80w 240w 460w Mixing Amplifier with 6 Zones for PA System Public
Address System
Main Features:
- Standard case design, 1U aluminum panel.
- Amplifier type: Class D power amplifier circuit design, low loss
with more than 90% amplification efficiency.
- Digital: higher digital circuit integration, stability and green
energy saving further significantly improved.
- Small size: The use of highly integrated digital chip instead of
the traditional transformer, smaller volume can be reduced to 1U
panel, lighter weight.
- Junction clarity: No traditional annular transformer produces
high-frequency oscillation and common mode noise, and prevents the
current noise brought by coupling, crosstalk and electromagnetic
radiation. Meanwhile, the digital circuit has strong
anti-interference.
- Professional noise gate control output signal, to ensure the
background music noise.
- Intelligent power management function, automatically enter the
standby state when there is no signal, standby power is less than
3W, ensure 7 x 24 hours uninterrupted work.
- A total volume adjustment knob, unified control of all lines and
microphone volume, two parameter equalization adjustment knob, used
to adjust the high and low to improve sound quality.
- Each route input volume, each microphone volume has an independent
adjustment knob to control the volume.
- With the switch to play MP3 function keys: including Bluetooth,
radio, USB/SD card playback, small screen display playback status.
- With MP3 player, can play U disk, SD card in the audio program, the
maximum support 32G.
- With FM radio function, can receive frequency 88-108MHz radio
programs.
- 6 audio source input, including 3 standard line input interface, 3
standard microphone input interface.
- 1 audio output, can be looped to the next power amplifier audio
input interface.
- MIC3 has the highest priority. It automatically murmurs when the
signal is input. The junction FET converts the priority to ensure
that the signal is not distorted during the murmurs.
- 6-way partition key switch and indicator. When the partition is
turned on, the partition indicator is on.
- 70V, 100V constant voltage output, 4-16Ω constant resistance
output, CH1-CH6 six-way partition constant voltage output.
- Working status real-time indicator, 5 signal indicators, 1
protection indicator, 1 distortion indicator, 1 power indicator.
- Line safety work area protection, to ensure the output load in
short circuit, overload and other bad environment work safely.
- Perfect temperature protection function, when the machine
temperature rises, the temperature servo circuit will accelerate
the fan, the fan working noise is low.
- Peak negative feedback protection, when the signal distortion,
impact, or line voltage serious overvoltage, can effectively
protect the power amplifier.
- The cross timbre compensation circuit is integrated to correct the
high frequency loss caused by the interline transformer, so that
the signal spectrum curve on the line voltage is straight and the
timbre is beautiful.
- High octave bass cutting circuit, the use of low cutting technology
with timbre compensation, in the case of no loss of sound quality
to remove the safety risk of ultra-low frequency components, to
ensure the safety of the booster system work.
