Product description

• 300W per channel at 70V with independent low-cut filters on each input

• Low noise and distortion with high slew rate

• Highly efficient Class-H amplification driven by a conservatively rated toroidal power transformer

• Transformerless direct drive outputs

• Electronically balanced high-impedance inputs

• Large output heat sinks and dual independently controlled, high-output, variable-speed cooling fans provide reliable cooling and quiet operation while reducing dust accumulation

• Internal electronic components are located outside of the forced air stream flow to ensure minimal required maintenance and cleaning

• Front-mounted fan filters are easily removed for cleaning

• Multiple electronic protections including overcurrent, DC voltage, and thermal circuits

• 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 regulates the AC energy supplied from the power toroid to improve system performance and reliability despite varying AC supply conditions

• Defeatable energy-conserving sleep mode with instant-on return signal operation reduces wasted heat production in paging systems with intermittent use

• Pluggable terminal strip for sequencing wiring in multi-amp installations

• 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 one second of delay between units

• Directly stackable, mounts in two rack spaces without need for extra space above or below
