OPERATING INSTRUCTIONS DT 150 - DT 190
Thank you for selecting the DT 150 professional studio head-
phone or the DT 190 professional headset. They have been made
in Germany from high-grade materials and assembled under
stringent quality and performance tests to provide you with a
professional communications tool. Please take some time to read
through this instruction sheet to give you an idea of the design
criterion and some information on connection, use and
maintenance.
Design Features
DT 150
The DT 150 is a closed dynamic studio headphone and it is
configured for use in broadcasting, film and recording studios.
The headphone is fully modular for easy servicing. A multi-
conductor cable is used to connect the DT 150 to external sources
and destinations via a custom connector assembly. Spare cables
for the DT 150 are available as straight or coiled. The headband
and earphone cushioning systems have been carefully designed
for maximum comfort and serviceability as we appreciate that the
DT 150 will be used for long periods of time.
DT 190
Same as the DT 150, but featuring the dynamic hyper-
cardioid microphone DM 190 on a fully adjustable boom arm. It
is configured for use with commentators at sports events and
other situations which require precise audio performance from an
integrated headset. It is one of the DT 100 family of headphone
products which are renown throughout the world as the definitive
standard for monitoring and communications.
Connection
The studio headphone DT 150 and the headset DT 190 are
delivered without connecting cable. For the connecting cables
available refer to “Optional Accessories” (page 13).
The connecting cable K 100.00 is constructed using a tinsel-
conductor cord. This type of conductor resists repetitive bending
without breaking, but special care must be taken when making
solder joints to connectors. Where possible it is recommended to
fit crimped brass sleeves to the conductors and then solder the
sleeve to the connector. If direct solder connections have to be
made, use a high-temperature solder-pot to tin the tinsel
conductors before making the solder joint to the connector, but
be careful that the nylon thread does not melt. Direct solder
connections can be made to all other cables with free ends (for
cable connection refer to “Wiring Diagram” pages 14-15). On
request, the necessary plugs can be mounted at the factory.
