552 User Guide and Technical Information

Press and hold the Battery Check button to have SVEN announce the remaining card space available

in headphones. SVEN automatically announces the remaining time when 15, 10, 5, and 2 minutes are

remaining on the SD card.

File Format

WAV (Broadcast WAV)

The 552 records two-channel, polyphonic AES-31 Broadcast Wave formatted audio files. These files

place additional information in the file header, called the Broadcast Audio Extension data chunk, and

in the iXML chunk. Audio editing software that does not recognize this additional information will

ignore it and read the file as a standard WAV file. Values recorded in the BEXT and iXML are:

• time code stamp

See Time Code

• time code frame rate

• time code user bits

• original date and time

• bit depth

• sampling rate

• track names

• take number

• file name

• machine serial number

• software version

MP3

MPEG-1 Layer III is a lossy compression algorithm, often used for music and transcription recording

purposes. The 552 records two-channel MP3 audio files with the following data rates.

• 64 kb/s

• 128 kb/s

• 192 kb/s

• 320 kb/s

Bit Depth

When recording WAV files, the 552 records either 16 or 24 bit files. 24-bit recording provides greater

dynamic range and addition headroom for signal peaks. Sound Devices recommends 24-bit record-

ing for all critical production.

Bit Depth and Dynamic Range

Bit depth defines the digital “word length” used to represent a given sample. Bit depth correlates

to the maximum dynamic range that is represented by the digital signal. Larger bit depths accom-

modate more dynamic range. A quick estimate of the maximum dynamic range capable of being

represented by a given word length is dynamic range ~= no. of bits x 6 dB. Bit depth is an exponen-

tial measure (exponent of 2), so as bit depth increases, the amount of data it represents increases

exponentially. The majority of field recording is done with 16-bit audio, therefore each sample is

represented by a digital word of 2^16 (65,536) possible values. 24-bit audio has a word length of 2^24

(16.7 million) possible values per sample.

Sampling Rate

The 552 records WAV files at the sampling rates selected below. The sampling frequency is set in the

Setup Menu.

• 44.1 kHz

• 48 kHz

• 88.2 kHz

• 96 kHz

Sound Devices recommends 48 kHz sampling for all 552 production applications. Sampling rate op-

tions are limited to 48 kHz and under when an MP3 or a Time Code to Track option is selected. If the

sampling rate is set to a higher rate when an MP3 option or a Time Code to Track option is selected,

the sampling rate defaults to 48 kHz.

Sampling Frequency and Audio Bandwidth

The sampling frequency is expressed in samples per second (hertz) and defines the number of times

in a second that an analog audio signal is measured. Sampling frequency determines the audio band-
