Page 5: General Information
FZ10004 • Make sure that the signal is correctly connected to the amplifier’s input channel and set to the proper input mode. • Please turn off the power switch before pulling off the power cord. • At the beginning, please always set the volume at the -80dB position. -
Page 6: Introduction
- 1 - INTRODUCTION 1.1 DESCRIPTION AND TECHNICAL SPECIFICATIONS FZ10004 is a 4ch amplifier capable to deliver 4x2500W @2Ohm and 4x2100W @4Ohm, in 2U rack mount only. These features make it ideal for professional full-range speakers and in multi-amplified system character- ized by wide dynamics and high performance. - Page 7 FZ10004 • CPL , (Current Peak Limiter) ensures that the amplifier’s Output does not exceed the safe current han- dling parameters of amplifier components. • Temperature protection ensures that the amplifier will not be damaged by exceeding thermal limits. • VHF , (Very High Frequency) protection circuits mute the output of the amplifier when non dynamic continuous signals above 10 KHz are detected.

Page 8: Front Panel Overview
FZ10004 1.3 FRONT-PANEL OVERVIEW The amplifier’s front panel presents the performance and fault condition indicators, power and remote switches, and a removable dust-filter cover. Level potentiometers provide individual attenuation for the amplifier channels. Range is 0dB to - infinity. (The 12 o’clock position indicates -10dB attenuation.) A con- venient label strip with writing surface is provided adjacent to each level potentiometer. -

FZ10004 - 2 - INSTALLATION 2.1 UNPACKING Carefully open the shipping carton and check for any noticeable damage. The power amplifier is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discov- ered, please notify the shipping company immediately. -
Page 13: Cooling
FZ10004 2.3 COOLING The amplifier uses a forced-air cooling system with air flow from front to rear, maintaining a low operating temperature within defined limits. Front-to-rear airflow is preferred as cooler air is present at the front in nearly all applications. (This allows higher continuous power levels without encountering thermal prob- lems). -

FZ10004 - 3 - FUNCTIONS AND SETTINGS 3.1 INTRODUCTION The following sections provide comprehensive information on amplifier connection, setup, operation, and performance. The detailed information included here is essential to realizing the full functionality of the amplifiers. 3.2 OPERATION PRECAUTIONS • Make sure that the Power switch on the amplifier front panel are set to off before making any input,... - Page 16 FZ10004 Headroom, sensitivity and VL/Gain settings The input amplifier and limiter system is designed to accommodate extremes of performance. Typically, exceeding maximum input by much as +10dB will only result in a 1% increase in distortion. The following schematics illustrate how the adjustable VL and Gain circuitry affect input sensitivity and output power.

FZ10004 3.4 AUDIO INPUT AND OUTPUT CONNECTIONS Balanced Input connections The XLR input connectors are electronically balanced, and wired according to the IEC 268 standard (pin 2 = hot). XLR input connectors should be wired as follows: Pin 1 Ground/Shield Pin 2 Hot (+) Pin 3 Cold (-). - Page 18 FZ10004 Speakon Output connections Amplifier is equipped with the Speakon output connectors. Speakon outputs - four-channel models CH 4 CH 3 CH 2 CH 1 Fig.13 Four -channel amplifiers are wired in the following manner. The right Speakon connector, Channel A+B, provides outputs for both Channel A and Channel B.
- Page 19 FZ10004 Output bridge mode When bridged, the input source must be connected to input A (A+B) or C (C+D) respectively. Output speakon cables must be connected to the bridge on channel 1+/2+ of channel 1 and 3+/4.+ of channel 4. The main benefit of bridging the output is a doubling of output voltage. Bridging can be...
- Page 20 FZ10004 V peak (VL) V rms Output Current Peak Limiter (CPL) The Current Peak Limiter (CPL) ensures that the amplifier will not be damaged by forcing the amplifier to deliver current levels to the outputs that exceed the physical limits of the transistors. The CPL keeps the amplifier within the Safe Operating Area (SOA.)

FZ10004 3.5 PROTECTION, FAULTS AND WARNINGS Introduction The amplifier incorporate a sophisticated and comprehensive set of protection features. Faults and warn- ings are indicated on the front panel and reported. Safe Operating Area detector (SOAD) The Safe Operating Area Detector (SOAD) compares output voltage against output current to ensure that the output transistors are working inside their safe operating area. - Page 22 FZ10004 Safe Operating Area detector (SOAD) The Safe Operating Area Detector (SOAD) compares output voltage against output current to ensure that the output transistors are working inside their safe operating area. The SOAD provides fault monitoring and input to the Current Peak Limiter (CPL). The SOAD has no dedi- cated indicator, and its operation is revealed only in conjunction with features such as the CPL.
