B022 Stereo Preamplifier Preamp Active Speaker Headphone Preamp with 6.35mm and 3.5mm Interfaces
Description:
Do you have a playing device output source, such as TV audio, player, video game, mobile phone, tablet, computer, and record player? And the sound of the device is not loud enough.
Just a powerful stereo preamplifier can solve the problem.
1. Japanese 4580 chip for sound amplification, which improves the volume and reduces the background noise, and the dynamic range is large and will not produce popping sound.
The output gain after amplification is increased by 60DB on the basis of the original input signal source. Therefore, it is suitable for equipment with low sound of general output level signals.
3. Two sets of stereo input: 3.5mm and RCA inputs. Mixed input is supported.
4. Three groups of stereo output: the front panel has 3.5mm and 6.35mm headphone output ports, and the rear panel has one set of RCA outputs. Output of these 3 sets of interfaces is supported at the same time.
5. The output has 2 independent volume knobs: 1 volume knob for 3.5mm and 6.35mm output and 1 volume knob for RCA output.
6. Can drive 16Ω-600Ω headphones.
7. Powered by 220V to AC9V transformer, and the sound amplification is powerful.
