BRT-1 Baud Rate Translator
The BRT-1 is used when your
Cinema Reference is set to run
at 19200 for control system rea-
sons, yet you also wish to con-
trol the unit via IR. The BRT-1
will upconvert a 1200 Baud IR
signal to 19200 Baud. It does
not down-convert a 19200 sig-
nal to 1200 and as such, will
only permit the Cinema Refer-
ence to receive commands. It
will not down-convert feedback
to IR. The BRT-1 is a passive
device that connects to an open
ADA Bus port on the ADA Bus
wire harness. It does not re-
quire any additional settings.

Baud Rate Setup
ADA provides two operating speeds (baud rates), either 1200 Baud or 19200 Baud. While 19200
Baud enables faster control and feedback, it will eliminate the ability to control the Cinema Reference
Mach II from being controlled via an infrared (unless you add a BRT-1 Baud Rate Translator to the
system). At 1200 Baud, a 40KHz IR carrier is capable of being attached to the Cinema Reference’s
Hex control strings, hence creating an IR command. This command can be learned into most learning
IR remote controls. However, these IR remote controls cannot capture or pass an IR signal with a
baud rate of 19200. The BRT-1 can be added to systems that need to operate at 19200 but it is
important to note that you can opt to run the Cinema Reference Mach II at 1200 baud without compro-
mising system features.
The Out of the Box default is 1200 Baud. To set the Cinema Reference Mach II’s Baud Rate:
1
Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and press
the Mode knob.
2
Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and press the
Mode knob.
3
Turn the Mode knob clockwise until the display’s second line reads NETWORK BAUD and
press the Mode knob.
4
Turn the Mode knob to select between 1200 MODE or 19.2K MODE. Press the Mode knob to
continue with other setups. To completely exit the setup menu, turn the Volume knob.
