Audio-Technica mtu301 manual

Note: If the red Charge Error LED (next to the charging port) is illuminated, this indicates

a charging system error. Causes include: non-NiMH batteries; failed batteries; incorrectly installed batteries; brief interruption in power. Be certain you are using properly installed NiMH batteries and reconnect to begin the charging cycle again.

2.Select a unique channel address in the battery compartment of each mtu301 Body-pack Transmitter. (1-7 for the first aci707 audio control interface unit used; 8-14 for the second aci707 unit). (See Channel Address Selection, page 6.)

3.Connect your microphone to the audio input jack on the top of the mtu301 Body-pack Transmitter. (Use any Audio-Technica lavalier or headworn wireless microphone whose product number ends with a “cW”.) The wireless microphone’s cable connector latches automatically when inserted into the mtu301 audio input jack. To unlatch and remove the connector, pull up on the connector’s knurled metal collar.

4.Turn on the power switch on the top of the mtu301. The Power LED on the top of the mtu301 will glow blue. (See Power On/Off, page 6.)

5.Confirm link status. If the mtu301 Body-pack Transmitter is properly linked, the UWB Link LED in the battery compartment will glow blue, and the top green light on the corresponding aci707 channel will light.

6.Confirm mute/live audio status. When the audio is on, the Live Audio LED on the top of the mtu301 glows green. To change mute status, depress the body-pack transmitter’s push-button switch. When the audio is muted, the Mute LED glows red. (See Audio/Mute LED, page 6.)

7.Confirm battery status. Low battery is indicated by blinking blue power light (at the top of the mtu301). (See Low Battery Warning, page 6.)

8.With the aci707 on and connected as desired, the drm141 connected, and the mtu301 Body- pack Transmitter on, speak into the microphone and verify audio operation. Set the input levels on your connected equipment as needed. You are now set to use the system.

9.Turn the transmitter off when not in use. Remove the batteries if the transmitter is not to be used for a long period of time.
