OVERVIEW The Glensound Signature Series ADA2:6G is a professional audio distribution amplifier. It is manufactured using high quality components and low noise audio circuits to provide many years of trouble free use. Although traditionally a broadcast manufacturer, Glensound’s products are equally at home in professional and high end home studios, industrial installations and live pro sound environments. The ADA2:6G can therefore be used in a number of applications.

They can also be mounted underneath desks or work tops and can be either permananetly mounted or stood (using the supplied feet) on top of desks or worktops.
