. Especially for utility stuff like this. Bottom line, this needs a review. Its a good unit, buy with confidence. Very good quality components. The functionality is practically the same as the cheaper versions of it, but youre buying a unit that will last you years instead of months. I would also assume these components translate into a quieter signal. I gave the features a 4.0 because I'd like to see the option of having both A and B switched on any one channel at the same time. But I can make due. Final note, this thing looks a lot nicer in person than from this picture.
