Notes on use

USB INPUT:

The DSD-SR MK2 is equipped with an XMOS based USB chipset that does not require a driver for Mac or Linux OS.

However, a driver is required for Windows. Please contact us in order to obtain the Windows driver:

info@aplhi .com

After you have received the Windows driver from us, please connect the DSD-SR MK2 to the computer via USB cable

and then initiate the driver installation. Please note that, if the DSD-SR MK2 is not powered On and connected to

the computer with USB cable, the driver will not install properly.

When connecting the DSD-SR MK2 to Linux based external audio renderers, please make sure that the DAC is

powered On rst, prior to connecting the USB cable to the audio renderer.

In other words, please always start the DSD-SR MK2 rst and then the audio renderer. Please note that the

DSD-SR MK2 does not use the +5V power from the USB bus coming from the computer or streamer.

DTR INPUTS:

The DSD-SR MK2 features two proprietary DTR inputs – DTR1 and DTR2. These inputs are intended for connecting

APL Hi-Fi digital sources only, such as the DTR-MR CD/SACD transport and the DNP-SR network streamer.

FRONT DISPLAY:

It is highly recommended to use the display O mode for best sound quality.

This mode is set by pushing the DISPLAY button on the front panel or remote.

The display will show the changes made and then shut O again in approximately 3 seconds.

DIGITAL FILTERS SELECTION:

DSD-SR MK2 digital lters can be selected by pressing the FILTER button on the remote. That button toggles

between Zero (non-oversampling), Slow (slow-rollo ) and Normal (sharp-rollo ). The digital lter selection

is possible only with PCM format. The digital lters do not work for Native DSD playback.

REQUIRED BREAK-IN TIME:

It takes around 200-300 hours of break-in time for the DSD-SR MK2 to fully settle.

Please make sure to run the DSD-SR MK2 in your audio system for a minimum of 3 days,

prior to any critical evaluation.

If you have any questions of concerns, please do not hesitate to contact us - info@aplhi .com
