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 configuring and operating multi-zone audio systems for hotels, sports venues, houses of worship, schools, retail spaces, restaurants, meeting spaces, and conference facilities.
This advanced multi-input audio mixer amplifier features matrix technology, allowing you to route up to five separate inputs to four distinct zones. Ideal for multi-zone paging, background music distribution, and room-combining applications, each input also features independent bass, treble, and volume controls for precise audio adjustment in every zone.
The RZMA240BT is equipped with zone-selectable inputs, allowing any input to be assigned to any output. Simply press a button to route your inputs to the desired outputs with no programming or tuning required. Every zone supports either 70V/100V high-impedance or 4-ohm low-impedance speaker connections, allowing mixed impedance configurations throughout the system.
Advanced matrix technology allows four zone-selectable inputs to be assigned to a single zone or multiple zones with the push of a button. Analog routing eliminates the need for programming, making it easy to configure outputs directly from the front panel.
The rear panel includes three XLR/TRS combo inputs with selectable MIC or LINE levels, dual RCA inputs with variable gain control, a telephone paging input with variable gain control, and a remote microphone input via network category cabling.
Each zone can be independently configured for 4-ohm, 70V, or 100V speaker systems. With matrix-selectable inputs and outputs, the RZMA240BT provides a highly integrated four-zone audio solution for hotels, shopping malls, sports facilities, entertainment venues, and other commercial installations.
A built-in monitor amplifier provides a 1 watt/8-ohm output for control room monitoring. Operators can monitor any combination of zone outputs with independent level control.
Balanced 1-volt, 600-ohm line-level outputs are available for each zone, making it easy to connect additional amplifiers, recording equipment, or other audio devices.
An RS232 serial control port command set is available upon request.
Due to the possibility of FM radio interference and the variables involved, FM radio is not recommended as the primary input source.
