Focusrite Introduces New ISA 220 Session PackBased on topology of ISA 430 Producer Pack
ISA 220 is a single-channel analog processor housed in a 2U, 19 rackmount enclosure, designed to provide audio professionals in music and post with a complete channel strip of legendary Focusrite processing at a competitive price point. Based on the topology of the TEC award nominated ISA 430 Producer Pack, ISA 220 shares a number of similar processing functions with its big brother.
ISA 220 starts with the classic Focusrite transformer-coupled microphone preamp plus line and instrument inputs with phantom power and phase reverse. The next section consists of a four-band EQ plus high-pass and low-pass filters based on the EQ circuits from the ISA 430. The compressor features a proprietary Class A VCA and side-chain circuitry and can be easily placed before the EQ in signal flow. The compressor also includes a unique new ?Blend feature ? providing a means of achieving smoother compression at extreme settings by mixing some of the uncompressed signal along with the compressed portion. Following the compressor is an opto-based de-esser, which uses a combination of EQ and phase cancellation for a smoother, less obtrusive de-esser than conventional designs. Last but not least, a frequency adaptive, 3-band limiter is provided to ensure distortion-free limiting. Each ISA 220 processing section includes individual bypass switches as well as a master bypass for the entire signal path.
For visual reference, ISA 220 provides a classic analog VU meter and can be switched to display input or compressor gain-reduction levels. A pair of 16 segment LED meters is included to display output levels in conjunction with the optional A/D output card. A complement of XLR and 1/4 TRS jacks is provided on the rear panel for microphone input, line input/output, key input to the compressor, etc. A 1/4 TRS instrument input jack is also provided on the front of the unit.
An optional 24-bit/96 kHz digital output (AES/EBU,S/PDIF &TOSLINK) offers 44.1 96 kHz operation,16-, 20-and 24-bit resolution selection, and can lock to external Word Clock, including Pro Tools Super Clock. It can be used as a high-quality mono/stereo tracking converter, or at mixdown as a stereo converter for final mastering.
ISA 220 is currently shipping and carries an MSRP of $2,295 (USD). The optional 24-bit/96 kHz A/D board will follow and will have an MSRP of $525 (USD).
