HDA: DAISY-CHAINING MULTIPLE LOUDSPEAKERS
Hookup Diagrams
One convenient feature of the Mackie HDA loudspeaker system is the ability to connect multiple loudspeakers
together easily, as shown in the illustration above.
If only one HDA is required, connect the mixer output to the HDA’s XLR MAIN INPUT using a balanced XLR
cable. The HDA is powered via the supplied Neutrik PowerCon
®
cable connected to the AC MAINS jack. See the
following page for details on this type of setup.
If multiple HDAs will be connected, start with the instructions as listed above. Next, connect the fi rst HDA’s XLR
LOOP OUT jack to the second HDA’s XLR MAIN INPUT jack using a balanced XLR cable. A short 1-2 foot cable
is all that is necessary. Hook up the supplied loop Neutrik PowerCon
®
cable from the fi rst HDA’s AC LOOP jack
to the second HDA’s AC MAINS jack. A maximum of four HDAs may be daisy-chained together in this fashion
from a single 20A source.
See pages 8-12 for systems utilizing multiple HDAs in various setups. See page 15 for more information
regarding powering the Mackie HDA loudspeaker.
