Meridian Technologies SR-1A1C Overview

The DigiSlim SR-1A1C-1 Audio, Contact Closure Data Unidirectional Receiver from Meridian Technologies incorporates a digital encoding technology that receives 1 channel of audio (600 Ω, balanced-standard) 1 channel of contact closure over one fiber. This is multimode fiber system is fully compatible with the PC-based SpectraSmart Network Management & Diagnostic Software System. SpectraSmart supervises the operating parameters of the transmission system such as the status on video levels, sync, digital carrier detect, voltages, temperatures, optical levels, and more.

The SR-1A1C-1 Receiver comes as a standard 1-slot wide rack mount card and can be installed in any of Meridian’s desk chassis or in a 19” racking frame. This system can be configured in either star (module-to-rack) or trunking (rack-to-rack) configurations. It can also be transformed into a standalone module by utilizing an SR-500/S (standard configuration) or an SR-1000/S Chassis, or 1/2 slot desk or wall mount chassis.

Note:
The SR-1A1C-1 Receiver requires the ST-1A1C-1 Transmitter at the transmitting end.
