13
VIN1
Channel 1 input
14
VIN1G
Channel 1 input (gain adjustment input)
15
VIN2
Channel 2 input
16
VIN2G
Channel 2 input (gain adjustment input)
17
VIN3
Channel 3 input
18
VIN3G
Channel 3 input (gain adjustment input)
19
REG-IN
Regulator input (external pnp transistor base)
20
REG-OUT
Regulator output (external pnp transistor collector)
21
VREF-IN
Reference voltage input
22
VCC-S
Signal system power supply (This pin must be shorted to VCC1.)
23
VIN4G
Channel 4 input (gain adjustment input)
24
VIN4
Channel 4 input
25
MUTE
Channels 1 to 4 (BTL amplifiers) output on/off control
26
S-GND
Signal system ground
27
FWD
Channel 5 (VLO) output switching (FWD); loading block logic input
28
REV
Channel 5 (VLO) output switching (REV); loading block logic input
Note:
The center frame (FR) is used as the power system ground. Along with the signal system ground (S-GND), this level must be the lowest potential in
the system.
The three power supply pins VCC–S, VCC1, and VCC2 must be shorted together externally.
