-
Single Pair Direct Switch – impedance protection switches the amplifier/receiver.
-
Connection from amplifier – from the L (left) and (right) loudspeaker output of your receiver or amplifier ( 100 watts MAX )

pairs
Installation Tips
- 16 or 18-gauge stranded loudspeaker wire is recommended. 14 gauge is recommended for runs longer than 50 feet.
- You can mix any combination of 4, 6, 8, and 16-ohm loudspeakers
- Wire according to local laws. Specific ” CL ” fire ratings may be required according to your local building codes. Your dealer may know more about obtaining such wire.
- Avoid running close to AC power wiring for safety and to avoid the possibility of picking up any noise.
Installation
ISS4, ISS6, ISSB Speaker Selectors
Thank you for giving OSD AUDIO the chance to win your business! We are confident you will find that OSD offers an outstanding combination of performance and value in everything we make. To ensure you get the most out of your new amplifier, please take a moment to read this manual before you get started .
Features
The OSD ISS4, ISS6 and ISSB are low-profile speaker selector boxes that allow
you to distribute a stereo highlevel (amplified) signal into multiple zones.
All 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 Ohm, regardless of the number and impedance ratings
of your speakers. The protecting switch can also be turned off when used as
part of a planned system of impedance matching volume controls, allowing you
to get most out of your amplifier. If you are unsure, consult a professional
contractor.
Connecting your OSD Speaker Selector
The terminals on the rear of the speaker selector will accommodate up to 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 is 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
output to the amplifier on the selector box.
Connecting Speaker Cables
- Route the speaker cables from the amplifier and from each speaker zone to the speaker selector.
- Strip 3/8″ insulation from the end of the cable and twist the exposed end to avoid fraying.
- Press on a “push-pin” terminal to reveal an eye into which the twisted cable is inserted; release the terminal to lock
