General Description

Built in stereo 4 input selectors and volume that there is not an impedance change of a volume terminal.

And this is sound processor can realize 2-band equalizer (bass/treble, gain±14dB / 2dB_step) and bass-boost, output-gain, surround by external components.

●

Key Features

  • Built in stereo 4 input selectors (single end).
  • Built-in input gain controller for volume of a portable audio input.
  • When the volume setting exchanging, it can use a volume input terminal as a microphone input terminal because there is not an impedance change of a volume input terminal.
  • Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for Bi-CMOS small scale regulator and heat in a set.
  • The pa.
