The AX3800 from AMPERES is an 8 duty / 1 standby auto changeover unit that provides a switching platform for the standby unit to replace the position of a failed duty amplifier. This public address system supports switching at both the input and output sections, making it ideal for matrix systems with multiple amplifiers with different input sources. The detection frequency is 20 KHz, which is inaudible to human ears.
While it is compatible with most amplifier brands, please check the amplifier specifications as they may have a high frequency cut off, which would make the overall changeover functions unstable.
