Blaze of digitally powered glory

Founded as a separate brand within Pascal A/S, Blaze Audio specialises in producing digital amplification solutions for the commercial audio market. With the creation of the first generation of PowerZone amplifiers, the Danish company has created a series of compact, configurable amplifiers for the fixed installation market.

Any output channel of the three multichannel amplifiers can be independently configured to drive both conventional low-impedance (4–16Ω – Lo-Z) and constant-voltage (70V/100V – Hi-Z) loudspeaker loads. With automatic power sharing, the PowerZone models can also share the total available power across all the channels.

Measuring half a rack in width, 1U in height and weighing 1.9kg, the PowerZone 252 amplifier outputs 2x 125W. Housed in the same chassis, the PowerZone 504 and 1004 amplifiers are 4x 125W and 4x 500W amplifiers, respectively. Simplified front control includes power and channel LEDs and channel gain adjustment knobs, whereas the rear panel interfaces mains power and GPIO connections, DIP switches and channel I/Os.

PowerZone Connect provides amplifier setup and configuration from a phone, tablet or laptop. By accessing the full matrix DSP suite embedded within the amplifier, the PowerZone Control software allows all input, output and multizone management to be configured from the smart web app.
