{"product_id":"sonifex-rb-dd4-4-channel-digital-audio-delay","title":"Sonifex RB-DD4 | 4 Channel Digital Audio Delay","description":"\u003cp\u003eThe RB-DD4 4 channel digital audio delay allows you to delay 4 mono channels of audio independently or together. Each channel delay is user selectable from multiples of common video frame rates, or a user defined value set via the serial interface. The unit is perfect for synchronising audio to video which has been delayed by processing latency. Using a front panel button, you can select which channel needs to be delayed. There is also an ‘ALL’ option which allows the selected delay to be applied to all channels. Then using another front panel button you can select the length of one frame of delay and the multiple of frames to delay by. The connectivity is incredibly flexible, allowing three different types of connection to each input and output including AES\/EBU, S\/PDIF and TOSLink. All three different types of output can be used simultaneously. There is a monitor socket on the front panel which allows you to listen to each mono channel, by front panel selection. Pairs of channels can be monitored (1 \u0026amp; 2 or 3 \u0026amp; 4) using a rear panel stereo option. There is also an option to attenuate the monitor by 12dB selectable by rear panel DIP switch. Audio presence is detected and displayed for each channel around the INPUTS 1 \u0026amp; 2 and INPUTS 3 \u0026amp; 4 buttons. The flexibility continues with many audio synchronisation options. The digital audio output can be synchronised to either input, an additional AES\/EBU reference input, a TTL wordclock BNC input or an analogue\/SDI video feed if used with an additional RB-SYA or RB-SYD board. Also the output can be synchronised to an on-board master clock, with a selectable frame rate. There are warning indicators on the front panel for loss of lock on both inputs and for the selected external synchronisation. Selectable synchronisation modes are as follows: Master Mode In this mode the digital output sample rate is simply set by, and locked to, the internal on-board clock generator. No sync signal is used or required. Auto Sync Mode In this mode the digital output sample rate follows the selected sync input. When the sync signal is not present the output sample rate will be set by, and locked to, the internal on-board clock generator at the selected output frequency. Auto Lock Mode In this mode no output will be generated until lock is achieved with a sync signal. The digital output sample rate now follows the sync input. If the sync signal is removed then the output sample rate will be set by, and locked to, the internal on-board clock generator at the closest frequency available to the previous sync input. Slave Mode In this mode the digital output sample rate follows the sync input. When the sync signal is not present the digital output is turned off. A powerful feature of the RB-DD4 is that by using the Sonifex SCi serial software, the unit can be programmed for different delay durations, levels and switching functions so that you can program the unit for your specific application. A rear panel DIP switch configures the unit to be controlled serially. Contact Sonifex for further information if you have a particular requirement that isn’t catered for by the RB-DD4 as standard. The RB-DD4 has been designed to have a passive signal path through the main input, so if power to the unit fails, signal inputs 1 \u0026amp; 2 are routed to outputs 1 \u0026amp; 2 and signal inputs 3 \u0026amp; 4 are routed to outputs 3 \u0026amp; 4. This is essential for applications such as installation at transmitter sites, where a power failure to the unit should not prevent the audio input signal from being output to the transmitter. Please note that this is not true for the TOSLink outputs which are muted.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAES\/EBU, S\/PDIF, TOSLink (optical) digital inputs and outputs.\u003c\/li\u003e\n\u003cli\u003e4 channels of independent or linked delay.\u003c\/li\u003e\n\u003cli\u003ePreset or user-defined frame length.\u003c\/li\u003e\n\u003cli\u003eFlexible input \/ delay routing.\u003c\/li\u003e\n\u003cli\u003eFlexible output sync options and modes.\u003c\/li\u003e\n\u003cli\u003eOptional RB-SYA or RB-SYB video sync boards.\u003c\/li\u003e\n\u003cli\u003eRS232 Serial control (Sonifex SCi software).\u003c\/li\u003e\n\u003cli\u003ePassive signal path for power failure routing (AES\/EBU or S\/PDIF).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eIn the broadcast chain to remove lip-sync errors, post production to synchronize audio when monitoring video signals, time zone delay to provide +1 hour programme feed.\u003c\/p\u003e\u003ch3\u003eProduct Category\u003c\/h3\u003e\u003cp\u003eDelays \u0026amp;
