Power source:
DC 5V: AC adaptor (AC 230 - 240V, 50/60 Hz)
DC 1.5V: Commercially available, “AA” size (LR6), al-
kaline battery x 1
DC 1.2V: Optional rechargeable Nickel-Metal Hydride
battery (AD-N70BT) x 1
DC 4.5V: Optional car adaptor, AD-CA20X
(for cars with a 12-24V DC negative earth elec-
trical system)
Power consumption: 7 W (AC adaptor)
Output
RMS; 20 mW (10 mW + 10 mW)
power: (0.2% T.H.D.)
Charging Approx. 3.5 hours (90 %)
time: Approx. 5.5 hours (fully charged)
(When using the AC adaptor included with the unit)
Battery life:
● The continuous recording time is for analogue inputs when the
volume level is set to “VOL 0”.
● The continuous play time shows the value when the volume
level is set to “VOL 15”.
● The above values are the standard values when the unit is
charged and used at an ambient temperature of 20
° C (68 ° F).
● The operating time when using an alkaline battery may be dif-
ferent, depending on the type and manufacturer of the battery,
and on the operating temperature.
Dimensions: Width: 99.9 mm (3-15/16”)
Height: 22.9 mm (29/32”)
Depth: 77.9 mm (3-3/32”)
Weight: 168 g (0.37 lbs.) without battery
Input socket: Line/optical digital, microphone
(powered by the main unit)

■ MiniDisc Recorder
Type: Portable MiniDisc recorder
Signal readout: Non-contact, 3-beam semi-conductor laser pick-up
Audio channels: Stereo 2 channels/monaural (long-play mode)
1 channel
Frequency response: 20 – 20,000 Hz ( ± 3 dB)
Rotation speed: Approx. 400 – 900 rpm
Error correction: ACIRC (Advanced Cross Interleave Reed-
Solomon Code)

Recording method: Magnetic modulation overwrite method
Sampling frequency:44.1 kHz (32 kHz and 48 kHz signals
are converted to 44.1 kHz, and then recorded.)
Wow and flutter: Unmeasurable (less than ± 0.001% W. peak )
When using a commercially
available, high capacity, “AA”
size (LR6), alkaline battery
