Suitable for all two or four-horn applications our Standard Amplifier now provides 200 Watts RMS per channel (8 ohms for a pair of horns per channel), 400 Watts RMS in bridged mode (4 ohms for four horns) or 350 Watts in 70V mode. The amplifier automatically powers down after several minutes of inactivity. Both LX and AX carillons provide an imperceptible signal to wake the amplifier before ringing.

The Standard Amplifier is included in the Community Outreach audio package for electronic carillons.
