EMX66M—Owner’s Manual
Installation/Connection
Installation
The EMX66M 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.
Use dedicated speaker cables to connect the speakers to the speaker jacks.
Speaker connection
There are three ways in which speakers can be connected to the EMX66M.
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-MON or MAIN-MAIN:
• Two-channel connection
Two 4-8Ω speakers can be connected to either SPEAKERS jack 1 or jack 2 of channels A and B. If you are
using speakers rated at 4Ω, the maximum output would be 300W + 300W.
• Two-channel parallel connection
Two 8-16Ω speakers can be connected to both SPEAKERS jack 1 and jack 2 of channels A and B. If you are
using speakers rated at 8Ω, the maximum output would be 300W + 300W.
