Electro-Voice | DI-1 Digital Input Module
DI-1 Digital Input Module
▪ 128 dB dynamic range – for best audio performance
▪ 32–192 kHz sample rate – connection of any digital
audio source
▪ Sample rate converter for every input - digital audio
sources with different sample rates can be
connected simultaneously
▪ Automatic configuration – indication (message) of
installation and removal of modules via IRIS-Net
software
The DI-1 is an eight-channel digital input module for
use in an Electro-Voice N8000 system. Digital audio
signals in AES/EBU or S/ PDIF format are connected
via screw-lockable Euroblock connectors. Four
TOSLINK connectors for optical transmission of digital
audio signals are available. All inputs are equipped
with high-quality sample-rate converters. Internally the
signals are processed in 48-bit word length.
