Product Description

The Quantum ES 2 is a 2 x 2 USB-C recording interface with 24-bit audio and sample rates up to 192 kHz, built for home studios, podcasts, songwriting, and mobile recording. Two combo microphone inputs provide up to +75 dB of gain, +48 V phantom power, and a low-noise path for detailed takes. Auto Gain sets microphone and guitar levels with one button, while the custom low-latency driver keeps monitoring responsive during overdubs. Line connections, balanced main outputs, a headphone jack, and 3.5 mm Type-B MIDI I/O cover common desktop setups. Top-panel controls and a control app handle gain, phantom power, and other preamp settings without interrupting your session. The package includes a 1.5 m USB-C to USB-C cable and six months of recording software membership.

Features

Detailed Vocal Capture

Two microphone preamps provide up to +75 dB of gain, with 113 dB dynamic range and low noise for detailed vocal and mic recordings.
Responsive Monitoring

A custom low-latency driver reduces signal lag while recording, so vocals, guitars, and other sources stay responsive during overdubs and live takes.
Faster Level Setup

Auto Gain sets microphone and guitar levels with one button, helping you start takes quickly without repeated manual adjustments at the interface.
High-Resolution Sound

24-bit digital audio supports sample rates from 44.1 through 192 kHz, preserving the detail needed for music, podcasts, and voice work.
Control Where You Work

Top-panel controls and a mobile or desktop app handle gain and phantom power, keeping critical settings accessible during focused recording sessions.
