{"product_id":"blackstar-polar-4","title":"Blackstar Polar 4 Audio Interface","description":"\u003cp\u003eThe Blackstar Polar 4 is a 4-channel USB-C audio interface built for guitarists who record, with four combo inputs, two headphone outputs, four balanced outputs and 5-pin MIDI In and Out. Every input takes a microphone, a line source or an instrument, and the instrument path runs through a high-headroom FET input stage. The Enhance switch on each channel adds a circuit modeled on the input stage of a valve amp, so amp-sim plugins feel more like a real amplifier, and it stops the instrument inputs from clipping digitally.\u003c\/p\u003e\n\n\u003ch3\u003eEnhance for Guitar and Vocals\u003c\/h3\u003e\n\u003cp\u003eWith a guitar on the 1\/4-inch input and INST selected, Enhance switches in the valve-style input circuit. With a microphone on XLR, it adds a gentle high-shelf lift for more clarity and air on vocals and acoustic guitar. The mic preamps take their voicing from classic vintage studio preamps, and a +48V switch powers condenser microphones.\u003c\/p\u003e\n\n\u003ch3\u003eTwo Headphone Mixes and MIDI\u003c\/h3\u003e\n\u003cp\u003eThe included POLAR Control app builds separate mixes: Outputs 1 and 2 feed your monitors and Headphones 1, while Outputs 3 and 4 feed Headphones 2, so a second player can hear a different blend. A virtual mix with loopback handles streaming. The 5-pin MIDI ports connect a controller or hardware synth to your DAW. The software bundle includes the full St. James plugin suite, Ableton Live Lite, ReLab LX480 Essentials and Melodyne Essential.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 combo XLR \/ 1\/4-inch inputs for microphone, line and instrument\u003c\/li\u003e\n  \u003cli\u003eHigh-headroom FET instrument inputs\u003c\/li\u003e\n  \u003cli\u003eEnhance switch on each channel: valve-style input stage on instrument, high-shelf clarity on microphone\u003c\/li\u003e\n  \u003cli\u003eEnhance prevents digital clipping on the instrument inputs\u003c\/li\u003e\n  \u003cli\u003eLine\/Inst switch on each channel and +48V phantom power\u003c\/li\u003e\n  \u003cli\u003ePeak-hold LED input and output meters\u003c\/li\u003e\n  \u003cli\u003e4 balanced 1\/4-inch TRS outputs with monitor level control for Outputs 1 and 2\u003c\/li\u003e\n  \u003cli\u003e2 headphone outputs with separate level controls and separate mixes\u003c\/li\u003e\n  \u003cli\u003e5-pin MIDI In and Out\u003c\/li\u003e\n  \u003cli\u003ePOLAR Control mixer software with direct monitoring and loopback\u003c\/li\u003e\n  \u003cli\u003eUSB-C, bus powered, with an optional DC 5V input\u003c\/li\u003e\n  \u003cli\u003eKensington lock slot\u003c\/li\u003e\n  \u003cli\u003eSoftware bundle: St. James plugin suite, Ableton Live Lite, ReLab LX480 Essentials, Melodyne Essential and more\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 4 combo XLR \/ 1\/4-inch (mic, line, instrument)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 4 balanced 1\/4-inch TRS line outputs, 2 1\/4-inch headphone outputs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMIDI:\u003c\/strong\u003e 5-pin In and Out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSimultaneous I\/O:\u003c\/strong\u003e 6 x 6, including loopback\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution:\u003c\/strong\u003e 24-bit, up to 192 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSample rates:\u003c\/strong\u003e 44.1, 48, 88.2, 96, 176.4 and 192 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic preamp gain range:\u003c\/strong\u003e 53 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic EIN:\u003c\/strong\u003e -121 dBu (A-weighted)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic frequency response:\u003c\/strong\u003e 20 Hz to 20 kHz, ±0.1 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic dynamic range:\u003c\/strong\u003e 109 dB (A-weighted)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic input impedance:\u003c\/strong\u003e 3.3 kΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMic maximum input level:\u003c\/strong\u003e 2 dBu\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstrument input:\u003c\/strong\u003e 500 kΩ impedance, 46 dB gain range, 10 dBu maximum input\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLine input:\u003c\/strong\u003e 500 kΩ impedance, 55 dB gain range, 10 dBu maximum input\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLine output maximum level:\u003c\/strong\u003e 12.8 dBu (balanced)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeadphone output power:\u003c\/strong\u003e 85 mW into 33 Ω, 66 mW into 300 Ω\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e USB-C, USB 2.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e USB bus power or optional DC 5V input\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e macOS 10.15 or later, Windows 8 or later\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBlackstar Polar 4\u003c\/li\u003e\n  \u003cli\u003eQuick Start Guide\u003c\/li\u003e\n  \u003cli\u003eUSB-A to USB-C cable\u003c\/li\u003e\n  \u003cli\u003eUSB-A to DC cable\u003c\/li\u003e\n  \u003cli\u003eSafety information sheet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Blackstar","offers":[{"title":"Default Title","offer_id":67380242415865,"sku":"POLAR-4","price":499.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/blackstar-polar-4-1.jpg?v=1792174543","url":"https:\/\/blackoutaudio.com\/products\/blackstar-polar-4","provider":"Blackout Audio","version":"1.0","type":"link"}
