Detailed Information:

1) Control accuracy: more than 100 times higher than mechanical potentiometers, relays shunt resistance than the array has at least 10 times, accuracy <thousandth.
2) quality / distortion: because the BB's top product, almost no switching distortion, distortion of less than one ten thousandth.
3) Life: mechanical potentiometers wear, with a relay control with greater use of long time contact resistance.
This circuit is intelligent, the following does not start at 0 dB PGA2311U internal amplification, the internal resistor array only start to control the volume, the output can be connected after the other before the class, in which case it is equivalent to the volume potentiometer harmonic signal switching function, remote control to> 0dB when it automatically starts an internal super-amplifier CS3310 do pre-amplification, up to 31dB.

Use Description:
1) power 1 to 2 seconds the display lit, lights flashing indicates normal, flashes three times YUNAJING

2) Power reset at-46dB

3) lower right corner of the encoder: as the screw is to adjust the volume potentiometer can also be pressed like a contact switch, three-way input switch input signal: DVD, CD, DRE

4) the ability to remote control receiver within 10 meters.

Board Size: 102 × 55mm

CPU board Size: 102 × 38mm

Voltage: AC 6V-0-6V/1A (no more than 9V-0-9V)

If you find that you can display dark characters left trimmer potentiometer on it, if we find there the word shadow, trimmer potentiometer on the left to eliminate.
