MT5.1 High Power 5.1 Channel Amplifier Board 6-Way Digital Power Amplifier Board DC 19-24V Powered
Description:
5.1 home theater power amplifier board features good effect and stable quality.
Power supply requirements: DC power supply 19-24V/10A, 24V is recommended. Compatible speaker: 3-4R is recommended for bass, 6-8R for others.
It can be used to assemble medium-power 5.1 power amp. Suitable for home audio-visual environment, car speaker modification. It boasts high power, low heat, good sound quality, small size, high efficiency and power saving. Through long-term verification and continuous improvement, it is stable and reliable. You can use it with confidence.
Features:
1. Independent 6-channel input, 6-channel output, pure power amplifier
2. Input high sensitivity, can be directly connected to computer sound card, decoder, DVD, high-definition player, and can also upgrade most of the AV power amplifier connection, no noise, easy to use
3. This power amplifier uses 4pcs TPA 3116 as the core, for Rubycon electrolysis for coupling, shielded inductors for low-pass filtering, and film capacitors
4. The switch is controlled by the circuit, there is no popping sound when it powered on, and the control switch can be externally connected, and there is an external LED indicator interface
5. All use pure copper, large hole terminal, convenient wiring, safe and reliable connection
6. Controlled STB standby, 0V standby mute, open-circuit power amplifier module works. Energy saving, no heat generation. Input signal: Input signal 1.4V, suitable for computer sound card, decoder, DVD. Output power: Maximum 50W*4 (main box and surround), maximum 100W*2 (center and bass). Note that the high-voltage input and output power cannot exceed the maximum value. The +24V input temperature rise is relatively high, so pay attention to ventilation and heat dissipation
Package Included:
- 1 x Set of Power Amplifier Board
Note:
- Preamp 6-way volume control, volume potentiometer and amplifier power supply are not included.
Attention:
1. Ways to reduce background noise:
A. When using a preamp board or amplifier board with a potentiometer, connect the metal shells of all potentiometers with copper wires and solder them to the ground of the signal input position;
B. Connect the power supply ground of the power amplifier board to the bottom shell of the chassis when installing the chassis;
C. The audio signal terminal input must use audio dedicated three-core shielded wire.
2. Users have certain risks in assembling power amplifiers, and they need to have certain basic electronic knowledge and hands-on ability. The principle must be clear before installation.
