Lectrosonics SPDR Data Sheet

SPDR

Stereo Portable Digital Recorder

TECHNICAL DATA

• Professional quality low noise digital audio
recordings in Broadcast Wave Format (iXML
metadata) with high dynamic range

• Compact size for easy bag, plant mic and
personal use

• Records to a microSDHC memory card

• Wide range input gain adjustment for mic to
line level signals

• AES input for digital signal chains

• Time code jam/sync from external source

• Standard Lectrosonics TA5M input jack

• Lectrosonics “servo bias” input preamp

• Solid machined aluminum construction

• Over 20 hours of operation on dual AA
lithium batteries

The SPDR is Lectrosonics’ response to customer
demand for a small, lightweight dual channel recorder
for use on virtual reality sound captures or as a backup
recorder for bag systems in the field. The SPDR will let
you capture the full stereo audio of an extreme sport par­ticipant, in-car scenes or in situations where a wireless
system cannot be used.

When used in conjunction with a small mixer and the
SRC receiver, the SPDR makes for a lightweight inter­view setup that provides full redundancy - all fitting into a
small fanny pack.

LEMO

TC Input

• Temperature compensating clock accurate to
less than 1ppm at all temperatures

The industry standard 5 Pin LEMO time code input
allows a simple momentary jam. The high accuracy oscil­lator allows free running precision better than 1 ppm for
those long recording days.

Offering the same high definition display as the PDR, the
SPDR keypad has a tactile feedback riser on the record
button for easy eyes-off recording startup. Dweedle tone
commands allow easy start and stop using the PDRRe­mote app.

The SPDR has an external power input with internal bat­tery switchover, allowing all day recording from your bag
battery with immediate fall back to the internal batteries
should there be an external power loss.

A 32GB memory card allows almost 30 hours of record­ing time at the 48kHz sample rate.

A high quality headphone output is provided for playback
and monitoring.

The rugged aluminum housing allows easy access for
the microSDHC memory card (up to 32GB) and DC input
for external power. Recordings are stored in industry
standard BWF file format (.WAV) with iXML metadata, for
compatibility with third party tools such as Wave Agent
(tm). The deep buffer allows use of slower cards with
high reliability.

The SPDR has outstanding battery life (over 20 hours
on AA lithiums) for long term recording capabilities when
using only internal batteries. If external power is being
used and is accidentally interrupted, a switchover to the
internal batteries takes place automatically. The SPDR
is compatible with the LM style transmitter belt clips. The
wire belt clip (P/N 26526) is included and the hinged
style belt clip (P/N BCHINGED) is available as an option.
