ADIT0x0 Digital Audio Isolator

The ADIT0 range of AES3 and MADI Isolators are critical components for implementing ground isolation, protection and noise reduction in AES3 and MADI I digital audio signals.

The ADIT AES3 and MADI Isolator is available in two voltage ranges, 1kV and 4kV. It is also available in two compact packages; a standalone unit and rack mounting unit. The rack mounting version has a standard XLR mounting profile allowing it to be mounted on to a XLR rack mounting plate.

These units are available online, or you can contact us or your local distributor.

Description

Digital Audio Isolator

The ADIT Digital Audio isolator are critical components for implementing ground isolation, protection and noise reduction. The digital audio isolator is usable as a AES3 Isolator and MADI isolator.

  • Protect Equipment from ground voltages
  • Standard isolation better than 1kV and extended isolation up to 4kV
  • Supports all AES3 formats
  • Compatible with MADI digital audio signals
  • Passive device
  • High performance and wide bandwidth design
  • Ultra-compact and lightweight
  • Standalone unit and rack mountable versions

 

Description:

The ADIT0x0 range of Digital Audio Isolation transformers is a transformer based solution providing the reduction and elimination of hum and noise caused by differences in ground potential, especially those above 20 volts, or induced currents in long cable runs. As a result, these ground problems manifest themselves as signal noise on the digital audio transmission.

Hence, the resultant common mode noise causes degradation of the bit timing of the high speed digital signal leading to bit errors. a consequence of the bit errors is a  reduction of the quality of the audio and data content within the transmission signal. Digital signals do not degrade gracefully as they often suffer from a cliff-effect causing the signal to be lost altogether.

However, the singular most common symptoms of hum in digital audio is intermittent clicks in the audio.

Installing an isolation transformer is crucial in implementing ground protection. This occurs when ground or earth potential differences are in existence between equipment. As a result, permanent damage to video equipment is often the consequence. Damage of this nature is not only costly but, crucially, could also take an audio signal off-air.

The isolator is usable as an as AES3 Isolator and MADI isolator.

Both 1kV and 4kV isolation voltages are available and the 4kV unit is ideal for non-broadcast applications such as industrial, medical, oil and gas.

The ADIT0xo range of Isolators is available in three compact packages, a BNC standalone unit a BNC rack mounting unit and an XLR unit which can be standalone or rack mounted.. The rack mounting versions have a standard XLR mounting profile allowing it to be mounted on to a XLR rack mounting plate.
