Rane MA 3 Amplifier

• 3 independent channels @ 40 W RMS into 8 ohms, 20-20k Hz
• Load sensitive dynamic limiters and headroom meters; Input level controls (on rear); 80 Hz high pass filter selection
• Up to 3 optional internal 70.7 V or 100 V distribution transformers
• Balanced Euroblock inputs; Euroblock speaker connectors handle up to 12 gauge wire

The MA 3 was specifically designed for use in:

• Paging
• Foreground Music
• Background Music Distribution.

Each channel of the MA 3 delivers 40 watts of continuous average power into 8 ohms and 60 watts into 4 ohms. Up to three optional 40 watt, 70.7 volt or 100 volt constant-voltage audio transformers may be installed inside the MA 3, eliminating the need for external wiring or transformer mounting.

The MA 3 uses a conventional linear power supply with toroidal transformer. This configuration minimizes the emissions associated with switching supplies and noisier transformer designs. Thermal management is accomplished with a sealed heat-tunnel design incorporating low velocity forced air and large aperture openings. Forced air cooling allows the amplifier to operate reliably in harsh environments and avoid the buildup of heat in unventilated racks associated with passive convection cooling.
