Description

The QSC sound amplifier is suitable for both professional touring musicians and DJs, etc. Provides high power despite relatively small dimensions. The quality of the materials used and the technologies used have long been proven in previous series. Some new components are also used to improve the performance of the amplifier. Improved heat dissipation, which made it possible to work longer under heavy loads without overheating the device. Convenient controls on the front panel allow you to easily adjust the operating parameters, indicators are provided for monitoring them.

FEATURES
-Amplifiers of the model range work in the AB+H class and provide low heat generation, which allows you to obtain long-term higher power at the impedance of the acoustic system up to 2 Ohms – stereo or 4 Ohms – mono (bridge mode)
-2U height for all models
-Power toroidal transformers providing large currents in loads up to 2 Ohms and low noise
-The cooling system ensures smooth operation of the fans, depending on
heating and equal heating of all output transistors due to parallel blowing
-Amplifiers work well on reactive load and against EMF
-Smooth rise of the output signal during power-on
-A delay in connecting the speakers
– Amplifiers are guaranteed to turn on at a network voltage of 150 volts
-Operating modes: stereo, parallel, bridge
-Cutting filters 30Hz, 50Hz (separate for each channel)
-Peak limiter (separate for each channel)
-The protection system provides

Protection against short circuits (short-circuit duration is any, current consumption from the network in
in short-circuit mode about 1 ampere)
Protection against static and infra-voltage at the output (sistor)
Overheating protection (blowing time before exiting the THERMAL mode is about 40 seconds)
Protection against channel imbalance in BRIDGE mode
Protection against non-musical HF (operates in the range of 20kHz to 80kHz, separated by
each channel), indirect, not in the sound reinforcement path
Protection against radio interference (more than 80kHz)
Protection against false supply of 380 Volts to the network
– The display system provides indication of modes
short circuit, at the moment of switching on indicates the state of the line (mode without
load, with load, short circuit)
Activation of the clip-limiter (provided Kg > 1%, regardless of the load resistance and
mains voltage)
The presence of a signal at the output
Activation of thermal
Short-circuit protection activation
Activation of protection against non-musical HF
