Frequently Asked Questions

What type of input connectors does the amplifier have?
The PDA-B500 features balanced audio inputs via 3-pin XLR and 6.3mm jack connectors, allowing it to be connected to a wide variety of professional audio mixing consoles and sources.

Can I use this amplifier with speakers of different impedances?
Yes, it's designed to be stable with 4 and 8 ohm loads in stereo mode. It's important to verify your speakers' impedance to ensure compatibility and optimal performance.

What does "bridged mode" mean?
Bridge mode combines the power of both channels into a single monaural output, allowing for significantly higher power delivery (500W at 8 ohms) to a single speaker. This is a very useful feature for powering high-capacity subwoofers.

Does the amplifier need additional ventilation in a rack?
The amplifier features internal temperature-controlled fans. However, as with any high-power equipment, it is recommended to leave at least one rack unit (1U) of free space above and below to ensure adequate airflow and prevent overheating.
