Cambridge SoundWorks MC630HD User Manual

-  -

  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 MC630HD accept bare wire 

between AWG #12 and AWG #18 (lower numbers are thicker). It is 

not necessary to “tin” the wire or use connectors 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.

Determine how long the speaker cable should be for each 

speaker. Cut the speaker cable into the appropriate lengths. 

Route the wire to each speaker location. 

Strip 1/2 inch of insulation from the two individual conductors 

in the speaker cable. Twist the exposed strands of bare wire 

together.  

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

Press the speaker’s red terminal to expose the hole in its shaft. 

Insert the stripped end of one cable’s positive conductor into the 

speaker’s red (+) terminal. 

Release the terminal to secure the connection. Make sure no 

stray strands of wire are present. 

Repeat the procedure for the cable’s other conductor and the 

speaker’s black (–) terminal. 

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).

Repeat the process for each speaker.
