Speaker lines connection

For the amplifier output connectors is recommended to use high-quality cable. To prevent the
possibility of short-circuits, insulate exposed loudspeaker cable connectors.
The equipment includes 5 terminals for individual 100 V speaker outputs and a terminal for low
output impedance of 4 Ω. The following figure shows speaker output terminals.
Never use both the Low-Z (4 Ω) and Hi-Z (70V and 100 V) terminals at the same time.
Select the appropriate wire size based on the distance between amplifier and speakers.
In order to change the output voltage of High impedance terminals the following internal connection
has to be done.
