Pure Resonance Audio DA2240 Dual-Impedance 240W Rack Mount Power Amplifier
Usually arrives in 5-9 business days.
Designed as an all-in-one solution for conÞguring and operating multi-zone audio systems for hotels, sports venues, and houses of worship, schools, retail spaces, restaurants, meeting and conference spaces.
This advanced multi-input audio mixer amplifier features matrix technology, letting you route up to 5 separate inputs to 4 distinct zones. Ideal for multi-zone paging, music distribution, and room-combining applications, each input is also supplied with separate bass, treble and volume control for precise sound in each individual zone.
The RZMA240BT is equipped with zone-selectable inputs, meaning that an input can be assigned to any output. You simply push a button to route your inputs to the appropriate outputs, no programming or tuning required. You can also mix 70V and 8 ohms between zones with high impedance and low impedance supported with every zone.

Advanced matrix technology allows four zone selectable inputs to be assigned to a zone, or across multiple zones with the push of a button. Analog routing via button assignments means that no programming is needed. You can easily route outputs through the button selections on each input on the front of the mixer amplifier.
The rear inputs on the RZMA240BT include 3 XLR/TRS combo jacks with MIC or LINE level switching, dual RCA inputs with variable gain control, telephone phone input with variable gain control, and remote mic input via network category cabling.
High or low impedance outputs at 4 ohms, 70V, and 100V are configurable by zone. The inputs and outputs can be matrix selected, thus it is a highly integrated 4 channel audio matrix system solution with MP3 player for hotels, shopping malls, sports centers, entertainment centers, etc.

A monitor is built-in for in-room monitoring use with 1 watt/8 ohm output for zone monitoring. The control room can monitor any combinations of zone outputs and has its own level.

Balanced 1-volt line level outputs at 600Ω are available for every zone.
An RS232 serial control port command set is available upon request.
Due to the possibilities of FM radio interference and the variables involved, it's not recommended to use FM radio as your primary input source.
