CONNECTIONS
To ensure quality sound and minimum power
loss, the speaker cable needs to have a large
enough cross section depending on the cable
length, number of speakers per channel and
speaker impedance. The total impedance for a
number of speakers in parallel is equal to the
impedance of one divided by the number of
speakers. For instance, two
in parallel
total 4 ohms (8 ohms divided by 2 boxes equal 4).
It is particularly important to use a large enough
gauge with those speakers that carry deep bass,
such as
, o .
The tables show the minimum size for different
runs of cable and four or eight ohms connected
per channel:

Wiring
Reference series enclosures utilize two NL4
(four pin) Neutrik Speakon connectors. These
connectors are specific for speaker use and allow
a safe and professional connection. For plugging
into an enclosure, insert the male connector into
any of the inputs and rotate it clockwise. It will
then lock into place and be ready for use.
The drawing illustrates the terminal
arrangement detail:
The enclosures provide two paralleled
connectors. This allows for easy loop through from
one speaker to the next. Unused connector pins
are also paralleled. Both connectors can be used
as either inputs or outputs.
