Specifications

FRONT PANEL CONTROLS
The glass front panel contains 7 single shaft rotary
controls and 1 dual shaft concentric control. At the
bottom of the glass there are 8 push buttons and an
ACCESS door for the CAMCORDER inputs and
HEADPHONE jack.
TONE CONTROLS
The TREBLE control can boost or cut the high
frequencies by as much as 12dB. It has 21 detent
positions. 10 for boost, 10 for cut and a center FLAT
or OFF position. It effects the LEFT FRONT, CENTER
and RIGHT FRONT channels.
The BASS control can boost or cut the low
frequencies by as much as i2dB. It has 21 detent
positions. 10 for boost, 10 for cut and a center FLAT
or OFF position. It effects the LEFT FRONT, CENTER,
RIGHT FRONT and SUBWOOFER channels.
When either the TREBLE or BASS control is placed
in the center FLAT or OFF position all tone control circuit
elements are removed from the signal path.
INPUT SELECTORS
Two input selector switches are provided. Each
switch has twelve positions. The RECORD switch
selects which program source is fed to the TAPE OUT
jacks and AREA B. The LISTEN switch selects the
program source that feeds the AREA A power amp and
speakers. This allows one to RECORD one program
source while LISTENING to another.
The input selections are PH/AUX, CD1, CD2, TUNER,
TAPE 1 and TAPE 2 for Audio. The Video inputs are
SAT, TV, LV, VCR1, VCR2 and V-AUX.
LOUDNESS
The LOUDNESS control, (small center knob), provides
frequency response contoured to compensate for the
behavior of the human ear at lower listening levels. At
the fully counterclockwise position, the loudness contour
is electrically flat. As the control is turned clockwise,
selected frequencies increase in the correct proportion
for proper listening at softer volume levels. The
frequency balance is not affected by changes in the
volume control settings. First adjust the volume for the
desired listening level. Then adjust the LOUDNESS
control for the preferred compensation. It effects the
LEFT FRONT, CENTER, RIGHT FRONT and SUBWOOFER
channels.
BALANCE
The BALANCE control, (large outer knob), adjusts
the volume of the channels relative to each other.
L, (left): Turning the control to the left accents the left
channel by reducing the volume of the right channel.
R, (right): Turning the control to the right accents the
right channel by reducing the volume in the left channel.
At the center detent position both channels are equal.
VOLUME CONTROL (Area "A)
A super precision volume control is required for
superior surround sound performance. Tracking over
its entire range must be almost perfect or the audio
image will shift. Therefore, McIntosh Engineers have
designed a volume control system that retains the
familiar VOLUME CONTROL KNOB but provides "state
of the art" performance. Tracking accuracy for all six
channels is within one quarter of a dB throughout most
of its range. It provides ± 12dB of trim to all six.
channels for accurate matching of amplifiers and
speakers. It has 256 steps for excellent resolution and
% of volume and the amount of trim are digitally
displayed on the front panel.
The volume control for area B is a 2 channel version
of area A without trim and display.
MODE SELECTOR
Five operating modes are provided, MONO STEREO,
HALL. CINEMA 1 (DOLBY PRO-LOGIC) and CINEMA 2
(THX). The CINEMA 1 and CINEMA 2 positions have
illuminated logos to indicate what surround processors
are in use. Since DOLBY PRO-LOGIC decoding is
necessary to generate the 4 channels for THX
processing the DOLBY logo remains ON in THX.
LEFT and RIGHT FRONT and SUBWOOFER outputs
are active in the MONO and STEREO modes.
LEFT and RIGHT FRONT, LEFT and RIGHT SUR-
ROUND, and SUBWOOFER outputs are active in the
HALL mode.
LEFT, CENTER and RIGHT FRONT, LEFT and RIGHT
SURROUND, and SUBWOOFER outputs are all active
in CINEMA 1 and CINEMA 2 modes.
CENTER FILL is provided in MONO, STEREO, and
HALL by placing the CENTER FILL switch on the rear
panel in the "ON" position.
DELAY SELECTOR
The delay selector provides variable surround delay.
