EuroSynth Specification

Signal Specifications - AUDIO

Audio signals are bi-polar AC voltage signals that range in frequency from around 16Hz to greater than 16kHz and are specified in decibels (dB).

The voltage levels for Audio signals is based on the professional recording studio figure of

+4dBu (sine wave = 3.5VAC pk-pk).

This level provides for at least 16dB of headroom which is essential for the dynamics of music when mixing and gating signals.

For compatibility with the other signal types, EuroSynth raises this figure to 5VAC pk-pk.

AUDIO IN

  • AUDIO IN signals are typically 5VAC pk-pk but can extend to 10VACpk-pk
  • AUDIO IN signals are typically in the range 16Hz to > 16kHz

AUDIO OUT

  • AUDIO OUT signals are set at 5VAC pk-pk +/-10%
  • AUDIO OUT signals are typically in the range 16Hz to >16kHz
