Standby section
Depending on the state of the logic inputs SBY1 and SBY2, RX2 and the Audio Buffer 2 can
be disabled separately. The TSH511 receiver can adapt to different applications by using the
SBY1 & SBY2 standby pins.
Table 6.
In the standard stereo mode, the configuration is: SBY1 = SBY2 = Low.
In mono mode with one load (example: a single load speaker), RX2 and Audio Buffer 2 are
disabled, the configuration is SBY1 = SBY2 = High.
In mono mode with a stereo load (for example: a stereo headphone), the configuration is
SBY1 = High, SBY2 = Low.
A pin is in High state if connected to V
