70V Speaker
Volume Controls
Model: VC70-50R and VC70-100R
User Manual
Features and Technical Information:
- Can be used with 70V speakers
- 10 steps of attenuation: The first position is “off” steps 1 through 7 at 3db each, steps 8 and 9 at 6db, and the final position allows the signal from the amplifier to pass through completely.
- Frequency response: 20 Hz to 20kHz (+0/-2db) at rated power
- Input and Output connections accept up to 16 gauge speaker cable
- Fits most deep single gang electrical junction boxes
Installation:
- Select a convenient mounting location for the volume control.
- Run 2-conductor speaker cable from the amplifier (positive and negative) to the volume
control. Similarly, run a 2-conductor speaker cable from the first 70V speaker to the volume control. Connect all additional 70V speakers in line with the first 70V speaker. Label the cables for future reference. - Connect the speaker cable to the volume control:
a. Strip 1/4″ of insulation from the end of each cable
b. Tightly twist the wires in each cable until there are no frayed ends
c. Insert the 2-conductor speaker cable from the amplifier into the input terminals
d. Insert the 2-conductor speaker cables from the first speaker into the output terminals - Connect additional speakers in parallel.
- Make certain that all connections between your amplifier and the volume control, and between the volume control and each speaker, are “phase correct”, that is + to + and – to -.
- Turn the volume knob to the “off” position (all the way counterclockwise), turn on the amplifier, and test the functionality of the volume control.
Installation Considerations
- Type of Speaker Cable
For most applications, we recommend you use 16 gauge, oxygen free copper (OFC) speaker cable for the volume control connections.
