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.)
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.

Channel address selection is via a rotary switch on the bottom of each desk stand
transmitter. The switch is numbered for channel addresses 1 through 14; these channel
addresses correspond to the audio outputs on the aci707 unit. Use the provided screwdriver
to select a different channel address for each desk stand transmitter (you cannot have two
microphones on the same channel address). The Audio Control Interface (aci707) comes
from the factory set for channel addresses 1 through 7. If you wish to use it for channel
addresses 8 through 14, change the DIP switch on the back panel of the aci707 as described
in the SpectraPulse® Owners Manual.
