McIntosh MX130

pensate for the behavior of the human ear at softer listening levels. At the fully counter-
clockwise detent position, the frequency response is perfectly flat and the loudness circuit
components are removed from the signal path. Turn the control clockwise to modify the fre-
quency response in the correct proportion required for softer listening levels. The compen-
sated frequency response is not affected by changes in the volume control settings. First
adjust the VOLUME Control for the desired listening level, then adjust the LOUDNESS Con-
trol to the setting you personally prefer.
The LOUDNESS Control affects the LEFT FRONT, CENTER. RIGHT FRONT SUBWOOFer
Unbalanced, LEFT and RIGHT Balanced outputs and the corresponding outputs on the 6
CHANNEL Connector. These are Area "A" Outputs. The LOUDNESS Control is effective in
all five modes of operation.
The VCR1, VCR2, TAPE 1, TAPE 2 and Area "B" Outputs are not affected by the LOUDNESS
Control.
NOTE: The flat frequency response setting of the LOUDNESS Control is at the FULLY
COUNTER CLOCKWISE position, not at the center or 12 o'clock position where the
BALANCE Control is neutral.
M. SYS CAL (SYStem CALibrate)
Allows the volume level of all six channels to be accurately set using the built-in MX130
noise generator. Calibration includes individual channel volume adjustment or trimming which
may be required due to room geometry or differences in amplifiers or speakers. The calibra-
tion can be done by automatic or manual switching of the noise generator to each channel,
depending on the setting of the MX130 rear panel SURROUND CALIBRATE switch. The chosen
level calibration settings are then retained in the Control Center memory.
Surround sound calibration is possible in the HALL, CINEMA 1 and CINEMA 2 Modes.
Normal listening levels and surround calibration volume levels can be set as you desire
for HALL or CINEMA 1 Modes. For CINEMA 2 or Home THX
®
Audio Mode, the re-
quirements are more specific. Refer to the manual section "MclNTOSH HOME
THEATER SURROUND SOUND VOLUME LEVEL CALIBRATION" for calibration pro-
cedures for both CINEMA 1 and CINEMA 2.
An LED lights above the SYS CAL pushbutton during calibration operation.
N. SURR LEVEL (SURRound LEVEL), UP ( ) or DOWN ( )
The UP ( ) or ( ) pushbuttons adjust the volume level match of all six channels as described
in the manual section "MclNTOSH HOME THEATER SURROUND SOUND VOLUME LEVEL
CALIBRATION."
O. SURR PROC (SURRound PROCessor)
Press the SURR PROC pushbutton if you wish to remove all signal processing functions
in HALL, CINEMA 1 or CINEMA 2 modes and return to normal STEREO mode. Press again
to restore signal processing.
An LED above the SURR PROC pushbutton turns on to indicate when signal processing
is active.
P. REC LOCK (RECord LOCK)
Press this pushbutton to turn off Area "B" and disable any remote Area "B" sensors or
keypads. This avoids the possibility of someone accidentally sending a control signal from
