Description
For applications that require Dante or AES67 networked audio, the Crown DriveCore Install DA Series provides a balanced combination of output power, channel count and speaker load flexibility along with proprietary DriveCore® technology for superb efficiency and exemplary audio quality. The DCi DA Series includes a high-powered DSP with JBL speaker tunings, network control/monitoring, and the ability to drive 2/4/8/16 ohm, 70V and 100V speaker loads. The amp’s advanced capabilities and support for Dante Domain Manager makes it perfect for installations that have standardized on Dante for networked audio transport. This amplifier is EN 54-16 Compliant for life safety applications.
The EOL box is used as an End of Line (EOL) termination in audio systems that use a 20kHz pilot tone to detect open and short conditions. The termination is placed at the farthest end of the loudspeaker circuit. Unlike most loudspeakers the EOL box is reactive at 20kHz such that the resulting current can be measured using HiQnet Audio Architect™ software. If the circuit is either opened or shorted, the measured 20kHz current will change. The EOL box presents either a 10Ω or 5Ω load at 20kHz, selectable using an external impedance switch. This method requires the 20kHz pilot tone to be mixed together with the audio. The pilot tone can be generated within the DCi Network or Dante family of amplifiers and the USP4 family of CTs amplifiers. Additionally the DSP built into the DCi Network, Dante and USP4 has the ability to allow for the pilot tone to bypass the internal speaker processing.
