ESI UGM192

UGM192: the "pocket studio" approach in the ESI range

Designed for musicians who want to record anywhere without hassle, the ESI UGM192 positions itself as a 2-channel interface focused on guitar and vocals, prioritizing portability without sacrificing conversion quality. While many mobile solutions settle for "emergency" use, the UGM192 aims for a coherent audio chain: dedicated microphone preamplification, Hi-Z instrument input suited for guitar pickups, and a stereo output designed for both headphone listening and playback. Its compact size and metal casing make it a tool built for travel, while perfectly fitting into a home studio environment.

Who is it for and what are its uses?

The UGM192 is aimed at guitarists, singers, singer-songwriters, and content creators who want to capture a clean take quickly with minimal gear. In practice, you can record an electric guitar (or bass) via the Hi-Z input while plugging in a dynamic or condenser microphone into the mic preamp, then immediately listen to your mix through headphones. It is also a relevant solution for working on sounds in real time (amp simulators, effects, vocal processing) and silent rehearsals, while maintaining a lightweight setup for travel, impromptu sessions, or home studios.

Key Features: Quality, Monitoring, and Compatibility

24-bit / 192 kHz conversion and 114 dB dynamic range

The 24-bit / 192 kHz A/D and D/A conversion preserves precision on pick attacks, vocal dynamics, and percussive playing transients. The stated dynamic range of 114 dB helps achieve a clearer signal with better-controlled background noise, especially useful when layering takes (double guitars, harmonies, stacked vocals) or applying compression and equalization.

Hi-Z instrument input: the right starting point for credible guitar tone

The Hi-Z instrument input is designed to receive an electric guitar directly, with an impedance matched to avoid a flat or muffled sound. You can then shape the sound in your DAW with amp simulations and effects, or record a clean DI signal for later reprocessing. This is a major advantage for headphone work, apartment rehearsals, or preparing demos without an amp mic.

Microphone preamp with switchable 48 V phantom power

The built-in microphone preamplifier allows connection of a professional microphone, whether dynamic or condenser. The switchable 48 V phantom power gives you the flexibility to use a condenser mic for vocals, an acoustic guitar (with a suitable mic), or more detailed takes. The balanced 6.3 mm jack connector facilitates integration into compact setups with a simple and direct approach.

Monitoring and listening: stereo line/headphone output

The stereo output serves both playback and real-time input monitoring. Practically, you connect headphones, record, and listen to your signal and playback without needing additional equipment. This "all-in-one" logic is ideal for composing, recording, and quickly correcting takes, whether on a computer or a compatible mobile setup.

USB 3.1 compatible with USB 2.0 and audio drivers

The UGM192 connects via USB 3.1 while remaining compatible with USB 2.0, simplifying use across a wide range of machines. On the software side, announced compatibility with ASIO 2.0, WDM, and MME via the EWDM driver (Windows) as well as Core Audio (macOS) allows smooth integration into most DAWs, with latency management suited for recording and real-time playing.

A true mobile logic, including external power supply

For recordings outside the studio, the UGM192 can be powered via an optional external battery, enhancing its appeal for field recordings, rehearsals, or creation on the move. You keep a simple chain: guitar, microphone, headphones, interface, and host device, without heavy infrastructure.
