Overview

ENTASYS 750 Watt External Autoformer White

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 I2R 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.

The input wires to the transformer are then attached to the barrier strip terminal. Note the proper terminals to which the input wires should be connected to yield the desired maximum drive level to an ENTASYS array comprised of one, two, or three columns. This information is printed on the input label of the transformer and is shown in Figure 18. Once all of the wires are connected to the transformer the Input Panel Cover may be attached to the transformer. This will help protect the input connections from moisture and debris.

Recommended Low Frequency Loudspeakers

The performance goals and design of the ENTASYS loudspeaker systems inherently limits their low frequency extension. When frequency response below 200 Hz is required additional low frequency loudspeakers and/or subwoofers should be used. Community has several high quality, low frequency loudspeaker systems that are recommended for use with ENTASYS. These include the Versatile Low Frequency (VLF) Series, VERIS subwoofers, and the iLF218.

The VERIS subwoofers are ideal mates for ENTASYS. The VERIS 210S, dual 10-inch, or 212S, dual
12-inch, can provide low frequency extension to approximately 45 Hz.

The Versatile Low Frequency (VLF) Series loudspeakers will also work well with ENTASYS when space considerations restrict the size of the loudspeaker enclosures. The dual 8-inch VLF208 can extend system response to 60 Hz while the dual 12-inch VLF 212 can extend system response to 43 Hz, albeit at slightly lower maximum output levels.
