Two-wire to Four-wire interface
Model 45: The Model 45 is designed to interface a two-wire full-duplex party-line intercom circuit with a four-wire audio circuit associated with a matrix intercom system. Other specialized audio system interfacing applications can also be supported. The unit provides a full-featured two-channel interface which includes two hybrid circuits with automatic nulling capability. For flexibility, the Model 45 can be powered by the connected two-wire party-line circuit or by means of an external source of 24Vdc. When powered by an external source, the Model 45 is capable of supplying dc power to the two-wire intercom circuit. This unique feature allows direct operation of devices such as user belt packs. Audio level meters provide confirmation of system performance during setup and operation. Standard audio connectors are used for all input and output signals.
True condenser microphone
Superlux S125: Featuring a pressure gradient, 0.5" shock mounted condenser capsule, high SPL characteristics, a -10 dB pad, a low-cut switch, and conductive shielding to minimize RF and handling noise, the Superlux S125 delivers studio caliber qualities in a robust form factor designed for live performance. It is a cardioid condenser mic with a triple pop filter. Since the microphone's multistage pop filter does not use any foam components, it will maintain its high performance characteristics for years. Similarly, the pressure gradient capsule is shock mounted for low handling noise, and both the microphone's case and grille are conductive to resist RF interference from cell phones and other sources. The mic features a wide, flat frequency response that extends from 20Hz - 20kHz. The Superlux S125 has a switchable -10dB attenuator and a switchable 150Hz low cut filter. Gold-plated connectors sit between the microphone's capsule and electronics.
RTW Radio-Technische Werkstatten
10500X-Plus: RTW Digital Monitor 10500X-PLUS now incorporates ITU-compliant loudness display and full-screen mode. The RTW Digital Monitor 10500X-PLUS, a high-performance, cost-effective display system for monitoring digital stereo audio signals, now comes with an integrated loudness display in compliance with the ITU BS.1771 guideline. Further enhancements include a new full-screen mode for enlarged display showing the individual instruments in use. All current-production Digital Monitor 10500X-PLUS systems leave the factory with the new loudness display options included.
