Studio Technologies is introducing its Model 46 interface, designed to interface two-wire full-duplex party-line intercom circuits with four-wire audio circuits associated with matrix intercom systems.
The unit provides two independent full-featured two-channel interfaces. Each interface contains two hybrid circuits, which include automatic nulling capability.
Multiple LED level meters allow continuous monitoring of the input and output signals. DC power sources eliminate the need for external intercom power supplies, according to the company.
Studio Technologies also is introducing Models 761 and 771, a monitor system developed for Fox Broadcast’s new facility in Houston; and StudioComm for Surround Models 76 and 77, which offer upgrades to Models 68A and 69A. The inputs are AES3id (unbalanced) digital audio, while the outputs remain analog. Multiple Model 77 user control surfaces can be connected.
