Number 1 monitor amp

Simon54, 10.11.2013
I decided to get a really top quality power amplifier for use with my bass guitar and also as an occasional monitor amplifier. For the latter purpose I bought some really cheap "sacrificial" speakers as in my experience the speakers get bashed up quite easily however if you care for an amp it can last forever. As it turns out I have almost exclusively used this amplifier for powering monitors over the last few years and occasionally for FOH use although it is slightly underpowered for this.

I have no complaints about this amp at all. I use it every week and have never had a problem. Once or twice I have run it in bridged mode (accessed through some dip switches on the back) however most of the time I run in stereo. The sound is always clear and the unit is reliable - precisely what one wants from a poweramp - no excitement! QSC also has a great reputation, and I always get an approving nod whenever other PA guys look at my amps!

Ludovic77, 17.11.2011
Amps of very good quality, good performance and excellent value for money. Small negative point, its weight; 23Kg now we do not have the butter, the money of the beurs and the smile of the creamer who goes with ...

In short I strongly recommend this amp for the sound of small surface (ours, 40sqm).
