You hear the microphone, not the preamp. <\/p>\n<p>The RefPre reference preamplifier from the 500 Series stands out for what it doesn&#8217;t do. It won&#8217;t color your sound. Never, ever. Its transparent design uses minimal circuitry and signal paths.   <\/p>\n<p>If exceptional precision and greater headroom to handle a variety of microphone types\u2014including high-output and ribbon microphones\u2014are among your \u201cmust-haves\u201d for a preamp, this preamp will be the perfect choice for you.<\/p>\n<p>It also includes a switchable +10 dB gain boost and a phantom power safety lock for the tapes.<\/p>\n<p>Designed as an option for the Wolff Console, the RefPre features 60 dB of gain, phantom power, switchable polarity, and a source selector for the front-panel XLR\/INST input. Selecting the ribbon microphone option increases the gain to 70 dB and adjusts the microphone\u2019s impedance. The RefPre is ideal for sampling and emulation microphones, such as the Slate VMS, which require a completely transparent preamp. Pairing it with Earthworks TC25 microphones for toms and kick drums and PM40 microphones for piano yields exceptional results, as does pairing it with the Neumann TLM 103 to add a noticeable presence.   <\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<h3 id=\"toc_0\">Features:<\/h3>\n<ul>\n<li>Transformerless microphone preamp with a stepped rotary switch for repeatable gain adjustment from -10 dB to 60 dB in 10 dB steps<\/li>\n<li>The ribbon microphone circuit provides an additional 10 dB of gain with automatic impedance adjustment and phantom power lockout<\/li>\n<li>+\/-6 dB trim control for precise gain adjustment<\/li>\n<li>Output fader, continuous adjustment from INF to full output<\/li>\n<li>Frequency response: \u00b10.5 dB from 10 Hz to 80 kHz<\/li>\n<li>Low noise and distortion: -125 dBu EIN and 0.0005% distortion at 60 dB of gain<\/li>\n<li>High headroom: +28 dBu output<\/li>\n<li>Switchable 12 dB\/octave 80 Hz high-pass filter<\/li>\n<li>The LED signal indicator glows green when a signal is present and flashes red at +18 dBu, 10 dB below clipping<\/li>\n<li>Front and back panel access for the microphone input<\/li>\n<li>Front-panel instrument input with a dedicated Hi-Z input amplifier, accessed via the MIC\/INST switch<\/li>\n<li>Polarity reverse switch \/ 48V phantom power (output mutes during switching)<\/li>\n<li>All gain adjustments and switches are relay-based for improved reliability<\/li>\n<\/ul>\n","protected":false},"featured_media":343,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[107],"product_cat":[84],"product_tag":[],"class_list":["post-1308","product","type-product","status-publish","has-post-thumbnail","product_brand-wolff-audio","product_cat-wolff-audio","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product\/1308","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/comments?post=1308"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/media\/343"}],"wp:attachment":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/media?parent=1308"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_brand?post=1308"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_cat?post=1308"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_tag?post=1308"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
