2 in 8 out Pre-Amplifier Speaker Distributor Signal Booster
Product function introduction
1. The B981 is a powerful 8-channel high-power pre-amplifier which has dual-sound input with a selector switch.
2. The product provides an independent 3.5mm stereo earphone jack which can drive a variety of high-impedance professional monitor earphones well.
3. Each channel can drive 16ohm -600 ohm and provide 8 stereo channels for output.
4. There are four independent volume knob adjustments to control the 8-channel for simultaneous level signal output, presenting the rich sound quality, well-balanced bass, clear high frequency, and no other signal popping phenomenon, and ensuring lossless and undistributed sound.
5. It can provide +20dB high gain through any line level signal source, allowing running through lo-nger cable lines or "buffering" to solve low volume problems.
6. You can use the product to connect line level signal source and power amplifier as a volume controller.
7. The RCA socket can match almost all other product interfaces. The product is powered by an AC AC9V transformer.
