System Installation & Operation
Thank you for purchasing the Audio-Technica SpectraPulse
™
UWB wireless microphone
system.
It is our hope that the system will bring you years of trouble-free performance.
Please follow the information contained in this manual closely, as it will assist you in using
your equipment effectively.
drm141 Digital Receiver Module
The drm141 Digital Receiver Module functions as both the UWB receiver and antenna for 14
channels. It consists of three assembly components that can be used for different mounting
requirements: the main assembly, the front bezel, and the plastic rear housing.
Note: Do not
disassemble the main assembly.
Doing so may void your warranty and possibly void the
authority to operate the unit.
Note: Never plug or unplug the shielded Cat 5 cable to or from the drm141 if the cable is
already connected to the aci707 and the power is on. Make certain aci707 power is off
before connecting or disconnecting the cable.
1. Placement – Locate the drm141 within 300 feet of the aci707. The drm141 Digital Receiver
Module should be mounted to a wall or ceiling or set on a flat surface. Ideal placement is
high, with clear line of sight to all the microphone/transmitter units.
Note: The drm141 must
be in the same room as the microphone/transmitters.
2. To flush-mount the drm141 inside a 3-gang, 2-

" deep electrical box, see
Mounting to a
3-gang electrical box
, page 9.)
3. For more portable or surface applications, the unit is shipped assembled in the plastic rear
housing, which provides key-hole slots on the back for mounting on a wall; or the unit may
be placed on a flat surface. (See
Mounting in the supplied plastic rear housing
, page 9.)
4. Connect the shielded Cat 5 cable (supplied) to the RJ45 connector on the rear of the drm141.
The other end of this Cat 5 cable will be connected to the “Link In” RJ45 connector on the
rear of the aci707 Audio Control Interface (with aci707 power off). (See
Link-Out and Link-In
RJ45 Connectors
on page 11.)
Note: A 25' shielded Cat 5 cable is supplied with the
system; you may supply your own shielded Cat 5 cable for lengths up to 300'. If you
use your own CAT 5 cable, attach the provided ferrite bead to the cable as close to the
drm141 as feasible. Do not plug cable from the aci707 into an Ethernet port.
aci707 Audio Control Interface
The SpectraPulse
™
aci707 Audio Control Interface provides the connection point to the audio
system, and a control platform to set the system functions. It also provides control interface
points (contact closures) for interface to external equipment. These closures can be used to
activate lights, control cameras, etc.
1. Placement – Locate the aci707 Audio Control Interface within 300 feet of the drm141 Digital
Receiver Module.
Note: The aci707 does not have to be in the same room as the drm141.
2. Plug the aci707 Audio Control Interface into the AC power source. (See
Power cord
, page 11.)
Note: Make certain you do not turn on the power until after all the system connections
are made.
3. With the power off, connect the shielded Cat 5 cable exiting the drm141 to the “Link In”
RJ45 input connector on the rear of the aci707.
Note: Do not plug RJ45 connector or Cat
5 cable into the aci707 with the power on. Do not plug cable from the aci707 into an
Ethernet port.
(See
Link-Out and Link-In RJ45 Connectors
on page 11.)
If a second aci707 is used, connect the included 8" shielded Cat 5 cable from the Link-Out
on the first aci707 to the Link-In in the second aci707.
