• Sequential Turn-On/Off (STO). Standard system uses any +8 to
+18VDC source and contact closure.
• PowerSave. Reduces power consumption at idle by turning off the
bias circuit (and fan if heat sink temperature is below allowed thresh-
old) when no signal present at input.
• 3 Module Bays. Unique chassis construction provides three separate
bays into which a diverse range of space-saving and cost effective
Input Processing, Network and Power/Output modules can be fitted.
By combining multiple processing and control functions in the ampli-
fier, CKV Series Power Processing amplifiers significantly save on
installation costs versus conventional outboard processing.
• Cool Operation. High thermal mass heat sinks, with high-efficiency
variable speed fan. Front panel mounted filter for easy maintenance.
• “Overbuilt” Power Supply. In the Crest tradition, the CKV power
supply is “over-engineered” for ample current reserves to meet
demanding load conditions.
• More Transistors. More output devices than comparably-powered
competitive models to provide wider safe operating area and lower
heat generation.
Product Description
The Crest Audio CKV2400 Power Processing amplifier is designed specifically for the unique requirements of high quality, 70V distributed sound
systems in commercial, industrial and institutional installations. Design goals met by the CKV2400 include exceptional sonic accuracy, high effi-
ciency, minimum power consumption, comprehensive loudspeaker protection, and the ability to handle extended duty cycles.
In addition, the CKV2400 incorporates Crest Audio’s proprietary modular approach to input/output and external control configuration. We call this
concept Power Processing. Through the provision of three plug-in module bays, these amplifiers offer exceptional flexibility with integral signal pro-
cessing, load monitoring, and either local or system-wide computer control via Crest Audio’s NexSys
®
network.
The CKV2400 amplifier is are manufactured exclusively in Crest Audio’s own USA plant, using only the highest quality components.
Key sub-assemblies are individually pre-tested, and all units are rigorously “burned-in” before final checkout on precision test equipment.

Protection Circuits:
ACL (Active Clip Limiting) prevents speaker damage with gentle
gain reduction at clip threshold.
IGM (Instantaneous Gain Modulation) monitors connected loads to
detect conditions that may overstress output devices, allowing safe
operation into difficult loads.
AutoRamp gradually increases gain to attenuator setting level when
amplifier is turned on.
TourClass also includes comprehensive thermal management, and
short circuit, DC voltage, turn-on/off transient, current inrush and
sub/ultrasonic input protection.
• Selectable input sensitivity/voltage gain (internal jumpers)
• UL certification
• Front panel status indication
• Rear panel attenuators with removable knobs
• Barrier strip input and output connectors
• Optional input isolation transformers
• Front panel label area
• Full five-year warranty*
