Key Features & Benefits
🔹 SM28 Beige Condenser Headsets – Articulate, Discreet Performance
Each SM28 headset features a high‑quality condenser capsule that captures speech and vocals with exceptional clarity. The beige, low‑profile frame stays comfortable and nearly invisible under stage lights or on camera, making it a top choice for theater, presentations, and broadcast.
🔹 Encrypted UHF Bodypack Transmitters – Move Freely, Stay Protected
The robust metal bodypacks transmit on digital UHF with encryption, locking your audio from eavesdropping and RF interference. Enjoy 100-300 meters of stable range — walk the stage, roam the classroom, or lead a fitness class without losing a word.
🔹 Dual Independent Channels – Two Headsets, Zero Compromise
The AD4D receiver provides two independent UHF channels, each with up to 100 selectable frequencies. Two presenters, instructors, or performers can wear the SM28 headsets at the same time with no crosstalk — perfect for co‑hosts, panel talks, or dual fitness demos.
🔹 1U Rack Receiver with Blue LED Dashboard – Complete Control
The black metal 19" 1U chassis integrates effortlessly into any rack system. The bright blue LED display shows frequency, RF/AF levels, and transmitter battery status in real time — so sound engineers and users alike have full visibility from soundcheck to final bow.
🔹 Versatile Solution for Any Speech or Performance
From live theater & stage plays to church services, fitness instruction, school lectures, DJ livestreams, and corporate keynotes — the AD4D SM28 system delivers encrypted, hands‑free audio with simple plug‑and‑play setup.
