APPLICATIONNOTES

Connections

If your amplifier or receiver has "A" and "B" speaker pair outputs, connect the SPS-6to the "A" points.Do not connect anything to "B". This will prevent the amplifier or receiver from driving an unusually low impedance load.

Using the SPS-6with Tube Type Amplifiers

Virtually all tube amplifiers must have a load connected at all times. If the amplifier to be connected to the SPS-6is a tube amplifier, be sure to always have at least one pair of speakers switched on at all times. An alternative is to permanently connect a 150 ohm, 5 watt resistor across the tube amplifier's output in parallel with theSPS-6.

Impedance Matching

You will need to activate the SPS-6'sPROTECTION button whenever the overall system impedance might fall below 4 ohms.
