Appendix B: Connections

Balanced XLR Input Connector
Each SRM loudspeaker has two female XLR/TRS/TS
combo inputs. Be sure the cables are wired per
AES (Audio Engineering Society) standards:
Balanced XLR Input Connector
Pin 1 – Shield (Ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
Balanced XLR Input Connector
Balanced XLR Output Connector
There is also a male XLR output on each SRM
loudspeaker labeled "THRU". Be sure the cables are
wired per AES (Audio Engineering Society) standards:
Balanced XLR Output Connector
Pin 1 – Shield (Ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
Balanced XLR Output Connector
SRM 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 SRM loudspeakers. See page 7 for a visual
representation of daisy-chaining.

Balanced 1/4" TRS Connector
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 SRM loudspeakers. Be sure the cables are wired per
AES (Audio Engineering Society) standards:

Sleeve – Shield (Ground)
Tip – Positive (+ or hot)
Ring – Negative (– or cold)

Unbalanced 1/4" TS Connector
TS stands for Tip-Sleeve, the two connections
available on a mono 1/4" cable. This allows for a
direct connection to the channel 1 and 2 input
jacks on SRM loudspeakers. Be sure the cables are
wired per AES (Audio Engineering Society) standards:
Unbalanced 1/4" TS Connector
Sleeve – Shield (Ground)
Tip – Positive (+ or hot)
Unbalanced 1/4" TS Connector
Unbalanced RCA Connector
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." Be sure the cables are wired per AES (Audio
Engineering Society) standards:
