microphone at the listening position before running Auto Setup.

Run Auto Setup – Press OK (or Oon the remote) to start Auto Speaker Setup. The process will generate test tones from the speakers and will typically take less than two minutes. The test tone generator will cycle round each speaker twice.

Accept Setup – When Auto Speaker Setup has completed without errors you can choose to accept or reject the settings

<No: The settings are not stored in memory.

<Yes: All the speaker settings (speakers present, type, distance, level and crossover frequency) are stored in the relevant sections of the Setup Menu and overwrite any previous settings.

Auto Setup Progress – Gives a summary of what Auto Speaker Setup is doing as it progresses, starting with which speaker is being tested.

<Noise Level: Checking noise level relative to each speaker and subwoofer.

<Number of Speakers: Speaker configuration is detected including the number of surround speakers and whether a subwoofer and center speaker are connected.

<Speaker Distance: Accurately detects the appropriate distance of each speaker position as well as the subwoofer with respect to the microphone position.

<Speaker Level and Size: The crossover is set based on each channel’s signal handling capability and the subwoofer crossover is automatically set. The SPL (Sound Pressure Level) of each speaker is matched with respect to the microphone position.

<Calculating EQ: Data gathered from each of the speakers is being processed.

<Completed Error: A problem was detected with the speaker setup. See the descriptions for each of the individual speakers, below. Alternatively an invalid speaker configuration was detected.

If the above speakers are correctly detected as present in your speaker configuration, their size (Small or Large), distance from the listening position and trim level (dB) will be displayed. Note that size does not apply

to the subwoofer. Otherwise an error message will be displayed:

<Not Present: A speaker was not detected on this channel.

Crossover Freq. – The frequency at which Auto Speaker Setup determined is the best point to filter low frequency sounds away from Small speakers and into the subwoofer (or Large speakers if a subwoofer is not present).

NOTE

Auto calibration is possible only for a 7.1 or

5.1speaker configuration. For other speaker configurations such as a 2.1 (stereo + subwoofer) setup, you must complete setup manually by referring to the guidelines below for Speaker Configuration, Speaker Distance and Speaker Levels.

Spkr Types

Settings for the types of loudspeaker you have connected in your configuration. These settings are applied to all audio inputs and are stored in memory and recalled each time the unit is powered up.

Here you set the type of speakers that you have connected to your AVR400:

<Large: capable of full frequency range reproduction

<Small: not capable of full frequency range reproduction at the low frequency end

<None: speaker not present in your configuration

<Subwoofer: Set whether a subwoofer is present or not.

NOTE

It is not possible to set all speakers to Small unless there is a subwoofer in your speaker configuration. If you do not have a subwoofer, you will be forced to set your front speakers to Large.

Crossover Freq – This is the frequency at which loudspeakers set as Small start to redirect bass signals to the Subwoofer or Large speakers in your system. Small speakers redirect bass to the subwoofer, if present. The exception is the Centre speaker which, if Small, redirects its bass to front left/right provided that they themselves are Large. This is done to help keep Centre bass directly in front of the listening position.

MCH Sub Levels – This setting controls the subwoofer level from an externally decoded multi-channel source (BD-A, SACD, etc). Most BD players require a +10dB compensation on the subwoofer channel to maintain the correct balance with the main channels.

<+10dB: for normal BD players which output the analogue subwoofer channel at the low 0dBr level. Gain compensation of +10dB is added to the subwoofer channel of the MCH inPUT in the AVR400.

<0dB Normal: for BD players which output the analogue subwoofer channel at the correct +10dBr level. No subwoofer gain compensation is needed on the subwoofer channel of the MCH inPUT in the AVR400.

Use Channels 6+7 for – If your main zone speaker set up does not include Surround Back Left and Right speakers, you can choose to use the Surround Back amplifier channels to Bi-Amp the Front Left and Right pair, or as a stereo power amplifier for Zone 2.

Spkr Distance

Calibration settings for the distances between the loudspeakers and the listening position.

NOTE

Speakers that are not present in your configuration will be greyed out.

These settings are applied to all audio inputs and are stored in memory and recalled each time the unit is powered up.

Units – Select whether you wish to measure distances in imperial or metric units.

As described in “essential setup” on page E-32, measure the distance from each loudspeaker in your system to your ear in the main listening position and enter the values. This allows the AVR400 to calculate the correct relative delay for each loudspeaker.

Spkr Levels

Calibration settings for the test noise signal level through the loudspeakers and measured at the listening position.

NOTE

Speakers that are not present in your configuration will be greyed out.

These settings are applied to all audio inputs and are stored in memory and recalled each time the unit is powered up.

Use the B and C navigation buttons on the remote control to select the relevant speaker. Press Oto enable/disable the calibration noise and the D and E navigation buttons to adjust the noise level from each speaker.
