Description
The EOL Box is an end-of-line termination for speaker circuits supervised with a 20 kHz pilot tone. It goes at the farthest end of the loudspeaker circuit. The box is reactive at 20 kHz, so HiQnet Audio Architect software can measure the pilot tone current, and a change in that current shows the line has been opened or shorted.
The pilot tone is mixed in with the program audio. Crown DCi Network and Dante amplifiers and USP4 family CTs amplifiers can generate it, and their DSP can let the tone bypass the internal speaker processing.
Features
- End-of-line termination for 20 kHz pilot tone line monitoring
- Lets the system detect open and shorted speaker lines
- External switch selects a 10 ohm or 5 ohm load at 20 kHz
- Works with the pilot tone from DCi Network, DCi Dante and USP4 family CTs amplifiers
- Monitored in HiQnet Audio Architect software
Installation and Setup
- The box mounts with a large tab
- The box is not weatherproof and should not be mounted outdoors
- A circuit with branches may need more than one box: start with one at the junction, then add one at the end of each branch that is still not detected
- Audio Architect holds upper and lower current limits for each channel, set after testing the system, and reports an error to the aux port or the network when a reading falls outside them
Specifications
- Monitoring method: 20 kHz pilot tone
- Load at 20 kHz: 10 ohms with the switch to the left, 5 ohms with the switch to the right
- Placement: Farthest end of the loudspeaker circuit
