Compression mode switching
SM5902AF
The SM5902AF guarantees correct operation if the mand, during normal operation. However, all other
compression mode is switched, using the 85H com- settings should remain unchanged while switching.
Attenuation
The SM5902AF supports attenuation level adjust-
ments in steps 1/4 of the minimum level for smooth
attenuation and soft muting.
16MDRAM
The SM5902AF can use with up to 16MDRAM.
(in case of SM5856A1F, up to 4M×2.)
So you can get a long shock-proof time.
Note that acceptable 16MDRAM is 2048-refresh
type only. (Can not use with 4096-refresh type.)
