Product Information
The Crest V650 integrates cost-effective design with exceptional
sonic accuracy, long-term reliability, and basic features required
for a variety of professional applications. Attractive, high-tech
styling and comprehensive metering make the V650 an excellent
choice.
The V650’s remarkable price/performance ratio is the result of
innovative engineering and highly efficient manufacturing in
Crest’s modern USA facility–along with nearly two decades of
leadership in professional amplifier design. However, no com-
promises in component selection or quality control were permit-
ted as a shortcut to cost reductions. In every respect, the V650
embodies the Crest Audio tradition of roadworthy ruggedness
and reliability. For example, the V650 includes the same
TourClass
®
protection features as found in Crest’s CA, CKS,
CKV and CKX Series amplifiers. That means the V650 will
endure virtually any type of mishap or system stress–from uncon-
trolled “upstream” oscillation to extreme ambient heat or acci-
dental shorting–without damage to internal circuitry or connected
speakers.
Equally suited to permanent installation or mobile applications,
the V650 offers a welcome balance of exceptional audio perfor-
mance and overall value.
V650 Features
• Robust “Over-built” Power Supply - Massive filter capacitors
and high output custom transformer provide ample current for
solid bass performance, even when driving low impedance loads.
• More Output Transistors - By using more output devices than
many comparable competitive models, the V650 puts less stress
on each device for a wider safe operating area (SOA) and long-
term reliability.
• Wide-Band Design - Frequency response extends from 10Hz
to 20kHz (-3dB at 165kHz), ensuring powerful sub-bass perfor-
mance as well as detailed, transparent high frequency response.
• Effective Cooling - Large, extruded aluminum heatsink and
front-mounted, two-speed 4-inch fan minimize internal tempera-
tures to prolong amplifier life.
• 20-Segment Precision Meter Display - Instantaneous metering
with peak hold and ACL operation readings.
• Rated for Sustained Operation into 2Ω Loads
• Front Panel Magnetic Circuit Breaker/Power Switch -
Eliminates need for AC line fuses.
• TourClass 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 nominal 2Ω impedances.
AutoRamp gradually increases gain to attenuator setting
level when the amplifier is turned on.
TourClass also includes protection from thermal runaway,
input overload, DC, short circuit, in-rush current, and turn-
on/turn-off transients.
• Recessed Front Panel Detented Attenuators
• Differentially-balanced 1/4" TRS and Barrier Strip Input
Connectors
• Five-Way Binding Post or Speakon Output Connectors
(market dependent)
• Additional LED Indicators for Active and Protect
• Stereo/Bridged Mono Mode Select Switch
• Five Year Warranty*
