Crest Audio PRO SERIES 6001 Specifications

POWER AMPLIFIER
Product Description
The Crest Audio Model 6001 is a compact, high-power ampli-
fiers designed to meet the most stringent demands of professional
use in concert touring, studio monitoring, high-quality sound
reinforcement, and professional installations.
A forced-air configuration is used to cool channel heat sinks
mounted in a back-to-back tunnel arrangement. An actively bal-
anced female XLR input connection, Octal Socket, and 5-way
output binding posts are provided for each channel.
The 6001 is fully compatible in design with other Crest Audio
Professional Series amplifiers, Octal Socket Accessories, and the
NexSys ® computer-controlled audio system.
Design and Construction
Crest Audio's no-compromise approach in the 6001's electrical
design and mechanical construction adds up to the ultimate in
reliability and performance. Only high-grade components are
used for the modular sub-assemblies in their ultra-strong, single
piece steel chassis.

6001 Features
• NexSys-ready
• Toroidal power transformer
• Tunnel cooling
• Variable speed DC fan
• High thermal mass heat sinks
• Balanced XLR inputs
• 5-way output binding post connectors
• Stereo/Parallel/Bridged Mono mode selector switch
• Rear panel ground lift jumper
• Extensive protection circuitry:
- 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 imped-
ances.
- AutoRamp gradually increases gain to attenuator setting
level when amplifier is turned on.
- Other protection circuitry: comprehensive thermal manage-
ment, and short circuit, DC voltage, turn-on/off transient,
current inrush and sub/ultrasonic input protection.
• Ultra-strong, single piece steel chassis
• Octal Accessory sockets
• Recessed, stepped attenuators
• Front panel circuit breaker/power switch
• Modular construction
• Five-year warranty
(USA, Canada, U.K. & many other countries).
