Toa AX-1000A, Руководство по эксплуатации

Страница: 21 / 28

To enable the System Mute, Select which channels should mute using the DIP switches on each AX-1000A.
Then connect all mute terminals in parallel. Connect all "left-side" System Mute terminals together and all
"right-side" terminals together. Do not cross.
Example: Here four AX-1000A's are linked. The
mute terminals are connected in parallel,
and a Remote Master Volume control is
connected to the Master unit.
17. Application Ideas
Churches
Most church sound systems have a moderate number of microphones. It is often the case that only one
microphone, perhaps two, are in use at any given time. To complicate matters, many churches have several
services each Sabbath and various classes, meetings and functions during the week. Typically a different person
will set up the sound for each event.
The AX-1000A is valuable in these applications, since it allocates all the system gain to the one microphone in
operation until more than one mic is on; it shuts the others off even though their channel volume controls are set at
operating level; and it refuses to let the mic in operating go into feedback. If two or more microphones are in use
simultaneously, the system gain is shared among them for maximum acoustical output.
Deeper NOM Attenuation inhibits feedback in very reverberant churches.
The AX-1000A performs these gating and mixing functions accurately and unobtrusively.
Conference Rooms
Company meeting room systems, boardroom systems, courtroom systems and sound systems for legislative
bodies are all variations on one basic installation. Multiple microphones with some sort of System Mute are usually
in place. Up to ten AX-1000A's may be combined, with up to 80 inputs. The primary advantage of the AX-1000A in
a conference room system is freedom from feedback when large numbers of open mics must be controlled.
In highly engineered systems the channel logic outputs offer automatic control for many kinds or audio and video
equipment.
