Modifications: B8-300h, B8-600h, B8-1200h, B8-2400 (the last digits in the model's name show the maximum recording duration in hours – sampling rate 8 k Hz, 2 bit ADPCM).
B8 model is produced in a plastic case. Dimensions: 59x28x9 mm, weight: 20g. Battery: CR2450.
Continuous operation duration:
- in record mode: up to 250 hours;
- in playback mode: up to 50 hours;
- in standby mode: 2 years;
- in VAS mode: 2500 hours.
Technical parameters:
- Recording time in ExtraLongPlay mode (modified 2-bit ADPCM, sample rate 8 kHz, 16 Kb\s) 300-2400 hours (flash memory 2-12 GB);
- Supply voltage: 2,7... 3,2V
- Operation temperature: -20 ... +50 °C
- Maximal audio band:
- At play back from PC: 100 ... 6000 Hz
- At play back via earphone: 100 ... 3800 Hz
- Audio sample rate: 16000, 8000, 4000 Hz
- Codec resolution: 16 digits (using external microphone the dynamic range is 18 digits)
- Sample rate: -72 dB
- Quality, format and data recording density:
- Without compression (linear), sample rate is 16 kHz, 256 Kbit/s, k=16
- Without compression (linear), sample rate is 8 kHz, 128 Kbit/s, k=8
- Without compression (linear), sample rate is 4 kHz, 64 Kbit/s, k=4
- Logarithmic compression, sample rate is 16 kHz, 128 Kbit/s, k=8
- Logarithmic compression, sample rate is 8 kHz, 64 Kbit/s, k=4
- Logarithmic compression, sample rate is 4 kHz, 32 Kbit/s, k=2
- Modified 4-bit ADPCM, sample rate is 8 kHz, 32 Kbit/s, k=2
- Modified 2-bit ADPCM, sample rate is 8 kHz, 16 Kbit/s, k=1
- Modified 4-bit ADPCM, sample rate is 4 kHz, 16 Kbit/s, k=1
- Modified 2-bit ADPCM, sample rate is 4 kHz, 8 Kbit/s, k=0.5
where k is the coefficient, showing how many times the maximum record time decreases at record quality increase.
- Data transfer rate via USB-interface: up to 1,5 Mb\s
- Current consumption:
- Stand-by mode (with LCD on): 0,14 mA
- Stand-by mode (with LCD off): 0,014 mA
- Record mode (depending on the recording profile): 1,5 mA - 3,6 mA
- VAS mode, audio level is lower than the threshold value: less than 0.2 mA
- Built-in microphone sensitivity 7-9 m
