HDA IV is a high-quality distribution amplifier (HDA stands for "Headphone Distribution Amplifier") to which multiple headphones can be connected for binaural playback. Using HDA IV with labO2-V1 playback equalizer ensures acoustically accurate playback. With HDA IV distribution amplifier, custom level calibration for each individual headphone is a standard feature. HDA IV is particularly suited to jury testing with SQala software.
Two versions of the distribution amplifier are available:
- HDA IV.1: Up to 4 dynamic headphones can be connected
- HDA IV.2: Up to 8 dynamic headphones can be connected
The distribution amplifier is cascadable. This means that even more than four/eight headphones can be used simultaneously.
