Focusrite ISA 220

The ISA 220 Session Pack provides all you need to record your session with precision and Focusrite sonic performance. It features many of the original circuits of the flagship ISA 430 Producer Pack along with some new features of its own. It also features the same digital option as the ISA 430, providing you with a high quality digital route direct from the 220 into your digital recording system.

• Precision VU metering of input level or compressor gain reduction (switched)
• 16 LED Digital Output meters for both internal and external inputs
• Classic Focusrite transformer based Mic pre
• Switched High and Low pass filter controls
• Switched High and Low shelving filter frequency controls
• Optional Stereo A/D – 24 bit 96 KHz Delta Sigma converter running at 128kHz oversampling: dithers down to 20- or 16-bit
• Proprietory Focusrite discrete Class A VCA Compressor side chain design for lower distortion and Noise performance
• Illuminated push button for switching the compressor between pre and post EQ
• New Blend feature for adding dynamics into the compressed signal path
• New De-esser design based on optical technology for lower distortion and transparency
• 'De-esser Listen' for precise control over sibilance
• Frequency adaptive limiter to avoid critical digital overs

  • Connector: XLR
  • Signal: Balanced
  • Operating Level: +4dBu
  • Maximum O/P Level: +26dBu
• Ext A/D IP
  • Connector: XLR/Jack
  • Signal: Balanced

  • Inserting a jack breaks the connection of the A/D input from the inernal signal path (fed by whatever is connected
    to the mic, line or instrument inputs) and routes the signal from the jack directly to the left channel of the A/D converter (via the meter and limiter).
