Bass and treble controls
The bass and treble controls are available as IR and serial commands only. There are three
commands for each control: up, down and flat. The 16 levels for each one range from 8 up to 8
down.
These controls are for room-specific equalization only. They are not intended to be adjusted by
the customer. They are normally set once by the system installer and then left at that setting for
that installation. These commands are not supported on the Bose
®
TA-1 IR remote control. You
must use either a Phillips Pronto remote control that has been programmed for use with the TA-1
or use serial data commands through an IBM compatible PC.
