The amplifier shall be a Bogen Black Max Amplifier, Model
X600, X450 or X300.The amplifier shall provide two indepen-
dent 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 configuration.
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 sequenc-
ing of all amplifiers so wired. Sequential turn-on connections
shall be made through a 4-pin pluggable 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 amplifier’s current AC
power state. The indicator shall indicate either unpowered,
standby, or active state of the amplifier.
The amplifier shall drive the 70V speaker loads directly with-
out the use of an output transformer.The amplifier shall allow
a user-defeatable low frequency roll-off at 60Hz for each chan-
nel 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 ampli-
fier clipping.
The amplifier shall have three indicators that correspond to
status, signal, and limit.
The amplifier shall include Bogen’s 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-currents, 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 continu-
ously variable speed control and easily replaceable 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.
