My Home RTX sounds like it's distorting. Why?

The Home RTX may distort if you're feeding audio to the RTX directly from your stereo components; it was not designed to receive audio this way. Use a headphone jack, or a stereo auxiliary output to feed the RTX an audio signal. Standard consumer line level is rated + or - 4dB, and the RTX is rated + or -6dB. On paper, all stereo AUX outputs should feed the RTX a clean, clear audio signal. Even so, some customers have reported a distorted signal when using an auxiliary output from their home stereo receiver. In such cases, Miccus Inc. recommends purchasing a line level controller.
