3)
Do not place the Z-12 on carpeting or any other material that could obstruct airflow
through the ventilation holes in the bottom of its chassis.
4)
Never stack the Z-12 between other components because hot air will quickly become
trapped and cause overheating of the amplifier and the other units. It’s best to mount
the Z-12 above your other components.

Connection Precautions
Leave the AC cord disconnected before and while making or changing any input, trigger, or
speaker connections. Make sure there is no strain or tension on any connections that could
cause them to eventually pull loose.
Input Connections & Input Assignment Switches
You can select or “assign” different inputs to each of the twelve amplifier channels. The four
position Input Assignment Switches designate the source from which each channel receives
its signals.
You can assign each input to receive its signal from the Main Left Input or Main Right Input,
a mono sum of both the Left and Right Inputs, or its independent input jack.

Main Left and Right Input Connections
The Left and Right Input jacks feed two signal paths (“buses”) that are distributed to all twelve
amplifier channels. The Input Assignment switches let you choose whether each of the twelve
amplifier channels receive an input from the Left or Right Input Bus or a mono sum of the Left
and Right Input Buses.
Looping Output Connections
The Right and Left Loop Out jacks provide a convenient way to connect an additional
amplifier to receive the same input signals as the Right and Left Main Inputs. Once you have
connected a source to the Z-12 Main In jacks you can connect the Loop Out jacks to the input
jacks of an additional amplifier. This feature eliminates the need for a “Y” connector between
your source, the Z-12, and the other amplifier.
