Product Overview; Safety Precautions - Quest Engineering QX-300 User Manual

PRODUCT OVERVIEW

The QX-300 Amplifier is a compact, 2-channel, one third RU, high fidelity solution for both high (70/100V)
and low impedance (4 -16Ohm) distributed audio systems. The amplifier has automatic load sensing for
low impedance and 70V line operation and can output 100V in bridged mono mode.
The QX-300 can be used as a stand-alone amplifier, or with the available mounting accessories for
additional installation flexibility. Three units can be mounted in 1RU or 10 units can be mounted in 3RU.
For ease of operation the front panel features recessed volume controls and status indicator lights. A
removable magnetic cover doubling as an air intake filter hides Automatic Standby, Bridged Mono, 80Hz
High Pass Filter and Limiting selection switches. The Auto Standby function will mute the amplifier after 10
minutes of no audio signal presence and after 30 minutes the amp will enter a sleep mode, which allows
it to draw less than 0.5W (QX-300A) or 2.5W (QX-300D). Typical power-on from mute is <1ms and from
sleep mode is 660ms.
