[. . . ] Declaration of Conformity Application of Council Directive: 73/23/EEC (low voltage directive) Application of Council Directive: 89/336/EEC (EMC Directive) Standard(s) to which Conformity is Declared: EN55103 -1 (Emissions) EN55103 -2 (Immunity) EN60065 Manufacturer's Name: Hafler (Safety) Manufacturer's Address: 546 South Rockford Drive, Tempe, Arizona 85281 Importer's Name: Importer's Address: Type of Equipment: 2-channel Audio Power Amplifier Model No. : Serial Number: Year of Manufacturing: 2000 2001 2002 2003 2004 GX2800CE I, the undersigned, hereby declare that the equipment specified above conforms to the above Directive(s) and Standard(s) Place: Hafler Date: 5/1/2000 James C. Strickland, VP Engineering Table of Contents DECLARATION OF CONFORMITY . . 8 What else distinguishes these amplifiers?. 20 SERVICE POLICY AND LIMITED WARRANTY . [. . . ] Status LEDs - Displays the status of the amplifier. The LEDs are as follows: SIGNAL indicates if signal is present; CLIP illuminates if the amplifier is being overdriven; PROTECT illuminates if the amplifier is experiencing a "short" in the speaker array; THERMAL illuminates if the amplifier has shut down due an overheating condition. Female XLR & 1/4" TRS Input Jacks - Feeds input signal to the amplifier using industry standard male XLR or 1/4" TRS (tip/ring/sleeve) plugs. Crossover/Delay/CD Eq/Phase - Each channel has an independendently configurable 500/800Hz, Low Pass/High Pass Crossover; 0-30" Time Delay; 0 to +10dB CD Horn Equalizer; 0/180 degree Phase switch. Stereo/Mono Switch - This dual purpose switch is used to select the operating mode of the amplifier. In Stereo mode the amplifier can be configured for standard 2-channel stereo operation. In Mono mode the amplifier can be configured for Standard Bridge mono, 70V mono or 100V mono operation. Turn amplifier off before operating this switch. Level Controls - Adjusts the gain of the amplifier. Load Switch - Selects the speaker impedance or transformer voltage that will be connected the output binding posts. In Standard Mode the amplifier can drive 2, 4 or 8 speaker loads. In Constant Voltage Mode the amplifier can drive an array of speakers using 70V or 100V transformers. Output Binding Posts - Connects the speaker array to the amplifier. These jacks allow bare wire, spade lugs or dual banana plugs to be connected to the amplifier. 11. Internal Fans - internal fans keep the amplifier circuitry cool. Allow a minimum of 3" clearance on the front and back of the amplifier vents for adequate ventilation. Chassis/Float ground switch - Isolates Audio Ground from Chassis Ground (Chassis Ground is permanently connected to Earth Ground through the third pin of the power cord). With the switch in the "Chassis" position, the Audio Ground is connected to Chassis Ground. In the "Float" position, Audio Ground is isolated ("floated") from Chassis Ground, and must be connected to Earth Ground by other means. ! CAUTION: Do not attempt to "float" Audio Ground from Chassis Ground unless you are absolutely certain there is some other common ground between the amplifier and the source equipment. Without this common ground, oscillations and severe damage may occur. 13. Mains Power Fuse - Protects the "mains" electrical circuit in case abnormal current draw from the amplifier is experienced. Mains Power Connector - Connects AC Voltage to the amplifier. [. . . ] Amplifier will clip at 70Vrms level. ­ 19 ­ 100V MONO MODE CE SPEAKON Connector Wiring Connect to CH A output 1. Connect signal from source to CH B input. Biamp/Stereo switch not active (Stereo/Mono switch overrides this switch when in mono/70V/100V mode). Connect parallel array of 100V transformer-equipped speakers across the red terminals of the 5-way binding posts. [. . . ]
