TOPPING E2X2 - 2x2 USB Audio Interface | Professional Audio Interface | Ultra-Linear Mic Preamp | NFCA-LE Headphone Amp | Zero-Latency Monitoring
The TOPPING E2X2 is a high-performance professional USB audio interface designed for music producers, streamers, and audiophiles, redefining the sound quality standard for entry-level interfaces. It not only features high-resolution recording specifications up to 192kHz/24bit but also incorporates top-tier technology from TOPPING's years of deep cultivation in the Hi-Fi field. The E2X2 is equipped with an exclusively developed ultra-low noise microphone preamp, boasting an astonishing -130.5dBu Equivalent Input Noise (EIN), ensuring your recordings are pure and flawless, capturing every subtle emotional fluctuation.
Beyond excellent recording quality, the E2X2 features a built-in audiophile-grade NFCA-LE headphone amplifier module, providing powerful output up to 580mW (32Ω). Whether using high-sensitivity in-ear monitors or high-impedance professional over-ear headphones, it drives them with ease and reveals ultimate details. Paired with the LNRD Low Noise Reference Driver module and professional Loopback functionality, the E2X2 becomes a comprehensive solution combining studio-grade sound quality with streaming convenience, perfectly supporting platforms like Windows, Mac, iOS, and Android.
Core Advantages & Application Scenarios
Ultra-Linear Mic Preamp
The E2X2 is equipped with TOPPING's proprietary ultra-linear microphone preamplifier, with an Equivalent Input Noise (EIN) as low as -130.5dBu. This means even when gain is turned up, the noise floor remains extremely low, perfectly restoring the delicate sound quality of condenser microphones and providing a crystal-clear signal source for vocal recording and instrument pickup, far exceeding the performance of products in its class.
NFCA-LE High-Performance Headphone Amp Module
Inheriting TOPPING's technical advantages in headphone amplification, the E2X2 features the NFCA-LE module, achieving an ultra-low noise floor of just 0.9uVrms and an ultra-low output impedance of 1Ω. Whether it's extremely sensitive IEMs or hard-to-drive full-sized headphones, you get a distortion-free, dynamically vast monitoring experience. It features High/Low gain switching, with a maximum output level of +17dBu and single-ended output power up to 580mW x 2 @ 32Ω.
LNRD Low Noise Reference Driver Technology
To ensure optimal performance of the AD/DA conversion chips, the E2X2 utilizes a unique LNRD (Low Noise Reference Driver) module. This technology effectively filters noise from the USB power supply, providing a reference-grade stable power source for the analog circuits, further unleashing chip potential and ensuring audio purity and stability.
Zero-Latency Hardware Monitoring & Professional Mix Control
The E2X2 supports zero-latency Direct Monitor, allowing singers or musicians to hear their own voices instantly during recording without computer processing. Combined with the dedicated control software (Topping Control Center), users can flexibly control 4 input channels, 6 DAW channels, and 4 Loopback channels, easily realizing complex routing needs for streaming, podcasting, or gaming voice chat.
Dual Type-C Interfaces & Cross-Platform Compatibility
Adopting an XMOS chip solution, it is fully compatible with Windows, Mac, iOS, and Android systems. The back of the unit features dual USB Type-C ports; one for data transmission and power, and the other as an auxiliary power interface. When connecting to mobile devices like phones or tablets, external power can be connected via the auxiliary port to avoid draining the phone's battery, enabling stable, long-duration mobile recording sessions.
