EFFECT LEVEL sets the amount of crosstalk cancellation, and thus the

apparent front width. It is the most important user adjustment to Panorama,

 

 

 

 

 

 

 

 

and has been given its own button on the remote. When EFFECT LEVEL is

 

 

 

 

 

 

 

 

all the way down, Input Balance, LF Width and the rear outputs are still

 

 

 

 

 

 

 

 

active.

 

 

 

 

 

 

 

 

 

 

INPUT BALANCE compensates for the occasional source with audible

Input Balance

 

 

channel imbalance. It is especially important when using Panorama for

 

 

 

 

 

 

 

 

 

 

movies. If the movie sound tracks are unbalanced, the dialog will wander

 

 

 

 

 

 

 

 

 

 

away from the center; adjusting the Input Balance corrects for this.

 

 

 

 

 

 

 

 

 

 

LISTENER POS and SPEAKER ANGLE are determined using the calibra-

Listener Position/

 

 

tion procedure on page 10. The resulting value for Listener Position should

Speaker Angle

 

 

then be used for the Panorama sections of Ambience and Reverb.

 

 

 

 

 

 

 

 

 

 

LF WIDTH controls the amount of low-frequency spatial correction that is

LF Width

 

 

applied to the signal. A positive value of LF WIDTH means the difference

 

 

 

 

 

 

 

 

 

 

(left minus right channel) signal has additional energy below 500 Hz, while

 

 

 

 

 

 

 

 

 

 

the sum (left plus right) signal has correspondingly less. (Negative settings

 

 

 

 

 

 

 

 

 

 

can compensate for recordings with too much of this property.) LF WIDTH

 

 

 

 

 

 

 

 

 

 

can add needed spaciousness and warmth to classical recordings made with

 

 

 

 

 

 

 

 

 

 

coincident or near-coincident miking. (See Chapter 5: Theory and Design.)

 

 

 

 

 

 

 

 

REAR LEVEL adjusts the loudness of the signals sent to the rear channels.

REAR DELAY adjusts the amount of time between the appearance of a signal in the front channels and its emergence from the rear. Generally, the correct delay is about 16 milliseconds but the setting depends on speaker set-up and source material. In general, the delay should not be so great that the rear sound becomes identifiable as a distinct source.

Rear Delay

REAR ROLLOFF sets the frequency above which the rear-channel sound is

Rear Rolloff

attenuated. It should be high enough to give presence and airiness to the

 

rear sound but not so high as to place distracting instrumental overtones or

 

other sounds behind you. The appropriate setting will vary with program

 

material.

 

The use of the CALIBRATE mode is described in the setup instructions beginning on page 11.

The procedures for naming a new version of the program (SET PROGRAM NAME) and storing it in one of the User registers (MEMORIZE PROGRAM) are described on page 29.
