Usb B Digital Input - AVM EVOLUTION CD 3.2 Operating Instructions Manual

The digital filter settings SMOOTH and STEEP can be set according to your personal preference.
Technically speaking, the setting STEEP indicates a steep filter characteristic at the upper end of the
frequency band, leading both to a flat amplitude frequency response and a rather strong phase
rotation. SMOOTH however leads to a less steep filter characteristic by showing a slightly earlier
attenuation of the amplitude frequency response with almost no phase rotation.
Please note that a chosen filter setting is only true for a selected input and is being recalled every time
you select the respective input again, even when the device has completey been switched off before.

2.7 USB B Digital Input

If a digital signal from a computer (PC or Mac) is connected to the USB B digital input of your CD
player, you can choose between two different modes (LO RES or HI RES) by pressing the PROG
button (4).
LO RES can be used to play back a digital input signal with a sample rate of up to 48kHz without the
need for an additional audio driver on your Windows PC or Macintosh Computer.
HI RES can be used to play back a digital input signal with a sample rate of up to 192kHz without to
install an audio driver on your Macintosh Computer. If you are using a Windows PC you will need to
install an additional driver which is available for download on the respective product page at
www.avm-audio.com.
Below the LO RES and HI RES display, the currently active data format is displayed (PCM or DSD).
Please note that you need to select the HI RES mode in order to play back a DSD64 file.
