NEC DT 190, DT 150 manual Operation

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.
