• When a digital sound signal that has a sampling frequency that is not
supported by this unit is input, the input indicator (COAXIAL or OPTICAL)
flashes in the display.
NOTE
• Do not input non-PCM signals, such as Dolby Digital, and DTS. This causes noise
and could damage the speakers.
• If the sampling frequency switches, such as from A mode to B mode in a CS
broadcast, muting may operate for 1 – 2 seconds, cutting the sound.
Explanation terms
P
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
If a malfunction occurs in this unit, the power indicator blinks red and the
unit switches to standby mode.
S
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to
the original.
Source direct
Playback with higher fidelity to the source becomes possible, as input
audio signals are output by bypassing the audio quality-control circuits
(BASS/TREBLE/BALANCE).
Speaker impedance
This is an AC resistance value, indicated in Ω (ohms). Greater power can
be obtained when this value is smaller.
