Overview
The QXD-10K is the flagship of Quest's QXD amplifier range: a 2RU, four channel Class-D amplifier with 10,000 W total peak output. Each channel delivers up to 1500 W at 8 ohm or on a 100V line, 2500 W peak at 4 ohm and 1200 W on 70V, so one unit can drive Qi Series tops and Qi18S subwoofers in a hard working venue.
The 32 bit, 96 kHz DSP includes FIR and IIR filters, peak and RMS limiters, delay and Quest's own speaker library, so you load the preset for the box and the protection is set from the start. Setup is from the front TFT display and encoder, with RJ45 and GPIO for system control. It suits live music rooms, large churches, auditoriums and performing arts centres.

Forefront Tip
Load the Quest preset for each speaker before you connect anything, and label each speakON output with the zone it feeds. In a rack, leave room for airflow front to back and set the fan curve to suit the space, especially in quiet rooms like churches and lecture theatres.
