Setup
3-11
REAR L/R
FULL, 40 to 120Hz, NONE
Allows the manual selection of a crossover point for the Main Zone
audio output connectors labeled REAR/Z2 L/R. Available selections
include NONE, FULL, 120Hz, 100Hz and 80Hz to 40Hz in 10Hz
increments.
•
Select FULL to send a full-range signal to the Rear L/R speakers.
Otherwise, select the crossover point closest to the –3dB
low-frequency rating of the Rear L/R speakers.
•
When the speaker setup does not include rear speakers, select
NONE to redirect rear channel signals to the Side L/R output
connectors. If the Side L/R parameter is also set to NONE, the
AV2 will redirect surround channel signals to the Front L/R
output connectors.
Note: When the Rear L/R parameter is set to NONE, Dolby Digital Pro
Logic® IIx modes and DTS-ES® decoding are not available.
SUB/LFE LPF (LOW-PASS FILTER)
40 to 120Hz
Identifies the crossover frequency setting below which sounds that
may be available from an LFE track are sent to the subwoofer.
Available selections are 120Hz, 100Hz and 80Hz to 40Hz in 10Hz
increments.
SUBWOOFERS
0, 1, 2
Selects the number of subwoofers in the system. Available selections
are 0, 1 or 2. The 0 selection is only available if the Front Left and
Right speakers are set to FULL.
SUB HPF (HIGH-PASS FILTER)
15, 20, 30, 38Hz
Identifies the crossover frequency setting above which sounds are
sent to the subwoofer. As a general rule of thumb, the larger the
subwoofer driver, the lower the frequency should be of the Sub HPF
parameter. The available selections are 15, 20, 30 and 38Hz.
SUB MODE
NORMAL, LFE+FL/FR, LFE ONLY
Selects options that are available to control bass redirection. Available
settings are NORMAL, LFE+FL/FR and LFE ONLY.
NORMAL is the default setting when Front L/R crossovers are set to
any value other than FULL, and it is not user-adjustable. In this mode,
all frequencies below the crossover point of any main speakers (Front,
Center, Side or Rear) are sent to the subwoofer. In addition, if the
incoming audio stream contains an LFE (.1) channel, all frequencies
in that channel that are below the SUB/LFE LPF crossover point are
also sent to the subwoofer(s).
When the Front L/R crossover is set to FULL, the user has the choice
of LFE+FL/FR or LFE ONLY.
The default setting, LFE+FL/FR, steers all Front L/R sounds below a
fixed crossover point of 80Hz to BOTH the subwoofer(s) and the
Front L/R speakers. In addition, it redirects all frequencies below the
crossover points of the Center, Side and Rear speakers to the
subwoofer(s). Finally, if the incoming audio stream contains an LFE
(.1) channel, all frequencies in that channel that are below the SUB/
LFE LPF crossover point are also sent to the subwoofer(s).
The LFE ONLY setting does not send any sound to the subwoofer(s)
other than the LFE (.1) channel, if available.
SPEAKER DISTANCES MENU
Selecting the MANUAL SETUP menu, SPEAKER DISTANCES option
opens the SPEAKER DISTANCES menu, which allows the user to
manually set the distances for each speaker. The adjustable range is
0.0 ft (0.0m) to 30.0 ft (9.00m) at 0.2 ft (0.06m) increments.
