Amplifier
Never use both the Low-Z (8 Ω) and Hi-Z (100 V) terminals at the same time.
Select the appropriate wire size based on the distance between amplifier and speakers.
3.5. External equipments connection
By connecting a signal processor such as an equalizer or limiter between the mixer section (PRE-
AMP OUT) and the power amplifier section (AMP IN), signals can be tuned for desired sound
output.
Note: Inserting a 1/4-inch phone plug into AMP IN terminal disconnects internal power amplifier
section from the mixer section.
3.6. Expansion
This amplifier allows expansion with LINK IN and LINK OUT connectors. If you need more inputs
and outputs, you can use these connectors to link the amplifier to another unit.
