Product Introduction

General Introductions

The Saramonic SR-PAX1 is a two-channel audio mixer with phantom 
power, specially designed for mirrorless digital camera, DSLR camera and 
camcorder 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. 

With two sets of inputs, the SR-PAX1 accepts signals from a wide variety 
of mic or line level sources such as balanced XLR microphones, wireless 
microphones, guitars, or any musical instruments with a 6.35mm 
connector. 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 control knobs. 
A phone jack allows you to monitor the audio in real time. The SR-PAX1
