Please note that only the settings NAT / STEEP or NAT / SMOOTH are available if USB is

selected.

The digital filter settings SMOOTH and STEEP can be set according to your personal

preference. Technically speaking, the setting SHARP 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 after the device has completey been

switched off.

2.8 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 (22), 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 96kHz

without the need for an additional audio driver on your Windows PC or Mac.

HI RES can be used to play back a digital input signal with a sample rate of up to 384kHz/24

Bit (PCM) without the need to install an audio driver on your Mac. 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.

Below the LO RES and HI RES indication, the currently active data format is shown on the

display (PCM or DSD).

Please note that you need to select the HI RES mode in order to play back DSD64 or

DSD128 files.
