Setting the Impedance Switch

Count the number of speakers you’re con-

necting the volume control to, and if they’re 

4ohm or 8ohm.
• Check the specifications in your amplifier 

or receiver owner’s manual (or on the back 

of the amplifier) to determine if it can sup-

port an 8ohm or 4ohm speaker load.

• Set the impedance switch to the correct 

setting using the 

chart to the right:

• On all volume con-

trols in the system, 

set the impedance 

match jumper to 

the same position.

It’s not recommend-

ed to install more 

than 8 volume controls in parallel. It’s also 

recommended to use additional impedance 

protection when installing more than two 

8ohm speakers per channel on each volume 

control.

Mounting the enclosure 

• If conduit is going to be used, run the wiring 

through the conduit and into the opening 

at the base of the enclosure.

• Using the appropriate adhesive material, 

mount the enclosure into the PVC conduit. 

• Secure the enclosure to a stationary object 

in the wall using the four holes in the back.

Wiring

• Strip ¼ to ½ inches (6 to 12 mm) of the in-

sulation off the connection cables. To avoid 

stray strands, twist them at the end. Twist 

the input wires with the volume control in-

put wires. (Make sure all cables are consis-

tent with polarity.)

• Run the output cables from the amplifier to 

the volume control’s input wires. 

• run the cables from the volume control’s 

output to the speaker’s input. 

Install volume control in the enclosure

• Put volume control into the enclosure.
• For the OV100, place cover plate over the 

enclosure ensuring that the plastic rubber 

gasket is in place behind the cover plate. 

Place the control knob on the volume con-

trol.
