Dakota Audio MA-4 arrays are factory adjustable for both mounting height and pattern
width. The frequency response is tailored for voice or incidental music.(See attached graph).
The Dakota Audio Mini-Array series is stocked in the following lengths: 18”/457mm,
22”/558mm, 23”/584mm, 25”/635mm, 30”/762mm, 36”/914mm, 38”/965mm. Providing good sound control in a small package, the Mini-Array provides one-dimensional sound
control. The pattern control is good side-to-side, while the vertical pattern is very wide.
This gives good sonic isolation between
displays while providing good coverage of
the listeners regardless of their height.
Due to size limitations, the amplifier box is
remote from the speaker array, connected
by a multi-conductor cable (supplied).
Audio input is line level, transformer isolated. The array accepts any standard line
level input, either balanced or unbalanced.
A volume control accommodates a wide range of audio input levels. For installations where
the audio level is set remotely, a switch disables the volume control.
The arrays are powered by a supplied plug-in 15VDC power supply.
The units are constructed of 18 gauge steel with a reinforced fabric grill. The finish is generally black non-reflective powder coating. Other finishes and colors are available by special
order.
In typical applications, the Mini-arrays are mounted horizontally directly above or below a
video or touch screen. Other applications include kiosks, museums, digital signage, P.O.P.
displays, trade shows, or any other application that requires one-dimensional sound control
in a small package.
