PA-A series is consist of each 60W/120W/240W output models, and this mixing amplifier
can be applied to everywhere due to both usage High-Z(100V/70V) and Low-Z(4Ω/8Ω).
It provides not only MIC, LINE but also variety of audio inputs such as AUX, TEL IN and additional
functions such as tone control of BASS/TREBLE, and priority mode.
Especially, users can operate the device for announcement and broadcast easily via interacting
RM-05A which is exclusive remote microphone.


● High Efficiency Class-D Amplifier
  - High efficiency, low power consumption due to Class-D amplifier.
● Various Input Terminal
  - 3 MIC Inputs, 2 Line Inputs, 1 Stereo Line Input, TEL IN and EXT IN input
● Input / Output Monitoring
  - Built-in input signal display LED and output level display LED (7 Dots) per channel
● Tone Control
  - Depending on the frequency used, there are treble and bass controllers to adjust the tone to suit your surroundings and purpose. (At 100Hz and 10kHz,each adjustable ± 10dB)
● Speaker Selection Switch
  - Selective-zone / All-zone broadcast by 5 speaker selection switches and a switch for all.
● Priority Broadcast Function
  - Priority broadcasting function is adopted which can control other input signals by input signal of TEL IN and INPUT 1. (TEL IN >> INPUT 1 >> INPUT 2~6)
● User Friendly Features
  - Chime and Siren, EXT IN, MIX OUT
● Phantom Power Support
  - PHANTOM POWER support for high intensity condenser microphone (INPUT 1~3)
