Installation
In this section signal interconnections will
be made using the connectors located
on the back panel of the Model 216. A
microphone 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 con-
nection will be made using either a stan-
dard RJ45 patch cable or an etherCON
protected RJ45 plug. A 4-pin XLR connec-
tor allows the connection of an external
source of 12 volts DC.
System Components
Included in the shipping carton are the fol-
lowing: Model 216 Announcer’s Console,
user guide, and pushbutton label sheet.
If the installation or specific application
requires an external source of 12 volts DC
it needs to be provided separately. An ap-
plicable power supply, the Studio Technol-
ogies PS-DC-02, is available as an option.
Microphone Input
The Model 216 is compatible with bal-
anced dynamic and condenser micro-
phones. Depending on the application,
the microphone may be part of a headset
or be an independent handheld or stand-
mounted model. The Model 216’s P48
power source will support essentially all
phantom-powered microphones. The
quality of the Model 216’s microphone
preamplifier and associated circuitry is
such that special applications may ben-
efit from using “high-end” microphones.
If selected appropriately models from
manufacturers such as AKG, Beyer, DPA,
Sennheiser, and Shure will perform very
well in Model 216 applications.
Microphone interconnection is made by
way of a 3-pin female XLR connector
which is located on the Model 216’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 connec-
tor (male) should be wired so that pin 2
is signal high (+ or hot), and signal com-
mon/shield is connected to both pins 1
and 3.
As of the writing date of this guide, the
Sennheiser HMD 26 and HMD 27 head-
sets are very popular for on-air sports
broadcasting use. Fine products, they
work very well with the Model 216. Adding
the suffix “-XQ” to the headsets’ full part
number specifies a 3-pin male XLR con-
nector for the dynamic microphone and
a ¼-inch 3-conductor plug for the stereo
headphones. This configuration is very
useful, allowing the headsets to work di-
rectly “out of the box” with the Model 216.
Another headset that users have reported
being satisfied with is the audio-technica
BPHS1. Offered at a lower price-point, it
may be applicable for some applications.
If the writer may digress for a moment to
recount 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, pur-
chased only premium-quality headsets,
their total cost of ownership would have
been much less. Enough said…
