A.1. SAFETY CONDITIONS
After removing any housing parts and electronic assemblies it’s
possible to get access to live parts. It‘s essential to ensure that the
subsequent safety rules are strictly observed:
Servicing of electronic equipment must be performed by qualified
personnel only.
Before removing covers the equipment has to be switched off and the
mains cable unplugged.
When the equipment is open power supply capacitors have to be
discharged with the help of a suitable resistor.
When the equipment is open components, that carry havy electrical
loads, such as power transistors and resistors as well as solenoid
coils should not be touched before a cooling off interval, as a
precaution to avoid burns.
During servicing unprotected and operating equipment never touch
bare wires or circuitry.
During servicing unprotected and operating equipment use insulated
tools only.
During servicing unprotected and operating equipment never touch
metal semiconductor cases because they may carry high voltages.
For removing and installing electronic components, please follow the
recommandations concerning the handling of MOS components.
A. INSTALLATION INSTRUCTIONS
USER`S MANUAL ME-TUN
File: ME-TUN Manual E.DOC MEDIA ENGINEERING page 6/29
A.1.1. ELECTROMAGNETICAL INTERFERENCE
In case the ME-TUN is installed and operated in a strongly electromagnetical disturbed
environment, signals of interferences can occur during reception of the FM Band.
A.1.2. ENVIRONMENT TEMPERATURE
Preferably install the equipment in a dry location with approximately 20 centigrades (room
temperature) of ambient temperature. The ambient temperature has a large influence on the
contrast of the LCD display.
A.1.3. CAUTION WITH THE MAINS CABLE
Always seize the mains cable at the plug. Do not pull on the cable and never touch the
mains cable with wet hands, since this can cause a short-circuit or an electrical shock. Do
not place equipment or a furniture on the mains cable. A damaged mains cable can cause
fire or an electrical shock. Therefore examine the mains cable occasionally. Should it be
damaged, get in contact with your next customer service in order to replace the cable.
A.1.4. DO NOT REMOVE COVER
To prevent electric shock, do not remove the cover. There are no user serviceable parts
inside the ME-TUN. Refer servicing to qualified service personnel only.
USER`S MANUAL ME-TUN

A.2. INSTALLATION PROCEDURE
Place the ME-TUN professional FM tuner in a horizontal position, and do not place anything
heavy on it. Never bring a magnet or magnetized objects near the tuner, because such will
adversely affect the performance of the ME-TUN.
Should it be necessary to change the sampling rate of the digital audio output to another
value than the factory set 48kHz please refer to chapter A3.
In case the ME-TUN has to be installed in a 19” rack the appropriate 19” brackets have to be
mounted first in order to convert the table top device into a rack mountable device:
a) loosen the two black M4 screws on the left and right side of the ME-TUN with the help
of an appropriate 2.5mm PHILIPS screw driver
b) put the two screws beside for they will be used again at the end
c) unpack the two blue 19” brackets that are delivered as an add-on to every ME-TUN
d) with a little movement from back to forward the brackets can be hooked into place
while the U-shaped end of the bracket is grabbing around the end of the side wall.
e) carefully replace the M4 screws from the left hand side rsp. from the right hand side
and tighten them slightly (“two finger” torque)
It’s a good rule of practice to mount at least a 19”/1RU blank panel on top and below each
19” rack mountable device. The same is true for the ME-TUN and - whenever possible - a
blank panel above and below each ME-TUN should be mounted.

A.3. SETTING THE SAMPLING RATE FOR THE DIGITAL AUDIO OUTPUT
The AES/EBU digital audio output on the rear side of the ME-TUN is featuring a sampling
rate of 48kHz. This sampling rate is factory set and marked on the rear panel as such.
In case this is not the propre sampling rate for a given application it’s possible to choose one
of three other values:
• 32 kHz
• 44.1 kHz
• 48 kHz
• 96 kHz
In order to change the sampling rate one needs to change the setting of two jumpers which
are located inside the ME-TUN. Please refer to the procedure as described herewith:
1. Carefully study the SAFETY CONDITIONS in chapter A.1. on page 5
2. disconnect all cables from the ME-TUN. Make shure there is no power line
connected anymore and the power switch is off.
3. loosen the three black M3 screws on the top front of the ME-TUN with the
help of an appropriate 2.0mm PHILIPS screw driver in order to remove the
cover.
4. put the three screws beside for they will be used again at the end
5. shift the cover 10mm to the rear and lift it off
6. locate the output amplifier board (called TADOBOARD, 72mm x 132mm) at
the very back totally to the right.
7. loosen the three black M3 screws holding down the output amplifier board
with the help of an appropriate 2.0mm PHILIPS screw driver
8. put the three screws beside for they will be used again at the end
9. with gentle force and a slight left to right rocking unplug and remove the board
in a straight vertical direction
USER`S MANUAL ME-TUN

10. locate the two jumpers J1 and J0 according to the PCB layout drawing:
jumper J1 jumper J0
11. choose the new sampling rate and select the propre jumper setting:
fs J1 J0
96 kHz 00
48kHz 01
44.1 kHz 10
32kHz 11
J1 J0
The table indicates the jumper settings as follows:
- “0” indicates that no jumper has to be set
- “1” indicates that a jumper has to be set
example: in order to set a sampling rate of 48kHz (which is the factory
setting) do not set a jumper at the left position J1 but set a
jumper on the right position J0
USER`S MANUAL ME-TUN
File: ME-TUN Manual E.DOC MEDIA ENGINEERING page 10/29
12. put the output amplifier board back into the ME-TUN. Make shure the 22pin
connector fits right into the socket underneath the cutout in the metallic
shielding. The board is placed perfectly if there shows up an air gap between
the board and the side wall of the ME-TUN of approximately 0.5mm
13. put in place the three black M3 screws in order to hold down the output
amplifier board. Make shure the propre screws with the half spherical head
are used
14. tighten the crews slightly (“two finger” torque) with the help of an appropriate
2.0mm PHILIPS screw driver. DO NOT USE STRENGTH.
15. replace the cover of the ME-TUN in a vertical motion so that there remains
an air gap of approximately 10mm in the front section
16. shift the cover 10mm into the front direction in order to allow the bended
shielding at the back grabing the U shaped rear side.
17. put in place the three black M3 screws in order to hold down the cover. Make
shure the propre screws are used so that they can be lowered into the cover
in order to achieve a totally flat surface.
18. reinstall the ME-TUN.
19. check your application with the new setting of the sampling rate. If it doesn’t
work properly one of the following problems might have occurred:
Öthe output amplifier boards 22pin connector is not properly
connected to the socket and there is not a 0.5mm air gap on
the right side of the board. Solution: go back to point 11.
Öthe jumper setting is wrong. Solution: go back to point 10 and
make shure that a “0” indicates no jumper but a “1” indicates
a jumper. J1 is the left and J0 is the right jumper.
Öthe jumper setting is not matching the features of your external
device (e.g. a mixing console). Solution: check if your external
device is able to handle one of the four selectable sampling
rates and then choose one of these.
