AYRE DX-5DSD - Manual (Page 40)

A switch on the rear panel allows the Digital Audio
Output to be turned off if its use is not required.
Turning the Digital Audio Output “off” when not
using it will result in slightly higher sound quality
through the analog outputs.
Digital Filter
The digital filter of the Ayre DX-5 DSD features two
user-selectable algorithms. A selector switch is
located on the rear panel. One algorithm produces
greater accuracy in the time domain and is labeled
“Listen”. The other algorithm produces greater
accuracy in the frequency domain and is labeled
“Measure”.
Normally the selector switch is set to the “Listen”
position when listening to music. However some
listeners may prefer the additional high-frequency
energy provided by the “Measure” position.
This switch only affects the Analog Audio Outputs,
and not the Digital Audio Output or either of the
HDMI outputs.
USB Audio Input Speed
USB Audio may connect to the computer at two
speeds. The first is known as “Class 1 Audio” and is
supported by all operating systems (e.g., Windows,
Mac OS X, Linux). Class 1 Audio uses the “Full
Speed” mode of USB and is capable of transporting
all sample rates up to 96 kHz. Select Class 1 Audio
by setting the switch to “Rsrv A”.
