PRODUCT DESCRIPTION
THE CREST AUDIO 7001 POWER AMPLIFIER IS A COMPACT, HIGH-POWER
AMPLIFIER DESIGNED TO MEET THE STRINGENT NEEDS OF PROFESSIONAL USE
IN CONCERT TOURING, HIGH QUALITY SOUND REINFORCEMENT, PROFESSIONAL
FIXED INSTALLATIONS, AND STUDIO MONITORING.
A TWO RACK-SPACE AMPLIFIER, THE 7001 USES FORCED-AIR TO COOL
CHANNEL HEAT SINKS MOUNTED IN A BACK-TO-BACK TUNNEL CONFIGURA-
TION. STEREO, PARALLEL, AND BRIDGED MONO OPERATING MODES CAN BE
CHOSEN WITH A REAR-PANEL MODE SELECT SWITCH. AN ACTIVELY BAL-
ANCED FEMALE XLR INPUT CONNECTION AND 5-WAY OUTPUT BINDING
POSTS ARE PROVIDED FOR EACH CHANNEL.
THE 7001 IS FULLY COMPATIBLE WITH THE OTHER CREST AUDIO
PROFESSIONAL SERIES AMPLIFIERS, OCTAL SOCKET ACCESSORIES AND THE
NEXSYS®COMPUTER-CONTROLLED AUDIO SYSTEM.
DESIGN AND CONSTRUCTION
THE NO-COMPROMISE APPROACH IN THE 7001’S ELECTRICAL DESIGN AND
MECHANICAL CONSTRUCTION PROVIDES THE ULTIMATE IN RELIABILITY AND
PERFORMANCE. ONLY HIGH-GRADE COMPONENTS ARE USED FOR THE MOD-
ULAR SUB-ASSEMBLIES IN THIS ULTRA-STRONG, SINGLE PIECE STEEL CHASSIS.
7001 FEATURES
• NEXSYS-READY
• TOROIDAL POWER TRANSFORMER
• TUNNEL COOLING
• DUAL, VARIABLE SPEED DC FANS
• 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 2ΩIMPED-
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.
