Revel in Sonic Sound with the Crest Audio Pro 9200 Professional Power Amplifier

By Neil Bethtodd

If a professional power amplifier with incredible sonic integrity is what you're after, you should check out the Crest Audio Pro 9200 Professional Power Amplifier. It delivers the sonic integrity that is the hallmark of Crest.

It is hard to believe that an amplifier with so much professional power comes in a compact, 2U package and weighs less than twenty five pounds " and at a lower cost. The Crest Audio Pro 9200 comes with automatic clip limiting that is designed to protect connected drivers.

The 2100 Watts per channel will make it possible to really blast people out of a room. The specifications of the Pro 9200 are very similar to its predecessors, the amps in the Pro 200 series. All pro series amplifiers have a frequency response that is within 0, -3 dB from 10 to 100 kHz, with hum and noise greater than -110 dB, "A" weighted. The input impedance is 15 k Ohms, balanced.

The IGM impedence sensing modifies the gain automatically to accommodate which of the impedence outputs are connected. The beauty of IGM is its short circuit protection along with loads as low as 2 Ohms and efficient operation.

The Audio Pro 9200 has a range of special features such as high efficiency heat sinks that are tunnel cooled and DC fans with variable speed that is designed to extend the life of the amplifier by limiting the operating temperature. It doesnt take long to realize that this professional power amplifier can really crank up the volume with the latest generation of high speed, wide-band width output devices and a host of features, some that help to enhance Crests sonic integrity.

In the Pro 200 series the airs temperature is measured by automatic temperature sensing systems and it is then funneled to the front panel exhaust by rear mounted cooling fans, which, should temperatures exceed operating limits, will shut down one of the channels. When youre blasting out sound at that level, everything and everyone is can feel the effects of the by product of heat.

Input connections on the rear panel are via XLR and actively balanced. There are binding post and Speak on output connections per channel to connect to the loudspeaker. The input attenuators and combination AC power switch/circuit breaker are located on the front panel of the amplifier.

There are 5 LEDs for each channel on the front panel that indicate ACL, temperature and signal protect, DC protect, and Active. The rear panel mode switch is used to choose, stereo, bridged mono, or parallel mode. The gain select switch on the rear panel will determine the amps structure of x40 or x20. The Crest Audi Pro 9200 has very impressive professional power. You will definitely be able to blast the neighbors out of bed in the middle of the night. You will want to be careful though; it would be a shame to blow a speaker on a kit that runs about $2000. - 18758
