Crest Audio PRO SERIES 10004 Specifications

Product Description
The Crest Audio 10004 is a four-channel, high-power amplifier
designed to meet the most demanding needs of the sound profes-
sional. By providing 1400 watts at 2 ohms from each of the
amplifier's four channels, this four rack-space unit offers sub-
stantial power and versatility in a compact package.
Crest Audio's Power Density
allows the 10004 to have one of the highest power-to-weight
ratios available at any price, while maintaining superior perfor-
mance. Forced-air is employed to cool channel heat sinks mount-
ed in a back-to-back tunnel configuration. Stereo, parallel, and
bridged mono modes are chosen with two rear-panel Mode Select
switches. Actively balanced XLR input connections and 5-way
output binding post connectors are provided for each channel.
The 10004 is fully compatible in design with the other Crest
Audio Professional Series amplifiers, Octal Socket Accessories,
and the NexSys ® computer-controlled audio system.
Design and Construction
The 10004 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 10004 receives a rigorous "hot room"
burn-in before thorough final checkout on precision test equip-
ment.
The no-compromise approach in the 10004'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 ga. steel single
piece chassis.

10004 Features
• Crest Audio's legendary "overbuilt" power supply
• Toroidal power transformers
• Latest generation of high-speed, wide-bandwidth output
devices
• Tunnel cooling with back-to-front air flow

• 10004 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).
