XLR Connectors
Each DLM loudspeaker has two female XLR/TRS
combo inputs. Be sure the cables are wired per AES
(Audio Engineering Society) standards:
XLR
Pin 1 – Shield (Ground)
Pin 2 – Hot (+)
Pin 3 – Cold (–)
There is also a male XLR output on each DLM
loudspeaker labeled “THRU”. This is also wired
according to the AES standards listed above.
DLM loudspeakers may be daisy-chained via the male
XLR connector labeled “THRU”. Simply plug the signal
source (i.e., mixer output) into the input jack(s),
and patch that loudspeaker’s THRU jack to the next
loudspeaker’s input jack, and so on, daisy-chaining
multiple DLM loudspeakers. See page 8 for a visual
representation of daisy-chaining.
The THRU jack on DLM loudspeakers are fully
buffered with 100 balanced output impedance
drivers, so there is no additional loading to the inputs
when daisy-chaining. In other words, you could
conceivably daisy-chain DLM loudspeakers indefinitely.

1/4" TRS Connectors
TRS stands for Tip-Ring-Sleeve, the three connections
available on a stereo 1/4" cable. This allows for a
direct connection to the channel 1 and 2 input jacks
on DLM loudspeakers. Hi-Z instruments – guitar, for
example – may be connected directly to the channel 2
input without needing a DI box.
RCA Connectors
RCA-type plugs (also known as phono plugs)
and jacks are often used in home stereo and video
equipment and in many other applications. RCA plugs
are unbalanced. Connect the signal to the center post
and the ground (earth) or shield to the surrounding
“basket.”
