The design team at Cambridge SoundWorks believes there is no better combination of audiophile-level attention to detail and reasonable cost. AFTER UNPACKING 2. Store the shipping carton and packing material for future use and transport. CONTENTS 1. One Speaker 2. Two stick-on rubber feet 3. Center Channel rear support 4. Wall mount bracket 5. Four screws and wall anchors 6. Logo Badge 3. 1. INSPECTING FOR DAMAGE Examine each part carefully for shipping damage. If there is any, do not install or use the speaker. Return the speaker to the merchant where you made the purchase or call Cambridge SoundWorks at 1-800 FOR-HIFI (1-800-367-4434) for assistance. 5. 4. 6. 2 SPEAKER PLACEMENT The proper placement of speakers affects how well the AV surround system recreates the soundfield 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 sin- gle rear speaker is used in a 6.1 system, it should be cen- tered 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. RECOMMENDED DISTANCE APART FOR STEREO 20 -55 ANGLE APPROX. EAR LEVEL Don’t be too concerned if your situation and listening envi- ronment 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 MAXIMUM RECOMMENDED DISTANCE 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 SURROUND SURROUND SPEAKER SPEAKER 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. 7.1 REAR 7.1 REAR SPEAKER SPEAKER • 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.

MAIN SPEAKER MAIN SPEAKER 3 WIRING THE SPEAKERS If you wish to conceal the wire within the walls, it is easiest to run the wires to their final positions prior to mounting the speakers. The spring loaded terminals of the MC650HD accept bare wire between AWG #12 and AWG #18 (lower numbers are thicker). It is not necessary to “tin” the wire or use connec- tors to terminate the wire. • Use at least AWG #18 speaker cable for short runs (under 15 feet). Use AWG #16 or heavier speaker cable for longer runs. • Building codes typically require plenum rated wire for installation within walls. Be sure to use wire that complies with any applicable local building codes. Plenum rated cable typically has an outer jacket with individually insulated conductors inside the outer jacket. Some brands of plenum rated cable may be too thick to fit the space between the wall mount bracket and the speaker. To use heavier plenum rated speaker cable with the wall mount brackets, remove the outer jacket and any filler cord back to the point where the wire exits the wall. Preparing the wires: 1. Determine how long the speaker cable should be for each speaker. Cut the speaker cable into the appropriate lengths. 2. Route the wire to each speaker location. 3. Strip 1/2 inch of insulation from the two individual conductors in the speaker cable. Twist the exposed strands of bare wire together. 4. Determine which conductor you will use to connect the positive terminals of the amplifier and speaker together. Printing or a ridge on the insulation usually distinguishes one of the two conductors. Sometimes the metal of the conductors has two different colors, or the insulation color of each conductor may be different. Strip 1/2 inch 4 TO ATTACH THE WIRES 1. Press the speaker’s red terminal to expose the hole in its shaft. 2. Insert the stripped end of one cable’s positive conductor into the speaker’s red (+) terminal. 3. Release the terminal to secure the connection. Make sure no stray strands of wire are present. 4. Repeat the procedure for the cable’s other conductor and the speaker’s black (–) terminal. 5. Connect the opposite end of the speaker cable to the speaker outputs of your receiver. Remember to observe channel and polarity (Left Positive, Left Negative, Right Positive, Right Negative). 6. Repeat the process for each...
