5 – Level settings

The relative sensitivity of different speakers can lead to some speakers sounding disproportionately

loud or quiet, relative to others in the system. The level settings of your AVP700 can help to address

this in-balance.

It is important to calibrate the speakers correctly to achieve an accurately centred sound stage. If

possible, we recommend you use a sound pressure level meter (SPL meter) to perform this part of

the set-up as it is dif cult to judge the levels accurately by ear alone.

Test Tone Cycle

MANUAL is best for setting up with a SPL meter as the test tone will not change to the next

speaker until instructed by you. Pink noise is emitted by the highlighted speaker; when you

wish to measure a different speaker, move the highlight to the new speaker.

AUTO is best for setting up by ear. In this state, the test tone changes automatically between

speakers after a two second burst of sound.

On  rst installation, watch the OSD display as you cycle through the available speakers with the test

tone. Check that the speaker generating the sound corresponds to that indicated on the OSD. If there is a

discrepancy then check and correct the system cabling before proceeding further.

To calibrate the speakers with a SPL meter, place the meter at ear level with the microphone pointing towards

the ceiling, when seated in the usual listening position. (You will need to set the meter to ‘C’‚ setting with a

‘slow’‚ response and to read 75dB SPL at the centre of the scale.) If you do not have a SPL meter, simply set

the front left speaker to 0dB on the menu and then match all the other speakers to this level.

Each speaker can be  ne-tuned by 1dB increments to ±10dB. The output from each speaker needs to be

adjusted to the 75dB SPL sound level. No adjustments can be made for a speaker that is not selected in the

previous ‘Speaker Sizes’ menu. Note that inserting headphones into the front panel of the AVP700 will cause

all test-tones to be muted (including the headphone output).

6 – EX Settings

Surr. EX: This can either be set to AUTO or MANUAL and is applicable only when playing ‘Surround EX’-

encoded material.

AUTO DD EX: The AVP700 will switch automatically to ‘Surround EX’ decoding when suitably

encoded material is detected (this can be temporarily overridden by pressing the MODE

button on the remote control).

AUTO PLIIX MOVIE: The AVP700 will switch automatically to ‘Pro Logic IIx Movie’ decoding

when suitably encoded material is detected (this can be temporarily overridden by pressing

the MODE button on the remote control).

MANUAL: The AVP700 will not select Surround EX automatically. It can however be selected

manually by pressing the MODE button.

Use Channels 6+7 for

Choose one from:

DOLBY SURR EX: ‘Dolby Surround EX’ provides two additional rear channels from 5.1 channel

EX-encoded material. This is intended to give better effects steering. In this mode, ampli er channels

6 and 7 are used to drive the EX speakers.

ZONE 2: In this mode, ampli er channels 6 and 7 are used to provide speaker level output for use in

Zone 2.

BIAMP L+R: The ampli er channel 6 and 7 are used to provide a second ampli ed output of the

left and right channels. This allows you to bi-amplify your front speakers, which should give an

improvement in the sound quality of these channels.

If you would like to do this, please refer to page 26 for further information.

If you are using a 6.1

speaker con guration

(a single surround back

speaker), we recommend

connecting the surround

back speaker to the

surround back left channel

of the AVP700.

In this case, the level of

the connected surround

back channel should be

increased by 3dB (i.e., the

SPL meter should show a

response of 78dB for this

channel).
