Roll Camera, Roll Studio-Quality Sound

The ARRI Audio Extension Module AEM-1 bridges the gap between high-end digital cinema and pristine sound acquisition. Designed specifically for the ALEXA 35, this module brings two channels of elite, studio-quality microphone pre-amplification directly into your camera rig. Engineered in partnership with Sonosax—highly regarded for decades of exceptional cinematic audio engineering—the AEM-1 serves as the absolute best solution for shoots that require robust, high-fidelity in-camera audio without the clutter of a separate field recorder.

Elite Engineering and Crystal-Clear Acoustics

Boasting a total dynamic range of 135 dB and less than 0.001% Total Harmonic Distortion (THD), the AEM-1 ensures a transparent, uncolored signal capture. Both balanced TA3F mini-XLR inputs offer independent 48 V phantom power, a +20 dB analog pre-gain stage, phase reversal, and dual-ADC technology. Operators can easily engage a hybrid analog-digital low-frequency cut filter to sweep away wind rumble or motor noise in precise steps from 60 to 320 Hz.

Form and Function Optimized for the Set

Rather than adding bulk to the side of the camera, the AEM-1 features a slimline back-mounting design that interfaces perfectly between the camera chassis and B-mount batteries. This keeps the camera's center of gravity centered, which is essential for handheld, Steadicam, or gimbal work. With its integrated status screen, physical gain knobs, and dedicated headphone volume encoder, setting levels is direct, intuitive, and highly tactile.

Integrated Power and Post-Production Savings

Beyond audio control, the AEM-1 serves as a crucial power expansion block, providing secondary 12 V Lemo and 24 V Fischer ports to supply camera accessories, wireless focus motors, or transmitters. By recording broadcast-ready audio directly onto your camera's high-speed media, the AEM-1 eliminates the tedious time spent in post-production manually syncing separate audio files, keeping your turnarounds rapid and highly efficient.
