P-307 is the control center of today\u2019s high end sound systems. Its two main functions are source selection and volume control. Every effort has been made to keep P-307 as accurate as possible.<\/p>\n

To avoid unwanted interactions with adjacent source components, P-307 uses high-quality relays and switching designs to ensure that every source is intact. Thus all sources remain separate from one another and from the power amplifier and cables.<\/p>\n

In the digital age, analog preamplifiers remain the most reliable and neutral-sounding component of controlling volume. P-307 uses a superior attenuator
\nthat offers a neutral sonic performance.<\/p>\n

Since AC power supply generates noise, P-307\u2032s power supply is housed in a separate chassis. Thus P-307\u2032s audio circuits are exposed only to quiet, regulated DC power and the audio signals itself.<\/p>\n","protected":false},"featured_media":37731,"comment_status":"open","ping_status":"closed","template":"","meta":{"jetpack_post_was_ever_published":false,"jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":[]},"product_cat":[878],"product_tag":[787,871],"class_list":["post-37709","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-usher-audio","product_tag-preamplifier","product_tag-usher-audio","description-off"],"jetpack_publicize_connections":[],"yoast_head":"\nPreamplifier Usher P-307A - SaigonStereo<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.saigonstereo.com\/home\/san-pham\/preamplifier-usher-p-307a\/\" \/>\n<meta property=\"og:locale\" content=\"vi_VN\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Preamplifier Usher P-307A - SaigonStereo\" \/>\n<meta property=\"og:description\" content=\"P-307 is the control center of today\u2019s high end sound systems.
