AVLink 128.425UK User Manual

4 or 8-way switcher units that allow the distribution of a stereo amplifier. Simply connect the output of an
amplifier to the selector box, this output can then be distributed to up to four/eight different stereo speaker
sets in multiple locations, each speaker set can be individually activated via the push buttons on the front of
the unit. Ideally suited for buildings where an independent sound control is required for different rooms or
zones.

Features:

• Enables four/eight pairs of speakers to be connected to a single stereo amplifier.
• Heavy-duty push buttons.
• Built-in overload protection.
• Designed for 4-16 ohms speakers.
• Spring clip terminals.

Installation consideration:

AV:Link low-profile speaker selector boxes allow you to distribute a stereo amplifier to multiple zones. All
models include a manually activated impedance protection circuit (Single Pair Direct) that can be turned ON to
prevent the impedance presented to your amplifier from dropping below an unsafe level of 5 Ohm, regardless
of the number and impedance ratings of your speakers.
The protector 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.

Installation:

• The terminals on the rear of the speaker selector will accommodate up to 14-gauge cable which will
suffice for 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 regulations.
