Blackstar Polar-4

Description

POLAR 4 is a 4-channel USB audio interface built by guitarists and designed for guitarists.
It features 4 FET input channels for instruments, line, and microphone, a headphone amplifier, +48V phantom power for condenser microphones, balanced outputs for professional monitoring, visual level meters, and Blackstar's unique 'Enhance' switch. Engaging the 'Enhance' switch activates exclusive electronics in the signal path that replicate the input stage of tube guitar amplifiers.
This circuit mimics the behavior and characteristics of tube amps, improving tone, touch, feel, and response. With POLAR 'Enhance' enabled, the innovative Blackstar input stage will never suffer from digital clipping: no more messy recordings, no more hassle, and no more confusion when it comes to setting the 'right' levels.
POLAR allows the musician to manage the interface like the preamp gain of a real amplifier.

Features: 4-channel audio interface designed for guitar recording.
FET input stage enhances tone and signal quality and accommodates a wide range of instrument types, effect pedals, and microphones.
The 'Enhance' function introduces electronics into the signal path that replicate the sound of a guitar amplifier. 'Enhance' completely prevents digital clipping on instrument inputs. Use this interface as if it were a real amplifier and free yourself from the hassle of setting the 'right' levels.
The 'Enhance' function on microphone or line inputs provides natural clarity and brightness to vocal and acoustic guitar recordings. The 'Enhance' function eliminates the need for additional hardware and expensive DIs to capture a high-quality guitar signal. It's all built into POLAR. Includes ST.James Suite, Ableton Live Lite, ReLab LX480 Essentials Reverb, Melodyne Essential, and much more*.
Polar 4 features two headphone outputs and a monitor output, with independent control for monitor and headphones.
Microphone preamplifier based on the most famous vintage studio preamps.
Includes 'POLAR Control' software for fine-tuning levels, panning, and monitor routing. Operates on USB 3.0 bus power, with a +48V switch for microphones requiring phantom power.
