Know before you buy
The Push Here Diagnostic (PHD) system performs an automated test of the connected speakers and wiring. It identifies potential issues like short circuits or open loads, which significantly simplifies troubleshooting and routine maintenance for your audio installation.
Yes, the AA50PHD is highly versatile and supports 25V, 70.7V, and 4-ohm loads. This allows you to use it for both distributed commercial audio systems and standard low-impedance speaker setups.
Yes, the balanced Mic/Line/Tel input includes phantom power, allowing you to connect and power condenser microphones directly without needing an external power supply.
The Zone 2 output is assignable, allowing you to route specific audio signals to a secondary area or an external amplifier. This is useful for environments where you need independent control over audio in a separate room or zone.
Yes, the unit features rear-mounted DIP switches that allow you to configure input muting and sensitivity. This gives you granular control over how different audio sources interact, such as prioritizing a microphone signal over background music.
Absolutely. The unit includes a dedicated preamp input, which allows you to integrate external processors like equalizers or feedback suppressors into your signal chain before the power amplification stage.
