Definitive Audio Inpulse 12 Ba DSP

A Speaker Designed for Mobile Sound Reinforcement, from Speech to DJ Sets

With its 12-inch format and bi-amplified design, the INPULSE belongs to the family of all-in-one active speakers designed for quick setup: plug in, select a DSP mode, adjust the level, and you're ready to go. The injected polypropylene enclosure ensures durability for performances while keeping weight manageable (13 kg) and ease of handling thanks to recessed handles and wheels.

Who Is It For and What Are Its Uses?

The INPULSE is aimed at musicians, DJs, hosts, associations, and service providers who want a portable PA speaker capable of covering various contexts: rehearsals, small stages, classes, conferences, playlist playback, outdoor or indoor events. The "normal/monitor" selection allows use both on a stand and as a stage monitor, while Bluetooth and the 3.5 mm mini-jack input simplify quick setups with smartphones, tablets, or computers.

Built-in DSP: Useful Settings Without Complexity

The integrated DSP includes essential features to adapt the speaker to your source and environment. The 4 programs (MUSIC, LIVE, SPEECH, and DJ) provide an immediate processing base, and the 3-band equalization (bass, mid, treble) allows fine-tuning in seconds depending on the room, microphone, or musical style.

Filtering, Delay, and User Comfort

The filtering adjustment (80 Hz, 100 Hz, 120 Hz, or 150 Hz) helps clean up the low end, especially when you want more vocal clarity or are working with a second bass source. The Delay function (up to 16 ms) is useful for aligning sound in a space, and display options (front panel LED ON/OFF, screen brightness and contrast) improve readability depending on the stage environment.

Complete Connectivity: Mics, Instruments, Players

With two combo XLR/6.35 mm Jack inputs, you can easily connect a microphone or line source. A third input combines RCA, 3.5 mm stereo mini-jack, and Bluetooth TWS, ideal for music playback. The LINK output on a male XLR allows daisy-chaining a second speaker, while the wireless Bluetooth stereo link (TWS) enables pairing two INPULSE speakers without an audio cable between them, within the announced range of 20 m.
