From Amazon

Main features

● If you remove the camera mounting bracket, it can be used as a high quality sound stand-alone portable recorder.

※ Camera and microphone and stands are not included.

● Remote control of single lens reflex cameras supported by START / STOP recording is possible with infrared ray emission and wired recording.

* Remote by infrared is assumed to be used with the camera installed in the camera mount bracket of the DC - R 302 main unit.

* Depending on the camera used, optional EX - RT1 and ET - RT1 are required.

Remote control compatible model

■ Infrared Remote (Canon only)

· EOS 5D MK2

· EOS 5D MK3 · EOS 7D · 60D · 70D · KISS 5X

* For cameras other than EOS 5D MK2, the infrared receiver is in the recessed part of the grip, so an optional remote control unit EX - RT1 is required.

■ Wired remote * Optional remote control unit EX - RT1 and remote cable ET - RT1 series are required.

Corresponding remote cable (ET-RT1 series) and operation check model

ET-RT 1 C: Canon: EOS 5 DMK 3, EOS-1 D X

· ET-RT1N: Nikon (10 pin type): D800, D800E, D4

· ET-RT 1 N 2: Nikon (6 pin type): D 7000, D 600, D 610

· ET-RT 1 P: Panasonic: DMC-GH 2, DMC-GH 3

* Depending on the specification of the camera, when using GH1 / GH2 remote, external microphone input can not be used.

● Input corresponds to microphone to line level.

Limiter and HPF are mounted on each channel.

Reduced distortion due to excessive input and unnecessary bass components.

* Reference input level at line is -10 dBu.

It is not + 4 dBu for business standards, please be careful.

● Also supports USB AUDIO input / output.

It can also be used as an audio interface for PC.

* USB AUDIO is a function added in firmware version 1.10 of DC - R 302.

* It works with OS standard driver of Windows XP / Vista / 7 and Mac OS X 10.6 or higher.
