This can be assembled with medium power 5.1 power amplifier, suitable for home audio-visual environment, car speaker modification, high power, good sound quality, small size, high efficiency and high power saving. Continuous improvement through long-term verification, stable and reliable quality, can be safely applied.
Feature:
1, Independent 6 input, 6 output, pure final amplifier
2, Input high sensitivity, you can directly connect to computer sound card, decoder, DVD, HD player, you can also upgrade most AV amplifiers, can be used with the power supply of the front panel, no noise, easy to use
3, This amplifier with 4 IC as the core (better than TPA3116), ruby electrolysis for coupling, large filter capacitor in parallel
4, All use pure copper, large hole terminal, convenient wiring, safe and reliable connection
Audio input:
Input high impedance, high sensitivity 100mv, adapt to computer sound card, decoder, DVD, car navigation and other 5.1 low voltage audio signal input
Output power:
Maximum 50W*4 (main box and surround), maximum 100W*2 (center and bass), please note that the input and output power with high voltage should not exceed the maximum value. +24V input temperature rise is relatively high, pay attention to ventilation and heat dissipation
Power supply : DC12-24V (can not be directly connected to AC)
Size (L*W*H): 100*80*30MM
Wiring instructions:
1. Before accessing the preamp, please do not plug or unplug the signal input cable when there is power to avoid damage to the chip.
2. Audio signal input socket white PH2.54/7P (6 + signal end, one signal ground).
3. Power input power positive +24V and power negative GND, can not reverse
4. Speaker terminal (6 channels are positive and negative, pay attention to the positive and negative of the speaker line, the positive and negative speaker lines can not be crossed in parallel)
Reduce background noise:
1. The front plate of the potentiometer or the copper wire of the power amplifier board is connected to the metal casing of all the potentiometers and welded to the ground of the front plate.
2. Connect the power cord of the power amplifier to the bottom box of the chassis when installing the chassis.
3. Audio signal input line must use audio dedicated three-core shielded cable
