Additional features include 59 steps gain control switch, 59 steps auto-transformer (C Core), 90 degree auto-transformer installation, flexible GND usage combination, and more.<\/p>\n<p>PPA-02B is also an entirely passive design with literally zero extra power sources plugged into the audio signal path, meaning that no power is required and neither distortion nor interference are added by active components or power lines to this device. All these are 100% designed and handcrafted in Hong Kong.<\/p>\n\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n\t<div id=\"col-1099750015\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div

best a pre-amplifier can offer.<\/p>\n<p>The design of PPA-02B is based on our proven VR-connected transformers to provide smooth mechanical 59 steps volume control switch from 20dB-80dB. Additional features include 59 steps gain control switch, 59 steps auto-transformer (C Core), 90 degree auto-transformer installation, flexible GND usage combination, and more.<\/p>\n<p>PPA-02B is also an entirely passive design with literally zero extra power sources plugged into the audio signal path, meaning that no power is required and neither distortion nor interference are added by active components or power lines to this device. All these are 100% designed and handcrafted in Hong Kong.<\/p>\n","protected":false},"featured_media":1743,"comment_status":"open","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false},"product_brand":[],"product_cat":[77],"product_tag":[],"class_list":["post-1773","product","type-product","status-publish","has-post-thumbnail","product_cat-passive-preamps","first","instock","sale","shipping-taxable","purchasable","product-type-variable","has-default-attributes"],"_links":{"self":[{"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/product\/1773","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/comments?post=1773"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/media\/1743"}],"wp:attachment":[{"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/media?parent=1773"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/product_brand?post=1773"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/product_cat?post=1773"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/staging.audiokafe.com\/en\/wp-json\/wp\/v2\/product_tag?post=1773"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
