Set “Amp Assign” to “Preamplifier” if connecting all channels to the Pre-out connectors using an external amplifier. link
This stops operation of the internal power amplifier of this unit, reducing interference in the preamplifier created by the power amplifier.

You can use the “Connection” setting to disconnect the built-in power circuit of each channel individually and use just your favorite channel as the Preamplifier. link

The output signal for the PRE OUT connector of Height 1 and Height 2 vary depending on the combination of the Height/Ceiling/Dolby Atmos Enabled speakers that you are using. For the PRE OUT connector that connects each Height/Ceiling/Dolby Atmos Enabled speaker, refer to “Speaker Layout” - “Layout” or “Front Layout / Middle Layout / Rear Layout / TS/CH”link.
