For Toshiba TA8184 Audio Tone Control Board HiFi Preamp Tone Board Support Electronic Volume Control
Description:
- TA8184P is a high-end tone specific chip for Toshiba, with a 12.5dB adjustment effect for both treble and bass, a distortion rate of 0.05%, and an ultra-low noise voltage of 4uVrms. The three major indicators instantly surpassed the LM4610 and its competitors. During use, the adjustment effect is also immediate, with transparent and warm sound quality, making the treble and bass balanced and more pleasant to listen to.
- The biggest feature of this preamp is the use of electronic volume control. It is known that ordinary potentiometers produce noise or impedance changes during rotation, resulting in sound distortion, reduced details, and susceptibility to interference. The grounding of the potentiometer casing is much important, and if not handled properly, the noise will greatly increase. Electronic volume control avoids this drawback by processing it internally. The potentiometer only provides a control voltage and does not undertake signal transmission tasks. So adjusting will not cause impedance changes and avoid interference. This makes the background peaceful and the details rich.
- Unlike the MLCC and multi-layer ceramic capacitors used in ordinary tones, we all use for Philips and Rubycon film capacitors to avoid resonance harmonics caused by ceramic capacitors in audio, resulting in clear and transparent sound quality. Equipped with high-precision 10V STM semiconductor voltage regulator, and external high-frequency low impedance filtering capacitors for NIPPON CHEMICON 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.
