It provides clean, reliable phantom power for one or two condenser microphones in a rugged, compact, and portable unit. Innovative low power circuitry generates the higher voltage necessary for powering microphones while maximizing battery life. The Phantom II Pro installs inline between your microphone and a balanced line input on your gear. Balanced lines offer increased immunity to external electrical noise, such as hum. Since a balanced system minimizes induced noise, it is the preferred method of connecting audio gear, especially when long lengths of cable are used.\u003c\/p\u003e\u003cp\u003eThe Phantom II Pro is an invaluable tool in application areas including (but not limited to): home or professional recording studios, live sound, PA, permanent installs, DJ, AV, podcasting and broadcasting.

Each has a precisely voiced EQ curve, Warm presets add tube saturation, and OPL presets engage Output Protection Limiting for dynamic control of loud signals and big transients.\n\nEvery preset has a suggested application, but they all have a unique character, so any of them might be an inspiring match for your performance. Theres also a Flat preset for the classic sound of the original Tube MP.\n\nBoth channels feature independent V3 settings, input and output gain controls, and switchable boost, phantom power, and phase reversal.\n\nThe TPS II also adds variable impedance for each microphone input, so you can tailor the response of the preamp to your mics for even more tonal flexibility.\n\nThe front panel features input and output meters and a mic \/ instrument combo jack for each channel, and the rear panel features XLR and 1\/4 connections for mic and line connections.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable Input Impedance\u003c\/li\u003e\n  \u003cli\u003eImproved V3™ Variable Valve Voicing Presets\u003c\/li\u003e\n  \u003cli\u003eLED Input Meter with Analog Output Meter\u003c\/li\u003e\n  \u003cli\u003eEnhanced ART Tube Technology Adds Warmth\u003c\/li\u003e\n  \u003cli\u003eAutomatically switches between instrument and microphone preamp\u003c\/li\u003e\n  \u003cli\u003eWide Frequency Response (5hz\/50kHz)\u003c\/li\u003e\n  \u003cli\u003eEnhanced OPL™ Output Protection Limiter\u003cbr\u003e\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInputs: XLR\u003c\/li\u003e\n  \u003cli\u003eOutputs: XLR, 1\/4\" TRS\u003c\/li\u003e\n  \u003cli\u003eInput Impedance: 5K ohms, 1M ohm\u003c\/li\u003e\n  \u003cli\u003eOutput Impedance: 300 ohms, 150ohms\u003c\/li\u003e\n  \u003cli\u003eMaximum Input Level: +19dBu (XLR), +22dBu (1\/4\")\u003c\/li\u003e\n  \u003cli\u003eMaximum Output Level: +28dBu (XLR), +22dBu (1\/4\")\u003c\/li\u003e\n  \u003cli\u003eMaximum Gain: 74dB - 80dB\u003c\/li\u003e\n  \u003cli\u003eFrequency Response: 5Hz to 50kHz, +\/-.1dB\u003c\/li\u003e\n  \u003cli\u003eTotal Harmonic Distortion: \u0026lt;0.01% (Clean), \u0026lt;0.1%(Warm)\u003c\/li\u003e\n  \u003cli\u003eEquivalent Input Noise: -129dBu (A weighted), -105dBu (A weighted)\u003c\/li\u003e\n  \u003cli\u003eCMRR: \u0026gt;75dB (Typical @ 1kHz)\u003c\/li\u003e\n  \u003cli\u003ePower Requirements: 110-125V AC \/ 50hz\/16W\u003c\/li\u003e\n  \u003cli\u003eDimensions (HWD): 1.75” x 19” x 6.5” (4.5 cm x 48.26 cm x 16.5 cm)\u003c\/li\u003e\n  \u003cli\u003eWeight: 5.5 lbs \/ 2.5 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Applied research technologies\u003cbr\u003eModel: TPSII\u003cbr\u003eSKU: I155029-N-0-WHXX\u003cbr\u003eUPC: 840402015635\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.

