Focusrite ISA Two

Variable input impedance allows you to change how the preamp interacts with your microphone. By adjusting this setting, you can alter the frequency response and character of your mic, letting you fine-tune the sound to be brighter, darker, or more open depending on the source.

Yes, the unit features front-panel instrument DI inputs specifically designed for guitars and basses. These inputs have a high impedance of 2 MOhm, which ensures your instrument's signal remains clear and retains its full frequency range before hitting the preamp.

Absolutely. With 80dB of clean gain, the ISA Two provides plenty of headroom for low-output microphones, including ribbon mics and dynamic mics like the Shure SM7B, without introducing unwanted noise.

The variable high-pass filter, which ranges from 16 Hz to 420 Hz, allows you to surgically remove unwanted low-end rumble or mud from your signal at the source. This helps keep your tracks clean and prevents low-frequency buildup before the signal even reaches your interface.

The Lundahl LL1538 input transformer is a classic component that provides the signature 'ISA' sound. It adds a subtle, musical coloration and harmonic richness to the signal that is often missing from standard, transformerless interface preamps.

Yes, the LED metering is user-calibrated, allowing you to align the preamp's output levels with your specific digital audio interface. This ensures that what you see on the hardware meters accurately reflects the signal level hitting your DAW, helping you avoid digital clipping.
