With the new BM Ice 502 pre-amp, B&M extends its new class of B&M home devices. These offer a universal connection to all source units of your high-end system, whether analogue or digital.  Both high quality analogue sources as well as new digital media with the highest resolution are accepted by the BM Ice 502 and converted into the correct format.  Puristically simple to operate with an IR remote control; analogue signals are converted to the digital plane and then connected without loss to our speakers.  By the same token it is possible to connect music files from a media server via a USB input and feed the speakers or an analogue power amplifier.  At the same time, the high precision internal clock continuously regenerates the tact information of all signals being processed.  After the internal volume control and processing by a proprietary dithering algorithm, the music signal is made available at the following outputs:

 - an AES-conform digital output for a direct connection to the digital inputs of the B&M loudspeakers
 - an analogue, symmetric output with a performance that pushes the limits of what is physically possible over our HD-DAC, both in XLR format and on the cinch socket.
