1. Device overview 1.1. Front panel The connectors “Cat5 Connection 2“ are only available in the 64 channel version (ADX-64A-PRO). 1.2. Rear panel The connectors „ADAT 5-8/WC“ are only available in the 64 channel version (ADX-64A-PRO).
User's Manual 2. Typical application 2.1. Digital snake (32 channels) The diagram below shows a typical application of the ADAT Multicore Extender: One Cat5 cable is used for both the transmission of 24 channels from the stage to the mix console, and 8 channels in the opposite direction. All 32 channels are also fed into a monitor console and into a multitrack recorder. Other examples setups can be found in chapter 10. Example applications.
ADX-32A / ADX-64A-PRO 3. Important safety notes 3.1. Cat5 connections Use the Cat5 cable ONLY between ADAT Multicore Extenders! NEVER connect an ADAT-Multicore Extender to any Ethernet networking device (PC, Switch, other network equipment)! The ADAT Multicore Extender and/or the networking device may be DAMAGED! 4. Introduction 4.1.
User's Manual For audio distribution to several places, up to 32 ADAT Multicore Extenders can be daisy-chained together. This feature can be used for complex setups, e.g. multiroom audio distribution or the connection of additional monitoring equipment. Each ADAT stream can be fed into the Cat5 at an arbitrary place and is then distributed to all other connected devices. All ADAT connections work completely independent of each other.
ADX-32A / ADX-64A-PRO 5.3. Latency Latency has – in contrast to traditional analog systems - always been a topic in digital audio technology. High latency can lead to unwanted effects, such as phasing, hall, echo etc. and can seriously affect audio performance. One design goal of the ADAT Multicore Extender was to build a system offering one of the lowest latency values on the market. By design, other digital snake solutions (e.g.
User's Manual 6. Front panel connections 6.1. Cat5 Connection 1 Cat5 cable carrying ADAT connections 1-4. Jacks “A” and “B” are electrically paralleled. Depending on the number of jacks used, the push button “Termination” has to be set: 1 cable = “ON”, 2 cables = “OFF”. See also 8.1. Cat5 Termination. NOTE: Redundant connections (the connection of two units with two cables over A and B at the same time) are not supported! This would lead to signal loops causing undefined current flow. 6.2.
ADX-32A / ADX-64A-PRO 7. Rear panel connections 7.1. Power Input Power supply of the device. Use only the supplied DC adapter or a replacement with the indicated voltage, power, polarity and matching connector (see 12. Specifications). The input has a reverse-polarity protection. If the Power LED does not go on when a DC adapter is connected, check the polarity (inner positive). The second module in the 64 channel version is internally supplied with power. 7.2.
User's Manual 8. Settings An overview of all switch settings can be found in 11. Settings overview. 8.1. Cat5 Termination For proper operation, the termination (push button on the front panel) has to be set correctly. The required setting depends on the position of the ADAT Multicore Extender within the cable snake: At devices on the end of a Cat5 snake (all devices having only one cable plugged in either A or B), the termination has to be switched ON.
ADX-32A / ADX-64A-PRO Output (DIP switch in upper position = ON): The ADAT connection is configured as output (the sender is active). Data received from the Cat5 cable is output on the “Output” jack. Within a system, for each ADAT connection there must be only one sender (input) device. 8.3. Transmission direction (ADAT 5-8), ADX-64A-PRO only The transmission direction (input or output) for ADAT connections 5-8 and the wordclock signal is set by the DIP-switches 1-4. 8.4.
User's Manual The above configuration with only one cable end terminated is possible if the transmitter device is located at the other end of the cable and has the advantage of lowering the driver's load. However, if you have the ADAT Multicore Extender connected in the middle of the cable, both ends must be terminated.
ADX-32A / ADX-64A-PRO 9. Wordclock synchronization 9.1. General concept For all devices within a digital audio system, it is required to share a common clock. This ensures that data processing on all channels and on all devices is done at the same rate. Without a common clock, the individual clocks would drift apart with time due to small skew between even crystal clocks.
