Features:

・Independent 6 channels for Master Volume (0 to -103dB, 1dB/Step, MUTE, BD3811K1)
    (0 to -95dB 1dB/Step, MUTE, BD3818KS)
    Implementation of a resistance ladder type circuit reduces residual noise and a
    shock sound at switching.
・Low current consumption design achieved by adopting the BiCMOS process
・Maximum output voltage (BD3818KS): 4.3Vrms (Vcc=7V, VEE=-7V, RL=10kohm)
    Maximum output voltage (BD3811K・: 4.2Vrms (Vcc=7V, VEE=-7V, RL=10kohm)
・Built-in Input Gain Amp useful for adjusting the output signal voltages
・Built-in Operational Amplifier useful for filter construction (BD3818KS)
・Built-in Dynamic Bass Boost circuit (BD3818KS)
・2-wire serial control (BD3818KS for 5V, BD3811K1 for both 3.3V and 5V)
・Built-in Output Gain Amp useful for adjusting the output signal voltages (BD3811K1)
・REC output terminal with a REC input/output switch useful for monitoring Equalizer Amp
    (BD3811K・
・Output mute controlled by either serial data or an external control terminal
