Focusrite ISA-2

The ISA-2 uses a high-quality Lundahl LL1538 input transformer, which provides a distinct, professional character and warmth that standard interface preamps often lack. It also offers significantly more gain and headroom, making it a better choice for demanding microphones like ribbons or low-output dynamics.

Yes. The unit features front-panel instrument inputs designed to handle high-impedance signals directly, allowing you to record guitars and basses without needing an external DI box.

Variable impedance allows you to change how the preamp interacts with your microphone. By adjusting it, you can subtly alter the frequency response and character of the mic, giving you more tonal options before you even touch an EQ plugin.

Absolutely. With a gain range of 0 to 80 dB, the ISA-2 provides plenty of clean, quiet amplification for even the most power-hungry microphones, including ribbon mics.

The high-pass filter is variable, meaning you can sweep it between 16 Hz and 420 Hz. This lets you precisely remove unwanted low-end rumble or mud from your signal at the source, rather than fixing it during the mix.

Yes, the ISA-2 includes dedicated analog insert points on the rear panel. This allows you to patch in external hardware, such as a compressor or EQ, directly into your signal path after the preamp stage.
