To increase the overall beauty of the machine, the machine is made of ultra-thick aluminum panels assembled, solid structure, safe and reliable.
2 Power switch
The opening of the device is achieved through this switch, through the relay delay output to the speaker system, so as not to hear the impact when the boot; current limiting circuit will weaken the peak when the start of the impact on the power grid and may burn insurance.
3 Power indicator
When the power switch is turned on, the indicator light should be on; if the lamp does not light, the power plug may not be connected to the mains supply or the fuse is burned.
Rear panel structure
1 Power supply
After setting the correct voltage, connect one end of the power cord to the machine outlet and the other end to the mains.
2 Insurance seat
Built with a fuse tube.
3 AC power output socket
The rear of the machine is equipped with AC power outlet for other equipment, but the total power of the device can not exceed 5A.
4 Signal input connector
Connect the signal source to the amplifier. The input signal connection of the amplifier is based on IEC268 using electronic balance. The two input connectors are connected in parallel.
5 Bass frequency adjustment potentiometer
Clockwise rotation allows the bass frequency to vary continuously from 30 Hz to 120 Hz.
6 Phase switch
Can be 0 degrees and 180 degrees can be selected (only for the bass SUB channel effect.)
7 Output dedicated terminal
This output is connected to the speaker input interface, pay attention to the polarity can not be reversed, but also to ensure that the power line size.
8 Fans
The fan reduces the temperature by accelerating the air flow inside the machine, and the machine's internal temperature determines the fan speed. Please have enough space around you.
Connection Note:
1. Turn off each attenuator before connecting.
2. When connecting the speaker cable, please do not turn the power output line back and forth, but can not make the positive and negative contact.
3. Make sure that the supply voltage meets the requirements of 220V~50 / 60HZ and then connect the power plug.
4. Each group of power output load impedance of not less than 4 ohms, resulting in damage to the power amplifier is not included in the scope of the three packs.
