The H4N On-Camera DSLR Audio Kit
is a B&H Kit
that provides the new breed of "DSLR" videographers a means of attaching an audio recorder to their camera for dual system audio recording (also applicable for mirrorless cameras).
Aside from the Zoom
recorder, the kit includes an accessory shoe adapter, a pair of headphones for monitoring audio levels, a windscreen for the microphones to cut down on wind noise, and an extra memory card.
Many professional DSLR cameras have unbalanced stereo microphone level audio inputs on a mini TRS 3.5mm jack. The included cable features a -25dB pad attenuator on both audio channels to reduce the line level output (-10dBV) to the camera's microphone input level.
