Russound SS-4.2 - Impedance Matching Single Source - Four Pair Speaker Selector

Single Source - Four Pair Resistor Based - Impedance Matching Speaker Selector
Description

The most important and most forgotten about subject in getting reliable and high quality distributed audio is arguably impedance matching...Forget these fundamentals and you will open up a host of issues!

The SS-4.2 allows you to switch up to four speaker pairs connected to a stereo amplifier. Offering high-quality audio performance, it also provides overload protection and long-term reliability.

The SS-4.2 offers two operating configurations: Impedance Matching and Bypass. Impedance-matching mode provides automatic overload protection for use even with high-power amplifiers. This mode allows multiple pairs of speakers to be safely connected to an amplifier using the built-in automatic impedance-matching circuitry.

Bypass mode is used for direct speaker switching with remote impedance-matching volume controls. This allows local control in each room as well as higher efficiency; however, in this mode the impedance matching and overload protection are not engaged.

Designed for use with 8-ohm loudspeakers, the SS-4.2 also provides safe connection to bridged amplifiers and even works in applications where there is a floating ground. It has spring-loaded speaker terminals for quick connection and can accommodate speaker wire up to 12 gauge.
