XLR Desk Stand Transmitter Installation & Operation

Thank you for purchasing the mtu201 XLR Desk Stand Transmitter, a component of Audio-Technica’s SpectraPulse® Ultra Wideband Wireless Microphone System. Please follow the information contained in this manual closely, and refer to the SpectraPulse® Owners Manual for system operating instructions.

The mtu201 XLR Desk Stand Transmitter is optimized to work with Audio-Technica Engineered Sound® gooseneck microphones with 3-pin XLRM-type output. The unit provides phantom power to the microphone and features a programmable touch-sensitive switch (for push-to-talk, push-to-mute, or toggle operation) and 9-hour rechargeable battery life. It also offers an on/off switch and LEDs indicating power/mute and link status as well as low-battery warning. Each mtu201 operates using 2 AA batteries. Standard alkaline or NiMH rechargeable batteries can be used. Charging contacts on the base of the mtu201 allow it to be dropped into the Audio-Technica cei007 Charging/Encryption Interface; see SpectraPulse® Owners Manual for instructions.

1.Insert 2 fully charged rechargeable NiMH AA batteries or 2 fresh AA 1.5V batteries in each mtu201 XLR Desk Stand Transmitter. (See Battery Selection & Battery Installation, page 6). Note: Be certain the NiMH batteries are fully charged: see SpectraPulse®

Owners Manual.

2.Select a unique channel address on the bottom of each mtu201 XLR Desk Stand 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 an Engineered Sound® gooseneck microphone with 3-pin XLRM-type output to the XLRF-type input on the mtu201 XLR Desk Stand Transmitter.

4.Turn on the power switch on the bottom of each mtu201. The Power LED on the top of the base will glow blue. (See Power On/Power Off, page 6.)

5.Confirm link status. If the mtu201 XLR Desk Stand Transmitter is properly linked, the Link LED will glow blue and the top green light on the corresponding aci707 channel will light.

(See SpectraPulse® Owners Manual.)

6.Confirm mute/live audio status. When the audio is on, the elliptical Live Audio LEDs glow blue. To change mute status, depress the desk stand transmitter’s soft-touch switch. (See Audio/Mute LED, page 7 ). (Note: Switch function is programmable. See SpectraPulse® Owners Manual.)

7.Confirm battery status. Low battery is indicated by blinking power light (at the top of the desk stand transmitter). (See Low Battery Warning, page 7.)

8.With the aci707 on and connected as desired, the drm141 connected, and the XLR desk stand transmitter on, speak into each microphone and verify audio operation. Set the input levels on your connected equipment as needed. (If connected equipment requires line-level inputs, set DIP Switch #6 to line level as described in DIP Switch 6 selects Line or Mic level in SpectraPulse® Owners Manual). You are now set to use the system.

Note: For SpectraPulse® system operation, see SpectraPulse® Owners Manual.
