TOPPING E2x2 Audio Interface Core Selling Points This 2-in/2-out professional audio interface targets creators with premium audio performance and flexible functions. It adopts self-developed ultra-linear mic preamps with EIN as low as -130.5dBu, retaining full recording details with minimal background noise. Built-in 48V phantom power switch works seamlessly with condenser and dynamic microphones. The exclusive LNRD low-noise reference voltage module stabilizes AD/DA chips, delivering 115dB DNR for both ADC and DAC for pure, transparent sound transmission. Equipped with NFCA-LE headphone amp, it only has a 0.9uVrms noise floor and 1-ohm output impedance. It outputs up to 580mW×2 at 32Ω with two gain modes, easily driving headphones from low to 600-ohm high-impedance models without distortion. Analog volume potentiometers offer precise adjustment, with 127dB line-out and 132dB headphone-out analog dynamic range. Zero-latency hardware monitoring enables real-time audio preview during recording. Three independent mixers, 6 DAW channels and 4 loopback channels support multi-scene production like streaming, podcasting and music mixing via dedicated control software. Powered by XMOS chip, it supports 44.1kHz–192kHz/24bit high-res audio and fully runs on Windows, Mac, iOS and Android. Dual Type-C ports handle data transmission and power supply; extra power input avoids signal interference for long-term desktop use. The sturdy aluminum alloy housing ensures durability, with dual combo inputs for mic, instrument and line signals plus LED level meters for intuitive signal monitoring.
