Calrec Type R - Core I/O (UR6500)

•     Calrec's Type R has a simple 2U core at its heart, with integrated I/O resources to get you up and running immediately.
•     A single core can power up to three independent mixing environments, with no sharing of DSP resources.
•     Type R Cores can be purchased in pairs to provide a fully redundant system.
  

The UR6500 Type R core is designed to provide the DSP, Routing & Control for up to three Type R consoles. In addition, the Type R Core has a base level of I/O, GPIO, and one or two optional AoIP interface modules fitted internally, allowing for a large amount of stream connectivity with other AoIP devices.

Front Panel

The front of the core displays on the left hand side the LED signal status indicators for the Analogue and AES inputs and outputs. In addition the 48V phantom power LED status indicators for the analogue inputs and the SRC LED status indicators are shown.

On the right hand side are shown the AoIP LED status indicators and a further column of System LED status indicators and to the right of these are two 6.35mm (1/4”) headphone sockets for monitoring usage. Next to these are an Ethernet Setup port and USB connector.

The Setup port is used to configure the Core whilst the USB connector is used to recover/reinitialise the core system from a USB memory stick in the event of connection failure. At the far right is a Reset switch which restarts the processor without altering any stored settings.

Rear Panel

The rear of the core is arranged into a top row and a bottom row.

The top row contains the external system connections which from left to right are AoIP1 and AoIP2 RJ45 interfaces which are connected to internally fitted optional JG6393 AoIP modules (with redundant Primary and Secondary connections). Each of these modules can provide up to 256 channels of streamed audio in either direction. Next to these are a set are 4 BNC connectors labelled Sync 1/2 In and 1/2 Out. These are discussed in the Sync section.

To the right of the BNC connectors are a secondary USB connector and a block of 8 RJ45 connectors which connect to the various surfaces via PoE+ switches. Typically each of these connect to a separate PoE+ switch interfacing to a number of Fader, LSP and SSP panels.

More than one connection is usually made to each console area to provide control diversity. For instance a 24 fader console may be powered from two PoE+ switches connected back to the core, with each switch powering and data transferring to/from 2 x IM6413 fader panels and 2 x MU6411 Large Soft Panels.

Further to the right is a DVI debug port which is reserved for development use along with a PRI/SEC switch.

The bottom row is dedicated to I/O, GPIO and Power. There are 4 x 25 way ‘D’ Type connectors carrying audio using AES59/ Tascam® pinout format and the audio is also carried as pairs of Analogue inputs, outputs or AES I/O ports, on 4 x RJ45 connectors per 25 way ’D’ type connector.

The four connector areas from left to right provide:- 8 Mic/Line Analogue inputs with phantom power, 8 Analogue Line Outputs, 4 AES Input ports with SRC and 4 AES Output ports.

Further to the right are 4 x RJ45 connectors for GPIO interfacing. The upper two connectors each provide 6 x GPI opto input circuits each and the lower two connectors provides 6 x GPO opto output circuits each.

On the bottom row of the core are 2 x IEC power sockets labelled PSU 1 and PSU 2, either of which can power the console. Together they provide power redundancy. The IEC inputs should be fed from separate AC sources to protect against external power loss. In the event that only one AC outlet is available, power should be fed via an IEC Y-Split cable to provide redundancy against internal PSU failure.

Metal clips provide retention to further protect the IEC connectors from working loose. These clips fit snug around large IEC connectors with screw in terminals inside for wiring. The clips may not provide adequate retention on their own for some pre-fabricated IEC connector types. If there is concern over the connectors working loose during transit, we recommend that IEC sockets with built in latching are used.
