Sony ECM-W3 Help Guide - Page 4

Movies recorded with 24-bit audio may not be played back normally on devices or software incompatible with 24-bit audio, resulting in unexpectedly loud volumes or no sound. If your camera is not compatible with the digital audio interface of the Multi Interface Shoe, set the switch to "ANALOG." When the message "This accessory is not supported by the device and cannot be used." is displayed on the camera, set the switch to "ANALOG." If this does not help, see here. When a TRS audio cable with the 3.5 mm diameter plug (commercially available) is connected, the receiver outputs analog signals via the cable. When a device with a USB audio input capability is connected, the receiver outputs digital signals. When you do not intend to use the receiver, set the switch to "OFF" to conserve the battery power. 2. Mode switch (SEP/MIX) (ECM-W3) By selecting a receiver mode with this switch before you start video recording with the camera, you can make recordings with audio from either of the two microphones individually as the left or right channel audio; or recordings with mixed audio from the two microphones. 3. Multi Interface foot 4. LINK (LINK1/LINK2) lamp (ECM-W3) LINK lamp (ECM-W3S) Indicates the connection state between the receiver and the microphone.

The number "1" indicates the microphone No. 1; and the number "2" indicates the microphone No. 2. To identify which microphone connection is active with the receiver, check the state of the LINK1 lamp for the microphone No. 1 and the LINK2 lamp for the microphone No. 2 on the receiver.
