Halcro Amplifiers DM-8 Preamplifier

The HALCRO dm8 Preamplifier with remote control has set a new standard for preamplification. Bruce Candy has redefined the term "reference" with a revolutionary design. The whole system is now dead quiet, all you can hear is every detail of the music you are playing, no overt tube or transistor characteristics. It of course has the lowest distortion and noise specifications of any preamplifier in the World. For audio connoisseurs there is no better.

SOME OF THE FEATURES ARE: Balance, mute and phase invert all on the front panel, as well as on the remote control,5V DC trigger, to turn Halcro amplifiers on and off in conjunction with the preamplifier,All inputs can be programmed for any source, Power supply and audio section are heavily shielded, RCA voltage & current inputs, XLR voltage inputs, RCA voltage & current output, XLR voltage outputs.

Unit is being sold AS IS, no warranty offered or implied.
