main features, qualitative details and technical specification of portable high definition audio recorder
Recording
- Portable high-definition stereo recorder, ideal for electronic news gathering and other high-quality recording tasks in the field.
- CompactFlash, Microdrive.
- Comprehensive system and transport control from the front panel or a PS/2 keyboard.
- Stereo recordings from 44.1kHz to 192kHz, at 16- or 24-bit, to affordable Compact Flash media.
- Uncompressed, time-stamped Broadcast Wave file format.
- Pre-Record Cache that permanently stores the last 5 or 10 seconds (selectable) when in Record Ready to even capture audio events happening before actually starting the recording (can be disabled).
- Retake function that allows user to re-do last recording with a single button press.
- Audio files continually re-saved to safeguard against data loss.
- Complete panel interface or PS/2 keyboard.
Inputs and Outputs
- Balanced XLR mic inputs with phantom power, 20-dB PAD, and analogue peak limiter against unpredictable incoming distortion.
- Low-cut filter on each analogue input that reduces low-frequency noise (impact, rumble, hum, wind etc.)
- Unbalanced stereo line input (RCA). It records directly from any stereo line level source (mixer etc.)
- Unbalanced stereo line output (RCA). It uses HD-P2 as playback source; transfers your recordings to analogue equipment.
- SPDIF digital input and output (coaxial). It records from digital sources, transfer your recordings digitally to any mixer, recorder etc.
- Headphone output (6.3 mm stereo jack).
- Built-in mono microphone and speaker
- FireWire port for connection with computer. Easy and fast file transfer to PC.
- Analogue level controls that allows easy operation without the need to look at the unit.
Synchronization
- SMPTE/LTC timecode input on locking XLR balanced jack.
- Chase locks to incoming SMPTE timecode.
- Video clock input.
- Tri-level sync support for HDTV applications.
- Includes Frame Lock, Lock and Release and flexible Freewheel settings for unpredictable timecode sources.
- Pull-up and Pull-down sample rates included for video format compatibility.
Convenience
- Familiar tape machine-style layout and function.
- Easily enter/edit file names via Computer Keyboard.
- Large, angled, uncluttered LC display for table-top or shoulder strap use.
- Shortcut keys and LED indicators for frequently-accessed functions.
- Recessed Compact Flash slot.
- Runs on eight AA batteries (Alkaline, NiMH or NiCd) or DC power adapter. Battery power is approximately 5.5 hours of operating time.
- Durable and lightweight housing for field use.
- Supplied accessories: Shoulder Belt, Carrying Case, AC adapter CS-P2.
