dB Technologies IEM 2200 Bedienungsanleitung Seite 12

Turn up the input level until the indicators operate at 0 dBV at audio peaks. Occasional overloads are acceptable but
please be aware that signals exceeding this level could lead to the sound becoming compressed or "pumped".
Transmitter Monitor
The monitor section of the transmitter allows monitoring of the signal before it is transmitted to the receiver. This
feature is also ideal for use by a performer who wishes to benefit from in ear monitoring but does not require a
wireless link.
The monitor amplifier may be used with in ear molds or "earbud" style earpieces which maybe plugged into either the
¼" or 3.5mm sockets. Regular headphones will also work but please bear in mind that high impedance headphones (
more than 50 Ohms) will operate at a much reduced volume.
The Receiver
To access the battery compartment, slide the battery cover towards the bottom of the beltpack. It will then hinge
around to the right revealing the battery compartment.
Insert a fresh alkaline battery (MN1604 or equivalent) taking care to observe polarity and carefully hinge the cover
back over the battery and then slide it forwards until it clicks into place.
Check the volume control is set to minimum and switch on the receiver. The word "test" will appear momentarily
whilst the IEM2200R receiver carries out its self-testing routines. The LCD will then display the current operating
frequency along with a bargraph to indicate strength of the received signal.
Check the frequency displayed in the LCD is the same as the transmitter (The section Programming explains how to
change the operating frequency)
Now make sure you are within 2 meters of the transmitter and check that the RF signal bargraph is displaying more
than 3 dots. Less than this would indicate poor reception.
If the battery icon is displayed in the LCD, this would indicated low battery voltage. If this is the case, please replace
the battery with a fresh alkaline type. During operation, the indicator will light when the battery voltage reaches a point
as to allow a further 15
17
minutes of operation. It should be replaced as soon as possible.
Battery life will be 6 to 8 hours minimum and depend on the volume setting and type of program.
Make sure the volume control is set to minimum and then insert the earphone jack into the socket on the front panel.
Although the receiver has circuitry built in to suppress any clicks, we recommend you plug in the jack prior to fitting
earphones into your ears.
Make sure an audio signal is being sent to the transmitter as described on the previous page and then slowly turn up
the volume until a comfortable listening level is reached. You should expect to have the control at about the 12 o'clock
mark for normal music applications. This should give ample volume into the phones.
Prolonged listening at excessive levels may cause permanent damage to your hearing.
Programming
Transmitter
When switched on, the transmitter performs an autotest cycle (the word "TEST" will appear on the display and is set to
operate at the last frequency stored in the memory prior to being switched off (the frequency will appear on the
display).
To change the operating frequency, proceed as follows:
press the "up" (or "down") button and choose the new frequency: wait several seconds until the word "STORE"
appears and press the "function" button briefly: the message will change to "STORED"and the new frequency will
remain the operating frequency, until another change is made.
