Installation/Connection

Installation

The EMX660 uses a forced cooling system with intake on the bottom of the rear panel and exhaust on the top
of the rear panel to avoid blocking the heated air flow.

Connection

When connecting various devices, be sure to use cables and plugs of the appropriate standard.
Speaker connection
There are three ways in which speakers can be connected to the EMX660.
1
Two-channel connection — A single speaker each can be connected to either the A or the B jack of POWER
AMP 1 and of POWER AMP 2.
2
Two-channel parallel connection — Two speakers can be connected in parallel to both the A and B jacks of
POWER AMP 1 and of POWER AMP 2.
3
Bridge connection — A single speaker can be connected to the BRIDGE jack.
For each of these, the required speaker impedance will differ. Refer to the following diagram, and make sure
that the speaker impedance is not less than the specified value.
