OSD Audio TSM12 Black

12 Zone, 100W RMS, 4 Ohms, 14 AWG <b>DUAL SOURCE 12 ZONE SPEAKER SELECTOR</b>
If you want a powerful speaker selector, the TSM-12 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. This high quality speaker selector is designed for use with either 4 or 8 ohm speakers. The A/B switch located on the front panel allows all your speakers to be driven from either of two amplifiers.

The TSM-12 speaker selector is equipped with a low-frequency protection circuit to reduce subsonic signals. This allows higher power operation without amplifier shut-down. Utilizing audio-grade impedance-matching autoformers, the TSM-12 is capable of maintaining a safe operating load at the amplifier while distributing maximum power throughout your system. The TSM-12 is equipped with a rotary switch, located on the rear panel, which is used to set the appropriate impedance to be seen by your amplifier, based on the number of pair of speakers connected. This switch selects the proper taps of the autoformers, allowing the amplifiers power to be delivered safely to the speakers.
