Beyerdynamic DT 250 - Operation; Positioning Headphones and Microphone

DT 25x / DT 28x / DT 29x6
The microphone of the DT 280 / DT 290 headset is designed for
balanced connection. But it can be also connected to
unbalanced microphone inputs.
The DT 297 PV headset is suitable for the connection to balanced
microphone inputs with phantom power. At a diance of 5 cm
the microphone level is 13 mV or 250 mV.
Use the DT 280 headset with integrated preamp for connecting
to TV cameras with a microphone input for AB-powering. At a
diance of 5 cm the microphone level can be adjued between
52 mV and 1.3 V at normal speech volumes.
4. OPERATION
The head phones are fully adjuable and should be positioned
for the be fit over the ears. This will give maximum long-term
comfo and will minimise sound leakage or spill.
The microphone should be positioned to the side of the mouth,
about 20 - 30 mm forward. This will keep it within the direct sound
path but out of breath ream, therefore minimising any ‘pop’
sounds.
All versions:
The microphone boom is rotatable so
that the microphone can be placed
over the le or right ear.
