ISA Range
No-compromise mic pres descended from legendary consoles
Focusrite created the ISA 110 for Sir George Martin’s Neve console at Air Studios in 1985. And ever since, the Focusrite name has been associated with no-compromise mic pres. The legacy of the original ISA 110 endures today within the Focusrite ISA range and in every mic pre the company designs.
The term “ISA” is an acronym for “Input Signal Amplifier.” Today’s range of Focusrite ISA products is directly descended from the original Focusrite Forte consoles of the late ’80s and the Studio Console the company developed in subsequent years. The core modules of those iconic consoles live on in the current range of now-classic ISA products. Each ISA offering includes a Lundahl LL1538 input transformer and a custom Zobel network, which only reinforces their sought-after sound.
| Number of Mic Pres | Number of Instrument Inputs | Input Impedance Switching | Variable Highpass Filter per Channel | Available Gain per Channel | Insert Send/Receive per Channel | Optional Dante Card | Cue Mix | |
| ISA One | 1 | 1 | Yes | No | 60dB | Yes | Yes | Yes |
| ISA Two | 2 | 2 | Yes | Yes | 60dB | Yes | No | No |
| ISA 428 MkII | 4 | 4 | Yes | Yes | 60dB | Yes | Yes | No |
| ISA 828 MkII | 8 | 4 | Yes | No | 60dB | Yes | Yes | No |
ISA One
Legendary console sound in a portable, 1-channel format
Take the legendary sound of a Forte console anywhere with the Focusrite ISA One desktop microphone preamp. This 1-channel mic pre is based on the original ISA 110 circuit and instantly imparts iconic sonic character into any signal. While the sound is nearly identical to the originals, this unit boasts a feature that the originals don’t: four selectable input impedances. This allows you to match a microphone to the input in whatever way you want. You can go clean and transparent or really bring out the character of a classic mic in your locker. There’s also a flexible and independent DI channel that’s active whenever the pre is active. The mighty ISA One’s mic- and instrument-level inputs run in parallel, so you can blend them to taste. Finally, it has a fully featured digital output section with main, DI, cue mix, and headphone outputs.
Features:
- 1-channel transformer-based preamplifier
- Compact and portable metal chassis
- Four switchable input impedance values
- Parallel mic- and instrument-level inputs
- Lundahl LL1538 input transformer
ISA Two
2 channels of iconic Focusrite console sound
The Focusrite ISA Two 2-channel microphone preamp takes the sonic architecture of the ISA One and reimagines it in an easy-to-use 1U rackmount unit. You get two channels of preamplification for mic-, line-, and instrument-level sources. This unit has a massive 80dB of gain on tap, which is more than enough to drive the lowest output ribbon microphones in any mic locker. Like the ISA One, the ISA Two includes variable input impedance, which enables you to tailor the preamp to better fit your microphone — even if that means breaking the rules to achieve the sound in your head. There’s also user-calibrated LED metering onboard.
Features:
- 2-channel transformer-based preamplifier
- Provides up to 80dB of gain
- Variable input impedance
- User-calibrated LED metering
- Lundahl LL1538 input transformer
ISA 428 MkII
4-channel rackmount preamp inspired by the Forte series
Simple operation and a space-saving 2U chassis make the 4-channel Focusrite ISA 428 MkII microphone preamp a no-brainer for studio use. Like all ISA preamps, this 4-channel mic pre is based on the classic Forte and Studio consoles. It delivers a massive 80dB of gain and comes with variable highpass filters on each channel to cut out rumble and unnecessary low-frequency information. Every channel delivers a warm and transparent sound, thanks to the variable input impedance. The streamlined control layout provides an uncluttered user experience without sacrificing performance. And on the back, you’ll find four A/D converter inputs with a 122dB dynamic range and low-jitter performance.
Features:
- 4 channels of classic transformer-based preamps
- Switchable input impedance
- Line-, mic-, and instrument-level inputs
- Ultra-accurate LED metering

This rackmount preamplifier has eight preamps with Lundahl LL1538 transformers on every input. You get mic and line inputs for each channel, plus four switchable input impedances for microphone matching. The ISA 828 MkII provides up to 80dB of gain, a fixed 75Hz highpass filter, and 6-segment LED meters. Finally, the ISA 828 MkII has dedicated connectors for mic- and line-level inputs, so all sources can be connected simultaneously. And did we mention that the ISA 828 MkII has a rear-mounted DB-25 connector for A/D inputs? And when paired with the optional Focusrite ISA ADN8 8-channel A/D card, this gives you high-precision digital audio conversion and switchable insert points.

Sample Configurations
Pro Tools | HD Recording Studio Setup
For a 2-room Pro Tools | HD studio setup, RedNet allows seamless integration with the Dante network. Control room monitoring and line inputs are provided via a Red 16Line fitted with a Pro Tools | HDX card, fed by an ISA 430 MkII channel strip front end. In the live room, two RedNet MP8R units provide 16 channels of remote control mic pres, while two RedNet AM2 units provide artist monitoring. A network switcher is used for routing flexibility.
Simple Studio Setup
In this configuration, which uses a single network switch as its hub, the control room plays host to a Red 4Pre, connected to a computer via Thunderbolt and feeding powered monitors. In the live room, a RedNet MP8R provides eight preamps, while a RedNet X2P supplies headphone monitoring. Another X2P handles mic preamplification and artist headphone monitoring for the vocal booth.
House of Worship & Live Applications
RedNet is also scalable for use in larger facilities. For front of house, four RedNet MP8R units feed the console with 32 mic preamps. A RedNet AM2 provides headphone monitoring at the mix position, while a RedNet D16R feeds the PA speaker arrays. A RedNet A16R feeds powered speakers in a spillover room. Each switch in the system provides breakout/in on Ethernet ports to which all connections are made via Cat 6 cabling. For the recording studio, a feed is sent to a second switch, which is connected to a computer and a Red 16Line, which in turn feeds the studio monitors.
Multiroom Educational Facility
This facility has three control rooms, a machine room, a live room and vocal booth, and a concert hall at a separate location. The three control rooms each employ a computer and a Red 16Line fitted with a Pro Tools | HDX card, all feeding the network switcher in the machine room. In the live room, also connected to the machine room switcher, is a RedNet MP8R (with eight preamps) and one or more RedNet AM2 units for artist headphone monitoring. The vocal booth is outfitted with a RedNet X2P, which handles mic preamplification and artist headphone monitoring. At the concert hall, another network switch receives feeds from four RedNet MP8R units (for a total of 32 preamps) and a RedNet AM2 for local headphone monitoring. The remote switcher sends an output feed to the main machine room switcher.
