Important Safety Information

WARNING: To Reduce The Risk of Fire Or Electric Shock,

Do Not Expose This Apparatus To Rain Or Moisture.

Always follow these basic safety precautions when installing and
using the unit:

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. DO NOT block any ventilation openings. Install in accor­dance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers)
that produce heat.

9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding-type plug has two
blades and a third grounding prong.The wide blade, or the
third prong,are provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufac­turer.

12. Unplug this apparatus during lightning storms or when
unused for long periods of time.

13. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.

CAUTION: TO PREVENT THE RISK OF ELEC­TRIC SHOCK, DO NOT REMOVE COVER (OR
BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
PERSONNEL.

The lightning flash with arrow­head symbol, within an equilat­eral triangle, is intended to alert
the user to the presence of
uninsulated “dangerous voltage”

that may be of sufficient magni­tude to constitute a risk of elec­tric shock to persons.

The exclamation point within an

to alert the user to the presence
of important operating and
maintenance (servicing) instruc­tions in the literature accompa­nying the appliance.

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 secure­ly. Located on the rear of the amplifier are the Level Controls, Low-Cut Filter Switch, and pluggable input ter­minal strip for each amplifier channel. These amplifiers are powerful (with total system power of 1200W,900W
and 600W with both channels driven), but they are also compact - using up only 2 rack spaces (3-1/2") in a
standard 19" rack.

Reliability and Functionality

Driven by a conservatively-rated toroidal power transformer, these amplifiers are built for solid performance
with low distortion and a high slew rate.The amplifiers require little maintenance and cleaning as internal elec­tronic components are located outside of the forced air stream flow. Front-mounted fan filters provide easy
removal and cleaning.

Black Max amplifiers have a variety of electronic protection circuits including overcurrent,DC voltage, and ther­mal circuits. A special Clip/Limiting circuit continuously monitors the amount of distortion in the output signal
and reduces input levels as the amplifier approaches clipping. Back-Slope™ AC Voltage Stabilization, Bogen’s
unique voltage stabilization circuitry, regulates the AC energy supplied from the power toroid. This improves
both system performance and reliability despite varying AC supply conditions.

An energy-conserving sleep mode (defeatable) with instant-on return signal operation reduces wasted heat
production in paging systems with intermittent use. In addition, large output heatsinks and dual independently­controlled, high-output, variable speed fans provide superior cooling and quiet operation while reducing dust
accumulation.

A simple and reliable sequential turn-on feature minimizes in-rush current from the AC power mains.When
multiple Black Max amplifiers are daisy-chained together for sequential turn-on, the first amplifier in the series
will control the powering up of the other amplifiers with approximately 1 second of delay between units.
Turning off the first amplifier causes all amplifiers to turn off.

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 impedance output loads cause out­put distortion to exceed a few percent Under such conditions, a built-in Clip/Limiting circuit activates and
reduces input signal levels to protect both amplifier and speaker loads. One for each channel.

4. Power Switch/Circuit Breaker

Magnetic circuit breaker controls AC power to the amplifier.

5. Fan Air Intake and Grilles

Air intakes for 2 independent, variable speed cooling fans. Each responds as needed to keep the amplifier cool
while reducing dust build-up. Removable fan grilles are provided to allow access to the dust filters for cleaning.
