Name

Function

Negative Supply Voltage.

2

NON–INV. INP. CH. 1

Channel 1 Input Signal.

3

QUIESC. CURRENT

CONTR. CAP. CH1

This capacitor works as an integrator, to control the quiescent current to output

devices in no-signal conditions on channel 1.

4

SENSE (–) CH. 1

Negative voltage sense input for overload protection and for automatic quiescent

current control.

5

ST. BY / MUTE / PLAY

Three-functions Terminal.

6

CURRENT PROGRAM

High Impedance Power-stages Monitor.

7

SENSE (–) CH. 2

Negative Voltage Sense Input for Overload Protection and for Automatic

Quiescent Current Control.

8

QUIESC. CURRENT

CONTR. CAP. CH. 2

This capacitor works as an integrator, to control the quiescent current to output

devices in no-signal conditions on channel 2. If the voltage at its terminals drops

under 250 mV,

it also resets the device from high-impedance state of output

stages.

9

NON–INV. INP. CH. 2

Channel 2 Input Signals.

10

Negative Supply Voltage.

11

INVERT. INP. CH. 2

Feedback from Output (channel 2).

12

OUT (–) CH. 2

Out Signal to Lower Driver Transistor of Channel 2.

13

OUT (+) CH. 2

Out Signal to Higher Driver Transistor of Channel 2.

14

SENSE (+) CH. 2

Positive Voltage Sense Input for Overload Protection and for Automatic

Quiescent Current Control.

15

COMMON AC GROUND

AC Input Ground in MUTE Condition.

16

Positive Supply Voltage.

17

SENSE (+) CH. 1

Positive Voltage Sense Input for Overload Protection and for Automatic

Quiescent Current Control.

18

OUT (+) CH. 1

Out Signal to High Driver Transistor of Channel 1.

19

OUT (–) CH. 1

Out Signal to Low Driver Transistor of Channel 1.

20

INVERT. INP. CH. 1

Feedback from Output (channel 1).
