6. AMP OUTPUT TERMINALS
These terminals are for connection of speaker lines to deliver power
output to speakers.
7. PROGRAM AUDIO INPUT TERMINALS
Audio input terminal of PROGRAM signal(for normal announcement) with
screw terminal.
Input level is 0dBu (0.775V) 60K balanced.
Please make external wire link as below in case of using amplifier in serial
connection.
This makes reduction of resonance sound inside to make a clear
sound when pushing high pass filter.
Set the switch FD-200 for use of FD-200.
Be sure to set switch Normal, not using FD-200.
Setting of switch is Normal position, When factory production.
This is for DC 24V output terminal to connect external relay power
source or operation of external equipments.
Do not exeed to use max current capability 500mA.
Be sure to check polarity +,- when connecting external equipment.

impedance of amplifier. Set same level output impedance
when serial connection for two amplifiers.
