EMX88S/EMX68S—Owner’s Manual
Connections
When connecting various devices, make sure the cables and plugs have the correct rating.
Be sure to use cables designed for the purpose when you connect speakers to speaker jacks.
■ Connecting main speakers
There are three ways in which speakers can be connected to the EMX88S/EMX68S.
The speaker impedance requirement varies depending on how you connect the speakers. Refer to the dia-
grams below to make sure the speaker impedance will not be lower than the specified value.
■ When the power amp select switch is set to MAIN L-R or MAIN (L+R)-MON:
• 2-channel connections
Connect either one or two speakers each to jacks A and jacks B.
If the power amp select switch is set to MAIN L-R, the signals of the MAIN L and MAIN R buses will be out-
put respectively to the speakers connected to the A and B jacks. If the power amp select switch is set to MAIN
(L+R)-MON, the summed signals of the MAIN L bus + R bus and the signal of the MONITOR bus will be
output respectively to jacks A and B.
For either setting of the switch, use speakers with an impedance in the range of 4–8 ohms if you are connect-
ing only one speaker to each set of outputs. A maximum output of 400W + 400W will be obtained when 4-
ohm speakers are used.
• 2-channel parallel connections
If you connect two speakers to each set of outputs, use speakers with an impedance in the range of 8–16 ohms.
A maximum output of 400W + 400W will be obtained when 8-ohm speakers are used.
