Calrec launches new fixed-format I/O boxes

At NAB2007, Calrec launched a new range of fixed-format remote audio I/O boxes.

Ranging in size from 2RU to 4RU, the new I/O boxes complement the company’s existing modular remote I/O box. All of the new remote boxes include a built-in power supply redundancy with dual IEC power connections.

Calrec showed the first three boxes from this range: the AD5603 and AD5608, both 2RU analog I/O units; and the JB5607, a 3RU unbalanced AES I/O unit. The AD5603 consists of 24 mic/line inputs and eight line outputs, while the AD5608 consists of 12 mic/line inputs and four line outputs. Both come with phantom power indication and a tricolor signal LED indicating whether audio is present, normal or at clip.

The JB5607 consists of 32 AES inputs and 32 AES outputs on BNC connectors. The AES unit is also available as a 110Ohm XLR-based 4RU unit.

The boxes link to the Calrec Hydra network using dual Cat 5e GigE ports for audio and control redundancy at distances up to 295ft.
