MA-4 and MA-5 Amplifier
MA-4's may also be ordered in custom lengths to fit the application in quantities of 100 or more. 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.
To further reduce the visible element of the MA-4, the amplifier (0.9 inches / 22 mm x 5 inches / 127 mm x 3.25 inches / 82mm) 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. MA-4's have a single mounting hole at each end that is 3/16 of an inch wide and is 3/8 of an inch from the side (centered between the top and bottom of the speaker array)
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.
