SOUND VOLUME LEVEL CALIBRATION."
SUBWOOFER
Home THX Audio spediciations require a subwoofer to be used in a home theater system.
A subwoofer loudspeaker is designed to reproduce only the lowest audio frequencies, which
are essentially non directional. The MX130 meets this requirement by combining the Left,
Right and Center channel signals and feeding them through a filter that allows only the bass
frequencies of 80Hz and lower to be fed to the subwoofer outputs. The non directional sound
characteristics of a subwoofer allow it to be placed in a wide range of room locations.
A well designed subwoofer will reproduce the low frequency music and sound effects pre-
sent in today's action movie soundtracks with dramatic impact. Using a discretely placed
subwoofer also allows the optional use of slightly smaller front loudspeakers.
Detailed information on Home Theater loudspeaker setup is covered in the manual enclos-
ed with your Mclntosh HT Series Home Theater loudspeakers.

The MX130 can be remotely controlled. Most of the operating functions performed
at the front panel, also can be done by the MX130 Hand Held Remote Controller. The
following information refers only to the front panel. Another section of this manual
explains the functions and operation of the MX130 Hand Held Remote Controller.
The last page of this manual folds out to show drawings of the front and rear panels
of the MX130. This will help you in identifying and locating the front panel controls,
switches, pushbuttons and the rear panel connectors and switches. The letters and
numbers on the drawings refer to the information that follows.
A. BASS AND TREBLE
Provide 12dB boost and cut, with neutral flat response at the center detent position. The
Bass and Treble controls affect the LEFT and RIGHT Balanced Outputs, the LEFT FRONT,
CENTER, RIGHT FRONT and SUBWOOFer Unbalanced Outputs. These are all Area "A" Out-
puts. The corresponding channels of the 6 CHANNEL OUTPUT connector are also affected.
The VCR1, VCR2, TAPE1, TAPE2 and Area "B" Outputs are not affected by the Bass and
Treble controls.
B. RECORD
Selects any of the 12 program signals that will feed to the TAPE 1, TAPE 2, VCR1. VCR2
and Area "B" Outputs.
Area "B" must first be turned ON in Area "B", by a keypad or remote controller
transmitting to an Area "B" sensor, before the Area "B" outputs will operate. Each
time Area "B" is turned on, TUNER is automatically selected at a volume level 50dB
below maximum.
The audio signals for SATellite, TV, Laser Video, VCR1, VCR2 and V-AUX will have their cor-
responding Video signals switched simultaneously. The selected video RECORD signals will
appear at the MONitor B, VCR1 and VCR2 and VIDEO Outputs. This allows the selected pro-
gram signals to be fed to an external TV monitor, as well as to one or two VCR units for record-
ing purposes.
All audio or video tape recording must be setup manually in Area "A" before a
