Monacor PA-4500DX 4-Zone Multifunction Mixing Amplifier

Ultimate multi-room control with PASCAL technology: The PA-4500DX

For complex and demanding sound installations in multiple rooms, the PA-4500DX mixing amplifier offers the absolute benchmark in its class. This 4-zone powerhouse combines high efficiency with an impressive peak power of $2,000\text{ W}$. The heart of the amplifier is powered by globally acclaimed amplifier technology from PASCAL, which ensures extremely low distortion ($\text{THD} ) and crystal clear dynamics with a signal-to-noise ratio of more than $106\text{ dB}$. Whether it concerns background music in a hotel, public announcements in a business premises or dynamic audio in conference rooms; This amplifier delivers top performance under any load.

Intuitive management via HTML5 and network integration

Complicated software packages are a thing of the past. The PA-4500DX has an integrated network connection via LAN or WLAN and a built-in web server. The graphical user interface is built entirely in modern HTML5. This means that you can directly access, configure and operate the amplifier live via a standard web browser on your smartphone, tablet, Mac or PC, regardless of the operating system. The interface is clearly laid out, making routing inputs to the different zones and adjusting volumes a piece of cake.

High-End DSP processing and speaker matching

The internal DSP architecture provides audio engineers with all the tools needed for perfect acoustic tuning. The inputs are equipped with a parametric 5-band equalizer. On the output side, the amplifier has separate FIR filters (Finite Impulse Response), adjustable high-pass/low-pass filters, an accurate compressor/limiter and an adjustable delay per channel. With the built-in speaker matching (up to $10\text{ ms}$) and a switchable output phase, you ensure that all connected speakers work together perfectly in phase and time. For ease of installation, the system also features a built-in sine wave noise generator for system testing and a priority talkover function for public address microphones.

Flexible configuration and industrial reliability

Thanks to the hybrid design, the PA-4500DX supports both low-impedance systems ($4\ \Omega$or $8\ \Omega$) as well as professional $100\text{ V}$distribution lines via robust plug-in screw terminals. On the input side you have the choice between balanced screw terminals or RCA/RCA jacks for line equipment. A smart GPIO interface enables external remote volume control and standby switching, reducing standby consumption to less than $0.5\text{ W}$. The amplifier is housed in a compact 19" metal housing of only 2 HE (Rack Units) and is electronically fully protected against all conceivable operating situations, such as overheating, short circuit and overload.
