o Place the unit in a stable location near the audio system that you

will use with it.

o DO NOT place anything, not even CDs, CD-Rs, LP records or cas-

sette tapes, on top of the units. Doing so could cause damage.

o The voltage supplied to the unit should match the voltage

printed on the rear panel. If you are in any doubt regarding this

matter, consult an electrician.

o Do not move the unit during use.

o Do not open the body of the unit because this could result in

damage to the circuitry or cause electric shock. If a foreign object

Outdoor antenna

In an area where DAB signals are weak, use an outdoor DAB antenna.

There are two main types of antennas available.

Multi-element

Dipole

For use in marginal signal areas. This type of antenna is omnidirec-

tional and should increase the strength of all DAB stations being

received.

Multi-element antenna

Also for use in marginal or poor signal areas. This type of antenna is

directional and has high gain. This antenna needs to be pointed at

the transmitter you want to listen to.

o It is possible to use a TV or FM antenna with your DAB tuner as

this is normally mounted externally. Although this may give a

stronger signal than a simple internal antenna, it is not tuned

specifically for DAB reception.

You need to change the plug on your TV/FM antenna to an F

type, and it may also be necessary to use a signal booster to

enhance the signal.

OFF

The original input signal is sent directly to the D/A converter

without upconversion.

2Fs

If the input audio signal is less than 2× a standard sampling fre-

quency (32, 44.1 or 48 kHz), it is upconverted 2× and then sent to

the D/A converter.

4Fs

If the input audio signal is less than 4× a standard sampling fre-

quency (32, 44.1 or 48 kHz), it is upconverted 4× and then sent to

the D/A converter.

8Fs

If the input audio signal is less than 8× a standard sampling fre-

quency (32, 44.1 or 48 kHz), it is upconverted 8× and then sent to

the D/A converter.

DSD

side the audio band.

FIR SLOW

An FIR filter with a slow roll-off is used to gently cut signals out-

side the audio band.

SDLY SHARP

A short delay filter with a steep roll-off is used to sharply cut sig-

nals outside the audio band.

SDLY SLOW

A short delay filter with a slow roll-off is used to gently cut signals

outside the audio band.

o When receiving signals at 352.8 kHz or 384 kHz, the digital filter

will be disabled during playback regardless of this setting.
