The JuicedLink Riggy Micro Low-Noise Preamplifier is a straightforward, miniature and flexible microphone preamplifier for use with DSLR cameras that are rich in audio features, such as the Nikon D800 and Canon 5DMKIII. Cameras such as the D800 and 5DMKIII feature headphone outputs for confident and direct audio monitoring, AGC disable and onboard metering, allowing JuicedLink to design a more compact and straightforward preamp in the RM333.There are 3 built-in XLR inputs and a single 1/8" (3.5mm) stereo output, input gain control, 48V and 12V phantom power. The RM333 is capable of alkaline or LiPolymer battery operation and its small, lightweight enclosure allows for flexible mounting and room for accessories. Simultaneously "rig" optional accessories onto the top and side of the RM333 Riggy Micro for flexible mounting options unheard of from a preamplifier this small.
