• Switching Units - Q. If my amp is rated 6-16 Ω should I really be running a 4 Ω load?

  Answer: No, never; you should use 12 Ω minimum speakers if they are to be parallel wired. You can get 16 Ω speakers, but it may just be easier to change the amp.

• Switching Units - Q. What are the benefits of series vs parallel wiring?

  Answer: The switches which have more than two sets of speakers use a combination of series and parallel switching to achieve the minimum impedance of 4 Ω no matter what combination of speakers are switched on. For the two way switches, there is a ...

• Switching Units - Q. What is the technical definition of 'transmatch'?

  Answer: For the 5 way speaker switch we don't use parallel or series switching, using use transformer coupling instead. Again you have to use 8 Ω speakers minimum if your amp is a 4 Ω minimum amp. The impedance is then matched by the transformer, so ...

• Switching Units - Q. What are the differences between the speaker switches in terms of impedance?

  Answer: All of our speaker switches are configured so that if you use 8 Ω speakers, the minimum impedance seen by the amplifier will be 4 Ω.
