Features
Six independent high-performance independent volumes on-chip (0 to 87 dB in 1 dB steps, -∞)
L/R ch: 6 inputs with muting and attenuation
Two-channel record output (one channel includes a mute switch)
Input gain control for FL, FR, C, SL, SR, and SW channels (0/3.6 dB)
Record-input gain control (+1/+3/+4.6/+6.6 dB)
Output gain control for SL, SR and C channels (0/+6 dB)
Output gain control for the SW channel (+6/+10 dB)
Output gain control for FL and FR channels (0/+2/+6.5/+10.5 dB) *1
Microphone-mix gain control (0/-2/+6.5/+10.5 dB) *1
On-chip bass-boost circuits for the FL and FR channels
Internal balanced outputs for the ADC
