Pure Direct Analog Path Offers Interference-Free Hi-fi Amplification At the touch of a button on the front panel, Pure Direct Analog Path mode brings higher fidelity to vinyl, SACD, or CD playback via your home theater. With this mode engaged, every digital circuit is physically shut down to prevent electrical interference on analog audio signals. Signals pass directly from the phono or analog audio inputs to the amplifiers and arrive at your front loudspeakers in pure analog form. The improvement in audio quality is quite dramatic. With subtle interference erased, you can hear more detail deeper down in the mix, while the rich tonal character of vinyl is displayed in all its analog glory. This mode also lets your home theater receiver double as a dedicated analog stereo amplifier for quality source components, if space or budget precludes a dedicated hi-fi stereo system.
