FEATURES PANEL CONTROL
6
1. INPUT VOLUME CONTROL
The two input attenuator controls (located at the front panel) adjust gain for their respective amplifier
channels in all modes.
The main amplifiers have input sensitivities of 1.24dBm) and have output voltage gains as follows.
: 300Watts = 34.6Volts / 450Watts = 42.4Volts / 600Watts = 48.9Volts
The Mono Bridge & Dual mono can be controlled by channel "A"
2. SIGNAL L.E.D
This green LED lights when its channel produces an output signal of about 2.5Volts or more,
indicating that there is amplified signal present in the amplifier.
It is useful in determining whether a signal is reaching and being amplified by the power amplifier.
Note : if the signal reaching the power amplifier is 50-100mV, the LED will not be active. Also,
if the amplifier goes into protective mode, this LED will not active.
3. LIMIT LED
This is a Amber LED and this indicators operate when the signal reaching 1.24dBM) or more.
4. TEMP ERR
This indicator operate when the temperature rise to over 95
℃
at heat sink in the main amplifier.
5. PROTECT LED
This indicator operate when occur a problem, over load, over heating and DC Voltage.
6. POWER SWITCH
Pressing this switch to ON will supply the power to this unit.
7. SPEAKER JACK
Connect same Poles of s,-) as terminal of connection of Left, Right Speakers.
8. CH A,B INPUT JACK
Balance & Unbalance signal input of Ch A & B.
Can use XLR jack & COMBO jack (XLF, 1/4")
9. STEREO, MONO BRIDGE, DUAL MONO SWITCH
Slide switch to select stereo or dual mono.
* The CH "A" attenuator can be controlled a power amplifier A,B at the same time in case of Dual Mono.
10. FRAME
This switch is for grounding between circuit ground and chassis ground to avoid problems like
an electrical potential difference.
11. AC CORD
AC220V - 240V, 50/60HZ
* Check the plug type before connections.
12. CIRCUIT BREAKER
When occur a problem on this appliance, the fuse will be cut off power to prevent from a problem.
To replace, use standard fuse as specified on this appliance.
