Indestructible, reliable and quiet

By Adrien B, 08/02/2011
I use it for over 10 years! And this amp does NOT released or asked me a care ... Even outside in the pluis, hot weather, never any problems. Very efficient thermal protection, and the clip comes soon enough, the red LEDs indicate clearly visible in good time the risk of saturation. Always used with two speakers in 8ohms 300W RMS, offers a sound quite neutral and rather dynamic in this price range ... While it is heavy (large transformer ring antique and thick plate), but at the cost of solid reliability!
What I like most: its robustness and silent ventilation question
What I like least: its weight given the power output!
If it all over again: without hesitation ... I also just to separate myself ...

LoHerry's review

By LoHerry, 26/10/2004
Amp 2x425 watts into 4 ohms with all the protections that go ... Obviously it is in mono bridgable for a power of 800W into 4 ohms.

I have 10 years now, and I never had no problems with it!

The overall opinion is positive trs: quasiement his hi-fi, even low volume, no volumes with white noise background, color of its fairly neutral, trs good momentum.
The quality is always that of QSC: say anything, it's tough stuff. Ventilation trs silent and efficient (very rarely in high-speed).

The protections are the height (short juice, saturation, overheating). Personally, even if it is robust trs, I did not have fun throwing the money truck to test it ... Others are loaded it for me with their ... and the test is clear: rsiste treatment of turn!

It is not that it supports the same loads 2 ohms, o the quality of the circuits and the margin of tolrance ...

I use it with 3-way 400W speakers Montarbo / 103dBm, the record is good and trs trs prcis

The report qualitprix trs is good, it is ready for a life of artist ...

Exprience with this amp, let alone new MODELS, I would do without this choice hsitation!
