SS4 Speaker Selector Impedance Matching 1 Input 4 Output
The SS4 is a low-profile speaker selector that allows you to distribute a stereo speaker-level (amplified) signal to multiple listening zones. These speaker selectors feature a manually activated impedance protection circuit. The protection switch can be turned ON to prevent the impedance to your amplifier from dropping below 5 ohms, regardless of the number and impedance ratings of your speakers. The protection switch can be turned OFF when used as part of a system incorporating impedance matching volume controls, allowing you to get the most out of your amplifier. The terminals on the rear of the speaker selector will accommodate up to 14 gauge cable; sufficient for cable runs exceeding 100 feet. For shorter distances, 16 ~ 18 gauge cable will suffice. For in-wall installations, we recommend using CL-2 or CL-3 rated cable for compliance with local building codes. If unsure, contact you local building inspector. When connecting a speaker and amplifier, it is important to maintain polarity; positive (+/red) to positive and negative (-/black) to negative. Be careful to maintain correct polarity between the amplifier, the speaker selector, the volume controls and the speakers. Power: 70 watts/channel impedance protection off, 140 watts/channel impedance protection on. Dimensions: 8-1/2" W x 2-1/8" H (with feet) x 5" D (including wire terminals and push buttons).
