Basic Wiring Overview
70V/100V Line Systems
For 70V/100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire rated to
handle the total output of the amplifier.
Connect the “70V” or “100V” output terminal to the positive (+) connection of the speaker and “COM” output to the negative (-)
connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals connected together
and all negative terminals connected together as shown below.
A 70V/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 80% of the amplifier’s output power rating.
The terminals of a 70V/100V speaker are connected to a transformer and in some cases, this transformer may be “tapped” for
different power ratings. These tap settings 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 Speaker Terminals
The MixAmp-60 offers three low impedance options of 4Ω, 8Ω, 16Ω depending on the speaker load. Please note that one wire
only should be connected to the speaker output COM screw and one wire to the selected speaker output. Low Impedance
(4/8/16 ohms) and high impedance (70V/100V) cannot be used simultaneously.
