speaker configurations. You can select the size and presence of each
speaker, the distance of each speaker from your normal listening position,
and the level of each speaker in your system.
Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem
of deteriorating sound quality as volume is decreased by taking into account
human perception and room acoustics. Audyssey Dynamic EQ works in tandem with
Audyssey MultEQ to provide well-balanced sound for every listener at any volume
Audyssey Dynamic EQ Adjust: Audyssey Dynamic EQ is
referenced to the standard film mix level of 85dB SPL for -20 dBFS. Due, to the
lack of standard outside the film industry, the film reference level may not be
appropriate when listening to other material. Audyssey Dynamic EQ Adjust
provides three offsets from the film level reference (5dB, 10dB, or 15dB) that
can be selected when the mix level of the content is not within the standard.
Audyssey Dynamic Volume: Audyssey Dynamic Volume solves the
problem of large variations in volume level between television programs,
commercials, and between the soft and loud passages of movies. Audyssey Dynamic
EQ is integrated into Dynamic Volume so that as the playback volume is adjusted
automatically, the perceived bass response, tonal balance, surround impression,
and dialogue clarity remain the same. The amount of compression can be set to an
of the following three levels - Light, Medium, or High.
Acoustic EQ: The A/V receiver features 5 Acoustic Equalizer
modes to choose from.

9-band graphic equalizer (63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz,
16kHz) for each of the 7 channels.
- Off: The graphic equalizer is not use.
HT-EQ: The tonal balance of
a film soundtrack will be excessively bright and harsh when played back over
audio equipment in the home. This is because film soundtracks were designed to
be played back in large movie theater environments. Activating the receiver's
HT-EQ feature when watching a film made from movie theaters corrects this and
restores the correct tonal balance.
Surround Channel Level: The channel level can be
independently set for Multi-Channel Stereo, CSII and other modes. You can adjust
the Center level, Surround level and Surround Back level from -12 to +12 in 0.5
dB increments. The Subwoofer level can be adjusted from -18 to +12 in 0.5 dB
LFE Level: This function selects the output level of the LFE signal
included in the Dolby Digital signal or the DTS signal. You can select from 0 to
Night Mode: Useful at night or when loud noise is undesirable, this
mode compresses the dynamic range, making it easier to hear quieter audio
