All channels are capable of both Low-Z and Hi-Z (70V or 100V) outputs.
Output impedance is selected by a combination of impedance switches and the active preset. Where presets include subs, these channels are fixed at low impedance.
It is critical that the correct connections are made using the appropriate 'Euro Block' connectors, supplied with the unit. As usual, ensure the amplifier is off when connecting loudspeakers and check that you have used the correct combination of pins for your application.
Be aware that the Hi-Z output pins can deliver voltages of up to 100 volts!
Output connections from SmartAmp are achieved via male 'Euro Block' connectors. Ensure that speaker connection polarity is correct throughout the installation: positive (+) amplifier terminals should always be connected to positive speaker terminals and negative (-) amplifier terminals always connected to negative speaker terminals.
Together with DIP switch configuration, the output connector blocks provide connection options that enable channel independent selection of Hi-Z or Low-Z mode. Connecting cables to the supplied female output connector, and the selection of Hi-Z or Low-Z connection options as shown in the diagram below.
