System Notes
Our Genesis ULTRA Music System has a number features that need to be fully
understood to use this system to its full potential
Music provides comfort to the patient during the procedure.
Our MagnaLink™ Pneumatic Stethoscope Style Headsets attenuate gradient noise to patient’s
ears by 30dB (NRR) Tested per ANSI standard and comply with the GEHC MR Operators Guide.
DSP technology provides the highest sound quality available for the patient.
Active volume compensation (Auto Gain) changes volume automatically to help mask MR gradient
sounds.
Patient volume and music selection controls with voice feedback for maximum comfort and
versatility.
Backlit Technologist Control Unit allows operation of the entire system with a touch of the button,
even in low-light environments.
Built-in intercom allows the Technologist to communicate directly with the patient even while the
scan is in progress.
Complete AM-FM stereo, CD and iPod interface.
Built-in interface for AutoVoice and intercom integration all GE MRIs.
Built-in Patient Ready Signal (PRS) to signal patients’ readiness for the scan to begin.
Built-in interface for fMRI.
Built-in interface audio portion of Video.
100 % Microprocessor controlled which simplifies operation and programming.
MagnaLink™ Headset & MagnaPlug™ Instructions
The MagnaLink™ System provides the patient with 30dB of attenuation (NRR) tested per ANSI
standard and complies with GE Healthcare’s MR Safety Guide Operator Manual, Revision 7
requirements.
Because your MRI can produce sound pressure levels that may cause hearing damage, GE
Healthcare requires that the Technologist ensure a proper fit of all hearing protection devices.
Please refer to the detailed instructions below. This procedure will take less than 1 minute to
accomplish, assuming the headsets and consumables are readily available and in close proximity
to the gantry.
Magnacoustics Inc™ © 3/2010 rev- j 4|

1. There are two sizes of
MagnaPlugs available:
MagnaPlug .75” X .50” for
average size ear canals
MagnaPlug Mini .75” X .38”
for smaller than average size
ear canals
2. The MagnaLink™ “Yoke” will
provide a small amount of
tension to maintain the
MagnaLink to MagnaPlug to
patient ear canal connection.
3. The MagnaLink couplers
rotate to facilitate alignment
of MagnaPlugs with the
patient’s ear canals.
4. Please identify what size
MagnaPlug is required for the
patient and then insert them
into the MagnaLink couplers.
5. Hold the MagnaLink headset
in your hands. Using your
thumbs and first fingers gently
start rolling, gradually
increasing pressure.
6. Roll until you reach the
smallest diameter possible.
Avoid pinching.
MagnaLink™ Headset & MagnaPlug™ Instructions
10. There is a very good and informative YouTube Video titled “Fitting Foam Earplugs”. Please review
for help with the proper technique for the insertion of foam earplugs into the ear canal.
http://www.youtube.com/watch?v=MvG5oVW6FCo
Caution:
1. Only use the Magnacoustics MagnaLink™ System with your Magnacoustics Music System.
This will ensure your patients hearing protection with all coils in addition to allowing your system to
meet and/or exceed GE Healthcare’s attenuation requirements.
2. Use of any other headset with your Magnacoustics MRI Music System will NOT work and may
cause serious patient safety issues.
3. The Magnacoustics MagnaLink™ System was designed for Magnacoustics MRI Music Systems
Only. Use on other non-Magnacoustics Systems may cause serious patient safety issues.
Magnacoustics Inc™ © 3/2010 rev – j 5|
7. Insert one side of the headset
at a time into the patient’s
ears. (Best done when the
patient is in the supine
position)
8. Hold in place or instruct the
patient to hold for about 15 to
20 seconds so that the
MagnaPlugs can fully re-
expand.
9. After the scan is completed,
discard the MagnaPlugs. Do
not attempt to reuse them, they
are a disposable item. Ear
infections are spread very
easily.

