NX-SSVC6 6-Zone Automatic Impedance Matching
Speaker Selector with Volume Controls
Congratulations on choosing the NX-SSVC6 Impedance Matching Speaker Selector
Like all NXG products,
tion of advanced engineering and state-of-the-art
great care has been taken in its design. We hope the combina-
materials will provide you with a
.
lifetime of listening pleasure.
Introduction
The NX-SSVC6 is a resistor based, impedance matching speaker selector/volume
controller used for connecting six pairs of (4 ohm or 8 ohm) speakers while maintaining a safe impedance load for your receiver or amplifier. The NX-SSVC6 allows
you to adjust the volume of any pair of speakers independently. Additionally, each pair
of speakers can be selected (on/off) independently in any combination, by the pushbuttons on the front of the unit, without concern for amplifier loading.
Features and Benefits
1. Connect and safely control up to six speaker pairs with one amplifier.
2. Built in automatic impedance protection circuitry engages without the need for user involvement.
3. Individual room on/off control via the front mounted pushbuttons.
4. Individual room volume via the front mounted 12 position rotary controls.
5. Heavy-duty screw-type connectors, capable of accepting up to 12 AWG wire, provide positive hookup to input and output wires.
6. Isolated left/right circuit grounds provide safe connection for amplifiers with floating grounds or bridged configuration.
7. High quality construction throughout provides excellent reliability, accurate switching, and noise-free volume control.
8. Intelligent design allows simple installation, easy connection, and trouble-free operation.
9. Rubber feet prevent scratching and keep selector in place during operation.

Wiring Instructions
Follow the suggestions that came with your receiver or speakers for determining the correct wire gauge needed to connect your NX-SSVC6
speaker selector. Lay out all wire runs from each speaker location and your receiver to your selector. Remove the connector blocks from the
selector and make all the connections to the connector blocks as shown in Figure 1. (If your receiver or amplifier has both A & B outputs connect your NX-SSVC6 to your receiver’s A outputs.) Pay close attention to make certain all strands of bare wire are completely inserted into the
connector properly and that no loose strands are outside the connector hole. Any loose strands could possibly touch another wire and short
the receiver’s output. After you have tightened the screw terminals to secure the wires, insert the connector block back into your selector as
shown in Fig 2.

Setting the NX-SSVC6 Volume Controls
This procedure will allow you to properly set the volume of
your system to avoid overdriving the NX-SSVC6 and or your
speakers to avoid damage or amplifier distortion (clipping).
1. Set your receiver’s volume control to the minimum
setting.
2. Turn each volume control
on the NX-SSVC6 to it’s
maximum setting.
3. Now, slowly turn the volume up on your receiver until
you get the maximum volume (without distortion) you
want in any given room that’s
connected to the NX-SSVC6.
4. Now you can attenuate
the volume of each room
independently to achieve the
proper listening level in each
room.
