360 Systems’ new DigiCart/E Ethernet Audio
recorder builds on a decade of experience gained
delivering DigiCart II recorders to television
broadcasters.  DigiCart/E is more than an
improvement on the digital cart machine
concept – it’s the foundation of the new, high-
performance, Ethernet Audio system for
television broadcasters. DigiCart/E is 100%
compatible with earlier DigiCart recorders, can
play files produced on them, and uses similar
front panel commands. A key feature of the 360
Systems’ Ethernet Audio

network is the link to



and PC-based audio workstations.  Audio

programs produced on DAWs can be easily
accessed for playback on DigiCart/E.

Networked Audio without 
the Computer

No computer and no mouse – just the hands-
on efficiency of real buttons for all operations.
DigiCart/E is designed from the ground up for
broadcast professionals.  It’s fast, straight-
forward, and easy to use.

DigiCart/E Works the Same 
Way as DigiCart II

Everyone who knows how to use DigiCart II
will know how to use DigiCart/E.  It brings
better displays, better screen messages, and new
networking features, with the same familiar buttons.

Complete File Compatibility 
with DigiCart II

All earlier DigiCart files can be played – whether
Dolby AC-2, 16-bit linear, 44.1 or 48K – so
valuable program content and archives can be
carried forward. DigiCart/E can also create new
files for use in DigiCart II, so earlier hardware
investments remain a valid part of any new facility.

Make Digital Transfers to 
the New DigiCart/E 

• The standard 100MB Zip disks for DigiCart II

still move files back  and forth to DigiCart/E.
DigiCart/E’s newer

 750 or 250

MB Zip drive 

also reads 100

MB disks.

• The original D-NET file transfer protocol 

using AES ports has been maintained, making 
it easy to move valuable files into the new 

• AES/EBU ports perform digital machine-to-

machine transfers. DigiCart’s 75-ohm AES 
ports on BNC connectors can transfer files as
far as 1,000 feet. 

New Editing Tools

DigiCart/E provides a faster way to edit audio.
The weighted front-panel jog wheel moves rapidly
back and forth, making it easy to place marks or
set time points. DigiCart/E offers these non-
destructive editing features: 

• Head trims 

• Tail trims 

• Fade-ins 

• Fade-outs 

• Pre-roll times

• Gain change 

Edits can always be undone, and trim points can
be easily changed for a future re-edit of the cut.
DigiCart/E provides clear indications of edit
points and the present location within a cut.

Ethernet Audio Recorder

Advancing an Industry Standard



background image

File Interchange with Digital
Audio Workstations

The new DigiCart/E employs wave files
(.WAV) as a new native format, and supports
broadcast wave (.BWF) extensions. It is
compatible with most popular workstations,
including Pro Tools


.   Using Ethernet as the

file-exchange medium, DAW files can be
exported in .WAV format to the 360 Systems’
Ethernet Audio server, where they are
immediately available from any DigiCart/E

Local Audio Storage Plus
Network Storage

DigiCart/E provides an important extra level
of reliability by storing important audio files
on its own local hard drive, separate from the
file server.  For example, by optionally copying
files to a DigiCart/E, playback is virtually
guaranteed, regardless of the status of the
audio network. Redundancy is a key part of
the system design.  For example, should a file
commonly used by Master Control be lost on
the file server, it could be played from the local
hard drive on Master Control’s DigiCart/E.

New Audio Standards for
Television Production and

24-Bit Audio Quality

DigiCart/E’s 24-bit audio circuit design
approaches 120 dB of dynamic range from
the analog inputs.  Our Bit-for-Bit


design also maintains 24-bit integrity
through AES ports, assuring error-free
reproduction not only of standard PCM
files, but also of Dolby AC-3 or Dolby-E

Sample Rate Compatibility

Although most users will work at a 48 kHz
sample rate, DigiCart/E is equally adept at
44.1, 88.2 and 96k.  The high-quality
sample rate converter can be positioned at
either machine input or output, permitting
conversion of any sample rate to 48K, or any
other rate.  Now 44.1, 88.2, and 96k music
masters received from compact disks or an
audio workstation can be changed to
standard 48K broadcast files.

Word-Length Compatibility

DigiCart/E plays files of any word length – 16,
20, or 24-bit.  In addition to recording new
material at 24-bits, it can also deliver 16-bit
digital audio for compatibility with DAT
machines or earlier DigiCart recorders.

Mixed File Types Allowed

DigiCart/E can store audio in many different
formats, and play them consecutively without
changing machine setup.  Any desired output
format, such as 48K – 16-bit, can be selected,
regardless of how the original file was recorded.

High-Speed Transfers Through
Ethernet Audio

7When it’s time to actually move a file to or
from the server, the Ethernet Audio network
can move files many times faster than real-time. 

Serial and GPI Control

A variety of serial and parallel ports adapt
DigiCart/E to most facilities:

• An RS-422 serial port operates with standard
ES-Bus protocols; it is compatible with most
automation systems, with DigiCart II, and
with our new RC-Series remote controls.  It
also  supports Peripheral Bus “E-Mem"
commands, giving DigiCart/E direct control
by popular video switchers.

