1. CH1~CH6 INPUT JACK (OPTION)
These are input terminals which is designed electrical balanced circuitry. Optionally, the type of terminals,
XLR female jack, phone jack, screw terminals and RCA jack are provided. And transformer balanced circ-
uitary is optional per buyer's order.
2. INPUT GAIN CONTROL
According to the input signal source, adjust adequately these gain controls not to exceed input sensitivity.
When the input level exceed the rated sensitivity, output signal of amplifier could be distorted and overloaded.
Gain adjusting range of these volumes are 44dB, and general position of the volume is as following.
MIC (Microphone) . . . . . . . . . . . . . . . . . . . . . . . . . . . .-50~-60dB
MIC ATT (Electric Guitar) . . . . . . . . . . . . . . . . . . .-30~-50dB
AUX (Deck, Tuner, etc.) . . . . . . . . . . . . . . . . . . . . -20~-30dB
3. EQ CONTROL
The equalizer section provides +12dB of control over high, mid and low ranges at the following fre-
quencies.
HIGH : 10K, +12dB
-
MID : 1K, +12dB

4. PHANTOM POWER SWITCH
This switch turns on/off the phantom power supply for all channels. Use this switch when you are using co-
ndenser microphones. When this switch is turned on, DC +24V will be supplied to pins 2 and 3 of each
INPUT jack.
If you do not need phantom power, be sure to leave this turned off.
* It is safe to connect balanced dynamic microphones or line level devices even if this switch is left on, but
connecting unbalanced devices or devices whose transformers are center-grounded will cause hum or m-
alfunctions.
5. PRIORITY SWITCH
