Which cable should I use for the DT 109?

The DT 109 is delivered without a cable. Recommended accessories: K 109.00 (free ends, 1.5 m), K 109.28 (XLR 4-pin, 1.5 m), K 109.38 (XLR 5-pin, 1.5 m).

What is the impedance of the DT 109 headphone?

The nominal headphone impedance is 400 Ω per system. Versions with 200/50 Ω and 200/400 Ω are available.

Is the DT 109 compatible with an intercom system?

Yes, it is designed for concert intercom systems and radio/TV broadcast. Use the appropriate cable (XLR 4 or 5-pin).

How can I avoid pop effects with the microphone?

Position the microphone about 2–3 cm from the corner of your mouth. Use the supplied pop filter.

What should I do if the sound is defective?

Check the connections and cable condition. The internal earpad cables are soldered (recent versions) or screwed (older versions). Contact an authorized Beyerdynamic technician.

Where can I find spare parts for the DT 109?

Thank you for selecting the DT 100 dynamic studio headphone or the DT 108/109 dynamic headset. Please take some time to read carefully through this operating instructions before setting up the equipment.

Design Features

DT 100

The DT 100 are fully enclosed dynamic studio headphones with excellent ambient noise attenuation. They are ideal for use in broadcasting, film and recording studios.

The DT 100 is a double-sided headphone.

The headband and earphone cushioning has been carefully designed for maximum comfort during long periods of listening.

The connecting cables to the ear monitors run safely in the headband and the main connecting cable is terminated on one side with a multi-pin connector.

DT 108 / DT 109

The DT 108/109 are the same as the DT 100 headphones, with the addition of a dynamic hypercardioid microphone. The DT 108/109 headset is used for intercom and talkback systems as well as other applications where a dynamic microphone headset is required.

The DT 109 is a double-sided headset while the DT 108 is the single-side version.

Connection

The DT 100 studio headphones are supplied with connecting cable; the DT 108/109 headsets are supplied without connecting cable. For appropriate connecting cables, please refer to "Optional Accessories".

The K 100.00 connecting cable is built using a tinsel-conductor cord. This type of conductor resists repetitive bending without breaking, yet special care must be taken when making solder joints to connectors. Wherever possible it is recommended 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 tinselconductors 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 bare-ended cables (for cable connections, please refer to "Wiring Diagram"). On request, the necessary plugs can be fitted when the order is placed.

Operation

The DT 100 studio headphone and the DT 108/109 headset are professional products. It is important that the external equipment they are connected to is of similar quality and has the correct impedance and power ratings to achieve the best performance. Please refer to the “Technical Specifications” for detailed information.

Convention states that when using the DT 108/109 the boom microphone is placed over the left ear. The microphone can be used from the right ear, but if true L and R headphone status needs to be maintained, it will be necessary to make a custom lead with the headphone connections reversed (swap brown/orange on the left side and red/blue on the right side). For connections refer please to "Block Diagram".

2 Loosen flat screw.
3 Turn disc 180°. Nose of the disc points to the upper end. of the boom arm.

4 Tighten flat screw and put cap on turning knob.

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 the breath stream, therefore minimising any 'pop' sounds.

Important!

Please note that there have been two versions of ear cup connecting cables used during production. The older DT 100 models have a cable with screw terminal contacts whereas later versions have soldered connections. Please make sure the correct cable version is requested when ordering.

Maintenance

To keep the headband and earpads clean use a damp cloth with a gentle cleansing agent (such as washing-up liquid). Make sure not to allow any water to enter the transducer elements. Do not use any solvent cleaners.

The microphone pop-shield of the DT 108/109 headset can be easily removed and washed in warm water. Please take care that the pop shield is completely dry before it is replaced.

The fully modular design of the DT 100 and the DT 108/109 allows field replacement servicing without the need for specialist tools. The order numbers of the spare parts are listed under "Spares".

In the unlikely event of equipment failure, the product should be returned to your beyerdynamic dealer.

Safety

We strongly recommend that the headphone or headset is plugged into the drive amplifier before you put them on. This will give the technician the chance to check that the volume levels are not too high.

Be aware that the very low levels of distortion can make listening levels higher than is perceived. Please take into consideration, that too high level hearing may lead, after considerable time, to irrevocable hearing damage.
