Definitive Audio Inpulse 8 Ba DSP

A compact speaker designed for modern sound reinforcement, balancing versatility and mobility

Battery-powered compact active speakers have established themselves as a simple solution for hassle-free sound reinforcement: quick setup, accessible adjustments, and sufficient performance for light configurations. With its 8-inch format and integrated DSP, the INPULSE fits this "all-in-one" logic: a self-contained speaker capable of adapting to various uses (music, voice, DJ) while maintaining a compact footprint.

For which uses and musicians is this speaker made?

The INPULSE is aimed at musicians, DJs, and hosts looking for a portable active speaker for small gatherings, rehearsals, classes, speeches, or music playback indoors or outdoors. Its "monitor" mode and 90 by 60 dispersion also make it a practical solution for stage monitoring or occasional reinforcement, where clear sound projection and quick setup are needed.

Thanks to its multiple inputs, it easily integrates into varied setups: microphone via XLR, line source via 6.35mm Jack, audio player via RCA, or smartphone via 3.5 mm mini-jack and Bluetooth. You save time during setup while retaining real connection flexibility.

Built-in DSP and connectivity: effective settings without complexity

Presets adapted to content

The DSP offers 4 programs (MUSIC, LIVE, SPEECH, and DJ) to quickly tailor the response curve according to your source. Whether you seek balanced music playback, clearer voice, or a more dynamic sound, these modes provide a reliable base, especially when setup time is limited.

Equalization, filter, and delay: essentials to adapt to the environment

For fine-tuning, you have 3 corrections (bass, mid, treble) and a selectable filtering setting at 80 Hz, 100 Hz, 120 Hz, or 150 Hz. This filter is particularly useful if you pair the speaker with a subwoofer or want to clean up the low end in a resonant room. The delay up to 16 ms allows aligning the sound in certain configurations (two sound points, reinforcement, or managing perceptible delay).

User comfort: screen, indicators, and readability

Ergonomics are enhanced by a screen with adjustable brightness and contrast, as well as a front LED (activatable or deactivatable) to stay discreet on stage. The charge and battery status indicators help anticipate usage, especially for mobile applications.

Bluetooth 5.2 and TWS: wireless stereo playback

The Bluetooth 5.2 connection allows linking a compatible source up to 20 m (depending on environment). The speaker also includes a Bluetooth wireless stereo link (TWS) to connect two INPULSE speakers together up to 20 m, providing wider sound coverage and a stereo image without an audio cable between the two points.
