When trying to decide what type of surround speakers to utilize, either dipole or directional
speakers, there is much discussion as to which will perform better with 5.1 digital source ma-
terial. Some suggest placing directional speakers in the back left and right corners. While this
will work, if you are also employing back-surround speakers in addition to left and right sur-
round speakers, you will most likely have a better sound field with dipole speakers placed at
the listening position slightly above head level. You can then opt for directional or dipole
speakers for the back-surround channels.

When employing back surround speakers, you will need to determine if you are using one or
two speakers. If the back wall of the theater is not very wide, you may opt to include a single
speaker in the middle. If the rear wall is wide, you can include two speakers evenly spaced
along the back wall. The Cinema Reference Mach II permits you to have two, one, or no back-
surround speakers (and if they are large or small).
The Cinema Reference Mach II’s Out of the Box speaker setup has all speakers set to SMALL, all
speakers are on including two back surround speakers, and the subwoofer ACTIVE. To alter any of
these features:
1
Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and then
press the Mode knob.
2
Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and then
press the Mode knob.
3
Turn the Mode knob clockwise one click so that the display’s second line reads STEP 1 SPKRS
and press the Mode knob.
4
Turn the Mode knob to the desired speaker group (FRONT, CENTER, SURR, BACK, SUB)
and then press the Mode knob. To return to the previous Pro Setup menu level, turn the
Mode knob clockwise until the display’s second line reads BACK TO MAIN and press the
Mode knob.
5
Turn the Mode knob to select LARGE, SMALL, or NONE (FRONT does not have a NONE
option, BACK has large and small options for one or two speakers) and press the Mode
knob.
6
Continue altering speaker size settings for all speaker groups. Note that the option for the
subwoofer is not large or small, but rather ACTIVE (if your system has a subwoofer or
INACTIVE if your system does not have a subwoofer).
7
To return to the Pro Setup menu options, the second line of the display needs to read either
SPEAKER or SPKER. Turn the Mode knob clockwise until the display reads BACK TO
MAIN and then press the Mode knob. To exit the setup mode completely, turn the Volume
knob.
At this time, the Cinema Reference Mach II is setup for your specific speaker system with respect to
the number of speakers and their size.