Split one input to four outputs. Mix four inputs to one output. Send four stereo sources to their own stereo outputs with independent level controls. Or do any combination of the above.\n\nThe fully passive design means that there is no active circuitry to add noise or distortion, and that no power is required.\n\nAll connections are 1\/4” stereo TRS with intelligent switching. Plugging into a mix input removes the channel from the splitter bus, and plugging into a splitter output removes the channel from the mix bus.

It offers the smooth, musical sound of optical compression for recording, mixing, and mastering.\n\nVisually, the first thing you’ll notice is the robust metering. Each channel has a VU meter that shows the average input or output level, and an LED meter for gain reduction. A master LED meter shows the peak and average output of each channel for precise gain staging.\n\nBoth channels have variable controls for threshold, ratio, attack, release, and output level. The ratio ranges from 2:1 for gentle compression up to 20:1 for hard limiting. The channels can be used independently or linked for stereo operation. When linked, the Channel One controls are global, and the Channel Two output level control adjusts the stereo balance.\n\nThe rear panel features balanced XLR and 1\/4” inputs and outputs, and a switch for +4 dBu or -10 dBV operation.\n\nWhat you’ll notice most is the sound: subtle and natural when used gently, lively and colourful when driven hard. Try one and hear for yourself why the Pro VLA has earned a reputation as a trusted secret weapon and one of the best bang-for-your-buck compressors on the market.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVCA-Less Vactrol Opto-Compression Design\u003c\/li\u003e\n  \u003cli\u003eMastering Quality Audio Signal Path with Tube Gain Stage Enhanced Link Mode – While in stereo link mode, channel 1 level control acts as a master output level and channel 2 becomes a balance control between them, – optimizing the Pro-VLA II for use as a mastering tool\u003c\/li\u003e\n  \u003cli\u003eVariable Threshold, Ratio \u0026amp; Output Controls\u003c\/li\u003e\n  \u003cli\u003eLED Backlit VU Input\/Output Level Metering\u003c\/li\u003e\n  \u003cli\u003eLED Metering Indicates Both Average Level And Peak Hold Accurate\u003c\/li\u003e\n  \u003cli\u003eTen Segment LED Gain Reduction Metering\u003c\/li\u003e\n  \u003cli\u003e+4dBu\/-10dBu Mode Switch Optimizes Pro-VLA II For Interface with Professional OR Consumer Grade Components\u003c\/li\u003e\n  \u003cli\u003eActive Balanced XLR And 1\/4-Inch Inputs \u0026amp; Outputs\u003c\/li\u003e\n  \u003cli\u003eToroidal Transformer Reduces Mechanical \u0026amp; Electrical Hum\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003eInput Impedance: 10K Ω\u003c\/li\u003e\n    \u003cli\u003eMaximum Input Level: +20 dBu (in +4 dBu mode) \/ +10 dBV (in -10 dBV mode)\u003c\/li\u003e\n    \u003cli\u003eMaximum Output Level: +20 dB max\u003c\/li\u003e\n    \u003cli\u003eFrequency Response: 10 Hz to 100 KHz (+\/- 0.5 dB)\u003c\/li\u003e\n    \u003cli\u003eTotal Harmonic Distortion: \u0026lt;0.1% (Typical)\u003c\/li\u003e\n    \u003cli\u003eEquivalent Input Noise:\n        \n      \u003cul\u003e\n          \u003cli\u003e@+4dBu: -99dBu (\"A\" Weighted)\u003c\/li\u003e\n          \u003cli\u003e@-10 dBV: -107 dBu (\"A\" Weighted)\u003c\/li\u003e\n        \u003c\/ul\u003e\n    \u003c\/li\u003e\n    \u003cli\u003eDimensions (DWH): 9.2\" x 19\" x 3.5\" (23.3 cm x 48.3 cm x 8.9 cm)\u003c\/li\u003e\n    \u003cli\u003eWeight: 10.5 lbs (4.76 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Applied research technologies\u003cbr\u003eModel: PROVLAII\u003cbr\u003eSKU: I155498-0-WHXA\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
