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.

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)

Coding:

ATRAC (Adaptive Transform Acoustic Coding),
