Operating instructions

1.5 Phono (option)
The phono pcb is also installed in a slot in the rear panel of the unit. You can connect MC pickups as well as
MM-types. The phono pcb is very versatile and allows individual setting of cartridge type, cartridge load and
gain. The RIAA-equalization uses precise film capacitors and has a built in subsonic filter. So it works well
with most of all cartridges on the market.
1.6 D/A-converter (option)
The optional D/A-converter can also be plugged into a slot from the rear panel. It offers 3 digital inputs: The
optical and the coaxial input accept digital signals from CD-players, digital tuners and other sources. The
USB input can be connected to a suitable Computer. PCs working with WINDOWS XP or higher as well as
most Apple computers recognize the USB input automatically soon after connection. There is normally no
need to install special driver software.
The converter uses upsampling technique (192 kHz/24 bits). The jitter coming from the digital input signal is
nearly completely eliminated. Upsampling to 192 kHz also spreads the inevitable quantization noise to a
broader frequency range and therefore reduces (compared with CD format) the part of quantization noise in
the audible frequency range by a factor of over 4.
The D/A conversion is done by a highly precise IC which works with 24 bits accuracy. The reconstructed
music signal offers therefore crystal clear original sound with no loss of fine details.
