This adapter is designed to easily attach balanced or unbalanced type microphones to this camcorder (condenser type microphones require their own power as the adapter does not supply phantom power). The low noise preampliﬁers boost the audio level from virtually any microphone to the “sweet spot” for improved signal to noise ratio. The fast acting limiters virtually eliminate distortion from overly hot inputs. The DXA-FX is very easy to set up and use, therefore it requires a minimal amount of fuss. It ﬁts ideally under the Sony HDR-FX1 camcorder and its rugged construction ensures years of use. • Before using this high quality device, please read this operating manual thoroughly to obtain the highest performance. • Please contact us if you have any problems or questions. Front Panel Controls and Indicators Mounting and Connection Mount the DXA-FX securely to the tripod bushing on the under side of your camcorder. Connect the cable from the DXA-FX to the camcorder’s microphone jack. The camcorder’s onboard microphone should now be disabled. Camera Setup Set the audio mode switch on the back of the camcorder to MAN to deactivate the AGC. Turn the AUDIO LEVEL thumbwheel on the camcorder to 3 on the dial. Set the input level on the camera menu to EXT MIC. You are now ready to attach external microphones to the adapter. Adapter Controls and Connectors 1. Power Install a fresh 9 volt alkaline battery in the adapter. Turn on the PWR switch to activate the unit. The center LED should light to indicate good battery power. Turn off power when not in use to conserve battery power 2. MONO / STEREO Switch Set the switch to MONO if using a single microphone. Set it to STEREO when using two microphones. Rear Panel Controls and Connections 4. Limiter Each channel has an independent limiter to prevent distortion caused by excessively hot inputs. We recommend that this switch be activated at all times to ensure clean, distortion free audio. When activated, the corresponding LMT indicator will ﬂash in proportion to the amount of limiting. Set the gain control on the adapter so that the indicators are ﬂashing occasionally. Be sure that the camcorder level is set to 3. The input signal level to the camcorder is set to a maximum of -36dBu regardless of the input level to the adapter. Verify that the red bar on the level meter does not activate, otherwise reduce the gain using the AUDIO LEVEL control on the camcorder. Once the camcorder and adapter gain controls are set correctly, you will be ensured perfect audio levels every time. 5. XLR Inputs The two XLR inputs can accept balanced or unbalanced connections. To convert the input to unbalanced, simply ground pin 1 to 3 on the XLR input cable. 6. Output Cable The attached shielded cable terminates in a gold plated, stereo mini plug connector. Plug this into the microphone jack on your camcorder as described above. 3. Gain Control Each channel of the DXA-FX has a gain control to provide the optimum amount of ampliﬁcation for your particular microphone. Note that even with the gain setting fully counter clockwise for minimum gain, you will still get some audio signal. Set the gain control on the adapter for the desired volume level on the camcorder. Sensitive condenser type microphones like the popular Sennheiser ME66 will require a minimum amount of gain while most dynamic type microphones require maximum amount of gain. Use the level indicator on the camera as a guide. Be sure not to activate the red bar on the level meter to avoid distortion. See the limiter description for information on proper gain setting when the limiter is active. ©2006 BeachTek Inc.
