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 described 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.
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 synchronization 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.
Mounting Steps 1 and 2 Step 1: Please put the converter module as illustrated 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).
Mounting Steps 3 and 4 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 operational.
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/PDIF digital inputs simultaneously! Analog XLR Outputs 1 2 3 The unit operating the module has to be switched off before connecting the converter via the XLR outputs with other units.
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 synchronization" on page 11).
Operation AD MODE Switch The AD MODE switch is used to set the desired bit mode and sample rate.The following list explains the respective switch positions: 16 Bit Mode E = AES D = DA C = WC B = 48 A = 44,1 9 = 96 8 = 88,2 Ext. Synchronization to AES clock Synchronization zum D/A converter Ext. Synchronization to word clock Int. Synchronization to 48 kHz Int. Synchronization to 44,1 kHz Int. Synchronization to 96 kHz Int.
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 identical, not synchronized sample rates inevitably have different timings - samples are ignored or read twice, usually audible als cracking.
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 loudspeakers or headphones. Example: High-quality conversion of a digital console's output signal.
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 highquality 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.
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).
