DETAILS

The Monacor STA-450D & STA-850D Digital PA Power Amplifiers are perfect for multi-zone PA applications for both music playback and voice. Available with 4 or 8 channels.

These digital power amplifiers are equipped with 4 or 8 channels all rated at 50W RMS. For a higher output power, two channels each can be bridged providing a combined 100W RMS output. Each channel has its own level control.

Thanks to Class-D Amplification the STA-450D & STA-850D are extremely energy efficient and operate at really low temperatures. They also have a silent operation due to a fanless cooling concept. 

Inputs include 4 or 8 x XLR sockets designed for balanced signals from mixing desks, Preamplifiers and CD players (550 mV min.) and 4 or 8 x RCA jacks for connecting a standard signal source from smartphones, tablets, and laptops (1 V min.).

Installation is quick and easy and will have you up and running in no time. Loudspeakers can be connected to the STA-450D and STA-850D via the push terminals at the rear of the amplifier. 

The Monacor STA-450D and STA-850D PA Amplifiers are designed for installation into a 19" rack cabinet (482mm), but can also be used as a tabletop unit. The STA-450D and STA-850D take up 2U rack space. 

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