SYSTEMOVERVIEW
The MRIaudioPREM-1001 & 1001 Patient Stereo is a pneumatic audio system composed of both MRI-
safe and MRI-unsafe components.
It is critically important that only MRI-safe and MRI-conditional components be taken into and
installed in the MRI suite.
When installed correctly, the MRIaudioPREM-1000 & 1001 system is MRI-compatible and will produce
high quality audio for patients undergoing MRI scans.

Clear a convenient space for the amplifier and components on or near the
technologist desk.
Technologists will want easy
access to:
- Digital Amplifier controls
- Shure Microphone
- Tech speakers
- iPad
INSTALLATIONGUIDE
STEP 1 – ASSEMBLE COMPONENTS IN THE CONTROL ROOM
Begin in the technologist control room by setting up the amplifier and plugging
the technologist speakers, Shure 450 series microphone, and 3.5mm to RCA cable
into their respective ports.

Locate the 100ft coaxial cable and “place it” in the computer room (ensure it is
NOT the 45ft RF shielded cable). The exposed small red and black pig tail
cables will ultimately connect to the back of the amplifier at ZONE 1 AMP OUT.
INSTALLATIONGUIDE
STEP 2 – RUNNING THE CABLES
NOTE: Be aware STEP 2 through STEP 3 will overview two different
kits. Make sure you fallow procedure according to your kit number.
MRIaudioPREM-1000 uses cables: 211, 203, 202 (BNC ONLY)
MRIaudioPREM-1001 uses cables: 210, 201 (DB9 ONLY)
Steps 2.1 through 2.4 will demonstrate how to run the 100ft coaxial cable from the
technologists desk to the penetration panel. Use the “racetrack” cable trough or ceiling
tiles outside the RF-shielded MR suite.
This is often the most difficult step in the installation and it can be helpful to have
two people for this stage to help feed and retrieve the cables and/or fish tape.
FOR FACILITIES WITH AN EXISTING PATIENT STEREO:
Check to see if the old system used a 9-Pin D-sub or a BNC connection.
For customers with existing Magnacoustics system: You have the option to remove
this cable, and it can be helpful for pulling your new 100’ DB9 cable through (to avoid
running fish tape).
a. Unplug the 9-Pin D-sub from the penetration panel and patient stereo.
b. Continue to step 2.3 by affixing the ends of the old 9-pin and new cable rather than
using fish tape. (Note: Use fish tape if you prefer or if the 9-pin wire is compromised.)
c. Tie the two ends together and wrap the connection with electrical tape to secure
the connection, protect the adapters, and smooth the joint (to avoid snagging during
the pull).

Starting at the technologist desk, feed the fish tape through the cable
trough or above the ceiling tiles until it reaches the penetration panel.
Inside the computer room, attach the “pigtail” (red and black end) of cable to
the fish tape so it will not detach midway through the pull. Pull the pigtail end
of the cable through to the technologist desk. Ensure the “DB9 or BNC” side of
the cable remains in the computer room, as it is ultimately attached to the
penetration panel.

Attach the 45’ RF Shielded Cable to the DB9 or BNC ports located on the MRI
suite penetration panel. Use the adjacent DB9 or BNC ports from step 2.4.
Run the 45ft RF Shielded cable to the foot of the magnet along the floor or
through the ceiling.
For aesthetics, you may run the wire using a conduit cable cover or inside the
MRI shell, depending on the age of the magnet.
INSTALLATIONGUIDE
STEP 2 – CONTINUED
Connect the DB9 connector to the
penetration panel in the computer room.
Be sure to record which DB9 port you use.
This will help with connecting to
the DB9 port in the MRI suite.
NOTE: Use J16, J17 or J18.
Record selected DB9 Port:
________
If using a 100’ BNC coaxial cable
you will have to use a Y splitter part # 211.
1.
Connect the female BNC on the Y-Splitter
to the male BNC on the coaxial cable.
2.
Connect the Y splitter to two
available BNC ports on the
computer room penetration panel.
Record selected BNC Ports:
________ ________

STEP 3 – ASSEMBLE COMPONENTS INSIDE THE MRI SUITE
Be sure to remove all ferrous items from your person before entering the MRI Suite!
Continue assembly by installing the 45’ RF Shielded Cable, transducer and pneumatic tubing.
With 3G Transducer, exercise extreme caution until transducer is mounted and
secured successfully. Magnetic pull near bore of magnet can be significant!

WARNING! 3G Transducer is
MR conditional keep 3’ from
the bore at all times.
Option 1:
One of the most common areas to
mount the transducer is to the front
left or right side of the MRI; as seen
illustration to the right.
Be sure to clean floor space with
alcohol or another non-oil
based cleaner.
Option 2:
Remove the lower side panels on
the desired placement side of the
MRI and secure the transducer
using the included mount
underneath the magnet; when
adhering the transducer, be sure
to clean floor space with alcohol
or another non-oil based cleaner.
Plug the RF Shielded BNC cable into
the side of the transducer.
3.3
INSTALLATIONGUIDE
STEP 3 – CONTINUED
Insert the male end of the pneumatic
tubing into the top coupling of the
transducer.
Make sure the connector is fully inserted
to achieve the highest sound quality.
3.4
Check to ensure there are no coils in the RF shielded cable. Coils in the
pneumatic tube are MRI safe.
Coils in the RF shielded cable are not MRI-
safe.
Remove any coils present within the MRI suite by feeding cable slack
toward the penetration panel.
3.5
Once the slack is condensed at the penetration
panel, flatten and zip-tie it to aid cable
organization. Be sure to leave enough
slack to adjust the transducer as needed.
Never coil excess cable in MRI suite.

INSTALLATIONGUIDE
STEP 4 – FINAL ASSEMBLY, TESTING AND TROUBLE SHOOTING
Plug the amplifier power cord into the power strip
located inside the PC console (reference system
map above) and ensure power is running to the
amplifier by checking that the blue light in the
bottom right corner is illuminated. After inserting
the power cord into the amplifier make sure to
twist and lock the power cord in place.
When connecting to a Siemens MRI use the wall outlet.
4.2
Ensure the system is operating correctly by testing all media sources
(iPad / Microphone), as well as the headphones and technologist speakers.
