SS6 and SS4 Speaker Selector

Installation Instructions

Adding Speaker Volume Controls

We recommend that you connect all your speakers to in-wall volume controls (like the Sonance VC60S/R) and then to the speaker selector (see ‘Rooms 2 – 6’ in Figure 2, on page 3). This gives you independent volume balancing and control in all speaker locations: Your receiver's volume control acts as the Master Volume, and each individual pair of speakers can be either OFF, or ON at its own volume level, independent of the other speakers connected in the system.

Protecting the Amplifier

The speaker selector includes a Protection switch located underneath the selector, on the right side. To protect your receiver or amplifier Sonance strongly recommends that you leave the Protection switch engaged at all times. Always operate your receiver or amplifier within its rated power range and within the power range of the speaker selector.

•To ENGAGE the Protection circuit, slide the red switch towards the back of the selector.

•To DISENGAGE the Protection circuit, slide the red switch towards the front of the selector.

Important: Turning the protection switch OFF allows greater power to your speakers, but may damage your receiver/amplifier.

Automatic Internal Fuse

The SS6 and SS4 have an internal fuse that will disconnect all of the speakers if the current draw through the unit exceeds a safe level. After the current draw returns to a safe level the fuse will automatically reset and re-connect all of the speakers.

Important: If the speaker selector continually turns the speakers OFF and ON, one or more of the following unsafe conditions exists in the audio system:

•The amplifier’s volume is set too high.

•The amplifier’s power output exceeds the Maximum Amplifier Power ratings as described in the Specifications section below.

•There is a short-circuit in one or more of the speaker wires.

To ensure safety, correct any and all of these conditions before operating the audio system again.
