The \"Magic Eye\" tube is perhaps the most eye-catching visual feature of this preamp and something everyone notices in any rack. In addition to being simply fun and another way to impress clients, this visual treatment complements the rich vintage character of the preamp. The \"eye\" closes near optimal output levels.\u003cbr\u003eFREDENSTEIN MAGIC PRE follows what could be considered a very traditional topology that uses both an input transformer and an output transformer. Both are high quality American transformers. In particular, the steel core output transformer is a very important sound shaping component that helps produce a smooth vintage feel without being dark or just \"mid-high\" or mushy.\u003cbr\u003eA single discrete amplifier is used for the active gain element, and there are no chip-based amplifiers in the signal path. To achieve a high level of performance, the circuit relies on our OPA2 discrete audio op-amp. As in all FREDENSTEIN products, the OPA2 is not a copy of an older design, but is a completely new design made in SMT technology with matched and integrated dual input transistors to ensure significantly improved specifications compared to older models. The OPA2, in the tradition of similar modules, is encapsulated and can be replaced without tools. Its industry standard pin-out makes it compatible with many other amplifier modules.\u003cbr\u003eA high impedance 2 MOhms direct input is located on the front panel, accepts unbalanced signals, the rear microphone input is automatically disconnected when a plug is inserted into the DI connector.\u003cbr\u003eFeatures include a maximum gain of 70 dB, a 20 dB pad and Phantom-Power support, plus a new feature simply called \"Color\". The \"Color\" switch is designed to produce a tube-like harmonic content that, while not drawing attention to itself, can bring certain sounds to life and bring them forward in the mix and make them more detailed and dimensional. While the color circuit increases distortion, the audible effect is so subtle that few people would ever describe the effect as \"distorted\".\u003cbr\u003eLike all FREDENSTEIN products, FREDENSTEIN MAGIC PRE is designed by a German-American team and manufactured in Taiwan.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eFrequency response: 20 Hz - 40,000 Hz, +\/- 1 dB\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch4\u003eDistortion\u003c\/h4\u003e\n\u003cul\u003e\n\n\u003cli\u003e1kHz: \u0026lt;0.03% at +4 dBu output level \/ \u0026lt;0.015% at +20 dBu output level \/ \u0026lt;0.04% at +26 dBu output level (clip at +28 dBu)\u003c\/li\u003e\n\n\u003cli\u003e50Hz: \u0026lt;0.08% at +4 dBu output level \/ \u0026lt;0.08% at +20 dBu output level\u003c\/li\u003e\n\n\u003cli\u003e10kHz: \u0026lt;0.02% at +4 dBu output level \/ \u0026lt;0.05% at +20 dBu output level\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cul\u003e\n\n\u003cli\u003eInput Noise: \u0026lt;-127 dB\u003c\/li\u003e\n\n\u003cli\u003eInput Impedance: \u0026gt;1600 Ohms\u003c\/li\u003e\n\n\u003cli\u003eDI Impedance: \u0026gt;2 MOhms\u003c\/li\u003e\n\n\u003cli\u003eMaximum input level: +10 dBu, Pad activated\u003c\/li\u003e\n\n\u003cli\u003eMaximum DI input level: +18 dBu unbalanced\u003c\/li\u003e\n\n\u003cli\u003eOutput Impedance: 600 ohms\u003c\/li\u003e\n\n\u003cli\u003eMaximum output level: +26 dBu\u003c\/li\u003e\n\n\u003cli\u003eInput attenuator: -20 dB (switchable)\u003c\/li\u003e\n\n\u003cli\u003eMaximum Gain (XLR): 70 dB\u003c\/li\u003e\n\n\u003cli\u003eMinimum Gain: 35 dB\u003c\/li\u003e\n\n\u003cli\u003eMinimum Gain with 20dB Pad activated: 15 dB\u003c\/li\u003e\n\n\u003cli\u003eMaximum Gain (DI): 42 dB\u003c\/li\u003e\n\n\u003cli\u003eMinimum Gain: 8 dB\u003c\/li\u003e\n\n\u003cli\u003eMinimum Gain with 20dB Pad activated: -12 dB\u003c\/li\u003e\n\n\u003cli\u003eCurrent Increase: +100mA, -160m\u003c\/li\u003e\n\n\u003cli\u003eDistortion with Color activated: approximately 0.1% at -10 dBu output level \/ approximately 1% at -5 dBu output level \/ approximately 3% at 0 dBu output level \/ approximately 4.5% at +24 dBu output level\u003c\/li\u003e\n\n\u003cli\u003eFrequency Response: 20 Hz - 20,000 Hz, +\/- 1 dB\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Fredenstein","offers":[{"title":"Default Title","offer_id":53993909649741,"sku":"FREDMAGPRE","price":465.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/94695-large_default.jpg?v=1779947579","url":"https:\/\/musicdelivery.net\/en\/products\/fredenstein-magic-pre-preamplificatore-serie-500","provider":"Music Delivery","version":"1.0","type":"link"}
