INSTALLATION MANUAL

TECHNOLOGY

VCMute / VCPage & VCPage-Base

SPECIFICATIONS

INSTALLATION

Attenuator Type: Tapped auto transformer.

Switch: 12 position rotary, make-before-break contacts, low torque specifications for smooth feel.

Connectors: Screw-tight type.

Power rating: 72 Watts RMS continuous, 35 Hz-20KHz, 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 two-gang junction boxes.

OptiMatch Will match impedance for almost any situation. Mechanical index permits presetting load

impedance multiplication by X2, X4, X8, X16, which can be changed at any time.

Requires: VCPage-Base for page amplification, mute control and infrared operation.

Size: 17"W x 4.5"D x 1.75"H

Power Supplies: 12v DC (plug into switched outlet of audio receiver; 16v AC (plugs into constant powered outlet).

Zones: Capable of paging into 10 VCMutes (9 if using the Doorbell Interface).

Connectors: Depluggable Connectors.

Power rating: 60 watt paging amplifier.

RCA Input: Line level page input for interfacing with paging phone systems.

Infrared Output: Three IR emitter outputs (1/8" jacks).

Recommended Wire: CAT-5 (seven conductors of the eight conductors will be required to operate the VCMute and

VCPage system. The eighth conductor will be required if infrared is added to the system---see

IR Repeating and IR Emitter Output.

Following the wiring diagram on the back of this manual;

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. Finally make the Mute and Page connections in the same way. Connect the power supply last.

All VCMute and VCPage units must be wired in the HOME RUN method directly to the VCPage-Base unit.

5. If using the impedance matching feature, make sure the factory setting of 4X is acceptable. If not, make the

appropriate change using the chart located on the wiring diagram.

7. Install the control in its operating location.

Installation must be made by qualified service personnel, and must meet all local codes.

OptiMatch and PurePath versions

VCMute / VCPage

VCPage-Base

Your VCMute / VCPage is available as either a full range volume control (PurePath) or as an impedance matching version

(OptiMatch) capable of adjustment to meet the requirements of your installation.

If using some other device such as an impedance matching audio switcher (AT-Series, PT-Series, MS-Series) or a distribution

hub (MJ-1 or OC-12), you may use the PurePath version of the VCMute with 12 steps of attenuation. If you wish to use the

VCMute volume control to impedance match the system, every OptiMatch unit is factory set at the 4X postion--- capable of

correcting 4 pairs of 8 ohm speakers wired in parallel to appear as an 8 ohm load on the amplifier. If using more than 4 pairs

of speakers, please refer to the OptiMatch chart included in this manual to adjust the Opti Peg setting. ONLY ONE PAIR OF

SPEAKERS PER VOLUME CONTROL.

NOTE: No more than 10 VCMute / VCPage units controlling only one pair of speakers each can be installed in a

single system. If utilizing the VCPage Doorbell Interface (VCPage-DBI) only nine VCMute / VCPage units

can be installed in the system.
