REC-PRO

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.
