Channels (Model)

The Monacor PA-1450D and PA-1850D Class-D PA Amplifiers are ideal for small-scale multi-zone audio systems in schools, offices, conference centres, retail stores, leisure centres and environments alike.

Each channel has a 50W output for 100V Line or low impedance loudspeakers (4 ohm). The PA-1450D and PA-1850D also provide you with a separate volume control and mute switch for each channel. This is ideal for areas that are not in use and need switching off or a situation where a room needs to be louder/quieter than the other. 

The Monacor PA-1450D and PA-1850D have an input per each channel great for installs wanting to play a different music source in each area. Alternatively, you can connect the Monacor LS-280 8-Way Splitter which will convert one audio source into 8-outs. This will enable you to play the same thing through all of the channels.

Thanks to Class-D amplification the Monacor PA-1450D and PA-1850D offer power efficiency in excess of 90% and ensures low power consumption. Not only this, the PA-1450D & PA-1850D also operate at extremely low temperatures and are protected from overheating.

The Monacor PA-1450D & PA-1850D are powered via 230V AC or 24V DC for emergency backup systems. 

These compact power amplifiers can be rack-mounted into any 19" rack cabinet or case (rack ears supplied). Alternatively, they can be used as a desktop unit. 

All Monacor products are supplied with a manufacturer's 3-Year warranty.
