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 EMX640; a single speaker each can be con-
nected to either the A or the B jack of POWER AMP 1 and of POWER AMP 2, two speakers can be connected
in parallel to both the A and B jacks of POWER AMP 1 and of POWER AMP 2, or a single speaker can be con-
nected to the BRIDGE jack (bridge connection). 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.
