Focusrite ISA 220 Session Pack
The ISA 220 starts with the classic Focusrite transformer-coupled microphone pre amp, with phantom power and phase reverse. A four-band Focusrite EQ section follows, based on the EQ circuits featured in the ISA 430 and ISA 110. The compressor features a proprietary Class A VCA with side-chain circuitry, and can be placed in the signal flow before the EQ at the press of a button, if desired. Also included is a unique feature labelled “Blend”, which provides a means of achieving smoother compression at extreme settings by mixing uncompressed source signal along with the compressed portion.
The ISA220 also features an opto-based de-esser which uses a combination of EQ and phase cancellation to create a smoother and less obtrusive result. Last but not least, a frequency adaptive, 3-band limiter is provided to ensure distortion-free limiting. For visual reference, ISA 220 provides a classic analogue VU style meter which can be switched to display input or compressor gain-reduction levels. A pair of 16 segment LED meters are included to display output levels, both analogue and digital in conjunction with the optional 24-bit/96 kHz stereo digital output (AES/EBU, S/PDIF & TOSLINK) card. This card offers 44.1 - 96 kHz operation and can be used as a high-quality mono / stereo tracking converter, or at mix down as a stereo converter for final mastering.
