Lectrosonics SPDR Stereo Portable Digital Recorder.
The second recorder from Lectrosonics, the SPDR (Stereo Portable Digital Recorder) delivers advanced technology and features, including stereo mode with two channels available. As a backup recorder in a bag, the recorder is small, yet packed with features, including extended run time, optional external power and higher sample rates.
On occasion, there is a need to record high quality, stereo audio in circumstances where a traditional full sized recorder is impractical or when a reliable backup is needed. When talent is at an extreme distance or using a wireless microphone is not practical (knights in armor come to mind), the SPDR can travel with your subject and record professional quality stereo audio, synchronized with timecode.
The SPDR can be tethered to a camera to capture a higher quality or backup audio recording. The headphone output doubles as a line output to feed the AV input on a camera.
Setup and adjustment is made through an intuitive interface provided by the keypad and LCD. The housing is an aluminum extrusion with machined aluminum top and control panels, as well as a hard anodized finish.
Broadcast Wave Format
With a timecode jam at the start of the production, the audio data file contents include a timing reference to make it easy to synchronize them in the time line. The industry standard BWF/.WAV file format is compatible with essentially any audio or video editing software.
iXML HEADER SUPPORT
Recordings contain industry standard iXML chunks in the file headers, with the most commonly used fields
Standard TA5 mic/line inputs
The input connectors are the industry standard TA5M jacks that accept analog mic or line level signal. If using mic inputs, the SPDR provides bias voltage to power a wide variety of electret lavaliere microphones. The input connection and wiring is compatible with microphones pre-wired for “compatible” and “servo bias” configurations to feed 5-pin inputs on Lectrosonics wireless
AES3 Digital Input
An optional digital input is available with suggested Lectrosonics MCAES3 used to connect the output to the AES3 digital input of a mixer or recorder; TA5F jack to 3-pin female XLR connector.
Timecode can be copied from the internal real time clock, for projects where it is desirable for timecode to approximately match time of day but it is not necessary to keep time with other devices. Timecode defaults to zero at power up if no timecode source is used to jam the unit. A timing reference is logged into the BWF metadata.
Dual Sample Rates
The SPDR has two sample rate options available;
48 kHz is an industry standard rate and should be suitable for nearly all purposes. At 96 kHz, the microSDHC memory card will be used up twice as fast, but will have slightly less phase distortion near the top end of the audible spectrum (close to 20 kHz).
Linked vs. Independent Stereo
The Linked Stereo option operates limiters on both channels together to preserve the balance of the stereo image. Use Independent Stereo when you have two separate sounds/voices and each input will have a separate limiter.
Split Gain Mode
There are two recording modes available in the menu, HD Mono, which records a single audio track and Split Gain, which records two different tracks, one at the normal level and another at -18 dB as a “safety” track that can be used in place of the normal track in the event
that overload distortion (clipping) has occurred on the normal track. In either mode, recordings over 4GB are broken into sequential segments so very long recordings (over approx 5 hours in HD mode or 2.5 hours in split mode) will not be a single file.
Dual Power Sources
The SPDR has an external power input with internal battery switch over, allowing all day recording from your bag battery with immediate fall back to the internal batteries should there be an external power loss.
