5.1 PAN:
Date printed: 03.09.03
The 5.1 PAN is a six-channel panner with left, center, right, left surround,
right surround, and low frequency effects (LFE) channels. In addition to
the same parameters found in LCRS mode, the 5.1 panner includes
left/right surround panning and a LFE feed. 5.1 PANning parameters are as
follows:
• PAGE 1 = MPAN: CENT (center percentage), LsRs (left 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.
LsRs: This parameter controls panning between the left and right surround chan-
nels. This control provides 1° steps from –30° (left surround) to +30°
(right surround). L30 indicates full left surround, 30R indicates full right
surround, and L00R 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.
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.
5.1: 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.
LFE: The SW key serves as an ON/OFF for the Low Frequency Effects channel.
The rotary encoder controls the LFE level over a mute to +10 dB range in
0.5 dB increments (–∞ dB to +10 dB).
PANA: An unique Pan-Around function is activated by the SW key and controlled
with the rotary encoder. This is a single-knob function that provides an
easy-to-use pan setting around all selected loudspeakers (depending on
format) in a circular fashion.
DIVM: This is the divergence mode selector. The divergence function can be ap-
plied to panning between all channels or the front channels only. The SW
key or rotary encoder selects between OFF, FRNT, and ALL.
DIVG: The divergence function is used to bleed portions of sound from the
panned output to the other speakers. For example, if the divergence is ac-
tive and set to 100%, the LCR control will act as a traditional L/R pan pot
(assuming there is no center channel contribution). Panning to full left will
