• Quick Start: simple setup to start recording in minutes, without complex installation.

A Bluetooth Bridge Dedicated to Interview Recording, at the Heart of a Modern Workflow

The BTA-2 fits into a current audio production logic: create content, capture conversations, and publish quickly, even when your guests are not physically present. Rather than relying on a makeshift adaptation chain, it centralizes the wireless connection to the phone and helps you integrate remote communication into a recording environment.

The benefit is immediate for creators who alternate between studio, travel, and home studio: a compact, call-oriented solution capable of integrating into lightweight setups as well as more complete configurations, as long as you have an input compatible with TRRS.

Who Is the BTA-2 For and When to Use It?

The BTA-2 is particularly suited for podcasters, journalists, streamers, content creators, and production teams who want to record remote interviews via a smartphone. It allows the use of common applications (voice calls, online meetings, messaging, videoconferencing) to connect with a guest, then capture the audio signal for recording.

It is also well suited for formats where responsiveness matters: pre-interviews, "hot" reactions, mobile shows, or capsules recorded between sessions. Compared to a strictly wired connection to the phone, the Bluetooth approach can offer more flexibility in placement and reduce clutter, while maintaining a simple connection scheme.

Connectivity and Operation: A Clear Setup to Get Straight to the Point

Two TRRS Connectors to Separate Audio and Power

The BTA-2 features two distinct connections designed to avoid confusion during setup. On the right, a TRRS 3.5 mm connector carries the audio signal. On the left, a TRRS 2.5 mm connector is dedicated to power supply. This separation improves cable management clarity and helps establish a reproducible workflow, especially useful when chaining multiple takes.

Natural Integration with Calling Apps

Once paired, you can use "any app" compatible with calls (voice or videoconference) to conduct the interview: Skype, Zoom, the Phone app, and many others. This allows you to keep your habits (accounts, contacts, call history) and adapt your method to each guest without imposing a single solution.

Audio Best Practices (Latency, Levels, Stability)

As with any Bluetooth connection, the stream may introduce a perceptible latency depending on the app and device used. For a more comfortable experience, favor a monitoring method consistent with your setup, and take a few moments to validate levels before the final recording. The BTA-2's simple configuration precisely facilitates these quick checks: pairing, communication test, then start recording.
