FV3 High Precision Passive Preamplifier Audio Volume Controller For Post-Amp Active Speakers (Standard Version)

Difference Between Standard Version and Advanced Version:
- Standard Version: It is a fundamental version for using ALPS16 high-precision potentiometer. Output and input RCA interfaces are made of pure copper gold-plated.
- Advanced Version: It is advanced for using ALPS27 large low-noise high-precision potentiometer. Output and input RCA interfaces are American 24K gold-plated CMC816 RCA.

Description:
At present, there are many audio sources, such as HiFi computer sound cards, DACs, CDs, players, etc., the output signals of these devices are relatively large, and some active speakers and pure post-amplifier have larger gains, so they cannot be used with active preamp to amplifying the signals. You can try our passive preamp. Thanks to no power transistor inside, coloration can be minimized.

Features:
- Aluminum alloy structure
- All imported electronic components for long service life
- Can be used with post-amplifiers and active speakers
- Designed without gain. If it inputs 1V, it will output up to 1V
- Can be applied to monitor your audio equipment, featuring lossless sound quality
- Perfect for HiFi devices
- Input Impedance: 50KΩ

Package Included:
- 1 x Active Preamp Volume Controller
