1. Why do Emotiva amplifier power cords not have a ground?
A grounded power cord can create a 'ground loop' in your system, which creates noise. Our amps are specifically designed to prevent ground loops, and have multiple layers of grounding and shielding internally. They meet all CE regulations (worldwide safety regulations).

2. Should I use a power conditioner or surge protector with an Emotiva amplifier?
Our amplifiers have built in power conditioners and surge protection - over voltage, under voltage, surge and spike protection, as well as lightning arrestors. Every component is designed to allow for maximized performance of the amp.

If an external power conditioner is used, it could limit the peak current capabilities of the amp. This can cause clipping which can harm speakers, or cause internal damage to the amplifier itself.
