CANFORD PRO-INTERFACE MK 2 - Free standing

A bi-directional stereo interface for matching “semi-pro” or “domestic” equipment, including cassette machines, video recorders and DAT machines for example, to the higher audio levels and differing connection methods of “professional” environments.

This rugged design is constructed in an extruded box, with four XLR connectors on the front panel. Two are female, connecting to high-impedance, electronically-balanced, line-level inputs, whilst the remaining two are male, fed from electronically-balanced low-impedance, line-level outputs. These four connections are to interface with the “professional” environment, but may also be connected unbalanced without loss of level. They are designed to connect with up to 100m FST cable (or similar) to standard line-level (low source, high or “bridging” load impedance) interfaces.

The rear panel has four RCA(phono) connectors to connect to the “semi-pro” device. All are connected unbalanced, and have an adjacent associated multi-turn gain controls to adjust the operating level of the attached device to the line-up level of the “pro” environment. An IEC inlet with fuse provides connection to the mains supply.
