200-Series should be reviewed. Complete

Technologies website.
Installation
In this section signal interconnections will
be made using the connectors located on
the back panel of the Model 215. A micro-
phone signal will be interfaced by way of a
3-pin XLR connector. A ¼-inch 3-conductor
phone jack is provided for the headphone
output. An Ethernet data connection will be
made using either a standard RJ45 patch
cable or an etherCON protected RJ45 plug.
A 4-pin XLR connector allows the connec-
tion of an external source of 12 volts DC.
System Components
Included in the shipping carton are the fol-
lowing: Model 215 Announcer’s Console,
user guide, and pushbutton label sheet.
If the installation or specific application re-
quires an external source of 12 volts DC
it needs to be provided separately. An ap-
plicable power supply, the Studio Technolo-
gies PS-DC-02, is available as an option.
Microphone Input
The Model 215 is compatible with balanced
dynamic and condenser microphones. De-
pending on the application, the microphone
may be part of a headset or be an indepen-
dent handheld or stand-mounted model.
The Model 215’s P48 power source will sup-
port essentially all phantom-powered mi-
crophones. The quality of the Model 215’s
microphone preamplifier and associated
circuitry is such that special applications
may benefit from using “high-end” micro-
phones. If selected appropriately models
from manufacturers such as AKG, Beyer,
DPA, Sennheiser, and Shure will perform
very well in Model 215 applications.
Microphone interconnection is made by way
of a 3-pin female XLR connector which is
located on the Model 215’s back panel. The
mating connector (male) should be wired
so that pin 2 is signal high (+ or hot), pin 3
is signal low (– or cold), and pin 1 is shield.
It’s possible that an unbalanced microphone
will also work correctly. In this case, the
mating connector (male) should be wired
so that pin 2 is signal high (+ or hot), and
signal common/shield is connected to both
pins 1 and 3.
As of the writing date of this guide, the
Sennheiser HMD 26 and HMD 27 headsets
are very popular for on-air sports broadcast-
ing use. Fine products, they work very well
with the Model 215. Adding the suffix “-XQ”
to the headsets’ full part number specifies a
3-pin male XLR connector for the dynamic
microphone and a ¼-inch 3-conductor plug
for the stereo headphones. This configura-
tion is very useful, allowing the headsets to
work directly “out of the box” with the Model
215. Another headset that users have re-
ported being satisfied with is the audio-tech-
nica BPHS1. Offered at a lower price-point,
it may be applicable for some applications.
If the writer may digress for a moment to re-
count a story… an audio dealer once shared
a secret with me concerning headsets. He
loved selling the “lower-end” (much less
expensive) models of name-brand headsets,
which he did by the veritable “boatload.”
Why? Because these usually broke soon
after going into service! He knew that on a
regular basis he’d receive orders for more of
them. Had these users, from the beginning,
purchased only premium-quality headsets,
their total cost of ownership would have
been much less. Enough said…
