CEC Control
The CEC Control Out 1-3 ports pass manufacturer CEC commands such as
Volume Up and Volume Down over HDMI cables to up to three soundbars.
CEC commands may not be compatible with all soundbar brands; refer to
soundbar manufacturers for correct commands, and test before deployment.
RS-232 Control
The RS-232 Control port connects via modular RS-232 to any compatible device.
RX is located on pin 3, TX on pin 6, and GND on pin 7. Use an Audio Authority
serial to System Bus adapter to connect devices such as a TS04 touch panel
for control.
12V DC Power
Connect 12V power adapter to Power Input. The power Bus Out may be used to
power more Audio Authority compatible devices within the power supply’s capacity
by using an 801-077 power extension cable. The Power LED is visible from the
side view.
Analog Audio
In an application with passive rear speakers, do the following:
• Speaker Outputs - Connect speaker wiring to speaker terminal blocks securely
observing proper polarity.
• Analog Audio Input (xed) - Connect a 3.5mm stereo cable to the Analog Audio
Input jack.
• Analog Gain Switch - The gain can be set to Low (1.5W), Med (3W), or High
(6W), to match the rear speaker volume with soundbar at max volume.
Digital Audio Input / Soundbar Outputs 1-3
Connect an optical cable from the audio source to the Digital Audio Input of the
1800. Connect an optical cable from each Digital Audio Output to the corresponding
soundbar’s optical input.
LEDs
Connect LEDs (not provided) to the corresponding output ports on the Model 1800.
Observe correct polarity when connecting to LED strips or bars (see specications
table below).
LED Output driven by power supply: 1 amp maximum.
