USER INFORMATION.

INTRODUCTION

Thank you for purchasing the Audio-Technica SpectraPulse wireless microphone system. It is our hope
that the system will bring you years of trouble free pleasure and performance. Please follow the
information contained in this manual closely as it will assist you in using your equipment effectively.

PART 1. REGULATORY REQUIREMENTS.

“This equipment may only be operated indoors. Operation outdoors is in violation of 47 U.S.C. 301
and could subject the operator to serious legal penalties.”

“This device complies with Part 15 of the FCC rules. Operation is subject to the condition that this
device does not cause harmful interference”

“This device complies with INDUSTRY CANADA R.S.S. 210, en confomite avec IC: RSS­210/CNR210.
Operation is subject to the following conditions: (1) This device may not cause harmful interference
and
(2) This device must accept any interference received, including interference which may cause

undesired operation.”

“Note: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the F CC Ru le s. Th ese limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at own expense.”

Please note that your SpectraPulse system operates in a frequency band in a way which may make its
use subject to certain FCC and other regulatory agency restrictions and licensing requirements. No
changes or modifications may be made to this equipment except by the expressl y approved responsible
party for compliance. Changes or modifications could void the user’s authority to operate the
equipment, and will also void Audio-Technica warranty coverage. For further information, Please
contact your local office of the FCC as applicable.

CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to
qualified service
personnel. No user-serviceable parts inside . Do not expose to rain or moisture.

The circuits inside the receiver and transmitt er hav e be en pre cisely adjusted for optimum
performance and compliance with feder al re gu la tions. Do not attempt to open the receiver or
transmitter. To do so will void the warranty, and may cause improper operation.

Notice to individuals with implanted cardiac pacemakers or AICD devices:

Any source of RF (radio frequency) energy ma y interfere with normal functioning o f t he
implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts
output) which are unlikely to cause difficulty, especially if they are at least a few inches away.
However, since a “body-pack” mic transmitter typically is placed against the body, we suggest
attaching it at the belt, rather t h an i n a shirt pocket where it may be immediately a dja cen t to
the medical device. Note also that any medical-device disruption will cease when the RF
transmitting source is turned off. Pl ea se con tact your physician or medical-device provider if

you have any questions, or experience any problems with the use of this or any other RF
equipment.
.

CAUTION! The circuits inside the receive r an d transmitter have been precisely adju sted for
optimum performance and compliance with federal regulations. Do not attempt to open the
receiver or transmitter. To do so will void the warranty, and may cause improper operation.

PART 2. USING THE ACI707 AUDIO CONTROL INTERFACE

The ACI707 Audio Control Interface operates via the safety-approved IEC power cord supplied for
connection to 110-120V/50-60Hz AC power. You must change to an approved power cord for
operation in non-U.S. locations. In this case, the ACI707 will operate properly from 100V-240V,
50/60Hz for worldwide use. Plug the ACI707 into the AC power source, but do not turn the power on
yet.

Connect a shielded CAT5 cable to the “Link In” RJ45 input connector on the rear of the ACI707.
CAUTION – do not plug an Ethernet cable into this connector.

Locate the section labeled “Audio Outputs” located at the bottom left portion on the rear of the ACI707.
For each audio channel (corresponding to the number of boundary microphone transmitters used),
connect a cable to the corresponding output on the rear of the ACI707. Up to 7 channels of audio
output may be connected to your mixer or PA system from each ACI707.

Depending upon the audio electronics input for your system , you may select the output level of the
ACI707 to be either “Line” or “Mic” level. Locate the switch on the rear of the ACI707 (near the
Audio Outputs) and set up or down as shown in the picture/label for correct output level. A light will
illuminate on the front panel of the ACI707 to indicate whether the unit is operating with Line or Mic
level output.

Two ACI707 Audio Control Interfaces may be linked together in order to accomplish a full 14
channels of audio output from the system. When linking two systems, change the switch on the rear of
the ACI707 to indicate whether it should be outputting channels 1-7 or channel s 8-14.

Locate the “Link Out” RJ45 connector and connect a shielded CAT5 cable from the channels 1-7
ACI707 to the “Link In” RJ45 connector on the ACI707 intended for channels 8-14. Again, remember
this is not for Ethernet connection.

The ACI707 Audio Control Interface is supplied with switches on the rear which can be changed in
order to select the function of the soft-touch button on the MTU101 wireless boundary microphone.
The switches are located in the upper left corner on the rear of the ACI707. You may set the switches
so that the soft-touch button on the MTU101 microphone will either: toggle audio on/audio off; push to
talk (push for audio on); push to mute (audio on unless button pushed – sometimes called “cough
switch”); and switch disable (the soft-touch button does nothing).

If you will be sending closure information for control purposes (such as directing a camera to a specific
channel when it is in use) connect the closure outputs as labeled on the rear of the ACI707.

Closure Inputs will allow control of mute via remote operating equipment. Use the closure inputs as
labeled on the rear of the ACI707.

If you are using the separately-available encrypti on feature, please refer to the owner’s manual for that
product. Encryption for the ACI707 is programmed via an RS-232 connector (DB9) found on the front
panel of the ACI707. When the unit is encrypted, the “Encryption Enable” light will be illuminated on
the front panel.
