Speaker configuration and “Amp Assign” settings

This unit has a built-in 9-channel power amplifier. In addition to the basic 5.1-channel system, a variety of speaker systems can be configured by changing the “Amp Assign”link settings to suit the application, such as 7.1-channel systems, bi-amp connections and 2-channel systems for multi-zone playback.

Perform “Amp Assign” settings to suit the number of rooms and speaker configuration to be installed. link

Connection page

The sound mode that can be selected varies according to the speaker configuration. See “Relationship between sound modes and channel output” link for the sound modes that are supported.

The following pages provide basic connection examples.

Standard configuration and connection

5.1-channel playback

This serves as a basic 5.1-channel surround system.

7.1-channel playback (surround back)

This 7.1-channel surround system is the same as a basic 5.1-channel system but with surround back speakers.

Advanced connections

9.1-channel playback

This system, which is based on a 5.1-channel system, plays back up to 9.1-channels at the same time.

You can connect speakers for up to 11-channels for MAIN ZONE. When you connect speakers for 10 or more channels, the output speakers automatically switch according to the input signal and sound mode.

11.1-channel playback

This system, which is based on a 5.1-channel system, plays back up to 11.1-channels at the same time.

You can connect speakers for up to 13-channels for MAIN ZONE by using an external power amplifier. When you connect speakers for 12 or more channels, the output speakers automatically switch according to the input signal and sound mode.

7.1-channel playback (bi-amp connection of front speakers)

This system plays back 7.1-channels. You can use the bi-amp connection for front speakers. Bi-amp connection is a method to connect separate amplifiers to the tweeter terminal and woofer terminal of a speaker that supports bi-amplification. This connection enables back EMF (power returned without being output) from the woofer to flow into the tweeter without affecting the sound quality, producing a higher sound quality.

You can connect speakers for up to 9 channels for MAIN ZONE. When you connect speakers for 8 or more channels, the output speakers automatically switch according to the input signal and sound mode.

Exclusive 9.1-channel playback + 2-channel playback speakers

You can connect speakers used exclusively for 2-channel playback, which are used for the direct and stereo modes, and speakers used exclusively for 9.1 multi-channel playback. The speakers used exclusively for multi-channel playback and the speakers used exclusively for 2-channel playback are automatically switched for playback in accordance with the sound mode.

Exclusive 7.1-channel playback + 2-channel playback (bi-amp connection) speakers

You can connect speakers used exclusively for 2-channel playback, which are used for the direct and stereo modes, and speakers used exclusively for 7.1 multi-channel playback. You can use the bi-amp connection for the speakers exclusively used for 2-channel playback. The speakers used exclusively for multi-channel playback and the speakers used exclusively for 2-channel playback are automatically switched for playback in accordance with the sound mode.

7.1-channel playback + front speakers of second unit

This system enables switching playback between front speakers A and B as desired.

You can connect speakers for up to 9-channels for MAIN ZONE. When you connect speakers for 8 or more channels, the output speakers automatically switch according to the input signal and sound mode.

7.1-channel playback (MAIN ZONE) + 2-channel playback (ZONE2 or ZONE3)

This type of configuration plays back 7.1-channels in MAIN ZONE and 2-channels in ZONE2.
(Speakers can output audio from ZONE3 instead of ZONE2 (Assign Mode: 7.1ch + ZONE3)).

You can connect speakers for up to 9-channels for MAIN ZONE. When you connect speakers for 8 or more channels, the output speakers automatically switch according to the input signal and sound mode.

5.1-channel playback (bi-amp connection of front speakers: MAIN ZONE) + 2-channel playback (ZONE2)

This type of configuration plays back 5.1-channels in MAIN ZONE and 2-channels in ZONE2. You can use the bi-amp connection for front speakers in MAIN ZONE.

5.1-channel playback (MAIN ZONE) + 2-channel playback (ZONE2) + 2-channel playback (ZONE3)

This type of configuration plays back 5.1-channels in MAIN ZONE and 2-channels in ZONE2 and ZONE3.

7.1-channel playback (MAIN ZONE) + 1-channel playback (ZONE2) + 1-channel playback (ZONE3)

This type of configuration plays back 7.1-channels in MAIN ZONE and 1-channel (monaural) in ZONE2 and ZONE3.

You can connect speakers for up to 9-channels for MAIN ZONE. When you connect speakers for 8 or more channels, the output speakers automatically switch according to the input signal and sound mode.

Dolby Atmos

This speaker configuration is optimized for Dolby Atmos playback.

11.1-channel system

This system configuration plays back 11.1-channels by using an external power amplifier.

9.1-channel system

This configuration uses only this unit for Dolby Atmos playback.

Upgrade (Auro-3D)

Auro-3D

This speaker configuration is optimized for Auro-3D playback.

9.1/10.1-channel system

Top surround speaker is optional for Auro-3D. Connect an external amplifier to Subwoofer 2 pre out, to enjoy 10.1 channels of Auro-3D.

Connecting an external power amplifier

You can use this unit as a pre-amp by connecting an external power amplifier to the PRE OUT connectors. By adding a power amplifier to each channel, the realness of the sound can be further enhanced.

Select the terminal to use and connect the device.

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

When using just one surround back speaker, connect it to the left channel (L) terminal.

back to top

In addition to the connections described in link - link, this unit allows for various speaker connections with the “Amp Assign” setting.

Also refer to the menu screen in “View Terminal Config.” on the “Amp Assign” setting screen, which shows how to make connections in your environment.

When using a single surround back speaker, connect it to the SURROUND BACK L connector.

When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the speaker’s woofer and tweeter terminals.

When using front height and rear height speakers for Dolby Atmos playback, set “Assign Mode” to either “9.1ch” or “11.1ch”, and set “Height Speakers” to “4 Height Speakers”.

When using Dolby Atmos Enabled speakers for Dolby Atmos playback, set “Assign Mode” to either “9.1ch” or “11.1ch”, and set “Height Speakers” to “Using Dolby Speakers”.

For the best Auro-3D experience surround height speakers are recommended, however you may substitute rear height speakers from a Dolby Atmos speaker setup in place of surround height speakers.

When using the rear height speakers, set “Assign Mode” to “9.1ch” or “11.1ch”.
