100V line systems
For 100V line systems, connect the amplifier to the first speaker in the system using double-insulated
speaker wire which has adequate current rating to handle the total output of the amplifier.
Connect the “100V” (10) output terminal to the positive (+) connection of the speaker and “COM”
output (8) to the negative (-) connection of the speaker. Connect further speakers in parallel to the
first speaker with all positive terminals and connected together and all negative terminals connected
together as shown below.
A 100V line speaker system can comprise of many speakers connected together. The determining
factor for how many speakers can be used on a single amplifier is the power rating. For most
purposes, it is advised to connect as many speakers as needed with a combined wattage of no more
than 90% of the amplifier’s output power rating.
The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer
may be “tapped” for different power ratings. These tappings can be used to adjust the wattage (and
output volume) of each speaker in the system to help achieve the ideal total power of the system for
the amplifier.
Low impedance systems
The RS series slave amplifiers can provide an output for a single 8Ω speaker by connecting the “8Ω”
output (9) to the positive (+) speaker connection and “COM” output (8) to the negative (-) speaker
connection. It is important to ensure that the speaker load is no less than 8Ω and that the power
handling of the speaker is equal to or greater than the output power of the amplifier.
