As a freelance music producer based in Lisbon, I frequently travel between studios, cafes, and client meetings. My workflow relies heavily on my iPhone and a portable DAW app like GarageBand and Cubasis. Before switching to the E2x2, I used a basic USB audio interface that required a power bank and a USB-C to USB-A adapteradding bulk and complexity. The E2x2 solved all of that. I now connect my iPhone directly to the E2x2 via USB-C, and it powers the interface without needing an external battery. The interface automatically detects my phone and activates the audio drivers. I can record vocals, guitar, and MIDI via USB, monitor through my headphones with zero latency, and even stream live to platforms like Twitch using LoopBack channels. Here’s how I set it up and use it daily: <ol> <li> Connect the E2x2 to my iPhone using a USB-C to USB-C cable. </li> <li> Open the Cubasis app and select “E2x2” as the audio input/output device. </li> <li> Enable “LoopBack” in the app settings to route internal audio (e.g, playback from the DAW) to the output for streaming. </li> <li> Plug in my Shure SM58 into Input 1 and my electric guitar into Input 2. </li> <li> Use the headphone output with my Sennheiser HD 600s for real-time monitoring. </li> <li> Record a vocal take while applying reverb via a pluginno latency, no dropouts. </li> </ol> The E2x2’s ability to handle multiple audio streams simultaneously is critical. I often record a vocal track while playing back a MIDI backing track and routing both to the output for monitoring. The 6 LoopBack channels allow me to send the DAW’s internal mix to a streaming app without needing a separate audio interface. <dl> <dt style="font-weight:bold;"> <strong> OTG (On-The-Go) </strong> </dt> <dd> OTG is a USB standard that allows a mobile device (like a smartphone) to act as a host and communicate with peripherals such as audio interfaces, keyboards, or storage devices. This eliminates the need for a computer. </dd> <dt style="font-weight:bold;"> <strong> LoopBack </strong> </dt> <dd> LoopBack is a feature that allows audio signals from a DAW or app to be routed back through the interface and sent to another application (e.g, streaming software, enabling live audio mixing and broadcasting. </dd> <dt style="font-weight:bold;"> <strong> DAW Channels </strong> </dt> <dd> These are the number of independent audio input/output paths available within a DAW that can be used for recording, monitoring, or routing.

I run a small podcast studio from my apartment in Berlin, where I record interviews with musicians and producers. My previous interface was a budget USB audio interface with 16-bit/48kHz resolution and noticeable background noise. When I switched to the E2x2, the difference was immediate. I recorded a 45-minute interview with a jazz guitarist using the E2x2, connecting his microphone via XLR to Input 1 and his guitar via 1/4 to Input 2. I used the built-in preamps with +48V phantom power for the condenser mic. The audio was clean, with no hiss or distortioneven at high gain levels. The E2x2’s preamps are designed with low-noise circuitry and high headroom, which means they can handle both quiet vocals and loud guitar signals without clipping. I recorded a vocal at -18dBFS and boosted it in post to -6dBFSno artifacts, no noise floor. Here’s how I ensure professional audio quality every time: <ol> <li> Set the sample rate to 192kHz in both the E2x2 control panel and my DAW (Logic Pro X. </li> <li> Use the E2x2’s internal clock to avoid jitter and sync issues. </li> <li> Enable the “High-Resolution” mode in the interface’s firmware (via the Topping app. </li> <li> Use balanced TRS cables for all connections to reduce interference. </li> <li> Record in 24-bit depth to preserve dynamic range and detail. </li> <li> Apply minimal EQ and compression during recordinglet the interface do the work. </li> </ol> The E2x2 also features a dedicated SPDIF output, which I use to send a clean digital audio signal to my external DAC for final mastering. This ensures no analog degradation during the final stage. <dl> <dt style="font-weight:bold;"> <strong> 24-bit/192kHz Audio Conversion </strong> </dt> <dd> 24-bit resolution provides a dynamic range of up to 144 dB, while 192kHz sample rate captures audio frequencies beyond human hearing (up to 96 kHz, resulting in more accurate and detailed sound reproduction. </dd> <dt style="font-weight:bold;"> <strong> Low-Noise Preamps </strong> </dt> <dd> Preamps amplify weak audio signals (like from microphones) without adding significant noise. The E2x2’s preamps have a signal-to-noise ratio of 115 dB, which is excellent for professional use. </dd> <dt style="font-weight:bold;"> <strong> Internal Clocking </strong> </dt> <dd> Internal clocking ensures stable timing in audio data transmission, reducing jitter and improving overall audio clarityespecially important in multi-track recording. </dd> </dl> | Audio Parameter | E2x2 | Competitor A (Budget) | Competitor B (Mid-Range) | |-|-|-|-| | Bit Depth | 24-bit | 16-bit | 24-bit | | Sample Rate | 192kHz | 48kHz | 96kHz | | SNR (Signal-to-Noise Ratio) | 115 dB | 90 dB | 105 dB | | Jitter Performance | <100 ps | > 500 ps | <200 ps | | Phantom Power | +48V (XLR) | +48V (XLR) | +48V (XLR) | | Clock Source | Internal & External | Internal only | Internal only | I’ve used the E2x2 to record a full EP with three vocalists and two guitarists.
