The input is isolated by a microphone transformer with a low 1:2 ratio, which forces the discrete stage rather than the transformer to provide most of the amplification.\u003c\/p\u003e\n\n\u003ch3\u003eGain you can write down and recall\u003c\/h3\u003e\n\u003cp\u003eThree singers in one session, each at a different level, and a week later you need a punch in that matches. The VSP-2 solves that in hardware: main gain sits on a ten position Grayhill switch in 6 dB steps across a 12 to 72 dB range, and fine trim runs on a separate 41 click Alps pot covering 0 to 6 dB. Both values can be noted and reproduced click for click, including across the two channels when you are working a stereo pair.\u003c\/p\u003e\n\n\u003ch3\u003eAn instrument input with nothing in the way\u003c\/h3\u003e\n\u003cp\u003eThe Instrument In socket is an unbalanced input wired straight to the Twin OPA stage with no circuitry in between, which makes it a genuine DI. Throw the switch and play; the output mutes briefly so nothing cracks through the monitors. For microphone work there is ramped 48 V phantom power, a 20 dB pad that does not change the input impedance, a polarity switch and a 12 dB per octave low cut filter at either 80 Hz or 120 Hz. The signal LED reads green across the usable range and red at +19 dBu, with no ambiguous orange state in between.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo independent channels in dual mono configuration\u003c\/li\u003e\n\u003cli\u003eFully discrete Twin Op Amp OPA 1976 gain stage\u003c\/li\u003e\n\u003cli\u003eTransformer isolated microphone input with a 1:2 ratio\u003c\/li\u003e\n\u003cli\u003eGain from 12 to 72 dB on a Grayhill switch in 6 dB steps\u003c\/li\u003e\n\u003cli\u003eFine gain trim of 0 to 6 dB on a 41 click pot\u003c\/li\u003e\n\u003cli\u003eInstrument input wired directly to the input stage\u003c\/li\u003e\n\u003cli\u003eOutput muted when switching to the instrument input\u003c\/li\u003e\n\u003cli\u003eLow cut filter at 12 dB per octave, 80 Hz or 120 Hz\u003c\/li\u003e\n\u003cli\u003eRamped 48 V phantom power\u003c\/li\u003e\n\u003cli\u003e20 dB pad that does not affect input impedance\u003c\/li\u003e\n\u003cli\u003ePolarity reverse switch on each channel\u003c\/li\u003e\n\u003cli\u003eTwo state signal and clip LED with no ambiguous middle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInput impedance: 1.5 kOhm\u003c\/li\u003e\n\u003cli\u003eGain range: 12 to 72 dB plus 0 to 6 dB fine trim\u003c\/li\u003e\n\u003cli\u003eDynamic range: 116 dB at 36 dB gain\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz to 35 kHz (±1 dB) at 36 dB gain\u003c\/li\u003e\n\u003cli\u003eMaximum input level at 20 Hz: +9 dBu\u003c\/li\u003e\n\u003cli\u003eMaximum output level: +24 dBu into 600 Ohm, balanced floating\u003c\/li\u003e\n\u003cli\u003eNoise: -81 dBu (20 Hz-22 kHz, unweighted, RMS) at 36 dB gain\u003c\/li\u003e\n\u003cli\u003eElectronically floating output, That 1646 type\u003c\/li\u003e\n\u003cli\u003eClip LED threshold: +19 dBu at the output\u003c\/li\u003e\n\u003cli\u003eLinear power supply with toroidal transformer\u003c\/li\u003e\n\u003cli\u003eMains voltage: 115 V or 230 V\u003c\/li\u003e\n\u003cli\u003eSteel chassis with electrostatic and magnetic shielding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"VERTIGO SOUND","offers":[{"title":"Default Title","offer_id":58444336333132,"sku":"28979","price":3760.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/9854\/1644\/files\/VERTIGOSOUNDVSP-2MicPre.jpg?v=1786977905","url":"https:\/\/noiseroom.lt\/lt\/products\/vertigo-sound-vsp-2","provider":"Noise Room","version":"1.0","type":"link"}
