System Notes
Our Genesis ULTRA Music System has a number of new features that
need to be fully understood to use this system to it’s full potential
•Music provides comfort to the patient during the procedure
•Our yoke style headsets attenuate gradient noise to patient’s ears by 26.7 dB
•DSP technology provides the highest sound quality available for the patient
•Active volume compensation (Auto Gain) changes volume automatically to 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, multi-disc CD changer
•Built in interface for intercom integration all GE MRIs
•Built in interface for fMRI

Headset Operation
Ea r Ca na l
Ea r Tip Ea r
Please Note the tops of the Headset rotate
In order to provide the highest level of attenuation it is necessary to first, rotate
tops of Headset toward the rear of the patients’ head, then while applying
pressure rotate fully forward to align with the ear canal as pictured above.
It is highly recommended that technologists experiment on
themselves to get a feel for this operation.

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 Violet 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 Blue PAT OVERRIDE button (located above the MIC button) will toggle
thru locking out the patient from adjusting the VOL, SEL, VOLSEL, or OFF. This will also
be displayed on the lower right “PAT OVR” box.
7: We recommend getting in the habit of depressing the Blue 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 Green MUSIC VOL- button (located above the VOL NORM button) will lower
Volume for the Patients, and depressing the 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.

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 Violet 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 Violet COMP button (located under the Violet 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 and Violet
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 6 for visual reference of
button locations)

29: There are very sensitive pressure switches located in the Transducer if pressure builds up even
due to a temperature differential the switches might activate causing the volume to go up or
down, or music selections to change on there own with no input from the patient. Therefore it is
good practice to let the Controls and Transducer sit for a few hours at Scan Room temperature
then follow the vent procedure below. Vent the Patient Volume Control and Patient Selection
Controls to the atmosphere by pulling the tubing from the nipples on the Transducer one pair at
a time (observing polarity for proper synchronization). This also corrects for vacuum or pressure
built up from shipping.
30: Connect Gradient noise sensing Mic to the BNC connection on the side of Transducer. Place
Mic near the front of the bore. Secure with mounting pad and zip tie.
31: Connect the clear Siamese Headset tubing to the large brass tubes protruding from the top of

CAUTION Ensure that all connections are complete before connecting AC power
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 pull AC Power and contact Magnacoustics Tech Support at 1-
36: Press the green Power Button on the TCU a self-test should complete and the system should
power up in Tuner mode. (It may be necessary to adjust the FM antenna to get better reception.
Keep in mind that if the MRI is located in the basement or with most of the transmitting Radio
stations separated by the Scan Room, some form of external antenna might be required).
37: After making sure the Stereo is playing ok (with Tuner, Tape 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 Blue MIC button have them speak into the MIC and
ensure you can hear them loud and clear.)
38: In order to set the AUTO GAIN it will be necessary Program the ambient and Full Scan Sound
Pressure Levels into the Microprocessor. Depress the PROGRAM button once; depress the
MUSIC VOL- button to toggle down till Ambient MIC SET is highlighted. Then depress the
INPUT/ENTER button once and then again allowing the Auto Gain Mic to capture and record the
(Sound Pressure Level) in the room with the scanner idle. Then depress the MUSIC VOL- once
to highlight LOUD MIC SET depress the INPUT/ENTER once, set up a Phantom and start the
Scanner for and average scan, then depress the INPUT/ENTER one more time to capture and
record the (Sound Pressure Level) of an average Scanner. Then depress the PROGRAM once
(which will store the two extremes) and let the Microprocessor calculate when and how much
Auto Gain in necessary.
