Notes: Capture your creativity with the Quantum ES 4 - the recording interface for self-made musicians and audio creators.
The Culmination Of 30 Years Of Innovation
The ES 4 features four newly redesigned high-definition MAXHD mic preamps with +75 dB of gain - making it ideally suited for today's most popular microphones. Guitarists and bassists will love the instrument inputs, which were co-developed with Fender engineers.
An Auto Gain button sets the perfect gain level for your microphones and instruments, while an illuminated push encoder provides flexible control over gain level and output volume. And bright and responsive LED metering provides easy visual feedback for your inputs and outputs, making it great for self-produced recording.
High Performance Signal Flow
This custom low-latency driver provides exceptionally low audio latencies when recording, and high-performance converters complete the front end to ensure that you sound your best throughout the entire signal chain.
All-New MAX-HD Mic Preamps
The Quantum ES 4 features four newly designed mic preamps with +75 dB of gain. The high-definition MAX-HD preamps are transparent, low-noise, and digitally controlled analogue, making them ideally suited to today's most popular microphones.
Co-Developed With Fender
Built by the best ears in the business, guitarists and bassists will love the instrument input co-developed with Fender engineers - industry experts who designed them specifically for guitar and bass.
Professional Recording Software Included
Leap into 6 months of Studio One+ with access to Studio One Professional Edition, add-ons, and more.
Auto Gain
An Auto Gain button sets the perfect gain level for your microphones and instruments, so you get the perfect take every time.
