A surge protector or battery backup should be fine. A power conditioner, on the other hand, can be problematic if it is not capable of handling the Max power draw of the gear connected to it. Devices with amps are the usual problem since their Max draw can be much higher than their average draw.I remember someone at some point saying you shouldn’t use a surge protector or was it a power conditioner with anthem products. Is it ok to use a surge protector or power conditioner or surge suppressor with anthem products?
