Controls and Functions
The aci707 Audio Control Interface operates via the safety-approved IEC power cord supplied
for connection to 110/120V AC 50/60Hz power. You must change to an approved power
cord for operation in non-U.S. locations (in which case, the aci707 will operate properly from
100/240V AC 50/60Hz for worldwide use).
7 balanced outputs (3-pin Phoenix-type connectors) are located on the rear panel. For each audio
channel (corresponding to the number of microphone transmitters used), connect a cable to the
corresponding output on the rear of the aci707. Up to seven channels of audio output may be
connected to your external equipment (mixer, recording device, teleconferencing equipment)
from each aci707 unit.
Pin 1 of the Phoenix-type connector connects to ground (shield); Pin 2 connects to audio -, and
Pin 3 connects to audio +. The dual labels (1-7 and 8-14) correspond to the position of the
channel selection DIP switch 4.
Connect a shielded Cat 5 cable to the Link-In RJ45 input connector on the rear of the aci707.
The other end of this Cat 5 cable connects to the drm141 Digital Receiver Module.
Note: Make
certain aci707 power is off before connecting or disconnecting the cable. Note: This is not
an Ethernet connection, do not plug cable from the aci707 into an Ethernet port.
To link two aci707 units together, connect the provided 8" shielded Cat 5 cable from the Link-
Out RJ45 connector on 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.
Provides control interface
from
external equipment. The eight-pin Phoenix-type connector
provides connection points for ground and seven microphones. Dual labels (1-7 and 8-14)
correspond to the position of the channel selection DIP switch 4.
Note: In Local mode, if you apply a closure to the input it will mute the microphone
regardless of the state of the soft-touch button on the microphone/transmitter unit.
Provides logic interface
to
external equipment. The eight-pin Phoenix-type connector provides
connection points for ground and seven microphones. Dual labels (1-7 and 8-14) correspond to
the position of the channel selection DIP switch 4.
The contact closure operation follows the configuration of the soft-touch button on the
microphone/transmitter unit, as follows:
• When switches 1 and 2 are in toggle mode, the closure will activate when the button toggles.
• When switches 1 and 2 are in push-to-mute mode, the closure activates and remains active
as long as the button is pushed.
• When switches 1 and 2 are in push-to-talk mode, the closure is deactivated while the
button is pushed.
• When switches 1 and 2 are in switch disable mode, the button is inactive.
