3. LINE OUT
Full frequency signal line out, and allows "HIGH", "MID" and "LOW" tone regulation resistance, to adjust and modify
this signal, using in parallel connecting several speaker.
2. LINE IN
Allow connection of a high level signal source (CD/DVD guitar etc.)
1. MIC
"XLR" Input and output sockets, electronically balanced. The input "MIC" socket allows connection of a low level
signal source (altive microphone)
4. GAIN
Regulates pre-amplification of the signal coming from the input "IN", ensuring perfect operation of the channel
circuits. For a well-balanced again adjustment, set the V olume to approx 3 4 clockwise, then adjust the gain ac-
cordingly.
5. HIGH/MID/LOW
3-band equalization to modify the sound tone. These controls are electronically post-gain and if boosted can clip
the channel, in this case adjust the gain control anticlockwise. When the potentiometers are set to "0" the tone
remain unchanged.
6. VOL
Volume potentiometer to control the channel signal level. Normally optimal channel circuit performance is achieved
with the knob positioned at approx. 3/4 clockwise and the gain control set to the desired level.
7. GND/LIFT
2-position selector for separating the signal source ground and the amplifier ground circuits.
ON: the signal ground is electrically disconnected from the amplifier ground circuit (the chassis). If hum is heard in
the loudspeakers, the ON position breaks the ground loop, often the cause of this interference.
OFF: the ground of the input signals is electrically connected to the amplifier ground circuit (the chassis).
USE GROUND LIFT ONLY WITH BALANCED SIGNALS.
8. CLIP (Automatic amplitude clipper)
Automatic amplitude "CLIP" LED; when the audio signal reaches the dangerous threshold for the transducers, this
circuit will automatically intervenes by reducing the amount of signal in order to protect the speaker, avoide losing
roue and despicking distortion as well; the activation of these protections is recognized via the "CUP" Leds Lighting
up.
11. PWR
LED signal to indicate the switching on of the system.
12. TONE
This control allows you to adjust the tone within 0 ~ 10.
13. POWER switch
Turns this apparatus on or off.
15. AC power socket
It is used to connect the power supply to the unit via enclosed power cord.
Caution: ensure the source voltage matches the voltage of product before turning on the unit.
14. FUSE holder
The fuse holder is for containing the fuse, which is a safety device that protects the AC supplies circuit of the unit.
Caution: if the fuse blew out, it should be replaced with the same type and specification, if the fuse continues to
blow out, please stop using and refer servicing to qualified personnel.
16. Voltage selection switch
This switch provides two voltage selections: 115V or 230V, please select the proper voltage depends on actual
application.
