User manual CREST AUDIO CKV200 SPECIFICATIONS

[. . . ] Through the provision of three plug-in module bays, these amplifiers offer exceptional flexibility with integral signal processing, load monitoring, and either local or system-wide computer control via Crest Audio's NexSys® network. The CKV200 amplifier is 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. CKV200 Features · Sequential Turn-On/Off (STO). [. . . ] 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* Power Specification 20Hz - 20kHz, 0. 1% THD+N Figures are watts per channel, both channels driven. 70. 7 Volt 100W NexSys is a registered trademark of Crest Audio Inc.

A variable speed fan, with the ability to completely turn off under appropriate ambient temperature conditions, shall provide air flow through the chassis from front to both sides. The amplifier shall have circuitry to protect itself and the speaker load from output short circuits, DC voltage on outputs, and thermal overload. The amplifier shall include circuitry to gradually increase gain to attenuator setting levels when amplifier is turned on, and circuitry for impedance sensing and active clip limiting. The amplifier shall include an energy saving feature which shall automatically remove the output stage bias current when the amplifier is in an idle condition. The amplifier shall have a voltage gain of X40, or a voltage gain of X20, or an input sensitivity of 0. 775V, for rated power, internally jumper-selectable. The hum and noise level shall be greater than 105dB below rated output, "A" weighted. The amplifier shall have a class AB output stage (with a modulated power supply). The frequency response shall be greater than 20Hz-20kHz, +0, -0. 3dB at rated power. The amplifier shall operate at either 100, 120, 220, 230, or 240 volts, 50-60 Hz AC (configured at factory). Maximum current draw at 120V shall be no greater than 4. 2A, both channels driven continuously into a 70. 7V line. Front panel LED indicators shall include Active, Protect, Signal Present, and ACL (Clip Limiting) LEDs for each channel. The power switch shall have three positions; one to permit power up from a remote location, one to permit local power up, and an "off" position. The fan filter shall be front panel mounted, with no tools required for removal. The rear panel shall be configured with three openings or bays which will accept plug-in modules used to accomplish input signal processing, network control, remote sequential turn-on/off and other related functions. The output module shall be fitted with the following connectors: 5mm, 4-pin Phoenix for sequential turn-on/off wiring, and an output barrier strip with 0. 438" (11mm) screw spacing, and 0. 320" (8mm) lug space. The input module shall be fitted with an input barrier strip connector with 0. 320" (8mm) screw spacing, and 0. 270" (7mm) lug space, and two individual channel attenuators with removable knobs.
