Product Introduction

General Introductions

The SARAMONIC SR-PAX2 is a two-channel active audio mixer with preamplifier and phantom power, specially designed for mirrorless digital camera, Blackmagic Design pocket cinema camera and DSLR camera with a microphone jack. It is a compact and lightweight mixer ideal for recording professional-quality audio from two sources and mixing them into your camera. It attaches to the base of a camera, and a threaded socket on its base allows for mounting on a tripod or case.

With two sets of inputs, the SR-PAX2 accepts signals from a wide variety of mic or line level sources such as balanced XLR microphones, 3.5mm microphones, wireless microphones and external audio mixers. The 3.5mm inputs are also ideal for connecting audio devices with a 3.5mm output such as a smart phone or an MP3 player. The input levels of each channel can be easily controlled with the dual gain control knobs. The cold shoe on the side gives you space to mount and move other equipment. A phone jack allows you to monitor the audio in real time. The SR-PAX2 makes your recording work much easier.

   When using self-powered microphones and wireless systems, set to MIC for 20dB gain or set to LINE for 0dB gain.
   When using other audio devices, please set to LINE.
   When using microphones operating on phantom power, please set to PH for phantom power.
   Note: Please DO NOT select phantom level when recording with microphones that do not operate on phantom power, like wireless receivers, mixing boards or any unbalanced device, because it may damage both the mixer and audio device.
