XLR Connectors
Each DLM12S subwoofer has two female XLR
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 are also four male balanced XLR output
connectors on each DLM12S subwoofer [2 high pass
and 2 full range]. These are also wired according
to the AES standards listed above.
DLM12S subwoofers may be daisy-chained via the
male XLR connector labeled “FULL RANGE”. Simply
plug the signal source (i.e., mixer output) into the
input jack(s), and patch that subwoofer’s full range
jack to the next subwoofers’s input jack, and so on,
daisy-chaining multiple DLM12S subwoofers. See
page 7 for a visual representation of daisy-chaining.
The full range jacks on DLM12S subwoofers 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 subwoofers indefinitely.
