How To Adjust For Loudspeaker Levels; Right Front; Right Surround; Back Surround - McIntosh MHT100 Owner's Manual

How to Adjust Speaker Levels
A properly setup Home Theater surround sound system
should have all Loudspeaker levels adjusted to the same
starting reference volume level in the Listening/Viewing
Area. The MHT100 includes a built-in test signal genera-
tor, which can have its output switched into each Loud-
speaker, either automatically or manually. The desired test
signal volume levels of each Loudspeaker can be deter-
mined, in the Listening/Viewing area, either by listening or
with a sound pressure meter. Level adjustments are made
in small steps (1/2 dB) by using the MHT100 Remote Con-
trol LEVEL Push-button. The level can be adjusted over a
plus or minus 15dB range.
Notes: Before adjusting the SPEAKER LEVELs, you FIRST
must have performed the SPEAKER SIZE and
SPEAKER TIME DELAY adjustments. The SPEAKER
LEVEL On-Screen Display will indicate NONE for any
channel(s) that have been switched off in the SPEAKER
SIZE Menu. A sound level pressure meter will greatly
aid in adjusting the Loudspeaker levels.
1. Press and hold the Front Panel SETUP Push-button ap-
proximately three seconds to enter the Setup Mode.
The word SETUP will appear on the MHT100 Front
Panel Display and the MAIN SYSTEM SETUP Menu
will appear on the Monitor/TV screen. Refer to figure
12 on page 25.
2. Using the Up or Down
select Speaker Level on the On-Screen Menu, followed
by the SELECT Push-button on the Remote Control.
Note: The very first time the SPEAKER LEVEL MENU is
accessed, the factory default settings will be
indicated.
3. Determine whether you wish to use the Automatic or
Manual Loudspeaker Level Switching Mode. For Au-
tomatic switching, proceed to Step 4. For manual
switching proceed to Step 10 on page 30.

4. Using the Up or Down
select number 1 (NOISE) from the Speaker Level On-
Screen Menu, followed by pressing the Left
Right directional push-buttons to active the Auto-
matic Loudspeaker Switching Mode. Refer to figure
18.
Note: The word OFF, located to the far right of the word
NOISE, will change to show which channel is active
for making a level change. A G Clef Symbol ( ) will
also appear to the right of the numerical value
instead of dB. The test signal will start cycling
continuously through all Loudspeakers in 3-second
intervals.

5. While in the Listening/Viewing area, note the volume
levels from each of the Loudspeakers as the test signal
switches. If you determine that the test signal volume
is louder or softer in any of the Loudspeakers, the lev-
els should be adjusted so you hear the same test signal
volume from all of the Loudspeakers.
Note: The Left Front Loudspeaker volume level can serve as
a reference.
6. As the test signal stops at each Loudspeaker, adjust the
volume of the test signal by pressing the LEVEL Up
or Down Push-button on the Remote Control. If an
adjustment is made on a Loudspeaker, there is an addi-
tional 3-second time interval before the system
switches to the next Loudspeaker. As a level is
changed, the on-screen display instantly indicates the
level change.
Note: If the level is increased or decreased, the display will
indicate numbers or minus numbers.
7. As the test signal switches to succeeding Loudspeak-
ers, repeat the level adjustment process until the test
signal volume levels of all the Loudspeakers are the
same, then select EXIT on the menu. The MAIN SYS-
TEM SETUP Menu will reappear on the Monitor/TV
screen.
Note: The Loudspeaker level cycling mode can be repeated
as often as necessary.
8. Continue next to the SUBWOOFER SETTINGS. If you
do not wish to perform SUBWOOFER SETTINGS
Adjustments at this time, then proceed to the next step.
