MK Sound MPS-1611P Speaker User Manual


 
6
triangle between the two speakers (Y & Z) and your listening position (X) provides the best placement solution. This means that
the distance between you and each speaker and the distance between the two speakers should be equal. Or, if the distance
between you and one of the speakers is 6 feet, make the distance between the two speakers 6 feet and the distance between
you and the other speaker 6 feet as well. See Figure 1.
Angle the speakers towards you until you can see the green LED at its brightest. This will insure that the woofer and tweet-
er are pointed directly at your ears.
If you set up your system and you feel that you don’t have phantom center clarity, your speakers may be too far away - try
moving the speakers closer together until they center channel image is restored.
D. Vertical orientation
The MPS-1611P is designed to be oriented vertically. This orientation provides the best image and phase-coherency. for
this reason, the bracket mounting holes are located on the bottom of the cabinet.
Horizontal orientation can be used, if your installation requires this.
MULTICHANNEL SPEAKER PLACEMENT
There is considerable debate within the professional audio community as to the best speaker placement for multichannel
mixing. Some mixers use placement solutions that are understood and well accepted, while others remain unconvinced about
a speaker placement standard and prefer to try other options.
One of the biggest obstacles to accurate monitoring in the control room is the recording console. With its large, flat
surface and its placement in the middle of the room, it provides the largest reflective surface between you and your speakers.
Reflected sound coming off the console arrives later than direct sound. The combination of direct and reflected sound creates
distortion in the form of comb-filtering. For this reason, we recommend that you do not place your speakers on the console
itself, but rather on stands around the console or wall-mounted on brackets above the console. M&K manufactures a full line
of stands and brackets which are designed to solve practically any installation problem. Check with your M&K dealer or log onto
the M&K Professional website, www
.mkprofessional.com for details.
In a multi-channel listening environment, all speakers should be of the same model and placed equidistant from the
listener. This is to maintain coincidental arrival of all channels at the listening position. If the center channel must be a smaller
speaker, we recommend using the MPS-1520 center channel speaker. It’s timbre is matched to that of our other main monitors.
When the MPS-1611P is used as a front loudspeaker it should be located with the tweeter at seated ear height. If this is
not possible the MPS-1611P must be angled in the vertical plane and toed-in to meet at seated ear height at the center of the
primary seating/monitoring location so as to cover the listening area uniformly with high frequency energy. A green LED has
been mounted on the center axis of the speaker. This LED can be used as an alignment tool for final aiming of the loudspeakers
and indicates perfect on axis alignment when the LED is at its brightest.
If the speakers are not at seated ear height, it is recommend that they not be higher than 15 degrees above that plane.
All five speakers in a surround sound system should be of the same model or with Tripole surrounds for the rear speak-
ers. Sometimes, however, the surround speakers must be smaller than the mains. M&K Professional offers several smaller
models that are timbre matched to our larger speakers.
If the speakers are located behind an acoustically transparent picture screen it is recommended by SMPTE and THX that
they be placed at 5/8 the height of the picture screen. Placing the speakers in this manner will ensure that sound elements
relate best to the image.
When placing loudspeakers around a video monitor, it is best to place all three main speakers either all above or all below
the screen. Placing the center channel speaker on a different horizontal plane from the left and right speakers will create dif-
ferent arrival times and will adversely effect imaging.
NOTE: All M&K Professional main monitors are shielded. However, be careful not to place M&K Tripole surround
monitors near video monitors as the side-firing drivers may gauss the video monitor and distort the visual image.
For the best low frequency match between speakers, we recommend the speakers be placed a minimum of 3 feet (or 1
meter) in front of any wall. If the MPS-1611P is placed inside a cabinet, resonances from the cabinet cavities should be
eliminated; a combination of front baffling, internal dampening, and perforation of the sides and rear of the cabinetry should
