NOTICE D'UTILISATION DT 150 - DT 190

Thank you for selecting the DT 150 professional studio microphone 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 hypercardioid 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 renowned 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.

Operation

The DT 150 and DT 190 are of a professional standard. It is important that the external equipment they will be connected to are of good quality and of the correct impedance and power ratings to get the best performance from them. Please refer to the "Technical Specifications" for detailed information.

The headphone is fully adjustable and should be positioned for the best fit over the ears. This will give maximum long-term comfort and will minimise sound leakage or spill.

Convention states that with the DT 190 the boom is placed over the left ear and the earphones of the DT 190 are identified: L and R (left and right). The microphone can be used from the right ear, but if true L and R status should be maintained, or split feeds are in operation, it may be necessary to make a custom lead with the headphone connections reversed. The L&R nomenclature plates of the DT 190 can also be swapped to reflect these changes.

DT 190

1. Lift cap with small screwdriver.

1. Turn disc 180^ . Nose of the disc points to the upper end of the boom arm.

2. Tighten flat screw and put cap on turning knob.

The microphone should be positioned to the side of the mouth, about 20 - 30mm forward. This will keep it within the direct sound path but out of the breath stream, therefore minimising any 'pop' sounds. Of course every user will be different and a degree of experimentation will be necessary to achieve the preferred result. Professional users should note that it is recommended practise that headsets 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 parts of the body, it is essential that the ear pads, the headband and the microphone pop-shield are kept clean. Use a damp cloth for cleaning the ear-pads and headband using only gentle cleansing agents (such as washing-up liquid). Take care not to allow any water drops into the transducer elements and do not use any solvent cleaners.

The microphone pop-shield of the headset can be easily removed and washed in warm water. Please take care that the pop-shield is completely dry when it is replaced.

The fully modular design of the DT 150 and DT 190 allows for full, in-field serviceability without the need for specialists tools. Every item of the assembly is available as a spare part and no special training is necessary for servicing. The Order Numbers of all of the spare parts are listed under "Spares", "Supplied Accessories" and "Optional Accessories". Please take care to identify the parts required by the Order Number as there are many options, especially for the transducer parts and the cable assemblies.

Safety

When plugging in headphones or headsets to the drive amplifier, we recommend that this is done before it is fitted over the ears for use. This will give the technician the chance to check that the volume levels are not too high. Please remember that the user could well be a highly-paid presenter and the consequences of damaging his/her ears may well prove to be music to the ears of the lawyers!

The very low levels of distortion can make listening levels higher than is perceived and we have to warn you that listening to programme or talkback at high levels for long periods can permanently damage your hearing.
