Features & Specifications

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. 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-8 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-8 is capable of maintaining a safe operating load at the amplifier while distributing maximum power throughout your system. The TSM-8 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.

QUESTIONS & ANSWERS

By John from Lawrence, KS on September 16, 2012
Should I be able to test the ohms coming out with a multi-meter? I have installed this box for my system and have 8 speaker pairs hooked up to it. The speakers are 8 ohm speakers and the amp is an 8 ohm amp. If I understand correctly, after I have all 8 speaker pairs hooked up and I turn the dial to 8 speaker pairs, I should be able to test the Ohms coming out of the Amp by putting the multi-meter into the Amp A or Amp B circuitry. Unfortunately, I'm getting a reading of 0 ohms so I'm assuming something is wrong.

Answer:
Hi John,
You would not get an accurate reading from the speaker output on an amp. The TSM-8 has impedance matching; therefore, the speaker selector will appear (to the amp) as an 8 ohm load. Do you have everything hooked up? How does it sound?

Rapid delivery and works as advertised
January 13, 2017
The unit is doing its intended job as advertised, i.e, impedance matching a system with multiple speakers in parallel. I personally had a problem making reliable connections to my system because my cables are #12 gauge.and as the manufacturer's info specified, the maximum accepted is #14. However, I tried using a higher gauge but it was too fine (probably around #18) and would not clamp securely into connectors. I have found these types of connectors to be a general nuisance and would recommend a change. Their one asset is that they're small and the manufacturer can squeeze connections for eight speaker pairs onto the back of the unit.
Pros:
Works as advertised.
Cons:
Some fine gauge wire may not be securely connected (clamped).

Replaced a much more expensive piece.
August 3, 2012
This product will allow you to connect up to 8 pairs of speakers to one amp without overloading the circuitry. The speaker connectors are large and clumsy, and the name tags go into the middle of the buttons. Other than that ... very much like the name brand piece this replaced.
Pros:
Easy To Use, Easy To Set Up, Quality Construction
Best Uses:
Replacement, Upgrade

Good value but metal box is really cheap
August 29, 2011
We use the product to switch one amplifier to numerous demo speakers. Unit works well, but the metal construction is poor.
Pros:
Easy To Setup, Easy To Use
Cons:
Flimsy Construction
