Gold Seal Series amplifiers are an extraordinary addition to Bogen's line of quality audio amplifiers. Designed with the sound contractor in mind, they provide unparalleled flexibility and versatility, without the need for expensive add-on modules. The GS250D model enhances the Gold Seal line with 250 watts of power in the same 2 rack space package as the other Gold Seal amplifiers.
