The USB Audio Interface for Guitarists OverviewIntroducing Blackstar’s POLAR audio interface, designed specifically for anyone who records guitar.POLAR provides the ultimate solution for these customers, with three clear reasons to purchase:1. Feel and response of a real guitar ampThe only audio interface in the market with a FET input stage and “Enhance” feature that mimics the behaviour, characteristics, and electronics normally found on the input stage of a valve guitar amplifier. Plugging a guitar directly into a normal audio interface produces an anaemic signal with peaky transients, which makes playing through amp plugins sound like… a plugin, not an amp. With the flick of a switch, POLAR’s “Enhance” feature makes all software amp plugins sound better by restoring the touch, feel and response of real amps. Works perfectly with pedalboards, no need for D.I. boxes or extra hardware.2. Setting levels made foolproofOur innovative input stage will never digitally clip, allowing the user to drive the interface like an amp. The input stage has an impressive amount of headroom running on +/- 12V giving 24V headroom, an outstanding comparison to competitor units at 5V. Setting guitar input levels and improving your tone has never been easier. We put an equal amount of effort into designing the POLAR MIC preamps, which boast a response that matches one of the most famed preamps in studio history: the Neve 1081. In a blind A/B setup, the POLAR sounded identical to thevintage Neve. Additionally, the “Enhance” function on the MIC input acts as a gentle high-frequency lift that adds just the right amount of air and clarity to vocals.3. Quick and simple to useWhile “Enhance” improves feel, it was also engineered with an input stage that can never digitally clip for foolproof input level setting. Users can set levels quickly without worrying about clipping, allowing them to focus on the most important part: the music.POLAR’s innovative features, alongside an incredibly low noise floor (115db), 48V phantom power and headphone outputs that can drive both high and low impedance models, make POLAR the go-to audio interface for all musicians who record guitar and audio. 2-channel versions FET high headroom +/-24V inputs,low noise -121dB INST “Enhance” switch reacts like the inputstage of a valve amplifier INST “Enhance” input never clips, foolproofinput level setting MIC “Enhance” adds air and clarity MIC preamp same response as Neve 1081 Headphones Outputs Monitor Outputs 48V Phantom PowerPlusAbleton Live LiteRelab lx489 EssentialsPolar Control SoftwareSpecification Included FREE SoftwareSpecification Blackstar Polar 2OverviewNumber of Microphone Preamps 2Phantom Power Yes, 48VInstrument Inputs 2Line Inputs 2Line Outputs 2Headphone Outputs 1Loopback YesConnectivity USB Type-CProtocol USB 2.0Form Factor DesktopSimultaneous I/O 4 x 4 (including Loopback inputs)A/D Resolution 24-bit/192 kHzBus Powered Yes (960mA)Supported Sample Rates 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHzMicrophone inputsFrequency Response 20-20kHz ±0.1dBDynamic Range 109dB (A-Weighted)THD+N -101dB (-103dB A-Weighted); 0dB Gain, 950mVrms, 20Hz-24kHz BWNoise EIN -121dBu (A-Weighted)Maximum Input Level 2dBuGain Range 53dBImpedance 3.3kΩLine inputsFrequency Response 20-20kHz ±0.2dBDynamic Range 112dB (A-Weighted)THD+N -85dB (-85dB A-Weighted); 8dB Gain, 380mVrms, 20Hz-24kHz BWMaximum Input Level 10dBuGain Range 55dBImpedance 500kΩSpecificationInstrument inputsFrequency Response 20-20kHz ±0.2dBDynamic Range 112dB (A-Weighted)THD+N -82dB (-81dB A-Weighted); 3dB Gain, 630mVrms, 20Hz-24kHz BWMaximum Input Level 10dBuGain Range 46dBImpedance 500kΩLine outputs (Balanced)Frequency Response 20-20kHz ±0.15dBDynamic Range 93dBTHD+N -80dBMaximum Output Level 12.8dBuImpedance 1kHeadphone outputsFrequency Response 20-20kHz ±0.15dB @ 33Ω / 300ΩDynamic Range 110dB @ 33Ω107dB @ 300ΩTHD+N -83dB @ 33Ω-85dB @ 300ΩMaximum Output Level 7dBu into 33Ω15.2dBu into 300ΩMaximum Output Power 85mW into 33Ω66mW into 300ΩImpedance 10ΩAnalogue to Digital ConverterTHD+N -100dB THD+NDynamic Range 114dBDigital to Analogue ConverterTHD+N -100dB THD+NDynamic Range 114dBPowerUSB 960mAExternal (Optional) 4.8WAccessory USB A to DC cable, USB A to C cable
