Data Sheet

The amplifier shall be a Bogen Black Max Amplifier, Model
X600, X450 or X300. The amplifier shall provide two
independent channels of 70V output each with the capability
of 600, 450 or 300 watts, respectively.
The amplifier shall provide 2 separate electronically balanced
inputs available through pluggable 3-pin terminal strips. The
input impedance shall be 10k ohms in a balanced configura-
tion. Each input channel shall have a continuously adjustable
input level control mounted on the rear panel of the amplifier.
The amplifier shall have the ability to be wired to other Black
Max amplifiers in such a way as to provide power-up
sequencing of all amplifiers so wired. Sequential turn-on con-
nections shall be made through a pluggable 4-pin terminal
strip. Sequential turn-on shall be defeatable via a rear-
mounted, low-profile switch. A power status indicator on the
rear of the unit shall provide information as to the amplifierʼs
current AC power state. The indicator shall indicate either
unpowered, standby, or active state of the amplifier.
The amplifier shall have selectable input sensitivity (1V/0.1V)
and input channel link switches.
The amplifier shall drive 70V speaker loads directly without
the use of an output transformer. The amplifier shall allow
a user-defeatable low frequency roll-off at 60Hz for each
channel independently to protect transformer-coupled speakers
from saturation.
The amplifier shall have a defeatable sleep mode that greatly
reduces idle power consumption when the amplifier has not
received audio for more than 3 minutes. The amplifier shall
also include a clip limiting feature that automatically reduces
amplifier clipping.
The amplifier shall have three indicators that correspond
to status, signal, and limit.
The amplifier shall include Bogenʼs patented Back-Slope™
AC voltage regulation that automatically compensates for
surges or sags in AC line voltages of up to +/-10%.
Additionally, the amplifier shall be protected against over-cur-
rents, overloads, excessive thermal dissipation, DC voltage,
and short circuits on the outputs.
The amplifier shall be enclosed in a heavy-gauge steel
chassis with a cast aluminum front and flexible plastic fan
grilles. The amplifier shall be cooled by 2 independent fans
with continuously variable speed control and easily replace-
able fan filters.
The amplifier shall fit into a 19" rack and use two rack spaces.
It shall allow the attachment of feet for tabletop placement.
