FA-501 36" - 915mm Overhead Directional Speaker

Product Literature

The Dakota Audio FA-501 Directional Audio array is the larger version (36 inches square) of the FA-602. The FA-501 directs the audio signal straight down in a circular pattern (as compared to the FA-602's focused audio signal that projects to the side at a fifteen degree angle and has an oval coverage pattern).

The FA-501's full range sound capability is unmatched in the directional audio industry. It is frequently used where sound quality and control are paramount. Many designers and consultants tell us that the FA-501 is their only choice for applications that require full range sound in a directional speaker. Because of this combination of full range sound and directionality it is being used such diverse applicatons as alarms in control rooms,  museums, and digital signage. 

We will be happy to provide technical advice.  We promise that there will not be a hard sell. In fact we discourage about 10% of the people who call us.  Either their expectations are not realistic, or there are reasons that our products will not work for them.

The FA-501 produces a circular sound pattern enabling a variety of mounting postions from horizontally overhead to mounting vertically on a wall or under a grating in the floor. Our customers have installed these units in every configuration possible, please contact us to learn more.

The FA-501 is covered by Dakota Audio's five (5) year warranty. (We even cover lightning and power surge damage).



The FA-501 is easily field adjustable for both mounting height and pattern width.

There are two push buttons and two rows of LEDs on the top side of the array. One sets the mounting height above the floor in one foot increments from 8 to 14 feet.

The other button controls the pattern width in seven steps from tight to a circle appropriately 10 feet in diameter (depending on the mounting height).

There are two line level inputs. The first is an transformer isolated balanced input for professional applications.  There is also a 3.5mm jack that will accept stereo signals and combine them to mono.

 A volume control and two position gain switch controls the built in amplifier which accommodates a wide range of audio input levels.





A three position switch controls a built in equalizer with three preset adjustments to the audio frequency response for the program material.

The music position provides full range sound.

The voice with music position has a slight rise in the high frequency response to enhance voice intelligibility while maintaining good music reproduction.

The voice position reduces low frequencies for maximum voice intelligibility.The array accepts any standard line level input, either balanced or unbalanced.

For installations where the audio level is set remotely, a switch disables the volume control.

The FA-501 focused sound arrays are powered by either 16 to 18 Volts AC or 24 Volts DC. A plug-in 16 VAC transformer is supplied for installations where local 120 power is available. Where the array power and signal cables share the same conduit, we suggest powering them with 24VDC.

Generally, the arrays are suspended by four thin (0.080 inch) aircraft cables with easily adjustable clips (supplied). There are also four threaded inserts on the top.  1/4 - 20 American thread is standard,  6 millimeter metric threaded inserts are available as an option.

The units are constructed of aluminum, with a non-reflective black powder coat finish.

The snap-on fabric grill cover is provided, available in black or white.  Please add a "B" or "W" to end of the product number when ordering (i.e. FA-501B will be shipped with a black cover)
