- ISA 428 MkII incorporates four of Focusrite's renowned mic pres in a simple-to-operate 2U enclosure, placing four mic preamps, instrument inputs and line ins at your fingertips. The original Focusrite mic pre was designed to suit the microphones of the time; today's model makes one small change, adding three additional input impedances to the classic ISA 110 setting, allowing you to match any microphone, old or new, and access a wide range of sounds, from the character and warmth of a vintage mic to the clear transparency of a modern design.Each mic pre has the option of mic, line or the front-panel instrument input, with variable input impedance to ensure you are getting the best performance from the source. Up to 60dB of gain is available on the four-position rotary and gain range switches, with a further +20dB of continuously variable trim, meaning a huge 80dB of gain is available should it be required. The high-pass filter features variable cut-off frequency between 16 and 420Hz. An array of 6-segment LED meters show peak signal level for the four mic pres, in addition to the four direct inputs to the optional A-D card. Switchable rear-panel insert points allow the use of inline processors such as compression.
- The ISA 828MkII incorporates eight of Focusrite's classic mic preamps, with Lundahl LL1538 transformers on every input. Each channel has the option of mic or line inputs,while inputs 1-4 also feature instrument inputs on the front panel. Each mic pre has variable input impedance, to provide a range of subtly different sonic options when using microphones, including an 'ISA 110' setting, which replicates the impedance of the original Focusrite mic pre.Up to 60dB of gain is available, with a further +20dB of continuously variable trim,providing a huge 80dB gain range. The high-pass filter has a fixed 75Hz frequency and 18dB / octave roll-off for minimising rumble, stand-borne noise and other low-frequency sounds. The ISA 828 MkII also features per-channel,six-segment LED meters, and switchable rear-panel insert points, which allow the use of inline processors such as compressors or EQs.Dedicated connectors for mic and line-level inputs allow all sources to be connected simultaneously, making ISA 828 MkII perfect for permanent installation in a rack. A switching power supply allows for efficient, cool operation, without sacrificing sound quality or performance, and increasing reliability over its predecessor. The optional ISA ADN8 analogue-to-digital expansion card provides eight Dante, ADAT and AES3 outputs at sampling rates of up to 24-bit / 192kHz.And as with all Focusrite Pro products, wherever you happen to be in the world, you can rely on a three-year warranty if any Focusrite Pro hardware needs repairing or replacing due to a manufacturing fault.
- ISA ADN2 is an optional two-channel A-D card that provides high-quality analogue-to-digital conversion for the ISA One mic preamp and DI. Featuring Dante, AES3, ADAT andS/PDIF connectivity, the card operates at sample rates up to 24-bit/192kHz.The card offers primary and secondary RJ45 Dante output ports, an XLR connector for AES3 output, a TOSLINK connector for ADAT output and RCA connector for S/PDIFoutput. Word Clock I/O on BNC connectors allows synchronisation to multiple digital sources. This also includes syncing the Dante network to house clock,or for syncing external equipment to the Dante network.Dante outputs on the card provide ISA One with network connectivity to all Focusrite RedNet devices and Red interfaces, as well as any other Dante-enabled device from hundreds of manufacturers. Metering and settings are accessed through RedNet Control, routing is configured using Dante Controller.And as with all Focusrite Pro products, wherever you happen to be in the world, you can rely on a three-year warranty if any Focusrite Pro hardware needs repairing or replacing due to a manufacturing fault.

- Featuring a rugged, portable all-metal enclosure, ISA One combines the classic Focusrite microphone preamp with a flexible, independent DI channel and optional 192kHz precision A-D conversion. At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA 110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can't be truly emulated in any other way, while the modern twist of variable input impedance allows for a new degree of flexibility.Whether you're an artist, engineer or producer, you'll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A-D converter and separate rear-panel XLR output.
- Focusrite's ISA Two brings together a totally independent pair of classic ISA microphone preamps from the original ISA 110 module, combining the best of traditional solid-state electronics with the original input transformer specified by Rupert Neve – the Lundahl LL1538.Each mic pre has the option of mic, line or the front-panel instrument input, with variable input impedance to ensure you are getting the best performance from the source. Up to 60dB of gain is available on the first four-position rotary and gain range switches, with a further +20dB of continuously variable trim, meaning a huge 80dB of gain is available should it be required. The high-pass filter features variable cut-off frequency between 16 and 420Hz. A pair of 8-segment LED meters show peak signal level in dBFS, while a rear-panel pot allows calibration to suit your A-D converters. Rear-panel insert points allow the use of inline processors such as compression.
- The V 402 is a state-of-the art dual channel microphone preamplifier with an integrated studio grade headphone amplifier. Its transformerless circuitry is designed for maximum transparency and sonic purity. The V 402 is thus the perfect complement to all Neumann microphones in order to unveil the true character of voices and instruments.The V 402 is Neumann's first-ever stand-alone microphone preamp, although the company has created several generations of top-quality preamp modules for its mixing consoles, such as the now legendary V 476 B of the 1980s. Technology, of course, has moved on. Yet the fundamental question remains: What would be the perfect preamp for Neumann and other high-quality studio microphones? All Neumann microphones, classics as well as current models, have highly unique sound characteristics. The V 402 preamplifier is thus designed to preserve the integrity of the microphone's sound image. At any gain setting, it neither adds or detracts. Perfection cannot be perfected!Two-channel transformerless microphone preamp with switchable 20 dB pad. Includes (3) mains cables (US, EU, UK) and (1) set of rubber feet
