10. LINE INPUT 5, 6 JACK
Connects with Line level device. Input Level is -20 dB (STEREO)
11. MIC, LINE INPUT 1~4.
INPUT 1~4: either microphone or line available. Individual power button for phantoms.
Input GAIN ranges -10dB ~ -50dB.
*XLR connector is needed to use phantom powered condense microphone.
(phantom power can’t be used by ¼” phone jack.)
* CAUTION!
In case phantom power is used, strong impulse noise might damage speakers.
It is recommended to minimize GAIN volume and master volume on front panel
before turning on phantom power.
Also, make sure phantom power is off before connecting/disconnecting microphone
and avoid strong impulse noise.

13. TELEPHONE
Connect INPUT terminal with trunk or telephone switcher LINE.
Connect LINK terminal with regular telephone and now it is ready to use.
When ring signal is sent to INPUT terminal, ring tone will release to the selected zone.
During ring signal INPUT, double check ZONE SELECTOR lamps.
This will help avoid malfunction and operate system properly.
You can adjust Ring signal volume by Chime Volume knob on front panel.
