EP–2350 FX–MIC

Product Introduction

1. Definition: The EP–2350 FX–MIC is a standalone, handheld digital performance microphone and vocal effects processor. It belongs to the technical category of portable, all-in-one vocal processing hardware designed for live performance and studio creativity.
2. Core Value Proposition: It exists to empower vocalists, producers, and live performers by consolidating vocal effects, sample triggering, and parameter modulation into a single, portable handheld unit. Its primary value is enabling dynamic, hands-on vocal shaping and sample performance directly from the microphone itself, eliminating the need for external pedals or software in a live setup.

Main Features

1. Built-in Multi-Effects Engine: The microphone integrates four distinct voice effects: Echo, Echo+Spring (a combination of delay and spring reverb emulation), Pixie (a pitch-shifting effect), and Robot (a vocoder-style effect). These are not simple filters but dedicated DSP algorithms processed in real-time on the device's internal hardware.
2. Onboard Sample Player with User Loadable Slots: It features a 4-sample bank that can be triggered via buttons on the microphone body. Crucially, these four sample slots are user-replaceable. Users can load their own custom WAV files, transforming the mic into a personalized sound effects trigger or percussion instrument.
3. Parameter Modulation Lever and Custom Presets: A dedicated physical lever allows for real-time, tactile modulation of effect parameters (e.g., delay feedback, pitch amount). Furthermore, users can build and save custom effect chains and parameter states by editing a simple JSON configuration file, offering deep, programmable customization beyond the factory presets.
4. Dual-Power and Connectivity: Designed for maximum portability, it operates on 2x AAA batteries or via USB-C power. It outputs audio via a fixed, attached 3.5mm curly cable, providing a direct line-out to mixers, recording interfaces, or compatible gear like the Teenage Engineering EP–133 K.O. II sampler.

Problems Solved

1. Pain Point: It solves the problem of cumbersome live vocal setups that require separate microphones, effects pedals, and sample triggers, which involve complex cabling, power supplies, and stage footprint. It also addresses the need for quick, inspirational vocal processing without booting a computer or configuring a DAW.
2. Target Audience: Key user personas include live electronic musicians and vocalists, bedroom producers seeking tactile hardware, podcasters and streamers wanting real-time voice effects, and gear enthusiasts who value portable, customizable tools. It is particularly appealing to users of Teenage Engineering's ecosystem (like the OP–1 Field or EP–133 K.O. II).
3. Use Cases: Essential for live looping performances where triggering samples and applying vocal FX must be immediate; for mobile recording sessions where portability is key; for adding creative vocal textures in electronic music production; and as a standalone performance instrument for experimental sound design.

Unique Advantages

1. Differentiation: Unlike traditional microphones or even most USB podcasting mics, the FX–MIC is an instrument-grade effects processor in a mic body. Compared to using a smartphone app, it offers dedicated, latency-free hardware controls. Versus a pedalboard setup, it is vastly more integrated and portable.
2. Key Innovation: Its core innovation is the fusion of a quality condenser microphone capsule with a fully programmable, performance-oriented digital signal processor (DSP) and sample engine in an ergonomic, self-contained form factor. The ability to customize both samples and complex effect presets via a user-accessible JSON file is a uniquely open and technical approach for a product in this category.

Frequently Asked Questions (FAQ)

1. Can you use the EP–2350 FX–MIC as a regular USB microphone for recording? No, the EP–2350 FX–MIC does not have USB audio functionality. It is an analog microphone with a built-in processor and outputs a processed signal via its 3.5mm line-out cable, which must be connected to an audio interface, mixer, or recorder with a 3.5mm input.
2. How do you load your own samples onto the FX–MIC? You load custom samples onto the EP–2350 FX–MIC by connecting it to a computer via USB-C, where it mounts as a storage device. You then drag and drop your own WAV files into the designated sample folders, replacing the factory sounds.
3. What is the purpose of the JSON file for effects presets? The JSON (JavaScript Object Notation) file allows advanced users to manually define and save custom effect presets. By editing this text file, you can chain effects, set precise parameter values (like delay time or pitch shift intervals), and create complex setups not available from the factory, enabling deep sound design customization.
4. Is the EP–2350 FX–MIC compatible with other gear besides Teenage Engineering products? Yes, absolutely. While it pairs seamlessly with the EP–133 K.O. II, its standard 3.5mm line-level output makes it compatible with any audio setup, including portable recorders, audio interfaces, mixers, smartphone adapters, or the auxiliary input on speakers and amplifiers.
5. What type of batteries does the FX–MIC use, and what is the battery life? The EP–2350 FX–MIC is powered by 2x AAA batteries. Official battery life specifications are not provided, but life will vary significantly based on usage of the effects, sample playback, and whether the lever is actively engaged. Using USB-C power is recommended for extended sessions.
