External Resistors
The midrange through high-range gain of the Focus circuit of the M62436FP can be specified using an externally
connected resistor.
The midrange through high-range gain is set by the resistance division value between the 0.22 µ[?] connected to pin 7
and REF. The M62436FP allows the user-specified gain to be set to high or low by switching the Focus position H/L
setting of pin 18. The recommended resistance value settings are listed below.
1. Focus Position “H” Setting
2. Focus Position “L” Setting
Recommended Setting Values
Notes 1. The left channel setting pins 7, 8, and 9 correspond to pins 32, 31, and 30.
The effect (full-range gain) of the Focus circuit of the M62436FP can be reduced using an externally connected resistor.
