Beyerdynamic DT 770 PRO Information De Produit page 4

Thank you for selecting the DT 770 PRO dynamic headphone.
Please take some time to read carefully through this product
information before setting up the equipment.
Design Features
The DT 770 PRO is a closed dynamic headphone and was
designed for critical music and sound monitoring in an open
environment. It has a bass-reflex system to give low-frequency
response down to 5 Hz and is equalised to the diffuse sound field.
The weight of the diaphragm and moving coil of this headphone is
approx. 20% compared to other current models. As a result, the
DT 770 PRO offers similar pulse characteristics as electrostatic
headphones. The cushion systems and light weight allow the
DT 770 PRO to be used in complete comfort for long periods.
Application
The transducers are fitted to adjustable yokes which should
be positioned to fully enclose the ear. This will provide the optimum
ear/speaker position for accurate sound monitoring. The cord is
terminated with a high-quality gold plated mini-jack and a 1/4"
stereo jack adapter. Professional users should note that it is
recommended practise that headphones are issued on an individual
user basis to preclude any possible health risks.
Maintenance
As with any equipment which will be used in close proximity
to sensitive areas of the body, it is essential that the ear-pads and
head-band are kept clean. Use a damp cloth for cleaning using
warm water only taking care not to allow any water drops into the
transducers. Should it become necessary to replace the ear-pads or
the head-band cushion, refer to "Spares and Accessories".
Safety
When plugging your headphones into an amplifier, please
make sure that the volume control is set at minimum and is adjusted
after they have been put on. It is common phenomenon to listen to
music through headphones at high levels. The very low levels of
distortion present within the DT 770 PRO can make the listening
levels higher than is preceived and we would like to warn you of
this so that you are able to enjoy these headphones for many years
without damage to your ears.
