HiFi 5-Segment Ultra-low Noise Audio Tuning Board Preamplifier BA3822 Equalizer +/-11dB Adjustment
Description:
- Using for ROHM dedicated chips, each frequency point has an adjustment effect of 11db, a distortion rate of 0.01%, and an ultra-low noise voltage of 3uVrms. The three major indicators instantly surpassed the LM4610 and its competitors. The adjustment effect is also immediately noticeable during use. The sound quality is transparent and warm, compared to ordinary tones, it can adjust up to five tones independently without interfering with each other, which is something that traditional two-segment tones cannot compare to. Traditional tuner generally only have two adjustable frequency points, 300Hz low-pass and 1KHz high pass, and cannot be finely divided. This five segments audio tuning board has 100Hz, 300Hz, 1kHz, 3kHz, and 10kHz that can be independently adjusted to make the sound more pleasant and smoother. Compared with multi frequency DSP frequency division, it adopts a pure analog adjustment method to reject digital effects and jet jitter.
- Unlike the MLCC and multi-layer ceramic capacitors used in ordinary tones, we all use thin film capacitors to avoid resonance harmonics caused by ceramic capacitors in audio, and achieve clear and transparent sound quality. Equipped with high-precision long semiconductor voltage regulator and high-frequency low impedance filtering capacitors for NIPPON CHEMI-CON and LELON, it provides pure voltage to improve signal-to-noise ratio. This makes the background very peaceful.
- 12V-30VDC or 9-21VAC power input and 0.1A current, which can be used in cars or at home. It is especially suitable for pure post amplifier without volume control. The total volume potentiometer is equipped with a power switch, which can be turned off and on by rotating.
