Sennheiser HME 25-1

General Description The HME 25-1 headset features dynamic, closed headphones and a broadcast quality MKE 2 Red Dot omni-directional close-talk microphone. It has been designed specifically for use in noisy environments. Background noise attenuation is achieved by the extreme closeness of the microphone to the mouth. In addition, omni-directional microphones do not suffer from increased low frequencies (proximity effect) and so give a natural sound at close talking distances. Features Broadcast quality microphone with superb transmission qualities due to extremely flat frequency response Very light Two-piece padded headband, exceptionally comfortable Microphone can be worn on either left or right-hand side Delivery Includes 1 HME 25-1 1 windshield MZW 1410 Technical Data Transducer principle (Headphones) dynamic Ear coupling supra-aural, closed Frequency response 30...16.000 Hz (Headphones) Characteristic SPL (1 kHz, 1 mW) 102 dB +- 3 dB Nominal impedance 600 Ohm per side Load rating 200 mW THD, total harmonic distortion <0,5 % Contact pressure approx. 3,3 N Weight w/o cable approx. 190 g Transducer principle (Microphone) back-electret condenser microphone capsule Frequency response 40...20.000 Hz (Microphone) Pick-up pattern omni-directional Sensitivity in free field, no load (1kHz) 6,7 mV/Pa Impedance min. 4,7 kOhm (Terminating) Power supply 5 - 15 VDC Connection cable 1,8 m stell cable, open ends
