Security Advices 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 descri- bed from page 5. In case of queries please contact an expert. Product Description 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 autom

Product Description 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 synchroniza- tion please refer to the chapter "Operation", from page 11. General Information Mounting The SPL converter module 2053 is exclusively offered as an option for certain SPL units. We especially advise electronically inexper

Mounting Steps 1 and 2 Step 1: Please put the converter module as illust- rated on the unit top and remove the screws of the cover from the back of the upgrade unit. Socket Step 2: Please remove the mounting of the wiring on the back of the cover (eventually cut off the silicon). Socket Connector 6 24/96 AD-DA Converter 2053

Steps 3 and 4 Mounting Step 3: Connect the cable carefully, without turning, to the socket of the converter. Guideways on socket and plug exclude a wrong connection. Sockel Step 4: Put the converter, as illustrated, without lateral turning in the unit (circuit board above, connection sockets on the head) and connect it with the screws of the cover. The converter is now opera- tional. 24/96 AD-DA Converter 2053 7

Connections 2 3 1 The converter module provides analog, balanced XLR outputs (1), digital XLR I/Os (AES/EBU) (2) and digital S/P-DIF I/Os (3). In case of using the S/P-DIF output as a WC/AES SYNC input, the S/P-DIF output is no longer available. Important: please never use AES- and S/P- DIF digital inputs simultaneously! Analog XLR Outputs The unit operating 1 2 Wiring XLR Output 3 1 = GND, 2 = hot (+), 3 = cold (-) the module has to be switched off before connecting the Balanced Unbalanced

Connections Digital I/Os AES/EBU: Inputs and outputs according to the AES/EBU specification for the connection of all digital units specified in accordance to AES/EBU. S/P-DIF: Alternatively to the digital XLR-sockets, the S/P-DIF I/Os can be used for the connection of digital units. The S/P-DIF output (=WC/AES SYNC INPUT) can also be used for external synchronization via external clocks (refer to "Applications, external synchroniza- tion" on page 11).

Operation External Synchronization External Synchronization (Connection via W/C-AES SYNC INPUT) is required when several signals must be brought together within a chain of digital units, e.g. when connecting several digital units at one console. Since the sample frequencies are never exactly iden- tical, not synchronized sample rates inevitably have different timings - samples are ignored or read twice, usually audible als cracking. By supplying all signal sources with a common frequency, all si

Applications CHANNEL ONE: Using both converters Referring to the CHANNEL ONE, the separate use of both converters can be for example the conversion of digital signals independent from the A/D converter and to reproduce them in best tonal quality on louds- peakers or headphones. Example: High-quality conversion of a digital conso- le's output signal. Another application is the high-end conversion of digital signals for the further analog processing (refer to "Operation, analog processing of a dig

Applications Monitoring in 24Bit/96kHz A high standard of monitoring is necessary for judging the recording quality. Therefore all digital signals have to be converted into analog signals to allow reproduction on loudspeakers or headphones. The A/D converter stage is equipped with high- quality components and ensures excellent tonal results. We recommend to use the SPL converter rather than the converters found in DAT recorders, sound cards or digital consoles. Analog processing of a digital sig

Applications Example 1: Processing a sampler's signal Connect the output of the sampler via AES/EBU or S/P-DIF interface with the input of the converter. The adjustment described in the section above now allows to process the sampler's signal. If the processed signal is to be returned digitally converted to the sampler, the A/D converter has to be synchronized to the D/A converter (= external synchronization; the D/A converter is the source clock for the A/D converter). In this case, please set
