1. ZONE SELECTOR / G1-4 ALL switch - Control switch with LED indicator.
(G1 ALL=GROUP-1, G2 ALL=GROUP-2, G3 ALL=GROUP-3, G4 ALL=GROUP-4 switches)
Each of "G1-4 ALL" switch handle to "ON" status relating to definite each group switch array.
It is not related to each of switch's on or off status when forced on status by specific
G1-4 ALL switch but return to preset status when release the specific G1-4 ALL switch.
2. ZONE SELECTOR / GROUP-1~4 channel switch - Control switch with LED indicator.
(GROUP-1 ~ GROUP-4 = x16, 16 channel selector switches per group)
Each channel switching circuit supports individual switching point between channel out
and combined "C" terminal and one to one correspondence of specific channel out
terminal block on rear panel.
: Please do not apply and switch any high voltage or high current.
All of the switching circuit nominal capacity is up to 48VDC/0.1A into resistive load.
: Please released(push-OFF) all of "ZONE SELECTOR" section switches, after use them.
If not, sometimes interrupted the PA system main program signal when those switches
are maintain "ON" position.

6. MIC / ON switch - Control switch with LED indicator.
This switch controls to attached gooseneck mic on or off.
The internal monitor speaker volume will be -20dB reduced to preventing self acoustical
feedback problem when activate this switch.
7. CHIME Level - CHIME signal output level control.
Please fixed level refer to bargraph LED VU(below than 0dB, when the chime signal
make peak value)or destination speakers chime SPL. 4-Notes chime sound is useful
for pre announcement. It is not necessary to make big sound volume.
8. LM and HM EQUALIZER - Low MId(500Hz) and High MId(5KHz)band equalizer.
The mid band equalizer can easily make clear sound against absorbing or reflecting
energy from sound field. Center flat point and +/-12dB adjustable peaking resonance
type equalizer.
9. MIC Gain Control - Mic headamp boost gain control
This potentiometer can cover level of entire microphone sensitivity.
The maximized boost gain is up to +60dB(CW), m10dB(CCW) that continually
controlled end to end point. Please make the boost gain of attached gooseneck
microphone refer to bargraph LED indicating status. Normally, can find ideal point of
boost gain b30dB and +50dB scale of mic gain potentiometer.
10. PHANTOM POWER SWITCH
This switch turns on/off the phantom power supply.
Use this switch when you are using condenser microphone.
When this switch is turned on, DC +18V will be supplied to pins 2 and 3 of
MIC input jack.
If you do not need phantom power supply for use dynamic microphone,
be sure to leave this turned off.
11. MIC input connector - XLR jack or 1/4" Phone jack acceptable.
Please find enclosed gooseneck microphone and properly couple with this connector.
Enclosed microphone that has uni directional acoustic axis characteristics should
made on axis and maintained adequate distance 50 to 100mm between mic head
assembly and mouth.
