HEAD DD ata Sheet atenblatt Ebertstraße 30a 52134 Herzogenrath Tel.: +49 2407 577-0 Fax: +49 2407 577-99 eMail: firstname.lastname@example.org Web: www.head-acoustics.de HD IV.2 (Code 2481) Open, dynamic headphone Overview The HD IV.2 is a top class, open, dynamic headphone using customdeveloped materials for optimal sound characteristics. Its computeroptimized magnet system geometry minimizes distortions and intermodulations, and its neodymium iron magnets provide for the maximum possible efficiency. For aurally accurate playback, the headphone equalizer labP2 is programmed with the individual equalization and level calibration parameters of the HD IV.2, thus ensuring that users achieve a natural reproduction of their recordings. Features Accessories (not included) ·· Open, dynamic headphone ·· labP2 (Code 3732) Binaural headphone equalizer with USB interface, HEADlab-compatible ·· labO2 (Code 3731) 2-channel playback equalizer with Line outputs, USB interface, HEADlab compatible ·· HDA IV.1 (Code 2488) HEADphone Distribution Amplifier for 4 x HD IV.2 ·· HDA IV.2 (Code 2489) HEADphone Distribution Amplifier for 8 x HD IV.2 ·· Natural, spatial sound characteristics with high timbre fidelity ·· High degree of efficiency ·· High wearing comfort ·· Balanced, defined bass and real lowbass playback ·· Extremely lightweight aluminum coils for maximum pulse fidelity Scope of Supply ·· HD IV.2 (Code 2481) Open, dynamic headphone ·· Adapter (6.3 mm stereo jack) Technical Data Frequency response: 16 to 30000 Hz (-3 dB) 10 to 39500 Hz (-10 dB) Transducer type: dynamic, open Nominal impedance: 300 Ohm Nominal sound pressure level at 1 kHz: 103 dB (1 Vrms) Nominal power handling: 500 mW according to EN 60-268-7 Distortion according to DIN 45500: ≤ 0.05 % Ear coupling:circumaural Pressure force: approx 3.4 N ± 0.3 N Weight (without cable): 260 g (0.57 lb) Connection cable: copper cable, 3 m (9.8 ft) 12.2014 D2481e2 Subject to change A HDA IV HEADphone Distribution Amplifier connected to the playback equalizer labO2 allows a high-quality playback via four (with HDA IV.1) or even eight (with HDA IV.2) levelcalibrated HD IV.2 headphones simultaneously. Furthermore, the HD IV.2 can also be connected to the built-in headphone output of the digital artificial head measurement systems of the HMS IV generation and to the mobile recording and playback system SQuadriga II.
