5. Setting Up
5.1 Operating Environment
1.
Acceptable ambient temperature during operation ranges from
-5˚C to +40˚C.
2.
Acceptable temperature during storage or shipping ranges from
-15˚C to +40˚C.
3.
If condensation has formed on the equipment or the rear panel
during shipping or storage, allow the unit to acclimate for 2
hours before powering up.
4.
The loudspeaker has been designed for use in a dry
environment with air of normal relative humidity and dust
concentration. Never expose the unit to aggressive chemical
liquids or vapors.
5.
You can position the unit at any angle. Make sure, though, to
provide at least 4 inches of free air space behind the rear panel
for adequate ventilation.
5.2 Audio Connections
1.
Set all VOLUME controls (8), (12) and to zero.
2.
Connect the desired audio source (e.g., cassette player, CD
player) to the LINE INPUT jacks (6) or (7) using a standard
cable.
3.
Use a commercial XLR cable to connect your wired microphone
to the INPUT connector (16).
4.
If you want to record your performance or presentation,
connect a (cassette, DAT, tape or other) recorder to the LINE
OUT jack (9) using standard jack cable.
5.
For consistent audience coverage, you can use another Direct-
Media. Connect the LINE OUT jack (9) to the LINE IN jack (7)
of the other Direct-Media.
5.3 Powering Up
The Direct-Media has been designed for an AC voltage of 230
V/50Hz. Custom versions with an adapter for other AC voltages are
available on request.
1.
Plug the the supplied AC into the Main Input (1) on the Direct-
Media rear panel.
2.
Check that the AC mains voltage stated on the supplied
AC adapter is identical to the AC mains voltage available
where you will use your Direct-Media. Using the AC adapter
with a different AC voltage may cause irreparable damage to
the unit.
3.
Connect the AC cable on the AC adapter to a convenient power
outlet.
Important:
In case the AC plug needs to be replaced with a
different type, note that this job may only be
performed by a qualified technician.
4.
To power up the Direct-Media set the POWER switch (3) to ON.
The STATUS LED in the POWER switch (3) will illuminate red.

6. Operating Notes
6.1 Optimum Placement
In order to ensure consistent coverage and intelligibility from the
first to the last row of the auditorium,
1.
Place the Direct-Media as high as possible using a loudspeaker
stand.
2.
Check that loudspeaker is clearly visible from each seat or
standing room area and that the sound will not be absorbed by
people or objects.
3.
To optimally align the Direct-Media, you can use the optional
SHM1 stand adapter:
1.
Mount the loudspeaker on the stand adapter.
2.
Place the loudspeakeradapter on the loudspeaker stand.
Extend the stand to its full length and aim the
3.
loudspeaker down at the audience in the same way you
would aim a spot-light to cover the entire audience.
6.2 Avoiding Feedback
When using your Direct-Media with a wired or wireles microphone,
acoustic feedback may occur so the loudspeaker would start
whistling or howling. To prevent feedback:
1.
Make sure the talker will stand behind the loudspeaker in order
to prevent feedback.
2.
Make sure never to point the microphone element directly at
the loudspeaker.
3.
Hold the handheld transmitter by the shaft. Be sure not to
cover the microphone element with your hand.
4.
Should the loudspeaker start whistling or howling at the same
turn the VOLUME control (12) down CCW to the point that the
feedback noise will stop.
7. Cleaning
You can clean the loudspeaker enclosure with a moistened cloth.
Make sure that liquid will not penetrate into the case.
