TECHNOLOGY
VCRunner PurePath or OptiMatch
Attenuator type: Tapped auto transformer.
Switch: 12 position rotary, make-before-break contacts, low torque specifications for
smooth feel.
Connector: Screw-tight type; 1-stereo input, 1-stereo buss, & 2-stereo outputs
Power rating: UL Listed @ 72 Watts RMS continuous, 35 Hz- 20 KHz, 216 Watts audio.
Core Saturation: Studies reveal that transformer core saturation @ 35 Hz is 72 Watts.
Transformers: Tri-filar wound for flat response and minimum phase shift, grain-oriented,
-34 dB in 12 steps, 8 steps @ -3 dB each, 1 step @ 4 dB, 1 step @ -6 dB,
last step OFF.
Mounting: Fits most standard single gang junction boxes.

permits presetting load impedance multiplication by X2, X4, X8, X16,which can be
changed at any time.
Installation must be made by qualified service personnel, and must meet all local codes.

1. Make connections by stripping the wire insulation back about 3/16". Twist any loose strands tightly.
2. Insert the wires from the amplifier into the INPUT openings of the connector, hot to hot and ground to
ground, then tighten the screws. Check for any loose strands that might cause a short circuit. Make
sure the metal part of the screw connector engages the bare wire, NOT the insulation.
3. Similarly, connect speaker wires to the control OUTPUT openings and tighten screws.
4. If using the impedance matching feature of the OPTIMATCH(tm) control, set the index following the chart
below. To set, remove knob and loosen nut to reposition index. Make sure index is not between detent
positions and tighten.
5. Install the control in its operating location. (SUGGESTION: Leave control 3 or 4 positions CCW from
maximum before firing up the system for the first time to avoid "blasting" the speakers, while still having
enough sound to observe operation.
OPTIMATCH(tm) is a new concept in self-impedance matching controls. It can be used either as a full range
volume control, or as an impedance matching volume control that can be adjusted to meet the requirements of your
installation. One simple adjustment can be made when the control is connected, and can be changed to accommodate
additions to the installation at any time. It is easily retrofitted to almost any existing system.

We do not recommend wiring more than 12 Optimatch(tm) controls in parallel. In these instances more impedance protection
should be inserted before the volume controls. The OC-12 or MS-12 is a good choice in this case.
