Providing isolation between input and output, these are available as eight-channel units, for either 110 ohm balanced or 75 ohm unbalanced circuits. Each channel has a 1:1 transformer, balanced circuit versions have an 'earth-lift' switch. They are housed in a 1U rack-mounting enclosure with innovative mounting options.
The balanced circuit version has XLR connectors for input and output, one female, one male, located in pairs on one face. Earth-lift switches for each channel are located on the opposite face of the fully-screened case.
The unbalanced circuit version has BNC female connectors for input and output, located in pairs on one face; there is no earth lift facility on this type.
They are designed to be mounted in a number of different ways within a 19-inch rack, acknowledging that they are utility products that may require no operational access. Detachable rack-mounting 'L- brackets' are included, which can be fitted at either face. Brackets may be fitted so the unit mounts flush, or recessed by 30mm, 60mm or 90mm.. A lacing-bar is provided, with a choice of mounting positions. Note that the lacing-bar cannot be fitted when the unit is mounted recessed by 90mm. Alternatively, the brackets can be fitted at right-angles to the box allowing vertical mounting (either way up) either flush with the rack-verticals or at a recess depth of approximately 30mm, 60mm or 90mm (or 120mm or 150mm). The vertical-mounting option allows space within a rack behind patch panels or other equipment to be utilised saving valuable front-of-rack area.
Units are finished in black, printed with channel identification numbers on both connector and switch faces and fitted with snap-on cover designation strips. Templates for printing designation strip labels, available as a DWG file for AutoCAD and compatible applications, can be downloaded from the appropriate product page on the Canford website.
Spare designation-strip paper inserts (not suitable for printers) and clear covers are available.
