The EZ-HDA6 contains six stereo headphone amplifiers with individual front-panel volume controls. Headphone outputs are provided on rear-panel 1/4" jacks. One input signal feeds all the amplifiers. Stereo RCA jacks, a MINI jack and a dual 1/4" jack (for "loop out" connection) are provided for connecting the input source. The EZ-HDA6 is used in music stores, houses of worship, studios, museums, home component systems and commercial sound systems.