Technologist Control Unit Operation
Terminology: TCU = Technologist Control Unit
1: To turn Genesis MRI Music ON from TCU push the Green Power button (located on the top right
corner).
2: To adjust Technologist’s Speaker Music Level depress the Green TECH VOL+ and the Red
VOL– (located to the left of the Power button) for UP and Down respectively. The Stereo will
show the level. To Mute the Technologist’s Speakers depress the Violet TECH MUTE button
(located under the Red VOL- button). The “ON” will flash on the mid right side of the display in the
MUTE box.
3: On power up the microprocessor sets VOL, Mic, and AVC level for patients wherever it was left
when the system was turned off. The number equals the percentage of volume and the horizontal
bar gives a quick visual representation.
4: Depressing the Green Mic button (located on bottom left corner) will allow you to override music
and talk to the patients. Level can be adjusted buy depressing Green Mic VOL+, or the Red
VOL-, for UP and Down respectively. A good starting point is 50. When Mic button is depressed
you will see “Mic” on the lower left “MODE” box of the display.
5: When the AVC (intercom integration) input has triggered from depressing the Mic button on
your GE Intercom (providing the intercom integration kit was installed) the Display will show AVC
in the lower left “MODE” box, and the music to the patient will be interrupted. The AVC level and
the console intercom level will control the level to the patients (it’s a good idea adjust the AVC
and, leave the console set the same for a Patient without Headsets.) A good starting point is 50
but no two MRIs are the same.
6: Depressing the Red PAT OVERRIDE button (located above the Mic button) will toggle thru
locking out the patient from adjusting the VOL, SEL, VOL SEL, or OFF. This will also be
displayed on the lower right “PAT OVR” box.
7: We recommend getting in the habit of depressing the Red PAT MUTE button (located above PAT
OVERRIDE button) after each patient (this way when you are setting up a new patient they will be
able to hear you, if the music is on they probably can’t.)
8: Depressing the Green VOL NORM button (located above VOL OFF button) will raise Volume for
the Patients to 20. This preset is a good starting point and can be adjusted in program mode
described in step 14.
9: Depressing Red MUSIC VOL- button (located above the VOL NORM button) will lower Volume
for the Patients, and depressing the Green MUSIC VOL+ (located above the MUSIC VOL-
button) will raise Volume for the Patients.
10: The Genesis has a feature called AUTO GAIN this provides the ability to automatically adjust
volume level of music to Patients dependent on the amount gradient noise being created by MRI.
Magnacoustics Inc™ © 3/2010 rev – j 7|
Technologist Control Unit Operation
11: Depending on how loud the Scan Sequence is the AUTO GAIN can be turned on and off by
depressing the Blue AUTO GAIN button (located under the Red Mic VOL- button). The AUTO
GAIN setting can be seen on the upper left corner of the display in the “GAIN” box (Off, Idle,
Low, Med, and High). When the AUTO GAIN is active you can also see an ^ to the left of the
VOL BAR indicating that it has adjusted the MUSIC LEVEL to the Patient. The percentage can
be adjusted to 5%, 10%, 15%, 20%, or 25% per stage in the PROGRAM MODE STEP 14.
12: Depressing the Blue COMP button (located under the Blue AUTO GAIN button) will provide a
more even flow of Music to the Patient, by raising the lows and lowering the highs.
13: All the other buttons control the Stereo.
14: Depressing the Blue “PROGRAM” button (located below the red AVC VOL- button) will put the
system in “Program Mode. Depressing the MUSIC VOL+ and VOL- button toggle up and down
through the Menu respectively. Depressing the Blue / Green INPUT/ENTER button (located
bellow the Blue PROGRAM button) will toggle the options in the menu that is highlighted.
Depressing the PROGRAM button again will memorize any changes you have made and exit the
Program Mode. (Use Page 8 for visual reference of button locations)

