Press the FILTER button on the front panel or D.FILTER 

button on the remote control unit to select a digital 

fi

 lter 

type FLAT or PULSE. 

Click noise may happen from speakers 

or headphones when changing the digital 

filter. It is recommended to change the 

fi lter after volume down.

Note

:  Digital filter type is always FLAT when DSD 

signal is played, and PULSE is not available.

Note

:  When the display is " off " by dimmer setting 

pressing once the FILTER button will return the 
display brightness to the default " brighter " and 
show the current digital filter type. Press the 
button again to change the digital 

fi

 lter type.

FLAT

 digital Filter is very common in digital audio items. 

The frequency response is almost perfect, but such 

fi

 lter 

cause " ringing " in the time domain. Some energy of a 
pulse signal is distributed in the time domain, before and 
after the pulse centre. Any ringing before the signal does 
not exist in nature.

PULSE

 digital filter avoids the problems in the time 

domain and thus has a very good response in the time 
domain. The frequency response of the PULSE digital 

fi

 lter shows a soft roll-off at high frequencies. This results 

in about -2dB at 20kHz with an input sampling frequency 
of 44.1kHz. For higher sampling frequencies the roll-off is 
irrelevant and the " PULSE " 

fi

 lter is the best choice. For 

44.1kHz and 48kHz the better result may depend on the 
whole system as well as personal preferences.

Display brightness 

can be changed in 

different three levels. 

Press the DIMM key 

on the remote control 
unit to dim the display. 
The display brightness 
will toggle through 
" brighter " (default), 
" off " and " lighter ".

During " off " mode

:

  Pressing once a function button on the front panel or 
remote control unit relating to the input, digital filter or 
volume the display will return to " brighter " and show the 
current setting. Press the function button successively to 
change the setting. 5 seconds later the display brightness 
will return to " off " automatically.

 Regardless of any DIMMER setting the brightness will 
return to the default whenever the power is turned on 
again.

 If the surface of the DA5 case becomes soiled, wipe 
with a soft cloth or use diluted neutral cleaning liquid. 
Be sure to remove any fluid completely. Do not use 
thinner, benzene, alcohol, chemical cloths or bleaching 
agents as these may damage the surface of the CD5 
case. Also avoid using aerosol insecticides near this 
appliance.

  DA5 requires no periodic maintenance, and contains 
no user-serviceable parts. Contact your dealer or an 
authorized CEC service center for an inspection and 
repair in case of malfunction.
