5.1-CHANNEL AND 7.1-CHANNEL DIRECT INPUTS
There are four listening modes available for use with surround
sources such as DVD-Audio, SACD, HD-DVD or Blu-ray players. These
listening modes are for use when the AV2 8-channel direct inputs are
in use. We recommend you use these listening modes under the
following conditions:
•
5.1 BYPASS – Use this listening mode when the Surround Back
L/R inputs are NOT in use and the input source device has its
own internal bass management system. The incoming audio
stream passes from the source directly through to the volume
control without any analog-to-digital conversion. This mode
also mutes the unusued input jacks to prevent unwanted noise
from interfering with system performance.
•
5-CHANNEL – Use this listening mode when the Surround Back
L/R inputs are NOT in use and the input source device does
NOT have its own internal bass management system. In this
mode, the analog source is converted to digital so that it uses
the same bass management options for the direct input as used
for all other inputs. This mode also mutes the unusued input
jacks to prevent unwanted noise from interfering with system
performance.
•
7.1 BYPASS – Use this listening mode when the 8-channel direct
inputs are in use and the input source device has its own
internal bass management system. The incoming audio stream
passes from the source directly through to the volume control
without any analog-to-digital conversion.
•
7-CHANNEL – Use this listening mode when the 8-channel
direct inputs are in use and the input source device does NOT
have its own internal bass management system. In this mode,
the analog source is converted to digital so that it uses the same
bass management options for the direct input as used for all
other inputs.
DTS AND DOLBY STATUS DISPLAYS
The upper right-hand corner of the front panel two-line display may
indicate status information regarding the incoming source. If a
Dolby or DTS source is input and the AV2 is configured to a
surround system, the following status indicators may be displayed
to indicate the state of the incoming source:
•
ES-ON: Indicates when an encoded DTS signal, discrete or
matrix, is input to the surround back channels. “ON” indicates
that the condition exists, or is active; “OF” indicates that the
condition does not exist, or is off.
•
DS-ON: Indicates when the input signal is encoded with Dolby
Surround under the Dolby 2.0 standard. “ON” indicates that
the condition exists, or is active; “OF” indicates that the
condition does not exist, or is off.
•
EX-ON: Indicates when Dolby Surround EX is input with the
digital stream, if a surround channel (3/2 or 2/2) exists. “ON”
indicates that the condition exists, or is active; “OF” indicates
that the condition does not exist, or is off.
