If the output level is too high (the Class A\/B output op amp can pump out up to +27 dBu), you can ride the level down with the separate Level control.\u003c\/p\u003e  \u003cp\u003ePressing the “Dual” switch splits the gain between two of our Class A op amps, enabling up to 75 dBu of clean gain, making the Biz a perfect match for ribbon microphones.\u003c\/p\u003e  \u003cp\u003eWith different Gain, Level, and Dual settings the Biz can produce an infinite variety of tonal variations with the same amount of output level. The front panel DI helps you record instruments and line level sources with unrivaled clarity and punch.\u003c\/p\u003e  \u003cp\u003eTwo LEDs clearly indicate signal level for the gain and output stages at a glance, turning green to indicate signal present, yellow for 10 dB below clipping, and red for clipping. The Biz uses two KDJ3 op amps and one KDJ4 op amp.\u003c\/p\u003e    \u003ch3 id=\"toc_1\"\u003eSPECIFICATIONS:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eMaximum output level: +27 dBu\u003c\/li\u003e \u003cli\u003eFrequency response: 10 Hz – 70 kHz +\/- 1db (3 db down at 100 kHz)\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3 id=\"toc_2\"\u003eTransformer input:\u003c\/h3\u003e  \u003cp\u003e\u003cstrong\u003eMic mode\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eMaximum gain 60 dB in single mode\u003c\/li\u003e \u003cli\u003eMaximum gain 75 dB in dual mode\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eLine mode\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eMaximum gain 35 dB in single mode\u003c\/li\u003e \u003cli\u003eMaximum gain 50 dB in dual mode\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3 id=\"toc_3\"\u003eDirect input:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eMaximum gain 30 dB in single mode\u003c\/li\u003e \u003cli\u003eMaximum gain 40 dB in dual mode\u003c\/li\u003e \u003cli\u003eBeginning Serial Number 1600 February 2008:\u003c\/li\u003e \u003cli\u003eOver Current Resettable Fused (prevents any module problem from affecting your rack)\u003c\/li\u003e \u003cli\u003eROHS – Lead Free\u003c\/li\u003e \u003c\/ul\u003e","brand":"Purple Audio","offers":[{"title":"Default Title","offer_id":44451036954727,"sku":"209849","price":549.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/purple-audio-biz-mk-500-series-microphone-preamp-1499-used_209849_1_12df994d-6d2e-4400-9e7c-c654a7625d58.jpg?v=1787095576","url":"https:\/\/vintageking.mom\/products\/purple-audio-biz-mk-500-series-microphone-preamp-1499-used","provider":"Vintage King","version":"1.0","type":"link"}
