Feature Highlights
- High performance TI OPA2134 audio operational amplifier for preamp circuitry With low noise, low distortion and high conversion rate.
- NXP high efficiency Class D TFA9815T power amplifier with BTL output for low voltage and high current capability.
- Each of the two sound channels use a different carrier frequency (550KHz / 600KHz) to achieve high fidelity conversion and minimized mutual interference.
- "0" dead zone design and protection against overheating, over-current, over-voltage, undervoltage, including detection protection on power up.
- Differential input level combined with adjustable negative feedback circuit ensures low noise, low interference and low distortion
- On/off mute function
- Closed APLS potentiometer ensures low noise and good channel balance
- RCA and 3.5mm two audio input, for flexible connections
- Minimum output 4 ohm adaptive impedance
- Banana plug/terminal output
