Scaling
The AC-CX84-AUHD has a scaler built into every HDMI output.
In a 2K/4K mixed system you can scale specific outputs up or
down to match the connected display.
There are 4 scaler modes to choose from:
1. HD-4K (scales 1080p to 2160p) HDMI Only
2. 4K-HD (scales 2160p to 1080p) HDBaseT Only
3. AUTO (automatically detects the capabilities of the
connected display)
4. ICT (for use with HDB
ase
T)
Using the Scaling buttons on the front panel:
1. Press and hold the button of the desired OUTPUT. The output button will illuminate, indicating that
the switch is ready for you to select a scaler mode
2. Press desired scaler mode
3. Press the desired OUTPUT button again to confirm
Audio Extraction
The AC-CX84-AUHD can extract the audio signal which can then be sent to an AVR, amplifier, or surround
sound processor. This is ideal if the system calls for the audio from a source to be played through
something besides the TV’s internal speakers.
You can extract audio via either Toslink or analog 2ch. Analog is ideal for 2ch systems and distributed
audio systems, while Toslink is ideal for (up to 7ch) multi-channel audio systems. Extracted Audio Mode
has 2 options:
1. Bind to Output: Extracted audio switches with the video *NOTE - This is the factory default mode
2. Matrix Mode: Extracted audio can be routed however you’d like. There are commands to allow it to
function as a separate matrix.
By default, the audio is bound to the output. This means that the audio from the source will follow the
display that you are watching. You may however want to bind the audio to the input instead of the output.
One use case of this is if the end user wants to listen to music while watching TV.
To set up Audio Binding:
1. Press and hold the BYPASS button for 3 seconds
2. The UP and DOWN buttons will illuminate. Toggle between options using these buttons
3. Once you find the desired choice (“Bind to Input”, “Bind to Output”, or “Matrix”), quick press the
BYPASS button
*NOTE • The 2ch analog audio port only supports 2ch PCM. Be sure to set the audio output of the source to
2ch PCM
