Introduction Bogen's Black Max™ amplifiers deliver on what professional sound installers need most: Power and Reliability. Power With three different models (X600, X450, and X300), the Black Max series provides 2 independent channels of amplification at 600W, 450W, and 300W per channel into 70V constant voltage speaker loads safely and secure- ly. Located on the rear of the amplifier are the Level Controls, Low-Cut Filter Switch, and pluggable input ter- minal strip for each amplifier channel. T

Panel Descriptions Black Max Front Panel 1. Status Indicators The Status LEDs are multi-purpose indicators, one for each channel. Green - Amplifier is on and operating normally. Amber - Amplifier is in low-power consumption Sleep Mode. Red - Amplifier has protected itself due to a fault condition. 2. Signal Indicators Three illuminate green when signal is present at the output, one for each channel. 3. Limit Indicators These indicators illuminate amber when excessive signal levels or very low im

Panel Descriptions Black Max Rear Panel 1. High-Impedance Balanced Inputs Pluggable 3-position terminal strips allow for easy installation and provide convenient connections to high- impedance balanced inputs. 2. Input Level Controls Continuously variable input level controls. 3. Lo-Cut Filters Roll off frequencies below 60Hz (2nd order) to prevent saturation of speaker transformers. Flush switch actu- ators reduce tampering. 4.Automatic Sleep Mode Allows the unit to automatically put itself int

Installation Mechanical Components 1. Rack Ears Prior to installing the amplifier in to a 19" rack, you will need to attach the rack ears. Remove and save the 6 front most cover screws on each side panel of the amplifier. Position the rack ears as shown and attach using the 6 screws. 2. Dust Filter Insert the dust filter into the fan grille before attaching the fan grille to the amplifier. Filter Maintenance Dust filters are provided with the Black Max amplifier to reduce the build up of dust on

Installation Ventilation The Black Max amplifiers were designed to be placed on a table or rack-mounted. For rack-mounted applica- tions, the amplifiers can be stacked one on top of the other for maximum use of the rack space available with- out any extra, empty rack spaces between them. An open air space of at least 4" must be provided at the front air intakes of the amplifier and the rear exhaust must have at least 4" between itself and obstructions to ensure adequate cooling. This applies to

Connections Speakers 70V "Transformer-Coupled" Speakers The Black Max series was designed to drive only 70V constant volt- age type speaker loads.The use of low-impedance speakers may cause the amplifier to engage its protection circuits and shut down or limit amplifier function. The speaker terminals can accept up to a #10 AWG wire or spade lug and have integral clamping plates which make wiring easier.The polarity of each set of speaker out- puts (A & B) is indicated with a "+" and "-" sign.

Sequential Turn-On Sequential Turn-On Operation Black Max amplifiers contain a sequential turn-on feature that is designed to turn on a bank of Black Max ampli- fiers, one at a time, in sequence with approximately 1 second between each amplifier. This type of sequencing of power is necessary in large systems where the in-rush current of all the system amplifiers turning on at once would overload the AC mains supplying the system. The first amplifier in the chain will act as the master amplifier

Operation Front Controls & Indicators Power Switch The Power Switch for the Black Max amplifier is located on the front of the unit. Press the "I" side of the switch to turn the unit ON.The amplifier will begin its power up process once turned on. If the amplifi- O I er is set up for power sequencing (see the section on power sequenc- ing), the amplifier may not begin its power up process but rather wait in a standby state until it receives a sequence trigger. The Power Switch is also the amplif

Operation Sleep Switch The Black Max amplifier includes a sleep mode feature that greatly reduces the power consumption of the amplifier after it has been idle (no audio activity) for more than 3 minutes. Any audio activity present at the input will power up the amplifier instantaneously and noiseless- ly, so that there is no loss of audio.The Sleep Switch is located on the rear of the unit.The sleep feature is activated by setting the switch to the AUTO position. Setting the switch to the OFF p