Genesis ULTRA Installation and Connections - continued
27: Leave approximately 18” of cable “CB2” protruding from the front center of the MRI directly
above the table docking mechanism for a service loop, or alongside the base of the gantry.
It is important to locate the end of “CB2” as close as possible to the front center of the
bore.
28: For all MRI’s it is very important to locate the Transducer as close as possible to the front
center of the bore. For all GE MRI’s locate the Transducer either side of the pedestal
above the Up / Down height control peddles as pictured below. Connect cable “CB2” to
the Transducer.
29: There are very sensitive pressure actuated switches for the patient controls located in the
Transducer. During shipping sometimes pressure or vacuums can build in the controls
causing erroneous operation of the patient volume and mode selection buttons. Therefore
it is good practice to let the Controls and Transducer become acclimated to the scan room
environment for a few hours or until the temperature stabilizes then;
a. Vent the patient controls to the atmosphere by momentarily removing the white tubing
one pair at a time and reconnecting them to the nipples on the Transducer observing
polarity for proper synchronization.
30: Insure that the Gradient noise sensing Mic is connected to the BNC connection on the side
of Transducer. Place the Mic anywhere in the general area. Secure with the provided
mounting pad and zip tie.
31: Connect the clear Siamese Headset tubing to the brass tubes protruding from the top of
Transducer. Do not add any additional tubing length to this system, doing so will
adversely affect performance and reliability.
32: Connect the Headset to Siamese tubing.
CAUTION: Please ensure that all connections are complete before connecting AC power cord.
33: Connect power cord from Stereo to AC receptacle 120V / 15 Amp minimum.
34: Connect the plug side of “CB8” to AC receptacle 120V / 15 Amp minimum.
35: Look at the front panel of the Genesis and ensure the all-8 red LED’s are lit under Circuit A
Power and Circuit B Power. If not, unplug the AC power cords and contact Magnacoustics
Tech Support at 1-800-637-2282 or E-mail at [email protected] for assistance.

36: Press the green Power Button on the TCU a self-test will complete and the system should
power up in Tuner mode. (It may be necessary to adjust the FM antenna to get better
reception. Please keep in mind that if the MRI is located in the basement or if most of the
transmitting Radio stations are separated by the Scan Room RF Shielding, some form of
auxiliary or external antenna might be required.
37: After making sure the Stereo is playing ok (with Tuner, iPod or CD selected). Depress the
Green VOL NORM button and go into the Scan Room to ensure there is music playing
from the Headsets. (If you have help depress the Green Mic button speak into the
supplied Mic (make sure the Mic mute switch is off) to ensure intercom operation.
Auto Gain Calibration Procedure
38: In order to calibrate the Microprocessor for AUTO GAIN Function it will be necessary to
program the Ambient and Full Scan SPL levels, the please follow this procedure;
a. Depress the Blue PROG MODE button once.
b. Depress the MUSIC VOL- button to toggle down till 11. Ambient MIC Set is highlighted.
c. Depress the INPUT/ENTER button once and then again allowing the Auto Gain Mic to
capture the SPL in the room with the scanner idle.
d. Depress the MUSIC VOL- once to highlight 12. SCAN MIC Level Set depress the

e. Set up a Phantom and start the Scanner for and average scan (Full Scan Level).
f. Depress the INPUT/ENTER one more time to capture the SPL in the room with the
scanner active.
g. Depress the Blue PROG MODE once (which will store the two extremes) and let the
Microprocessor calculate how much Auto Gain in necessary.
CAUTION: Please do not connect any external Antenna or Audio input to the stereo without the
proper isolation. We use the Scan Room Shielding as our ground reference. Any auxiliary
connection to the stereo might not have the same ground potential causing a 60 cycle hum from
the speakers or patient headset. This difference in ground potential my also cause system
damage.
1. Radio Shack Ground Loop Isolator Catalog #: 270-054 with the proper phono to 3.5mm
stereo adapter Radio Shack Catalog #: 274-883 and xx adapter or equivalent must be used.
2. A 75 to 300 ohm adapter in series with the any external antenna source must be used.
