Introduction
The Azden FMX-DSLR is a 2-channel portable mixer with built-in preamplifiers that will enable you to attach external micro-
phones and other audio gear to any DSLR camera with a built-in mic jack.
The FMX-DLSR uses exceptionally low noise, wide bandwidth preamplifiers for superb audio. It allows you to connect a wide
variety of audio devices including wireless systems, sound boards and professional condenser microphones that require 48V
phantom power to operate.
The FMX-DSLR is equipped with the AGC On/Off switch that will allow you to control the wild swings of the Auto Gain Control
(AGC) that plague most cameras. With the switch in off position, it will reduce noise during quiet moments of recording.
The mixer mounts to the bottom of the camera and can also be mounted to any standard tripod.
Before You Begin
1. These instructions refer to the use of this mixer with the DSLR cameras unless otherwise noted.
2. Always perform a few test recordings and check playback on the camera to be sure that the audio is captured as expected.
Since there is no headphone jack on most cameras, you cannot monitor what is being recorded by the camera.
3. Please read and understand the use of the AGC On/Off feature before using this function.
Setup Guide
1) Install 4 "AA" batteries in the mixer (not included).
2) Mount the FMX-DLSR to the camera using the CAMERA MOUNTING BOLT (○
mixer to the tripod hole on the underside of the camera. Carefully turn the mounting bolt clockwise using a coin from the
bottom panel of the mixer. Make sure the mixer is mounted squarely to the camera. Do not over tighten.
3) Connect the supplied mini-to-mini cable from the OUTPUT jack on the mixer (○
the MIC input jack on the camera is not 3.5mm mini-plug jack, source an appropriate cable that will allow the connection.
4) Set the MIC 1/LINE/MIC 2 SELECTOR (○
5
) to either MIC 1 (XLR) or MIC 2 (mini plug) when connecting microphones or most
wireless receivers, or to LINE when taking a line level feed.
5) Connect audio sources to the mixer.
6) Set the MONITOR SELECTOR (○
8
) to OUTPUT to monitor the audio from the microphones during recording.
7) Set the GAIN switch(es) (○
) to your preference. HI is the normal setting for most microphones. If you are using very sen-
6
sitive condenser type microphones or recording very loud sounds, you may have to set the GAIN switch to LOW to prevent
distortion.
