Power Dynamics PDC90 - Professional Multimedia Player and Mixer Amplifier

The Power Dynamics PDC90 is an all-in-one audio solution designed for commercial installations and public address systems that require versatility, reliability, and complete control. This multifunctional unit combines a powerful Class D stereo amplifier, a multi-source mixer, and an advanced media player in a compact 1U chassis, perfect for mounting in standard 19-inch racks. Its intelligent design and robust construction make it the ideal core for any professional sound system.

With an RMS output of 60W, the PDC90's Class D amplifier ensures efficient, clear, and low-distortion audio playback, capable of driving low-impedance speakers (minimum 4 ohms). Versatility is its strong point, offering a wide range of built-in playback sources. Tune in to digital radio stations with the highest quality and without interference thanks to its DAB+ tuner. Play your music library directly from a USB drive via the front port, or wirelessly stream audio from any smartphone, tablet, or computer with its Bluetooth 5.0 receiver, which ensures a stable and long-range connection.

The PDC90's connectivity is exceptionally comprehensive to suit any environment. It features three balanced XLR mic/line inputs, each with individual DIP switches to activate +48V phantom power (for condenser microphones) and to select the signal level (mic or line). Channel 1 has an adjustable VOX priority function, which automatically attenuates other audio sources when it detects a signal at the microphone—ideal for announcements and messages. It also includes two stereo RCA line inputs and a front-panel 3.5mm auxiliary input for easy connection of external sources. On the output panel, you'll find a balanced stereo mix output (XLR), a preamp output (RCA), and screw terminals for direct speaker connection.

Frequently Asked Questions

What type of speakers can I connect and how many?
The PDC90 delivers a total power of 60W RMS in stereo. It is designed for low-impedance speakers, supporting a minimum load of 4 ohms per channel. This allows you to connect, for example, one 4-ohm speaker per channel, or two 8-ohm speakers in parallel per channel.

Does phantom power activate for all microphone inputs at the same time?
No. Each of the three XLR inputs has its own independent DIP switch on the rear panel to enable or disable +48V phantom power. This gives you the flexibility to use condenser and dynamic microphones simultaneously.

Can I connect the PDC90 to a larger external power amplifier?
Yes. You can use the RCA preamp output (REC Output) or the balanced XLR mix output (Mix Output) to send the audio signal to an external power amplifier and drive a larger speaker system.

Which version of Bluetooth does it use?
It uses Bluetooth version 5.0, which provides a more stable wireless connection, greater range, and better audio quality compared to previous versions.

What is the purpose of the 24V DC Mute input?
This input is designed to integrate the equipment with alarm or emergency systems. Upon receiving a 24V signal (from, for example, a fire alarm panel), the amplifier will automatically mute all audio sources.
