SRS Sound Controller with SRS FOCUS, SRS Surround Sound
On-Chip Sound Controller
Description
The M62436FP is a soundstaging control IC that was developed primarily for car audio systems. It provides increased
flexibility in speaker placement and can also be used for home audio applications. (The M62436FP is particularly
effective when combined with SRS.)
Note: The FOCUS technology rights incorporated in the M62436FP are owned by SRS Labs, a U.S. Corporation and

... 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. ...

... M62436FP The Focus gain can be reduced by connecting resistors between pins 14 and 15 and between pins 25 and 26. This has the effect of improving the maximum input voltage (and the output noise voltage) characteristics. However, there is a limitation on the maximum input voltage (Vl = 0.6 Vrms) due to the SRS sound block gain 150 Hz. ...
