FEATURES
VERSATILE AND CONVENIENT USE
13 channels of input signals from MIC 1-6, PHONO, CD, DECK, TUNER, AUX, CHIME, MIXER are
provided and mixed for versatile and convenient use.
MUTING FOR PRIORITY
Signal from Mic 1, 2, Chime, Mixer automatically activate the muting circuit which temporarily mutes
the signals from other input channels. You needn’t to reduce volume of other input channels. You needn’t
to reduce volume of other input signals when you make an emergency call or announcement by Mic 1, 2,
Chime and Mixer.
HIGH PERFORMANCE CIRCUIT
This pre amplifier employs the high performance circuit, and performs better than 65dB of S/N ratio and
less than 0.1% of THD.
USE OF EMERGENCY BATTERY
You can operate this pre amplifier by using of emergency battery for unexpected AC power failure.
INPUT SIGNAL INDICATING LED
This LED of volume control knob indicates input signal source
TRANSFORMER BALANCED CIRCUIT(OPTION)
Microphone input 6 channel and line output circuit are designed with electronic balanced circuit which
can use mic or line matching transformer optionally.
