The Eddystone E2075 Broadcast Audio Fail & Changeover Unit provides seamless automatic and manual transmitter or drive changeover capabilities with both local and remote control. Here’s a detailed overview of its features and specifications:
Features:
- Versatile Changeover Functionality: Capable of automatic and manual operation, with controls for both local and remote control. Internal changeover relays can handle a maximum power of 200W at 100MHz.
- On/Off (Mute) Outputs and Status Monitoring: Equipped with on/off (mute) outputs and status monitoring inputs for connection to two transmitters/drives and two receivers (in re-broadcast systems), enabling effective control.
- Wide Range of Transmitter Configurations: Supports various transmitter configurations, including Tx1 or Tx2 to Antenna or Load, Tx1 or Tx2 to Antenna system only, and Tx1 + Tx2 to Antenna systems or Load.
- Internal Option Switches: Allows for selection of digital or analogue status monitoring, adjustment of the “good” status level, polarity settings for input status and output controls, and customization of associated delays.
- Automatic Failover: Utilizes micro-controller based software control with up-datable ‘flash’ memory. In case of a software fault, comprehensive hardware/software ‘watchdogs’ illuminate a front panel CPU ALARM LED and switch off other LED indications to prevent erroneous readings.
Specifications:
- RF Interface Ports: 50Ω nominal with four TNC Connectors for Tx1, Tx2, Antenna (output), and dummy load.
- Power Level: 200W maximum up to 100MHz, de-rating to 100W maximum at 500MHz, using internal relays. External relays/switches can be fitted to meet system requirements.
- Controls: Eight tactile momentary switches for selecting Operational Mode, Tx1/2 On/Off, and Tx1/2 to Antenna or Load.
- Remote Control and Monitoring: Rear panel 25-way D socket for parallel control and monitoring of major functions and status.
- Transmitter and Receiver Control and Monitoring: Connections provided for mute line and status line from each transmitter/receiver, with internally adjustable polarities.
- External Switch/Relay Control and Monitoring: Parallel control and monitoring connections for external switches or relays.
- Power Supply (AC): 85-264V AC (universal input, switched mode, power supply).
- Ambient Temperature (Operating): 0°C to +45°C.
- Relative Humidity (Operating): ≤90% RH, non-condensing.
- Altitude (Operating): Up to 3000m a.s.l.
- Dimensions: 1U with 280mm intrusion into rack (including connectors).
- Weight: Approx. 3.5kg.
- Warranty: Limited 5 Years.
This unit provides reliable and flexible failover capabilities for broadcast systems, ensuring continuous operation and seamless transitions in case of equipment failure or maintenance.
