Page 4: Introduction
Introduction. Congratulations on your purchase of a Crest Audio CK family of Power Processing amplifiers. Please read this manual carefully (espe- cially the the “Important Precautions” section located inside the front cover) as it contains information vital to the safe operation of the amplifier. -
Page 5: Quick Set-Up
Unpacking. Upon unpacking, inspect the amplifier. If you find any damage, noti- fy your supplier immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials. Should you ever need to ship the unit back to Crest Audio, one of its offices, service centers, or the supplier, use only the original factory packing. -
Page 6: Rear Panel
Rear Panel. Module Bays & Modules. The rear panel of CK Power Processing amplifiers provides three bays (Input, Network and Output/Power) configured to accept inter- changeable plug-in modules. Your amplifier may have been factory- configured with some of the optional modules. In this case, info on the relevant modules will be enclosed in the amplifier box, or in a separate binder. - Page 7 Channel A’s output, while signal at Channel B’s input pro- duces output at Channel B’s output. (Recommended minimum nomi- nal load impedance for stereo operation of CKS Series amplifiers is 4 ohms per channel; 2 ohms per channel for models CKS 800-2, 1200-2, and 1600-2.

Page 8: Input Bay
Input Bay. Input Module Connections and Controls. Input barrier strips have a 0.325" (8.3mm) center and 0.270" (6.9mm) lug space. For connecting to the input barrier strips, a wire gauge between 14 AWG (2.5mm ) & 24 AWG (0.25mm lugs (Panduit Part No. PNF 18-6LF-C or equivalent) are recom- mended. -
Page 9: Network Bay
Network Bay. Network Module Controls/Connections. CK Power Processing amplifiers come standard with a blanking panel fixed over the Network bay. When a Network module is installed in this bay, network connection is made via a pair of three- pin connectors. They are wired in parallel, and form a loop-through connection. -

Page 18: Distributed/Constant Voltage Systems
Appendix E - Distributed / Constant Voltage Systems. A distributed or constant voltage system, as shown in the figure below, uses loudspeaker step-down transformers for each speaker. The transformers are designed to deliver a specific power level into a specific load impedance when a specific voltage (the example here uses 70.7 volts) appears at the pri- mary. - Page 19 Crest Audio CK Power Processing Amplifiers...
