Additional Connectors
Locations
Two spare connector locations are provid-
ed on the Model 215’s back panel. They
are labeled A and B. From the factory they
contain blank plates that can be readily
removed and replaced with a variety of
“XLR style” connectors. The spare con-
nector locations are specifically included
so that a Model 215 can be customized to
meet the many specific needs that arise in
broadcast and related audio applications.
Expected uses for these locations include
adding a 6- or 7-pin XLR connector to
allow direct connection of a broadcast
headset. Other uses include creating a
“loop through” or “mult” function for the
microphone input or headphone output
connections. A number of interface cable
assemblies, along with some special
function kits, are available from Studio
Technologies. Please refer to the website
for details on what is available.
The spare connector locations are com-
patible with the Neutrik DL-series of con-
nectors. For flexibility, XLR versions are
available that provide from three to seven
contacts. For example, a compatible 3-pin
female connector would be Neutrik part
number NC3FD-L-1. The NC6FDS-L-1 is
often used to support headsets. This is a
6-pin female connector with the unique
Switchcraft® 6-pin arrangement. Other
connectors, such as the etherCON pro-
tected RJ45 and 3-conductor ¼-inch jack,
can be also be installed. The 4-40 thread-
pitch hardware that secures the blank
plates to the Model 215’s back panel are
also intended to secure the replacement
connectors.
If connectors are added to the Model
215’s spare connector locations adding
labels to them can be helpful. For a great
look it is recommended that Brother®
P-Touch ¼-inch (6 mm) labels be created.
Tape material that prints white text on a
black background works out well for the
Model 215. The Brother label cassette
number TX-3151, white on black, is appro-
priate for use with many of their printers.
The Model 215’s enclosure must be dis-
assembled prior to installing connectors
in the spare locations. Four 6-32 button-
head machine screws, two on the bottom
front of the enclosure and two on the back
panel, must be removed. A 5/64-inch hex
driver is required. The cover can then
be carefully separated from the chassis,
remaining attached by means of a flexible
cable assembly. This “flex-cable” assem-
bly links the main printed circuit board
assembly with the board assembly that
contains the pushbutton switches and
LED indicators. Ensure that the flex cable
is not damaged while the Model 215 is
being customized.
3-Position Headers
In addition to the spare connector loca-
tions on the back panel, provision has
been made to allow easy interconnection
with the Model 215’s printed-circuit-board-
mounted input and output connectors.
This was accomplished by including sev-
eral 3-position male “header” connectors
on the Model 215’s circuit board. These
headers, on 0.1-inch centers, are wired in
parallel with some of the Model 215’s con-
nectors. This “no solder” solution makes
customizing a Model 215 a simple pro-
cess. The headers, located on the Model
215’s printed circuit board, are Molex®
part number 22-23-2031. They mate with
Molex housing number 22-01-3037. To
make the interconnection, separate crimp
