Arcam Diva P1000 7 x 135 watt power amplifier, black production prototype from former and now defunct US importer, Audiophile Systems LTD. The P1000 is a very flexible amp with the abilities to use balanced or single-ended inputs for each channel, to provide maximum function with a wide variety of loudspeakers (for example you could passively tri-amp two speakers with this using the chained inputs and have a remaining channel for a center speaker), and to match with other amplifier brands through the adjustable gain settings of 26, 29, and 31.5 db for each channel. Here's the link to the owner's manual - http://www.arcam.co.uk/_ugc/file/p1000e_manual.pdf -. A little scratch on top, otherwise in good shape. I have a P1000 box to ship in, please make an offer, I need to sell. Thanks for looking. I WILL SHIP FEDEX GROUND HOME OR BUSINESS DELIVERY.
