Recording and playback time Maximum 74 minutes (MDW-74, stereo recording) Maximum 148 minutes (MDW-74, monaural recording) Revolutions 400 rpm to 900 rpm (CLV) Error correction Advanced Cross Interleave Reed Solomon Code (ACIRC) Sampling frequency 44.1 kHz Sampling rate converter Input: 32 kHz / 44.1 kHz / 48 kHz Coding Adaptive TRansform Acoustic Coding (ATRAC) Modulation system EFM (Eight to Fourteen Modulation) Number of channels 2 stereo channels 1 monaural channel Frequency response 20 to 20,000 Hz ± 3 dB Wow and Flutter Below measurable limit Inputs Microphone: stereo mini-jack, 0.22-0.78 mV Line in: stereo mini-jack, 69-194 mV Optical (Digital) in: optical (digital) mini-jack Outputs Headphones: stereo mini-jack, maximum output level 5 mW+ 5 mW, load impedance 16 ohm Line out: stereo mini-jack, 194 mV, load impedance 10 kilohm General Power requirements Sony AC Power Adaptor (supplied) connected at the DC IN 3V jack: 120 V AC, 60 Hz (US model) 220-240 V AC, 50/60 Hz (Hong Kong model) 100-240 V AC, 50/60 Hz (Tourist model) Nickel metal hydride rechargeable battery NH-14WM (supplied) Two LR6 (size AA) alkaline batteries (not supplied) ­ Continued on next page ­ PORTABLE MINIDISC RECORDER MICROFILM ­1­ Battery operation time Batteries NH-14WM nickel metal hydride rechargeable battery Two LR6 (SG) Sony alkaline dry batteries NH-14WM + Two LR6 (SG) Precautions for Laser Diode Emission Check Recording Approx. 2.5 hours Approx. 5 hours Approx. 9.5 hours Playback Approx. 4 hours Approx. 10 hours Approx. 16 hours When checking the emission of the laser diode during adjustments, never view directly downwards as this may lead to blindness. Precautions for Using Optical Pick-up (KMS-280A) As the laser diode inside the optical pick-up damages by static electricity easily, solder the laser tap of the Optical pick-up flexible board when handling. Also take the necessary measures to prevent damages by static electricity. Handle the Optical pickup flexible board with care as it breaks easily.
