Cambridge SoundWorks MC630HD manual System Configuration, Speaker Placement

System Configuration

For the most balanced performance use an MC630HD on all channels of the surround-sound system. They are also excellent to use as rear or surround speakers in a system using MC650HD front speakers. If you prefer smaller or in-wall surround and rear speakers, any of the Cambridge SoundWorks Newton Series speakers may be substituted with good results. The Left, Center, and Right speakers should all be the same for the most accurate sound stage.

The MC630HD is intended for use in systems that contain one or more subwoofers, and is not designed to reproduce the deep bass range. Use a receiver or AV processor that incorporates a high-pass crossover whenever possible. If you must use the MC630HD with a receiver or amplifier that does not contain a high-pass filter, make sure the “o” or “wall” side of the bass contour switch adjacent to the input terminals is pressed. Setting this switch to “” or “Stand” when driven with a full-range signal can result in damage to the speaker if the signal contains strong bass.

Speaker Placement

The proper placement of speakers affects how well the AV surround system recreates the sound field intended by the recording engineer. Current recording practice typically assumes a speaker array with a center channel speaker directly in front of the central viewing position. Left and right speakers are placed so they each form a 30 degree angle from the centerline. Left and right surround speakers should be 110 degrees from the centerline. Left and right rear speakers in a 7.1 system should be at 140 degrees. If a single rear speaker is used in a 6.1 system, it should be centered on the rear wall. Front speakers should be as close to the height of the TV monitor as practical. Surround and rear speakers should be slightly higher. Recreate this speaker pattern as closely as your room and furnishings allow.

Don’t be too concerned if your situation and listening environment dictate the speakers’ position. Most rooms do not allow ideal placement. Place your speakers as close to these guidelines as practical. The speakers will still provide convincing, lifelike sound.

Your surround processor has a variety of adjustments to optimize the sound based on the speakers’ capabilities and placement. These adjustments vary by processor, so refer to your processor’s manual for instructions specific to your equipment. Set your main, center, and surround settings to “SMALL”, with subwoofer “ON”. If your processor allows you to adjust the crossover frequency, set it as close to 100Hz as possible.

•Avoid placing front left and right speakers very close to a side wall (within 12-14 inches). The reflected sound from the wall degrades the sound coming directly from the speaker.