• Five optically isolated GPI inputs provide
control of play, stop, record, pause, and loop.
These conform to the DigiCart II connector
for easy upgrades. 

DigiCart/E Uses a Time-Proven
User Interface

DigiCart recorders are hands-on machines.
Its physical buttons, knobs and display make
it a good choice for fast-paced operations,
with direct access to frequently used
functions.  The new DigiCart/E continues an
eleven-year industry operating standard. Most
users will never open the Operations Manual
to make full use of DigiCart/E.

Why should I consider
DigiCart/E over other
networked audio systems?

• More DigiCart recorders are in use in 

television broadcast than any other brand of
hard disk audio recorder. It has an 11-year
track record.

• DigiCart/E is 100% compatible with your 

present investment in recorded audio, disk 
libraries, system wiring, and operating methods.

• DigiCart recorders are one of the most

reliable pieces of broadcast equipment ever 
made. Tens of thousands of people already 
know how to use DigiCart recorders. 

• People like hardware-based solutions. It’s 

faster and easier to use than a PC. 360 
Systems’ audio network makes economic 
sense for small and mid-size stations. It can 
be expanded to almost any size without
sacrificing the original investment. 

• 360 Systems’ audio network is conservative, 

based entirely on proven technology, and 
can be maintained by available network

In what ways is DigiCart/E
compatible with my investment
in earlier DigiCarts? 

• Operating controls are very similar. People

familiar with DigiCart II can immediately 
use DigiCart/E.

•  Files created on DigiCart II can be played 

on DigiCart/E. Your entire library of
recorded audio is directly playable. Transfer
methods include Zip


disk and D-NET. 

• Files for use on DigiCart II may be created 

on DigiCart/E, and exported on 



Zip disks or by D-NET. Export file types 
include Dolby


AC-2 and 16-bit linear files. 

• Serial control via 9-pin RS-422 is identical.
• GPI control by contract-closure is identical.
• File-naming conventions and ID numbering

schemes are compatible.

•  All DigiCart recorders employ professional 

XLR-3 connectors for analog and AES/EBU
digital audio, plus 75-ohm BNC connectors
for AES-3-ID and IEC-958 Type II
(consumer) digital audio. 

What does DigiCart/E do better
than its predecessors? 

• Network access to centrally stored audio 

from any location in the building. 

• Native wave (WAV and BWF) file formats 

for compatibility with workstations 

• Compatible with all sample rates from 44.1 

through 96K 

• Compatible with audio word lengths from 

16-bit to 24-bit.

• Converts any input sample rate or word 

length to any other, for storage. 

• Converts any stored file to any sample rate 

or word length for playback (real-time). 

• Records, plays and edits in standard wave 

(WAV) file format. 

• Front-panel Hot Keys for instant playback 

of cuts. 

• Easier navigation with buttons for Drive, 

Directory and File. 

• Much larger LCD permits easy browsing, 

displays five titles at once with continuous 

• Easy-to-ready interactive menu items. 

• Includes headphone jack with 

adjustable level 

• Integral rack mounting; only 2U (3




”) high.

How much delay occurs when
playing a cut from the file server?

Because a cut is immediately buffered in local
DigiCart memory when selected (as are all
Hot Keys), playback starts instantly.

What are the audio inputs 
and outputs?

• AES/EBU interfaces appear as XLR ports

with transformer isolation and also as 
75-ohm BNC ports (AES-3id-2000).

• Analog inputs are balanced on a XLR-3 

connector with pin 2 hot, Z=20K/leg, +4 
operating level, 16 dB of headroom to 

• Analog outputs are balanced, 

Z = 50-ohms/leg, +4 operating level, full
scale output = +20 dBu. Outputs have a rear
panel level trim. Audio connectors have gold
plated pins for low noise. 


Questions & Answers


background image

Is there a separate AES/EBU
reference input?

A separate AES-11 sync input is provided on
the rear panel. 

What sample rates does 
DigiCart/E operate at?

DigiCart/E can record and play at standard
sample rates of 44.1K, 48K, 88.2K and 96K.
DigiCart/E permits different sample rates to
co-exist on its hard drives. It is equally adept
at playing different rates, even when back-to-
back within a play list 

What digital audio word widths
does DigiCart/E operate at? 

Files may be created in either 16-bit or 24-bit
word widths. The internal A/D converter is
24-bits, but can also produce high-quality 16-
bit files. Digital audio inputs of any word
length are acceptable, and can be converted to
16 or 24-bit lengths before being recorded. All
conversions take place in real-time. 

Does DigiCart/E contain a 
sample rate converter?

A 24-bit sample rate converter (SRC) is
available on AES/EBU digital inputs and
outputs. It may be used to convert any input
sample rate to a preferred recording standard.
For example, a compact disc (always a 44.1K
audio stream) can be easily converted to 48K
and recorded as a 48K file within DigiCart/E.

