Frequently Asked Questions - PDVC50 Power Dynamics

What is the maximum power supported by the PDVC50?

The PDVC50 supports a maximum power of 50 watts per channel. Make sure your amplifier does not exceed this limit to avoid damaging the controller.

How to install the volume controller?

Install the PDVC50 in a standard electrical box. Connect the 4-conductor cable from the amplifier to the input terminals, and the 2-conductor cables from the speakers to the output terminals. Respect polarities (+ and -) and tighten the wires securely.

Can I use this controller with 4 ohm speakers?

Yes, but the maximum power of 50 W per channel is defined for a standard impedance. Check compatibility with your amplifier and respect the total power to avoid saturation.

How many speakers can I connect?

You can connect multiple speakers in parallel on each channel, as long as the total impedance does not drop below the minimum value supported by your amplifier. The PDVC50 handles up to 50 W per channel regardless of configuration.

How to clean the device?

Use a dry cloth to clean the housing. Never use chemicals, aerosols, or liquids, as they could damage the finish or cause short circuits.

What to do in case of malfunction?

If the PDVC50 does not work properly, disconnect all cables and check the connections. If the problem persists, contact a qualified technician. Do not attempt to repair the device yourself, as this would void the warranty.

Does the controller require electrical power?

No, the PDVC50 is a passive device: it does not require any mains power. It simply attenuates the audio signal from the amplifier to the speakers.

Can I mount the controller directly in the wall?

No, you must mount the PDVC50 in a standard electrical box, either flush or surface mounted. Never install it bare in the wall for safety and compliance reasons.

What is the warranty?

The warranty is valid if the instructions in the manual are followed. Any unauthorized modification or repair voids the warranty. Keep your proof of purchase and contact your Power Dynamics dealer.

How can I tell if the installation is correct?

After installation, turn the volume knob to the Full Off position and then increase gradually. Check that the sound is clear and without distortion. Ensure that polarities are respected to avoid phase issues.

CONNECTIONS

1. Run 4-Conductor speaker cable from the amplifier (positive and negative for both the left and right channel) to the volume control marked 1 and 2. Similarly, run 2-conductor speaker cable from each of the first pair of speakers to the volume control. Label the cables for future reference.
2. Measure the depth of the volume control to make sure your Volume Control will fit in the box.
3. Connect the speaker cable to the volume control: a. Strip 6mm 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 4-conductor speaker cable from the amplifier into the input terminals. d. Insert the two 2-conductor speaker cables from the first pair of speakers into the output terminals.
4. Connect additional speakers in parallel.
5. Make sure that all connections between your amplifier and the volume control, and between the volume control (3) and each speaker, are in "phase", that is (+) to (+) and (-) to (-).
6. Turn the volume knob to the "off" position (all the way down.)
7. Screw box into place.
8. Put on faceplate and screw in place using the screws.

Caution: This volume control is limited to a maximum of 50 watts maximum per channel.
