result in full attenuation of the right channel. If the divergence is then set
to 50%, one half of the left channel signal strength will be bled into the
right channel (without effecting the left channel). With the divergence
control set to 1%, equal signal will be fed to both channels and the LCR
pan pot will have no effect. Divergence values are as follows: 1%, 2%,
3%, 4%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 60%,
70%, 80%, 90%, 100%. Careful use of this control may have the effect in-
creasing the size of the mix "sweet spot", particularly for large auditori-
ums. Misuse of this control may result in essentially mono panning.
Note: The order of 5.1 bus assignments is as follows: L, R, C, Ls, Rs, LFE.
The EX PAN is exactly the same as the 5.1 panner except it provides a
LCR mode for the surround channels. It has a seven-channel panner with
left, center, right, left surround, center surround, right surround, and low
frequency effects (LFE) channels. EX PANning parameters are as follows:
• PAGE 1 = MPAN: CENT (center percentage), sLCR (left surround/
center surround/right surround), F/S (front/surround), 5.1 (left/center/
right)
• PAGE 2 = FEED: FRMT (format), LFE (low frequency effects)
• PAGE 3 = MODE: PANA (Pan-Around), DIVM (divergence mode),
DIVG (divergence function)
CENT: A center percentage control is provided to adjust the amount of signal sent
directly to the center channel. This function has 5% increments and is acti-
vated using the SW key. When this parameter is inactive or set to 0%, the
LCR control acts as a traditional L/R pan pot with no signal being sent to
the center channel. This provides a phantom center channel image between
the left and right speakers. When CENT is active and set to 100%, signals
panned between the left and right channels are directed to the center chan-
nel. In this case, as the rotary encoder is moved from center towards the
left, the signal shifts from the center channel towards the left channel with
the right channel receiving no contribution, and vice versa.
sLCR: This parameter controls panning between the left, center, and right sur-
round channels. This control provides 1° steps from –30° (left surround) to
0° (center surround) to +30° (right surround). L30 indicates full left sur-
round, 30R indicates full right surround, and L00R indicates center sur-
round. The SW key allows the rotary encoder to be deactivated and there-
fore provides the ability to "lock" the pan position in place.
F/S: This front/surround parameter provides panning between front channels
(LCR) and the rear channels (left and right surround). This control oper-
ates within a range of 60 increments. F30 indicates full front, 30B indi-
cates full surround, and 0 indicates the mid position. The SW key allows
the rotary encoder to be deactivated and therefore provides the ability to
"lock" the pan position in place.
EX: This parameter controls the front left/center/right pan with 1° steps from
–30° (left) to C (center) to +30° (right). L30 indicates full left, 30R indi-
cates full right, and C indicates the center position. The contribution to the
center channel is determined by the CENT parameter. The SW key allows
the rotary encoder to be deactivated and therefore provides the ability to
"lock" the pan position in place.
FRMT: This serves as the format selector in all MPAN modes. The following se-
lections are possible: 2CH, LCR, LCRS, 5.1, EX, and 7.1.
