The MP 2500 R as D/A Converter
General Information on
D/A Converter Operation The

MP 2500 R can be used as a high-quality D/A converter for other
devices such as computers, streamer, digital radios etc. which are fitted with
poor-quality converters or no converter at all. The
MP 2500 R features two
optical and two electrical S/P-DIF digital inputs on the back panel to allow this
usage.
A USB-DAC input on the back panel permits to use the
MP 2500 R as D/A
converter for computers.

You can connect devices with electrical co-axial or optical light-pipe output to
the digital inputs of the
MP 2500 R . At the optical inputs Digital In 3 and
Digital In 4 the MP 2500 R accepts digital stereo signals conforming to the S/P-
DIF norm, with sampling rates of 32 to 96 kHz. At the electrical co-axial inputs
Digital In 1 and Digital In 2 the range of sampling rates is from 32 to 192 kHz.
At the
USB DAC IN input the MP 2500 R accepts digital PCM-encoded stereo
signals with sampling rates of 44.1 to 384 kHz (32-bit) and DSD data with
sampling rates of DSD64, DSD128, DSD256 and DSD512.
If you wish the
MP 2500 R to convert audio files from a Windows PC
connected to it, you must first install driver software on the computer (see the
chapter entitled
‘USB DAC operation in detail’
). If you are using a computer
running Mac OS X 10.6 or higher no drivers are necessary.
D/A Converter Operation
Selecting a
D/A Converter Source Select the MP 2500 R as listening source on your amplifier.
Choose the digital input to which you have already connected the source
device which is to be played by pressing the source button

on the front
panel or the  button or the  button (for the USB DAC IN) on the
SRC1 (repeatedly if necessary).
As soon as the source device delivers digital music data, the MP 2500 R
automatically adjusts itself to the format and sampling rate of the signal, and
you will hear the music.
