The RSVC4 is a combination of a speaker selector and volume controller. It allows you to connect different loudspeakers to one
amplier without risk of overloading. The RSVC4 resolves the impedance problem and controls the volume per pair of speakers. Each
speaker pair can be switched on or off with the on/off button. This application is ideal for background music.
The RSVC4 is designed for use in combination with a low-ohm amplier rated at 2 x 80 W RMS. Any damage caused by use with am-
pliers of a higher rating is not covered by the guarantee.
DO NOT use the RSVC4 with an amplier rated at higher than indicated.
The more loudspeakers you use per amplier, the greater the impedance or load. If, for example, you connect two pairs of speak-
ers of standard 8 ohm, the impedance will drop to 4 ohm. The load is then twice as high. If you connect still more loudspeakers, the
impedance will drop to 2 ohm. An amplier like that can deal with 4 ohms of load. At any higher load there is a real risk of damage. The
RSVC4 solves that problem.
1. Make sure your amplier is off.
2. Set the volume knob of the speaker pair you plan to connect (e.g. zone 1) to maximum.
3. Set the corresponding knob (e.g. zone 1) to ON
4. Switch the amplier on and choose a source
5. Slowly increase the volume of the amplier until you get the desired sound level.
6. You can now use the RSVC4 to adjust the volume per zone and set accents.
7. You can switch off the loudspeakers by setting the knob to OFF or by turning the volume fully down (knob)
8. Never connect more than 2 speakers per zone output
We recommend use of a exible cable of 0.75 mm – 1.5 mm thickness.
When arranging the cables, keep the RSVC4 several inches away from any existing cables (e.g. electricity).
a. Feed each cable into the correct terminal on the rear, red and black
b. Trim two millimeters of insulation from the cable before feeding it in. Press on the lug to open it and push the cable in.
c. Now release the lug. The cable is xed in place. The input from the amplier to the RSVC4 (same cable!) is via “AMPLIFIER”.
Connect the loudspeakers via “SPEAKERS”. The RSVC4 needs NO main current.
d. Make sure that positive and negative poles are connected correctly.
