Focusrite ISA Two Classic Dual Mono Transformer-Based Microphone Preamplifier
Twin channels of exquisite pre-amplification, with front-panel DI for easy instrument connection.
The ISA Two is the ideal front-end solution for any studio rack, with two independent channels of Focusriteâs high-quality microphone preamps, each with their own front-panel instrument inputs, so no additional DI boxes are required. Based on the legendary designs found in the Focusrite Forte and Studio Consoles, ISA Two will easily integrate into any audio signal path.
Superb sound spanning four different decades Focusriteâs 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 theyâre 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. Theyâre 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 favorite vintage mic â 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 itâs easy to use outboard processors with the ISA Two. Just plug in your choice of EQ, compressor or limiter.
