OTG Direct mobile connection
1、Direct mobile phone connection
You only need an OTG USB cable to directly connect to your mobile phone for live stream, achieving lossless sound quality transmission.
2、Digital transmission distortion: -130dB Dynamic range: 138dB
Note: The audio Interface needs auxiliary power supply when mobile phone OTG is directly connected.
3、Optimize mobile phone live stream with PC synchronization
You can connect to a computer while using E2x2 OTG to livestream on mobile phone. Using the DAW to optimize the voice synchronously, you can also make the sound from live stream more clearer and melodious.
4、Dual mobile phone livestream
You can easily connect another phone to play accompaniment or audio material when one phone is on livestream. What's more, there are dual phone livestreams synchronously, expanding your audience base and making live stream interaction more vivid and interesting.
5、Ultra-linear microphone preamp module
The E2x2 OTG is equipped with a self-developed Ultra-linear microphone preamp module with an EIN as low as -130.5dBu. Even at the maximum volume setting, the E2x2 OTG can maintain extremely low background noise, ensuring that every detail in your recording is perfectly captured.This ultra-linear design ensures that the audio signal is transmitted precisely enough to record clear, transparent sound.
6、Directly connect the condenser microphone
Equipped with 48V phantom power switch, E2x2 OTG is perfectly compatible with condenser and dynamic microphones.
7、Low noise reference voltage module
TOPPING's unique LNRD module provides reference-level stable power supply for the AD/DA chip, further unleashing the chip's performance limit to ensure the purity of audio transmission.
Input DNR（ADC）115dB
Output DNR（DAC）115dB
ADC THD+N<0.0003%
8、Powerful performance Customized headphone amplifier
With only 0.9uVrms of noise floor and 1-ohm output impedance, the NFCA-LE headphone amplifier module frees high sensitivity monitoring headphones from distortion and noise.
The E2x2 OTG offers two gain adjustments, a high gain of up to +17dBu, and a powerful output of 580mW x 2@RL=32Ohm. This combination allows the E2x2 OTG to easily drive professional headphones with impedances up to 600 ohms.
9、Zero-latency hardware monitoring system
The zero-latency design allows you to monitor audio effects in real time during recording or mixing.
10、Freeing dynamic range with analogue volume control
Line Out analogue dynamic range: 127dB
Headphone Output analogue dynamic range: 132dB
An analog Potentiometer is used for volume control of the Line Out and the headphone amplifier, allowing you to control the volume more accurately.
11、Independent mixer control
Equipped with four 12-channel input mixers, the E2x2 OTG allows you to easily adjust and control audio effects for precise audio management. In addition, its 8 DAW channels and 6 LoopBack channels are designed to meet your diverse creative needs for recording, mixing and playback.
12、Optical output brings more creation
The E2x2 OTG supports optical (SPDIF) output and supports a sampling rate of 44.1kHz-192kHz/24bit. In the control center, the SPDIF output audio content can be flexibly selected. The E2x2 OTG can be used with various decoding devices that support optical input to achieve more diverse scenario extensions.
13、Full support for major OS and high specification audio
E2x2 OTG adopts the XMOS chip and is fully compatible with Windows, Mac, iOS, Android and other operating systems. It supports high-specification audio recording and playback from 44.1kHz/24bit to 192kHz/24bit, which brings you more diversified ways to create music.
14、Three Type-C ports
Using Type-C for transmission and power supply.
It is recommended to connect the auxiliary power connector if the E2x2 OTG is frequently fixed to a desktop or if 48V phantom power is required to further avoid signal interference.
Note: External power supply is recommended when using with a phone. A specific cable is recommended when using the OTG function for livestreaming.
