Professional Multi-User Monitoring for
Podcasts & Streaming: Tailored for podcasters, streamers, and creators, the HA4D allows up to 4 users to monitor audio simultaneously in real-time. Whether it's a co-hosted session, group interview, or classroom setup, everyone stays perfectly in sync. 4 Independent Channels with
Instant Mute Switches: Take full control of your audio. Each of the 4 output channels features a dedicated volume knob and an individual mute switch. Users can adjust their own levels or silence their feed instantly without affecting others. Crystal Clear Audio & High
Dynamic Range: Experience professional-grade sound. Engineered with high-quality circuitry, the HA4D delivers a 100 dB dynamic range and ultra-low distortion, ensuring clean, transparent, and detailed audio even at high output levels. Flexible USB-C Power for
On-the-Go Sessions: Powered via a universal USB-C port, the HA4D eliminates the need for bulky proprietary adapters. Simply connect to a power bank, wall charger, or PC for a clutter-free setup in home studios or mobile recording environments.
Pro-Tip for Noise-Free Performance: To ensure the cleanest audio signal and avoid potential ground loop interference (hum or buzz), we recommend powering the HA4D via a separate power bank or USB wall charger rather than the same laptop used for your audio source. Compact, Intuitive
& Road-Ready Design: The user-friendly interface is designed for fast, tactile adjustments during live recordings. Its sleek, lightweight footprint fits easily into any gig bag, making it the perfect tool for collaborative creators on the move
