The MP 2500 R as D/A Converter
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.
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
the button or the button (for the USB DAC IN) on the FM1000
(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.
During D/A converter operations the MP 2500 R integral screen displays the
characteristics of the digital input signal.
