SP MK II FRONT PANEL DISPLAY
T
he display system used on the SP MK II uses a combination of light emitting diodes
(LED) and liquid crystal (LCD).
PRIMARY FUNCTIONS:
Surround operating modes, volume settings, time delay set-
tings, and panorama settings, are displayed on the liquid crystal panel. The selected
surround operating mode is always displayed. Changes in volume (front or back chan-
nels), time delay settings, and panorama settings, are momentarily displayed (about
ten seconds) on the second line of the liquid crystal display.
INPUT LEVEL:
The input gain control on the front panel is adjusted to illuminate the
Input Calibrate display to 0 dB. Then, the channel output trim controls on the back of
the SP MK II are individually adjusted to achieve proper output levels with sufficient
headroom and freedom from amplifier or speaker overload.
OUTPUT VOLUME:
Volume settings have a range from –85 to +15. These settings do
not necessarily relate to dB equivalents. Normally, the output volume level is set to the
0 REF setting when playing reference “0 dB” level signals from videodiscs and VHS
HI-FI video cassettes.
AUDIO SIGNAL DELAY:
Delay settings can be adjusted from 15 to 30 ms in the Pro
Logic or THX Cinema modes, up to 50 ms in 35 mm and 70 mm movie surround
modes, and up to 80 ms in some music modes. Changes in audio signal delay set-
tings are automatically retained in the memory of the SP MK II.
PANORAMA:
Panorama settings may be adjusted from –50 to +50 and will vary to
taste depending on the individual recording. Panorama cannot be engaged in the Pro
Logic or THX Cinema modes. Panorama settings cannot be stored because they are
also program source dependent.
SECONDARY FUNCTIONS:
Which include: Center Channel On or Off, Sibilant and
Re-Equalization (Re-Eq) Filters, Mute, Source, Record Select, and Center Boost, are
displayed by LEDs behind the front panel window. The status of functions including
Center Front On/Off, Noise Sequencer, Input Balance, are displayed by LEDs directly
above the button which turns the function on or off.
The Re-Eq and Center Channel On functions may be selected in all music modes.
Center channel is Off when Hall 1 or Hall 2 surround modes are selected but it can be
engaged, if desired. Re-Eq is only selected automatically in the THX Cinema mode but
it may be disengaged in the THX Cinema mode or engaged in other modes. Because
the need of Re-Eq in non-THX modes is program source dependent, it cannot be
stored in other modes.
