Focusrite Introduces The ‘ISA Two’ Dual-Mono Preamp
Focusrite found their spot in the limelight with the introduction of this classic transformer-based preamp back in 1985. The ISA pre was originally the heart and soul of Focusrite’s highly acclaimed Forte console and can currently be found as a single pre-amp unit (ISA One), channel strip (ISA 430 MKII), four preamp rack-mount unit (ISA 428 MKII) and an eight preamp rack-mount unit (ISA 828). Now, Focusrite fills in the gap with the introduction of the ISA Two.
The ISA Two - When one is not enough and four is too much.
No specific release date or price has been announced for Focusrite’s ISA Two but we can bet that it will be available around the $1000-or-less price range (ISA One $499, ISA 428 MKII $1,399 on Sweetwater). Check out more details of the ISA Two from Focusrite:
“Overview
You may only need a couple of mic preamps, but they need to be the very best. The ISA Two dual-mono mic pre is the ideal solution: two independent channels of the highest quality classic Focusrite mic pres, with line in and front-panel instrument inputs – no DI box required. Based on the legendary designs found in the Focusrite Forte and Studio Consoles, ISA Two is the ideal front-end for your rack.
Superb sound spanning four different decades
Focusrite’s microphone preamplifiers go back to the original Focusrite ISA 110 modules, when Rupert Neve was commissioned by George Martin in 1985 to create a no-compromise channel strip for his Neve console. Combining the very best solid-state electronics with transformer coupling, Focusrite mic pres have played a key part in the recording of hundreds of hit records and they’re the choice of leading artists, producers and engineers around the world.
Lundahl Transformers
At the heart of the ISA Two is a pair of Lundahl LL1538 transformers. ISA products have relied on Lundahl from the beginning, since their components were originally specified in 1985. The LL1538 features a 3-section winding, resulting in very low leakage inductance and, as a result, an extended frequency response. They’re encapsulated in mu-metal cans to shield them from stray magnetism.
Variable input impedance and up to 80 dB of gain
ISA Two features two classic Focusrite mic preamps, with four impedance settings including the original ISA 110 setting. Variable input impedance allows you to go for an accurate, transparent sound or choose to highlight the character of your favourite vintage mic – and anywhere in between. With up to 80 dB of low-noise gain, ISA Two can perform in the most demanding situations – really bringing your ribbon, condenser or moving coil mics to life.
Insert your choice of processors
Each channel has a fully-balanced insert point accessed via TRS sockets on the rear panel and activated with a front-panel button, so it’s easy to use outboard processors with the ISA Two. Just plug in your choice of EQ, compressor or limiter.”
