Description
Download Manual The SS-4 is a 4-pair speaker selector designed to let a single stereo amplifier or receiver drive up to four separate speaker pairs. It provides safe multi-room or multi-zone speaker distribution while preserving amplifier protection. The unit supports continuous music power rated at 100 watts per channel and a peak capability of 200 watts.
Key features include an internal protection circuit that prevents amplifier overload when multiple speaker pairs are used simultaneously, and separate left and right ground paths for compatibility with bridged amplifier designs. The selector uses removable screwless connectors that accept 14-22 gauge speaker wire and ships with adhesive-backed room identification labels. The chassis is constructed from metal and includes nonskid feet for stable tabletop placement.
Audio performance is effectively transparent across the audible band, with a flat frequency response from 20 Hz to 20 kHz. The SS-4 handles 100 watts continuous music power per channel and accommodates speaker systems that permit a 4 ohm load on the amplifier. The protection circuitry engages automatically to safeguard the connected amplifier when multiple loads are presented.
Connectivity is straightforward: individual runs of two-conductor speaker wire are required for each speaker pair and the removable connectors simplify installation and maintenance. The unit is compatible with standard two-conductor speaker cable and is recommended for 16 gauge wire although 14-22 gauge is supported. There are separate binding terminals for left and right channels to maintain proper polarity and grounding.
Typical applications include whole-home audio distribution, multi-room stereo installations, and smaller commercial audio paging or background music zones where control of multiple speaker pairs from a single amplifier is required. Installers can select any single pair, any combination of pairs, or all pairs simultaneously while relying on the built-in protection circuitry. The included room ID labels help keep multi-room deployments organized during setup and service.
Installation is designed to be quick and reliable on a tabletop or entertainment component shelf, requiring only individual speaker runs and a compatible amplifier that supports a 4 ohm load. The rugged metal chassis and screwless connectors reduce installation time and increase reliability in regular use. Overall, the SS-4 delivers a practical, protection-focused solution for driving multiple speaker pairs from one amplifier.
