QSC here. DCA, ISA and MXa series. The bulk have been DCA amps though. Mark, watch out on the Crowns (CE, CL, CH series)...they do not ground their inputs (despite the symbol the silk-screen on the panel). Also, they have a quirk in that the SPI indicator is on the input, pre-attenuator. Steve ------------------ "Old projectionists never die, they just changeover!"

I haven't done that many installations (about 20 screens total). I had good experience with QSC 1400 (which is out of production now) and so I just kept using that model wherever possible. I was striving for uniformity from theatre to theatre in this chain I work for. Sometimes it wasn't possible to find that many used 1400s...One of the theatres (a 3-plex) uses the USA type by QSC. Another one (5-plex) uses Ashley amps. I think their subs are driven by Crown amps. I'm always on a budget, so I got nearly all of my amps used and they are in great condition. I only had to return one and that was because the rack was set up for 220V and the amp in question was 110V only (or vice-versa).

quote: Pete said: Middle of the road jobs I've been using HFA amplifiers made by a UK company called BK Electronics, and for the budget concious there's the OMP series from the same stable. Cheap they may be but they are surprisingly good for the £££
As I installed stereo for monitoring in the projection room and to be able to enjoy a film from the large viewing port, I used BK Electronics OMP amplifiers which you can also get in module form only. Well built and rated at 100 watts rms, also included in the same price is a very meaty Toroidal power supply for a mere UK £39 including UK VAT plus £10 to include loudspeaker protection. Excellent value and service with a very little price increase today. www.bkelec.com/ B.K Modules & Hybrids page. The main amps with the Dolby CP55 were Quad make.
