ENTASYS 750 Watt Autoformer: ENT-750T, ENT-750TW
The ENTASYS 750-watt autoformer is a step down auto-transformer for use in constant voltage
distribution systems. Designated the ENT-750T , it can be used to minimize the I
2
R losses of long cable runs by
converting the distributed high voltage, low current signal to a lower voltage, higher current signal that can
effectively drive the ENTASYS loudspeaker systems.
Included with and shipped attached to the 750W Autoformer is a mounting bracket (“T”-bracket). This is
similar to, but shorter than, the mounting bracket supplied with ENTASYS loudspeakers. This bracket may be
used to mount the transformer directly to a wall as shown in
Figure 15 . This is the only way to mount the
transformer if it is to be placed below an ENTASYS array. The transformer may be electrically connected to the
ENTASYS array using the barrier strip terminals on the top of the transformer. When this mounting is used the
included Rubber Plug should be inserted into the bottom dual banana jack recess area to seal it from moisture
(
Figure 16 ).
The transformer may be mechanically attached to the top of an array using the Joiner Bar and the
associated hardware that is included with the transformer. This attachment method is shown in Figure 17 .
Mounting the transformer in this manner allows the output of the transformer to be routed to the input of the
ENTASYS array via the dual banana jumper plug, also included with the transformer.
