Saramonic SR-PAX1 On-Camera Mixer - Compact Dual XLR Preamps

In this review the Saramonic SR-PAX1 is presented as a compact on-camera mixer for videographers who need to record multiple microphones to DSLR and mirrorless cameras. The bottom line: it is for shooters who want flexible inputs and reliable preamps without a large rig. The SR-PAX1 stands out because it combines two XLR/1/4' combo preamps with phantom power plus three 1/8' inputs in a small package, making it a practical choice when a camera lacks professional audio inputs or a headphone jack.

Key Features

• Dual XLR/1/4' combo inputs: Accepts two professional microphones or line sources and supplies +48V phantom power for condenser mics.
• Three 1/8' preamp inputs: Lets you add lavaliers or consumer-level mics with 5V plug-in power for flexible multi-source recording.
• Dedicated headphone output: Provides real-time monitoring when the camera has no headphone jack so you can check levels and sound quality on set.
• Compact camera mount: Small, solid construction with three shoe mounts to attach mics, lights or wireless receivers directly to the unit.
• Mixing and adaptation: Mixes different mic and line level sources down to a 1/8' camera input, allowing a variety of devices to be recorded together.

Who It's For

The SR-PAX1 is aimed at run-and-gun filmmakers, wedding and event videographers, and content creators who need professional audio inputs on cameras with only a single mini input. Its combination of XLR preamps and mini inputs makes it especially useful for shoots that use both shotgun mics and lavaliers at the same time.

Those who rely on multi-track recording into external recorders, need heavy-duty studio routing, or require built-in camera timecode should look elsewhere; the SR-PAX1 is engineered for on-camera convenience and flexible connections rather than large-scale location mixers.

Pros & Cons

Pros

• Provides two professional XLR/1/4' preamps with +48V phantom power for condenser microphones.
• Three 1/8' inputs with 5V plug-in power add compatibility with consumer and lavalier mics.
• Dedicated headphone output allows accurate monitoring even when the camera lacks one.
• Compact, well-built unit with three shoe mounts for mounting microphones and accessories.

Cons

• Mixes down to a single 1/8' output, so it is not a multi-track recorder and cannot send isolated channels to the camera.
• Not a replacement for larger location mixers when many simultaneous inputs or advanced routing are needed.