The sample rate converter can also be used to
provide an AES/EBU digital output at a rate
different than that used to record the file. For
example, a music master may exist on hard
disk as a 24/96 file, but can still be played out
(in real time) as a 48K, 16-bit audio stream —
or any other sample rate.

DigiCart/E’s file flexibility permits audio to be
stored at its “native” sample rate and word
size, and then converted to a new standard on
a project-by-project basis.

Can digital audio word lengths 
be changed?

24-bit recordings may be dithered to 16-bit
for output, and 16-bit input data streams may
be recorded as either 16 or 24-bit words.

Is the Dolby AC-2 data format
from earlier model DigiCarts

Dolby AC-2 processing is carried forward
from the earlier DigiCart II to maintain file
compatibility. It is possible (though by no
means required) to record new files in that
format, and also to import and play DigiCart
II files in Dolby AC-2 format. 

Can DigiCart/E accept a 
feed from program distribution 
for recording? 

Each DigiCart/E recorder includes both stereo
line-level analog inputs and an AES/EBU
digital input. Either may receive a feed from a
control room output. Long-term logging is
possible if desired, as the maximum file length
is in excess of 32 hours. 

What audio file formats does
DigiCart/E record and play?

• Linear PCM in 16-bit or 24-bit WAV 

(or BWF) format

• Linear PCM in 16-bit DigiCart II format
• Dolby AC-2 as in DigiCart II

Can a DigiCart/E record directly 
to the file server? 

All DigiCart/E recorders can record directly to
the network file server, or to their internal
hard drive.

What editing operations are

Editing tools include head-trim, tail-trim,
and pre-roll time. Edit points may be rapidly
located with the weighted jog wheel, or by
typing a desired location. Edits are pointers
(for use within the DigiCart product family)
and are non-destructive. Other DSP-based
editing features are fade-in, fade-out, and


Questions and Answers, 



background image

Can cuts be looped?

Accurate editing tools make it easy to create
virtually seamless loops

What about working with
watermarked material?

DigiCart recorders employ 360 Systems Bit-
for-Bit technology in digital recording. Input
data received digitally will be replicated exactly
at the output, provided such data has not been
edited, sample rate converted, re-dithered to
another word size, or subjected to some other
DSP process such as fade-outs, etc. Standard
digital recording is always Bit-for-Bit. 

How does DigiCart/E handle 
data-compressed bitstreams
such as Dolby AC-3, Dolby-E,

360 Systems’ Bit-for-Bit digital architecture
guarantees that encoded data will not be
corrupted by internal machine processes.
Dolby Laboratories markets stand-alone
encoders for their proprietary formats. These
may be connected to 360 Systems’ DigiCart/E,
which will then act as an “audio data” recorder
for Dolby-encoded multi-channel audio.

Can stored cuts be locked or
password-protected after

Operators may invest a great deal of time
cutting a piece of music to fit one of their
shows. DigiCart/E can lock files to prevent
modification by other parties.

Are real buttons used for firing
audio playback?

DigiCart/E has real illuminated buttons on its
front panel and on its optional remote control.
“Hot Keys” also exist on both. 

Is there a playback stack or
“jukebox” (user-based
memories) for each DigiCart?

As many as 1,000 customizable “playlists” may
be created and stored on each drive. Each
playlist may contain an unlimited number of
cuts, and each can be given its own unique

name, representing a show, a user, or any other
identifying characteristic. Playlists can be
nested, looped, and single-stepped. 

Can pre-built playlists be
accessed from any location?

When playlists and audio cuts are stored on
the network file server, they can be accessed
from any location on the network. A sequence
of cuts may be developed in an edit area, and
then accessed for production on a stage.

Can files be transferred 
between DigiCart/E and the
network file server?

Files recorded to DigiCart/E’s local drive can be
transferred to the file server, or vice-versa. Note
that original recordings can be made to a local
drive, or to the server; there is no requirement
to move files except as a user convenience. 

How can saved cuts be imported
and exported to an external

DigiCart/E includes a Zip


drive, large

enough to archive a majority of file sizes
used in broadcast. The drive can also read
100-MB disks to exchange material with
DigiCart II recorders. 

Can DigiCart/E handle
“peripheral bus” or E-Mem
serial commands? 

Yes. A menu determines what format is
accepted by the 9-pin serial port.

Can DigiCart/E accept the 
same automation commands 
as earlier models?

Yes. Major automation systems such as
Harris/Louth will directly control DigiCart/E. 

What about GPI control?

Five GPI inputs are provided on a 25-pin D
connector: PLAY, STOP, RECORD, LOOP,
PAUSE and SECONDARY. All include an
open-collector output for operating an LED or

Can I play audio if the file
server goes down?

DigiCart/E contains its own internal hard
drive. Mission-critical locations such as Master
Control can keep “local” copies of important
cuts so they can always go to air. DigiCart/E
does not have to be connected to a network,
and also operates as a stand-alone
