Product Description
The Crest Audio 10001 is an extremely high-power amplifier
designed to meet the most stringent needs of professional use in
concert touring, high quality sound reinforcement, and profes-
sional fixed installations.
Crest Audio’s Power Density
™
engineering philosophy allows the
10001 to have one of the highest power-to-weight ratios available
at any price, while maintaining superior performance. The 10001
is fully compatible in design with the other Crest Audio
Professional Series amplifiers, Crest Audio’s Octal Socket
Accessories, and the NexSys
®
computer-controlled audio system.
A four rack-space amplifier, the 10001 uses forced-air to cool
channel heat sinks mounted in a back-to-back tunnel configura-
tion. Stereo, parallel, and bridged mono modes are chosen with a
rear-panel Mode Select switch. Actively balanced XLR input
connections and solderless output connectors are provided for
each channel.
Design and Construction
The 10001 is built exclusively in Crest Audio’s own USA manu-
facturing facility, with internal components selected for premium
quality and proven durability. Each modular subassembly is pre-
tested, and the assembled 10001 receives a rigorous “hot room”
burn-in before thorough final checkout on precision test equip-
ment.
The no-compromise approach in the 10001’s electrical design
and mechanical construction provides the ultimate in reliability
and performance. Only high-grade components are used for the
modular sub-assemblies in this ultra-strong, 12 gauge steel single
piece chassis.
10001 Features
• Crest Audio’s legendary “overbuilt” power supply
• Toroidal power transformer
• Latest generation of high-speed, wide-bandwidth output
devices
• Tunnel cooling with back-to-front air flow
• Variable speed DC fan
• High thermal mass heat sinks
• Balanced XLR inputs
• Single screw solderless output connectors
• Stereo/Parallel/Bridged Mono mode selector switch
• Rear panel ground lift jumper
• 10001 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.
• Recessed, stepped attenuators
• Front panel circuit breaker/power switches
• Modular construction
• Full five-year warranty
(USA, Canada, U.K. & many other countries).
