NAME FUNCTION
1 43 CBIAS
Bypass Capacitor Connection Point to Internally Generated Bias. Bypass CBIAS with a 50µF
capacitor to system analog ground.
2 44 V SS Negative Power-Supply Input. Bypass with a 0.1µF capacitor to system analog ground.
3 45 L1_H
Left-Channel 1 High Terminal Input. Connect the source between L1_H and L1_L for differential
signals. Connect the source to L1_H and tie L1_L to BIAS for single-ended signals.
4 46 L1_L
Left-Channel 1 Low Terminal Input. Connect the source between L1_H and L1_L for differential
signals. Connect L1_L to BIAS for single-ended signals.
5 47 L2_L
Left-Channel 2 Low Terminal Input. Connect the source between L2_H and L2_L for differential
signals. Connect L2_L to BIAS for single-ended signals.
6 48 L2_H
Left-Channel 2 High Terminal Input. Connect the source between L2_H and L2_L for differential
signals. Connect the source to L2_H and tie L2_L to BIAS for single-ended signals.
7 1 LMR
Left Minus Right Output Signal. LMR output provides a signal that is the difference of left and right
input signals. See the Ambience Control section for more details.
8 2 AMBLI
Ambience Left-Channel Input. AMBLI provides the proper ambient effect at LOUT based on the
transfer function implemented between LMR and AMBLI. See the Ambience Control section for
more details.
9 3 CTL1
Left-Channel Treble Tone Control Capacitor Terminal 1. Connect a capacitor between CTL1 and
CTL2 to set the treble cutoff frequency. See the Tone Control section for more details.
10 4 CTL2
Left-Channel Treble Tone Control Capacitor Terminal 2. Connect a capacitor between CTL2 and
CTL1 to set the treble cutoff frequency. See the Tone Control section for more details.
11 5 CBL1
Left-Channel Bass Tone Control Capacitor Terminal 1. Connect a capacitor between CBL1 and
CBL2 to set the bass cutoff frequency. See the Tone Control section for more details.
12 6 CBL2
Left-Channel Bass Tone Control Capacitor Terminal 2. Connect a capacitor between CBL2 and
CBL1 to set the bass cutoff frequency. See the Tone Control section for more details.
13 7 LOUT Left-Channel Output
14 8 CLSN
Subwoofer Left-Channel Highpass Filter Capacitor Negative Terminal. Connect a capacitor
between CLSN and CLSP to set the highpass cutoff frequency at SUBOUT. See the Subwoofer
Ouput section for more details.
15 9 CLSP
Subwoofer Left-Channel Highpass Filter Capacitor Positive Terminal. Connect a capacitor between
CLSP and CLSN to set the highpass filter cutoff frequency at SUBOUT. See the Subwoofer Ouput
section for more details.
16 10 SUBOUT
Subwoofer Output. Connect a capacitor from SUBOUT to CSUB to set the lowpass filter cutoff
frequency at SUBOUT. See the Subwoofer Ouput section for more details.
