8-Zone Dual Source Speaker Selector with Amplifier Protection Circuitry and Removable Input/Output Connectors - TSM8

Quick Overview

If you want a powerful speaker selector, the TSM-8 is a highly efficient dual source, impedance-matching speaker selector. It will handle more power and in cooler temperatures than the resister based speaker selectors.


Designed for whole-house audio systems or commercial/retail environments, the TSM8 is a powerful yet affordable dual source zone speaker selector that allows you to connect up to eight pairs of speakers (eight listening zones) and select the zones with front panel push-button controls. A passive device that connects to a high-current amplifier and is compatible with in-wall volume controls, the TSM8 speaker distribution system also includes dual source switching (A/B) so you can choose between two audio amplifiers as well as individual on/off switches for each zone.

Equipped with Impedance Protection
This high-power speaker selector is equipped with a low-frequency protection circuit to reduce subsonic signals so you can drive multiple pairs of speakers without going below safe impedance ratings. Going below the impedance rating can overheat or even damage expensive equipment or cause the amplifier to automatically shut off. The TSM8 utilizes audio-grade impedance-matching autoformers to safely distribute maximum power throughout your system, and a rotary switch located on the rear panel can be used to set the appropriate impedance to be seen by your amplifier based on the number of pair of speakers connected.

Ease of Use and Installation
Accepts up to 14-gauge speaker wire, the TSM8 includes removable 4-pole color coded snap-in amplifier and speaker connectors for ease of installation when terminating. Another feature popular with our customers are the included die-cut labels that can be attached to each button to identify each listening, for example kitchen, patio, etc.
