Speaker connections (XM4180/XM4080)

Speakers can be connected to the amplifier in two ways, as shown below. Note that speaker impedance will vary according to
the connection method and the number of speakers. Please be sure that your speaker’s impedance is not less than the relevant
minimum value indicated below.

When connecting high-impedance speakers in parallel (XM4180 only)

XM4180 enables you to connect in parallel fashion multiple high-impedance speakers that support 70V line output. The
number of speakers that can be connected varies depending on the rated input of the speakers. The XM4180 can be con-
nected to speakers with a total rated input of up to 300 W. For example, if you connect ten speakers with a rated input of 5 W
(50 W), ten speakers with a rated input of 10 W (100 W) and ten speakers with a rated input of 15 W (150 W), the amplifier
can be used with a total rated speaker input of 300 W as shown below:

Be sure to use speakers that support the XM4180’s line-out voltage of 70 V.
