Vs1500
POWER AMPLIFIER
Product Information
The Crest Vs1500 integrates cost-effective design with exceptional sonic accuracy, long-term reliability, and basic features required for a variety of professional applications.
The Vs1500’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 compromises in component selection or quality control were permitted as a shortcut to cost reductions. In every respect, the Vs1500 embodies the Crest Audio tradition of roadworthy ruggedness and reliability. For example, the Vs1500 includes the same TourClass® protection features as found in Crest’s CA, CKS, CKV and CKX Series amplifiers. That means the Vs1500 will endure virtually any type of mishap or system stress–from uncontrolled ‘upstream’ oscillation to extreme ambient heat or accidental shorting–without damage to internal circuitry or connected speakers.
Equally suited to permanent installation or mobile applications, the Vs1500 offers a welcome balance of exceptional audio performance and overall value.
Vs1500 Features
•Robust “Over-built” Power Supply - Massive filter capacitors and a 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 Vs1500 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 performance as well as detailed, transparent high frequency response.
•Effective Cooling - Large, extruded aluminum heatsink and front-mounted, two-speed 4-inch fan minimize internal temperatures to prolong amplifier life.
•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.
•Rear Panel Detented Attenuators
•Differentially-balanced 1/4" TRS and Barrier Strip Input Connectors
•Five-Way Binding Post or Speakon Output Connectors (market dependent)
•LED Indicators for Signal Present and Clip (each channel), Active, and Protect
•Stereo/Bridged Mono Mode Select Switch
•Five Year Warranty*
