The HTD SS41 (shown above) and SS81 are low-profile speaker selector boxes that allow you to distribute a stereo
high-level (amplified) signal into multiple zones. Both models include a manually activated impedance protection circuit
that can be turned ON to prevent the impedance presented to your receiver from dropping below an unsafe level of 5
ohms, regardless of the number and impedance ratings of your speakers. The protection switch can also be turned off
when used as part of a planned system of impedance matching volume controls, allowing you to get the most out of your
amplifier. Please see the HTD web site for instructions for planning an impedance matching system. If you are unsure,
consult a professional contractor.
Connecting your HTD Speaker Selector
The terminals on the rear of the speaker selector will accommodate 14 gauge cable which will suffice for even long
connections (greater than 100 feet of wire). For shorter distances, 16- or 18-gauge wire will suffice. For behind-the-
wall installations, we recommend using UL Class 3 approved cable (marked "CL3") for compliance with local building
codes. When connecting a speaker and amplifier, it is important to retain the correct polarity. To do this, be sure that
the wire attached to the +, red, or positive terminal on the speaker connects to the +, red, or positive terminal on the
rear of the selector box. Similarly, the –, black, or negative terminal on the speaker must connect to the respective –,
black, or negative terminal on the selector box. Polarity should also be maintained when connecting your amplifier's
outputs to the amplifier inputs on the selector box.
Connecting Speaker Cables
1. Route the speaker cables from the amplifier and from each speaker zone to the speaker selector.
2. Strip 3/8" insulation from the end of the cable and twist the exposed end to avoid fraying.
3. Press on a "push-pin" terminal to reveal an eye into which the twisted cable is inserted; release the terminal to lock
the cable in place.
