Questions and Answers,

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.

cont.

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

available?

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

available?

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

gain-adjustment.
