DIGI-SYS HP Distributor-3D is a 1U rack-mount unit, which accepts AES/EBU, SPDIF & Analogue
inputs in the form of Balanced and Unbalanced with its inputs selection switches. It produced analog
output through professional TRS jack which can drive all types of stereo headphone with its volume
control.DIGI-SYS HP Distributor-3D accepts balanced AES/EBU signal and SPDIF unbalanced signal in
addition to stereo balanced input, with Sample Rate Frequency range from 16 KHz to 192 KHz. This unit
has Superior performance with excellent signal to noise ratio and low distortion. Stereo analogue inputs
have fine ±20dB pre-set analog level controls additional with ±20dB digital gain control. The large
dynamic range is optimized by microcontroller with full scale resolution as per user requirements.
DIGI-SYS HP Distributor-3D has excellent overall frequency response and very low distortion, which
has been achieved by selectively mixing integrated circuits and discrete devices. Extremely low internal
noise levels achieved, also allow perfect recovery from week digital signals in the range of 100 mV.
The unit is housed in a 19” rack mount chassis with power connections as per IEC recommendation.
