Package Contents
Before installing this product, please check the packaging and make certain the following items are contained in the shipping carton:
- 1800 Soundbar Demonstrator
- 12V 3A DC power adapter
CEC ControlThe 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.
12V DC PowerConnect 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 AudioIn 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 (fixed) – 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 1-3Connect 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.
LEDsConnect LEDs (not provided) to the corresponding output ports on the Model 1800. Observe correct polarity when connecting to LED strips or bars (see specifications table below).
LED Output driven by power supply: 1 amp maximum.
