The Crest PA 150 is a rugged, medium-power amplifier with features that make it stand alone in the industry. It's a rack-mountable unit which occupies only one rack space, and yet packs a 75 Watts RMS per channel punch into 4, 8, or 16 Ohms. It's selectable; a feature seldom found on the typical solid state amp. In bridge mode, this power amp delivers 150 Watts RMS into 8, 16, and 32 Ohms. (32 Ohms is the load impedance for a 150 Watt, 70 Volt distribution system). There's no fan in the PA 150 to make noise. Adequate cooling is provided by two massive heat sinks. Each channel is protected from excessive operating temperatures with a thermal/fault system that is automatic, and only activates under extreme conditions.

We used this for a client's personal stereo guitar rig / PA.He needed something small and wanted no fan noise because he plays Jazz in clubs where people actually shut up & listen... you know, not your typical American audience.Because he gets his preamp tones from a sansamp and all his effects from a TC rack-mounted unit, this fit the bill perfectly.In addition to his own guitar, he often has vocalists, flutists, violinists sit in, so superb sound quality was paramount. In combination with the QSC H828 speakers, which are ruler flat yet loud, he has got a beautiful system. BTW: there was nothing wrong with QSC amps for the sonic quality with this client. He just couldn't stand any fan noise, so the passive cooling on this model was our choice.So far, he has traveled through the US and Canada with this system to rave reviews. No problems at all, despite the passive cooling. The entire system fits in the trunk of his compact car, rolls in on a cart with a single trip. He sets it up in about five minutes, "pinks" the room and is ready to play in ten.The sound quality is closer to studio monitors than any small PA I've heard. The amp has not given him any trouble, even though he uses every bit of its power every night. I would definitely recommend this amp for anyone who needs a powerful but compact unit for a low-noise application: studios, churches, sanctuaries, or just the cleanest little PA with no fan noise you've ever heard. Although price was not an object for this client, we like the fact that it is so reasonably priced too. This kind of audiophile quality usually costs AT LEAST $200 more in this power range. This is a superb hi fidelity amp with REAL power in a small format. If that's what you need, I'll bet you'll love it. Although we are not a dealer for Crest, we still recommend them in certain situations. We also recommend Musician's Friend for things like this we can't get because they usually have everything in stock and have a great guarantee. None of our clients have ever had any problem with service or returns with MF.
