Product Description

Product function introduction

The B981 is a powerful 8-channel high-power preamplifier which has dual-sound input with a selector switch.
The product provides an independent 3.5mm stereo earphone jack which can perfectly drive a variety of high-impedance professional monitor earphones.
Each channel can drive 16?-600? and provide 8 stereo channels for output.
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 undistorted sound.
It can provide +20dB high gain through any line level signal source, allowing running through longer cable lines or “buffering” to solve low volume problems.
You can use the product to connect line level signal source and power amplifier as a volume controller.
The RCA socket can match almost all other product interfaces. The product is powered by an AC AC9V transformer.
