SHDE119/319

The digital audio shuffler+delay was conceived for the simple handling of AES3-audio signals. Our design focus was to create a transparent and simple shuffler function layout. The matrix configuration can be instantaneously recognized. Through the selection of a matrix point one can change  the dB-gain and delay time. AES-inputs can be distributed to 4 AES-outputs. In case of power failure will one of the outputs automatically  connect with the proper input.   Two methods of operation are possible - Matrix and Mix Mode. AES-status bits conduct concurrently over the delay and the matrix. Only by mixing of the AES-channels are the  C,U,V-bits internally generated.  Through a data bus it is possible to interconnect up to 16 shufflers. It is also possible to adjust the shuffler over an external keyboard or a PC with a WEB-Interface.

AES3DDA216,414

This digital distribution amplifier (DDA) is designed for the easy distribution of AES audio signals. The distribution of the AES3DDA216 AES signals can easily be configurated with the TTL signal output and inputs on the DIN41612 connector. The max. AES3 distribution is one AES input to six AES outputs. There are two DDA variants to choose; 2x AES3 input with 2x 6xAES3 outputs and 4x AES3 input with4x 4xAES3 outputs If one needs a signal regeneration e.g. transmission over 300 meters, a version with AES signal refreshing and reclocking is available.

AES11 TV-Sync

The AES11 synchronizer is developed for the simple synchronization of AES based equipment in an digital audio domain. The synchronization can be derived from an video signal like an Black Burst or Color Bar signal, an
AES signal or a word clock signal. The distribution of the synchronized AES clock consist of up to 12 AES Outputs and up to 10 word clock Outputs. In case of a sync signal error, an alarm output will be triggerd and the AES clock distribution will be derived from an internal AES refernce.

AES3DSP216

This DSP platform is designed around a powerful 32Bit floating point DSP with an external memory up to 64MByte SDRAM. There is a maximum 87sec. storage for both AES channels, four audio channels at a 48kHz sample rate. This platform is pin compatible with the digital distribution amplifier (DDA Art.No.: AES3DDA216) It is easy to change from a DDA to a DSP platform. e.g. standard audio delay function,  With the futuristic design it is practicable to adapt this platform  only by changing the  firmware. Through a data bus it is possible to interconnect up to 16 DSP platforms.

TRDE216-LP

The  AES3 Multiformat Tracking Delay  is able to perform a fix Delay of a maximum of 1.3s and an additional delay from max. 40ms following an Video Frame Store timing signal for two independent AES3 audio channels .  Following Tracking Delay control signals are possible:  PWM Signal (Crystal Vision, ...), 24.576MHz or 27MHz Control Signal (LEITCH) , Customized control signals can be implemented on request . One importend feature is the capability to dedect NON-PCM-Audio, which are described in the SMTPE337M-2000 standard. (MPEG, AC3, ...) This non PCM audio data will be pass through without any modification.

SRCDU3296-NPD

This sample rate converter (SRC) is designed for an easy change between different sample rates. This SRC consists of two AES inputs, two AES independent synchronisation inputs and two AES output blocks. Any output block consist of four equal AES outputs (Fig.2). The  AES outputs can be fixed to  the standard sample frequencies (32kHz, 44.1kHz, 48kHz, 96kHz). It is possible to lock the AES outputs to one of the AES synchronisation inputs. In this case a sample rate between 28,4kHz  and 100kHz can be set. A new feature is the capability to dedect NON-PCM-Audio, which are described in the SMTPE337M-2000 standard. This non audio data will be pass through without any modification.

LWL119AES

The LWL transceiver was conceived for the simple distribution of up to 128 digital audio channels and up to 24 serial data channels over a fibre optics network. All digital audio channels have a word length of 24bit and a sample frequency of 48 kHz. The main sample frequency can be locked to an AES sync reference. To obtain a definable synchronisation in the LWL network, it is possible to establish a master slave LWL-system. The serial data channels are transparent in nature and the transfer rate is up to 300kbps per data channel. Is there a need for a higher data transfer rate, it is possible to multiplex the data channels. The physical layer of the serial data channel can be selected over an IF module (RS232, 422…etc.). The fibre optic transmission can be distributed over a multi mode or single mode duplex cable, depending on the LWL module used in the LWL AES transceiver design. A main benefit of using the AES/EBU LWL-Transceiver is the simple distributions of up to 128 digital audio channels and up to 24 serial data channels over an single fibre optic duplex cable, which can provide transmission links up to 1500m with multi mode and up to >10km with single mode. With conventional AES transmission links it is only possible to provide distances up to 300m (48 kHz sample rate) without refreshing the AES signal. And there is the risk of building ground loops into the audio domain, which can be avoid by using the AES/EBU LWL transceiver.
