High Level Connections Continued

Using the MPS-150 with full frequency range speakers:

For systems where preventing bass signals from reaching your stereo speakers would be undesirable, connect TWO

SETS of speaker cables to the terminals of your receiver or amplifier. Run one set to the "HI LEVEL IN" terminals of

your MPS-150, and the second set directly to your stereo speakers. In this manner, you have by passed the MPS- l

50's "High Pass" crossover.

Connecting the Electronics and Subwoofer Modules

Using the cable supplied with your MPS-150, which terminates in a 1/4" phono plug at either end, install the plugs

into the corresponding jacks found on the Electronics and Subwoofer Modules.The right angle side attaches to the

sub. This cable allows the Electronics Module to supply power and signal to the Subwoofer Module. If a cable of

different length is needed, please contact your Authorized AGA Dealer.

Placement Of Your MPS-150

Given its small size and cylindrical shape, the sub module may easily be hidden from view. Finally a sub that

actually does fit under a piece of furniture. To obtain the best possible bass performance, however, please consider

the following placement rules.

Bass Output Varies With Placement.

Placing the MPS-150 near a wall (i.e., at the intersection of wall and floor) provides a doubling of output (+ 3dB)

compared with free space placement, while corner placement (the point where two adjacent walls and floor meet)

enables output to double again (+ 6 dB). In large or acoustically absorptive rooms, placing your MPS-150 near a

wall or corner might offer beneficial bass augmentation..

SIot-Loaded Woofer Design:

Your MPS-150 is a downward-firing or "slot-loaded" design whose output couples to the room through the narrow

space between the bottom of the woofer and the floor. Given the small size of this opening, it is important to keep

obstructions away from this space.

All Placements Are NOT Created Equal:

A subwoofer might sound noticeably different depending upon its location in the listening room. There will usually be

one spot at which any sub sounds its best. If possible, experiment with placement until the optimum position has

been determined.

Connecting your MPS-150

The following connection instructions will help you achieve the best subwoofer performance in your system.

Line Level Connections:

Connecting your MPS-150 to a home theater receiver .

In most cases you will be using these inputs. If you have a relatively new digital receiver it will have an "LFE" or

"subwoofer" output. Usually this is a single RCA type jack. Basically you will be running a cable that has RCA

connectors on both ends from this output on the receiver to the Line In jack on the sub. You can connect to either

right or left input on the sub with the same results.

Connecting your MPS-150 to a

preamplifier , stereo or Dolb y Pr o-Logic receiver .

Any component NOT equipped with a discrete "subwoofer output" jack or jacks: Essentially you will be using the

tape loop or pre-amp out jacks to send signal out of the receiver into the sub. Run interconnect from an output to

the LINE IN jacks on the sub's control panel. If necessary, run a line from the Line Out jacks back to the receiver.

WARNING:

LINE IN/ OUT jacks on the MPS-150 DO NOT include any crossover or signal filtering. When using

these connections in a system containing Nucleus Micro satellites or other bass-limited loudspeakers, you must

prevent low frequencies from reaching (and damaging) your satellites. Select the "small enclosure" option on your

surround processor or receiver's menu for each line running to a Micro or other limited low frequency (small)

satellite. If there is no such setting see High Level Connections to follow.

High Level Connections

High level inputs are used when the MPS-150 is included in a system where no line level (subwoofer) output

jacks are present. An entry-level receiver would be one example. (or where the inclusion of a "High Pass" filter is

necessary to prevent low frequencies from reaching the stereo speakers) In these cases the subwoofer must be

connected through the use of speaker cables. This will mostly be the case in 2 channel stereo applications.

Using the MPS-150 with Nucleus Micro or other small "satellite" speakers:

In cases where the lowest bass

frequencies would either damage the stereo speakers or inhibit sound quality, run speaker cable from the Main

(Front left and right) speaker terminals on the back of your amplifier or receiver to the "HI LEVEL IN" terminals on

the control panel of your sub's electronics module. Run a second set of cables from the MPS-150's "HI LEVEL

OUT"terminals to your stereo speakers.
