PreSonus QUANTUM ES 4

USB Audio Interface / HN270182
Presonus Quantum ES 4 is a modern 4x4 USB-C audio interface with premium quality in a desktop format.

Guaranteed audio quality
The Quantum ES models offer excellent audio quality in 24 bit / 192 kHz resolution and transducers with a dynamic range of 113 dB. A major innovation is the new generation of MAX-HD microphone preamplifiers, which provide a huge gain of up to +75 dB. Guitarists will also love the Quantum series, as specially designed high-impedance circuits for guitars and basses in collaboration with Fender engineers promise a truly great sound. All this is complemented by an exceptionally low latency audio interface and fine-tuned drivers.

Connectivity
Quantum ES 4 provides four input and four output channels. It has four microphone preamps, while four line-level signals or a combination of both can alternatively be connected as part of the combined inputs. Two instrument inputs are located on the front panel. The four analogue outputs are primarily for connecting listening monitors, while users will also be pleased to find two headphone outputs. The interface is complemented by analogue MIDI in/out mini inputs.

Useful features
The audio interface also offers advanced features such as Auto Gain for automatic volume adjustment and the Universal Control app for controlling sound card functions from a computer or mobile phone. The interface is powered via the USB-C bus.

Software
As part of your product purchase, you get a six-month subscription to the Studio One+ software collection, which includes a wide range of recording tools, led by the cutting-edge Studio One DAW and a host of exclusive content in the form of plug-ins and virtual instruments.
