Marantz CDR310 User Manual

Professional Portable CD Recorder

CDR310

Marantz is taking CD recording to the next level with the CDR310, the
first truly portable, affordable CD-based field recorder. Whether for
documentation, duplication, or archiving, audio CDs promote confidence
through their permanence and universality. While digital recording and CD
burning have been commonplace for several years, existing hardware has
lacked the go-anywhere flexibility and ease of use that users have come to
expect in the digital age. The CDR310 has changed all that.

The CDR310 frees the user from the constraints of system-based
solutions, delivering the same great recording quality in portable field
capture as it does in permanent installations. With an on-board hard
drive, the compact, lightweight CDR310 records high quality 16-bit audio
in CD-DA, WAV, AIFF or MP3 file formats, then can burn a CD instantly,
on location. Best of all, the CDR310 has battery operation capability so
you can take it anywhere

In addition to the ease of one-touch recording, users will quickly come to
appreciate two powerful features of the CDR310 – Background Record

and Adjustable Pre-record modes. Together, these features help ensure
that you won’t miss a thing – even when a meeting or event starts
without warning.

Designed to meet the needs of AV integrators, rental firms, corporate
boardrooms, broadcasters, government agencies, and houses of
worship, the CDR310 provides outstanding features that are easy to
use. When your event is over, just hit the Stop button, and then press
the Make CD button. The CDR310 will politely ask if you’d like to
burn a CD. Just say yes. The CDR310 does the rest, and everyone
goes home happy.

Key Features

• Digital hard disc recording in a variety of formats

• Instant CD burning

• Convenience and portability with one-touch record operation

• Flexible record modes – Pre-Record, Background Record,
Silent Skip, Adjustable Auto Track

• Professional hardware from input to output

Digital Recording

On-board hard drive records in your choice of formats: CD-DA,
uncompressed WAV and AIFF, or MP3. The system records high quality,
16-bit audio at a 44.1 kHz sample rate, and the hard drive holds up to
110 hours of material (MP3 mono). You simply select the file type
before recording, and the CDR310 handles the rest.

Instant CD Burning

At the conclusion of your meeting or event, your audio file can be
burned to CD instantly. At the conclusion of recording, simply press
the Make CD button and the CDR310 will ask if you want to burn to a
CD. Just follow the on-screen prompts, and your disc will be ready in
minutes. For events over 80 minutes long in CD-DA format, the
CDR310 offers CD Split burning, dividing the contents over multiple
discs automatically.

Convenience and Portability

One-touch record operation and an easy-to-read LCD status screen
ensure fault-free recording, even for non-technical operators. Its light­weight design and battery operation capability makes the CDR310

equally at home inside an office or out in the field. When there’s no
wall outlet around, the unit accepts AA alkaline batteries, or optional
Ni-Cd and Ni-MH rechargeables. Using the optional RB1651 battery,
the CDR310 delivers up to 4 hours of continuous operation.

Multi-mode Recording Features

The CDR310 incorporates Pre-Record mode along with Background
Record to capture all the action. By simply powering up, the Pre-Record
mode is engaged. This creates a rolling buffer of recorded audio, up to
10 seconds long (user selectable). So if your meeting or event starts
unexpectedly, you’re protected.

Once the event has begun, the Rec-Pause function activates
Background Record mode. If there’s a break in the action, just hit
Pause. If anything vital happens, it’s captured on the CDR310’s hard
drive. When the meeting officially resumes and you release the Pause
control, the CDR310 gives you the option of deciding whether to keep
the audio captured during Background Record.

Another easy-to-use option is Silent Skip recording. This function uses
voice activation to save disc space by automatically pausing during
quiet passages, creating a tighter, more client-friendly recording.

Professional Hardware

Analog line level and balanced high perfomance XLR microphone
inputs are included, as well as S/PDIF-format digital I/O with high
quality A-D converters. The CDR310 also provides +48V phantom
power, and even has an integrated condenser microphone and playback
speaker right on board. Remote control is also available by using the
optional RC600PMD.
