Focusrite ISA 2 Microphone Preamp

The ISA 2 is built on the legendary transformer-based design found in classic studio consoles. Unlike the preamps built into most audio interfaces, this unit offers a distinct, high-quality sonic character, significantly more headroom with 80 dB of gain, and variable impedance settings to perfectly match the specific microphone you are using.

Yes. The front panel features dedicated instrument inputs with high impedance, allowing you to plug your guitar or bass directly into the unit for a clean, professional signal path before it hits your interface.

Variable impedance allows you to change how the preamp interacts with your microphone. By adjusting the impedance, you can subtly alter the frequency response and tone of your mic, letting you brighten up a dark ribbon mic or smooth out a harsh condenser without needing EQ.

Absolutely. With up to 80 dB of gain available, the ISA 2 provides more than enough clean, quiet amplification to drive even the most demanding low-output ribbon or dynamic microphones without introducing unwanted noise.

Yes, the ISA 2 includes fully balanced insert points on the rear panel. This allows you to easily patch in your favorite outboard compressors, equalizers, or other processors directly into the signal chain after the preamp stage.

Yes, the +48V phantom power is individually switchable for each of the two channels. This gives you the flexibility to use a condenser microphone on one channel and a ribbon or dynamic mic on the other without risk.
