    Installation and Mounting Crest Audio CKd Power Processing amplifiers are configured to a standard set-up at the factory. They are functional and ready to use ‘out of the box.’ All controls and input/output connections are clearly labeled. Units are shipped either with a network module or blank panel over the module bay.

  • Page 13: Amplifier Operation

    CKd Owner’s Manual Amplifier Operation Input Sources CKd Power Processing amplifiers are designed to accept a balanced input signal. For use with an unbalanced source, please see the diagram below. Further audio routing can be configured using Nx modules via software. Output Connections Speakers are connected using the Output Barrier Strip connectors.
  • Page 14 CKd Owner’s Manual Mode/Gain Selection Switch (100V, 70V, LowZ) The three-position gain select switch found on the rear panel of the CKd is used to set the overall gain and protection thresholds (ACL & IGM) of the amplifier channels. The ‘100V’ position set’s the channel gain to x50 with a 2.0V sensitivity.
  • Page 15 CKd Owner’s Manual With two SPST momentary switches, one switch must be wired across the “On” STO connections are and “Com” pins, and the other switch must be wired across “Off” and “Com” optically isolated so pins. When the first switch is depressed, it shorts the “On” and “Com” pins, connecting amplifiers from different AC feeds turning the amplifier on.
