aptor when “SOUND MODE” is set to “NORMAL”)
Frequency response
DVD (PCM 96 kHz): 4 Hz to 44 kHz (
±
1 dB)*
DVD (PCM 48 kHz): 4 Hz to 22 kHz (
±
1 dB)*
CD: 4 Hz to 20 kHz (
±
1 dB)*
Signal-to-noise ratio (S/N ratio)
110 dB* (AUDIO OUT jack only)
Harmonic distortion
0.005%
Dynamic range
DVD: 103 dB*

0.001% W PEAK)
Maximum power output (at DC)
25 mW + 25 mW (16 ohms)
* The signals from AUDIO OUT jack are measured. When you play PCM sound tracks with
a 96 kHz sampling frequency, the output signal from the OPTICAL jack is converted to
48 kHz sampling frequency.
