INSTALLATION & OPERATION GUIDE
SPEAKER PLACEMENT
�Careful consideration must be given to the speaker location to realize the full frequency range. Depending
on the model, cube units can be mounted on the ceiling (SC models) or walls of the room, therefore many
combonations are possible.
�The speakers should be separated by at least 6 to 8 feet for stereo operation. They should not be closer
than 2 feet to any adjacent surface (wall or ceiling.
�The cube brackets should be attached to a stud or mounted anchor with bolts for secure mounting.
NEVER MOUNT THE SPEAKERS TO SHEETROCK WITHOUT SOME TYPE OF ANCHOR.
�The MC2.5B unit is designed with a swivel joint between the 2 speakers. Each speaker can be aimed
individually. The unit also comes with a mounting bracket for attachment to a wall (SC models) or ceiling.
The bracket screws into the threaded socket on the bottom of the unit, and may be adjusted so that the
speakers point in the desired direction.
SPEAKER SET-UP AND CONNECTIONS
1. After you have determined the speaker locations using the guidelines above, turn off the receiver or
amplifier and unplug it from the power outlet.
2. Use 2-conductor 16-gauge speaker wire. Remove about 2 inches of the outside jacket from both ends of
the wire, then stip approximately 1/2 inch of the insulation from each conductor at the speaker end. Use the
recommended strip lenght as specified in the amplifier/receiver installation manual for the other end.
3. Proper connection of the speaker wire is very important to ensure full range sound. Most amplifiers and
speakers use red (for +) and black (for -) as the polarity markings. The red wire should be connected to the
red terminal and the black wire to the black terminal at the speakers and the reciever/amplifier.
4. Repeat these steps for connection of all speakers to the system.
5. The MC2.5B mini cube speaker may be connected 2 ways depending on the receiver/amplifier used with
the system. The major difference is the subwoofer connections. An amplifier with a subwoofer output
connection, usually an RCA type connector. A sheilded audio cable is required for this setup with a
Y-Adaptor connecting the audio cable to left and right “LINE INPUT” on the subwoofer. The other option
requires the front left and right speaker cables be routed from the amplifier through the subwoofer to the
speakers. The wires from the amplifer should be connected to the “HIGH LEVEL INPUT” and the cables
going to the speaker should be connected to the “HIGH LEVEL OUTPUT” on the subwoofer.
6. IMPORTANT! Make sure there are no loose strands of wire touching each other across the speaker or
amplifier terminals. This can create a short circuit and damage your electronics.
7. Plug your receiver/amplifier in, turn it on, and enjoy your new music system.
After carefully unpacking your speakers, the carton and the packing material should be saved for possible
use later. If any speaker appears to be damaged, DO NOT attempt to repair or to connect the unit to the
amplifier. Repack the speaker and notify your dealer or Pro Acoustics USA for replacement or repair.
PLEASE NOTE:
When mounting speakers from wall surfaces, additional tightening of the hex screw may be
required.
PLEASE NOTE:
When using another type of wire, such as a flat ribbon, you will need to determine how the wire
denotes one lead from the other. This usually takes the form of a rib or a color stripe in the
insulation.

INSTALLATION & OPERATION GUIDE CONT.
SETTING UP THE SYSTEM
�Use the settings on the receiver/amplifier; if a separate subwoofer is being added, the volume and
crossover frequency will need to be set.
�The system will require setting up the front, center, and rear speakers as recommended in your
amplifier/receiver instruction manual. The subwoofer provided with the system allows setting of the phase,
volume, crossover frequency, and an auto power control.
�The phase switch is set for the best bass sound. Switch between the 0 - 180 position until the bass is
loudest. In some applications, there may be noticeable difference, and in this case, leave the switch in the 0
position.
�The crossover frequency can be set between 40 and 180Hz. It is recommended that the control be set to
180Hz with the mini cube speakers.
�The volume control should be set to the desired bass level for the system.
�The power switch can be set to OFF-AUTO-ON. The OFF position disables the subwoofer completely. The
AUTO position puts the subwoofer in a standby mode (low power) when the system is not in use. When a
signal is supplied, the subwoofer is automatically turned on. The ON position is a constantly ready with or
without a music signal. The AUTO position is recommended for most applications.
