C1 Upgraded Version Preamplifier Board Class A Parallel Tone Board Support Tuning/HiFi Lossless Modes
Features:
- C1 upgraded version supports tuning mode and HiFi lossless mode.
- 4 large capacitor, adopting class A stabilized voltage circuit.
- The power supply voltage is between dual 12-18V AC (or dual 15-26V DC), and the current requires 0.5A and above. If it is an independent transformer, it requires more than 15W of power.
- Tuning mode: with treble, mid-range, bass, three-stage adjustable, combined with your power amplifier speakers, tune up the effect you want, high frequency is delicate and transparent, and low frequency dives deeper.
- Straight-through amplification mode: it does not support adjusting the treble, mid-range and bass; only the volume can be adjusted, the concept of high fidelity, focusing on restoring the original sound, and feeling the most authentic sound .
- Mode switching method: Bass potentiometer, turn the switch to the left to turn on, switch to the direct amplification mode, turn the switch to the right to turn off and switch to the tuning mode, and adjust the bass at the same time.
- Ensure no low noise, no current sound.
Precaution:
- Due to the fact that the preamplifier circuit is extremely susceptible to interference, the preamplifier board must be installed in a metal chassis. The preamplifier board should be as far away from the transformer as possible because the transformer generates magnetic field interference, and the audio signal line needs to use audio specific shielding wire.
Package Included:
- 1 x Preamplifier Board
