Description

This has to be one of the best value big grunty power amps on the market today, featuring a massive 1700W+1700W  at 2Ohm/STEREO this amp is just what you need for driving those big double 18" subs with ease. Also features built in crossover filters.

As with all Quest Engineering products it's not looks alone, the design emphasis is on good sonic performance and long life span under professional conditions.

QA series amplifiers are designed to work in the real world. Oversized multi speed fans and generous heat sinks will keep the out put stage cool even if the amplifier is installed in a dusty and poorly ventilated area. Service and maintenance is easy as the internal architecture is laid out for easy access by a qualified technician.

QA series amplifiers are manufactured to a standard accepted as desirable practice for a concert standard power amplifier. Heavy gauge welded steel chassis with vibration proof fittings and an emphasis on over engineering guarantees years of trouble free service in demanding environments.

Clean power is the secret to long speaker life. Despite the claimed good specs, many amplifiers will distort with both channels loaded and driven before they hit full output power. Even some expensive "brand" name amplifiers will do this when presented with multiple drivers at low impedance (inductive load). The dirty signal makes it sound loud, but it will reduce speaker life.

The QA amplifiers are designed to handle low impedance (2 ohms) and inductive loads and when driven to excessive level will "soft clip", but the best insurance is no clipping at all.

The switchable limiter system is controlled by a high speed VCA chip that will limit both PEAK and RMS power to prevent clipping of the output stage. It will not affect audio quality but it will help protect your speakers when all else fails. Some speaker systems utilise sensing controllers hard wired into the amplifier output. In this case consult the speaker manufacturer's recommendations as the amplifier limiter may interfere with the operation of the system controller. If so, you should leave the amp limiter switched out.
