The PowerZone Connect 504 is a compact DSP amplifier in a half rack, 1U format. It’s network-connected, giving wired or wireless access to the PowerZone Control web app’s system setup and audio configuration menu. From here you can manage inputs/outputs, control sound zones and access professional tuning settings – all helping achieve impressive sound in the shortest time possible.

It can drive both conventional low impedance (4O to 16O) loudspeakers and constant voltage (70V/100V) transformer coupled loudspeakers. With four analogue inputs, and one stereo digital input, it has flexible output options – 4 x 125W in Lo-Z mode and 2 x 250W in Hi-Z mode. Automatic power sharing technology enables 250W to be shared proportionately between each pair of Lo-Z outputs. 

• Full matrix DSP amplifier with configuration and control via the simple WebApp
• Flexible power output with 4 x 125W / 2 x 250W and power sharing technology
• Route any input to any output channel – create sound Zones in minutes
• Ultra-compact form factor means it can be installed in spaces where others cannot
• Powered by Pascal UMAC™ Class-D technology
