1. SIGNAL OUTPUT and MONITOR INPUT/ 6p-Terminal block
Please pull out to backward of 6p-female terminal block before wiring.
Should refer to rear panel's printed subject of electric function and polarity.
The main signal flows out via the SIGNAL OUTPUT terminals that built by electronically
balanced circuits.
Should be open "-" terminal if connected with any unbalanced input.
MONITOR INPUT terminal for extra monitor input. (Electronic 10Kohm balanced input)
Typical monitor input level is -10dBm(245mV) for 1W monitoring sound power.
Please make wire bridge between terminal "G" and terminal "-" if connected
with unbalanced signal source.
2. ZONE SELECTOR OUTPUT Terminal block
Rated each mechanical contact switching circuit capacity is up to 48VDC/0.1A
(ERM-2320=125VAC/0.5A, 24VDC/1A max) that recommend control
to external relay circuits. Normally open, closing between selected specific zone switch
out and REMOTE COMMON out.
: Please used under the guarantee of rated switching capacity.
3. REMOTE COMMON Terminal block
This terminal is the reference of contact point of whole switching circuits.
4. 24V DC INPUT and FRAME GROUND Terminal block
Please find enclosed extra 24VDC power supply and plug in.
All of ERM series is prevented against over current cause the abnormal current flow
comming from switching circuits or internal circuit failure. It is automatically released
when resolving trouble.
Please make proper connection with earth for safety via the frame ground terminal.
