The Story
Quest Engineering's QX Rackmount Series amplifiers offer superior Class D performance with multi channel options across various models.
Ideally suited for any installation requiring small to medium power amplification, the QX Rackmount Series offer real flexibility with auto load matching LoZ and HiZ (70V or 100V) and standby functionality.
The series features class leading energy efficiency when units are in standby, while mute option enables the amplifier to be activated within 1ms.
HP and LP filters available on any channel make for very quick and reliable installation.
The QX4300 offers Low impedance, 70 V or 100 V direct drive on all channels, while the QX4150 and QX4750 offer the ability to bridge channels to give 2 and 3 channel operation.
Features:
- Superior class D technology providing high performance power amplification.
- Auto Load Sensing: 4-16 Ohm, 70V - 100V Hi Z
- Energy star compliance, standby power saving mode available per channel (switchable)
- UMAC™ Class-D – full bandwidth PWM modulator with ultra-low distortion
- Dante™/AES67 inputs available via Dante expansion card
- Individual volume control, standby, 80Hz HPF, 100Hz LPF, Limiter
- Short circuit protection, DC protection, under voltage protection, temperature protection, overload protection, HF protection
- UREC™ universal mains switch mode power supply with Power Factor Correction (PFC) and integral standby converter
- Euroblock style amplifier I/O connectors
- High Dynamic range incorporating, DynamiQ Bass technology®
- Designed, Engineered, and Assembled in Australia
