Description
Professional standard rack
mount radio power amplifier with pre-amplification, with high,
independent bass and overall volume adjustment control, microphone
mute priority function, with good short-circuit, overload,
overheating and other self-protection, warning lights flash,
optional fault detection module, short circuit fault detection,
signal output, scalable achieve standby power amplifier automatic
switching function. This product provides PA system for regional
power amplifier to meet in large, medium and
small
establishments
Functions:
1, Standard 2U high rack mount
panel, beautiful and practical, with a treble, bass, and line input
independent volume adjustment.
2, 2 line inputs, 3 MIC inputs,
2 emergency input, 1 channel audio line output.
3, With the highest priority
first microphone with mute knob, MIC1 automatic *2/*8V power supply
adapter, *-way emergency input line has two
priorities.
4, Using the front stage
amplification FET , conventional push-pull transformer circuit
transistor , delicate tone , pure, built-in two active high-pass
filter and a low pass filter, an automatic reduction of signal
clipping .
5, Has a complete line safety
assurance, plant protection warning function abnormal operation,
overloading, short circuit when the corresponding warning lamp
flashes tips.
6, Body temperature protection,
machine temperature, cooling fan automatically starts to achieve
high reliability.
7, Portable power button with
indicator display, four power indicator tips.
8, With two kinds of power
output, constant voltage output *0V, **0V, impedance output
***6Ω.
9, The device uses an embedded
computer technology and DSP audio processing technology design,
using high-speed industrial-grade chips, start-up time is less than
1 second.
