SPEAKER CONNECTION
The XM410's power amplifier section can be configured to operate several ways depending on the setting of
the power amp MODE switch located on the front panel. This allows you to choose whether you need MAIN
plus MONITOR amplifiers to power your speakers, or if you just need more power for the MAIN speakers. For
more information on the power amp MODE switch, see the section POWER AMP SECTION on page 6 of this
manual.
There are three ways in which speakers can be connected to the XM410: A single speaker can be connected to
the output jack of AMP 1 and AMP 2, two speakers can be connected in parallel to output jacks of AMP1 and
AMP 2, or a single speaker can be connected 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.
Additional, or alternative amplifiers can be connected to the MAIN OUT and MONITOR OUT jacks on the front
panel.
When connecting one
speaker to POWER AMP
1 and one speaker to
POWER AMP 2, use speak-
ers with a 4 – 8 ohm
impedance rating.
XM410 Input and Output Connections
When connecting two
speakers to POWER AMP
1 and two speakers to
POWER AMP 2, use speak-
ers with a 8 – 16 ohm
impedance rating.
In this example, each pair of speakers is wired in
Parallel or "daisy-chained" together using the speaker's
Extension Output, so the total impedance when two 8
Ohm speakers are connected is 4 Ohms.

When the POWER AMPS
are in BRIDGE use a
speaker with a 8 – 16 ohm
impedance rating.
