24/96 AD-DA Converter 2053
• Please consider referring the installation of the unit
operating the converter the safety information in the
corresponding operation instruction.
• Please carry out the self-installation only as described from page 5. In case of queries please contact an
expert.
The SPL converter module 2053 combines separately
useable A/D and D/A converters,with a wordwidth up
to 24 Bits,and a Sample-rate of up to 96 kHz.
The D/A converter processes up to 24 Bits automati-
cally,as well as sample-rates from 32Bit to 96 kHz and
is equipped with high-quality, balanced XLR outputs
(+ 12 dBu).
The A/D converter supports 16 and 24Bit formats
and works. The reduction from 24Bit to 16Bit is
processed with the Dithering-method: the "missing"
lower 8Bit is not cut off,but rather "included" in the 16
Bit format. This ensures that quietest passages are
preserved.
Internal Synchronization: The converter module
allows to choose 5 different clock sources via the AD
MODE switch.The internal sample rates (96 kHz/48kHz
and 88.2 kHz/44.1kHz) are Quartz-generated.

External synchronization: For synchronization with
external sources, AES-data or Word-Clock signals can
be used as sync sources. Alternatively the A/D
converter can be synchronized to the data adjacent to
the D/A converter. For internal/external synchronization please refer to the chapter "Operation", from
page 11.
The SPL converter module 2053 is exclusively offered
as an option for certain SPL units.We especially advise
electronically inexperienced users to contact an
expert in case of queries.
• In order to avoid static loads, please deactivate the
GND-Lift switch on the back of the unit that is to be
upgraded and touch its case.
• Now pull the power cord out of the socket on the
back of the unit operating the converter module.
Please also remove all other cable connections.
• Treat the converter carefully. Please make sure that
you only touch the front panel or the sides of the circuit board in order to avoid contact with parts on the
circuit board.Never force any parts when connecting
unit and converter module.
