Topping has launched the new E2x2, E4x4 and E1x2 USB audio interfaces.
Topping E2x2
Topping E2x2 is an excellent audio interface designed for musicians and audio professionals. This interface offers a very high level of performance for perfectly transparent recording and playback.
The NFCA-LE headphone amplifier module in Topping E2x2 has a noise level of only 0.9uVrms and an output impedance of 1Ω, allowing high-sensitivity headphones to be used without distortion and noise.
The Topping E2x2 has two gain settings, high gain up to +17dBu and an output power of 2x580mW into 32Ω. The combination of such high gain and significant output power means that the Topping E2x2 can easily accompany professional high-impedance headphones, up to 600Ω.
Equipped with three 8-channel input mixers, the E2x2 allows you to easily configure and control audio effects. Moreover, 6 DAW channels and 4 LoopBack channels are designed to adapt to different recording, mixing and playback needs.
Equipped with 48V phantom power and a switch to enable or disable phantom power, the Topping E2x2 is ideally compatible with condenser and dynamic microphones.
Zero latency design allows you to monitor audio effects in real time while recording or mixing, improving productivity.
Topping E2x2 is equipped with a superior USB XMOS interface, compatible with Windows, Mac, iOS and Android operating systems. It supports high-resolution audio streams for recording and playback, up to PCM 24-bit 192 kHz.
The Topping E2x2 components are protected by a strong and durable aluminum alloy chassis that is discreet and modern.
The Topping E2x2 features the brand’s ultra-linear mic preamp module, which has an input noise as low as -130.5dBu. Even at maximum volume, the E2x2 can maintain very low noise levels, ensuring every detail of your recording is captured perfectly. The ultra-linear architecture ensures that the audio signal is transmitted with sufficient precision for perfectly clean and transparent recording.
Topping’s unique LNRD module provides a stable power reference for the AD/DA converter chip, unlocking the chip’s full potential for high-purity audio transmission.
The line-out and headphone-out volume controls use an analog potentiometer, providing excellent precision for easy control of audio levels.
