The Bogen Gold Seal Series amplifiers were designed with the sound contractor in mind. They provide unparalleled flexibility and versatility, without the need for add-on modules.

Unlike other typical amplifier lines, the professional sound contractor need not purchase a higher-powered amplifier just to get more extensive features or flexibility. Each of the Gold Seal Series amplifier models incorporate the exact same set of features – from 35 watts up to 500 watt models.

In addition to its extensive input flexibility, the Gold Seal D-Series amplifiers offer a combination of features not found in any other commercial amplifier.
