Performance™ Series AV2 Audio/Video Processor

REAR L/R

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)

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

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)

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.

FULL, 40 to 120Hz, NONE

40 to 120Hz

0, 1, 2

15, 20, 30, 38Hz

SUB MODE

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.
