Extra Information Hi, I've a Canford 20-181 Pro Interface for sale. This allows you to connect -10dB unbalanced cassette decks/music players/ipods etc to professional balanced gear. It's bidirectional so will also allow pro gear to feed unbalanced equipment.
It's in good condition and ready for a new home!
Manufacturer's info: a bi-directional stereo interface for matching “semipro” or “domestic” equipment, inc 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 multiturn gain control 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.
