Quantum ES 4 Interface Bundle
The PreSonus Quantum ES 4 is a 4x4 USB-C desktop audio interface built for producers, musicians, and creators who need high-fidelity recording in the studio or onstage. It provides four MAX-HD mic preamps with +75 dB gain and front-facing instrument inputs codeveloped with Fender engineers. The bundle adds Polsen HPC-A30 closed-back studio monitor headphones and 20-foot XLR cables for a complete starter kit.
Connectivity and I/O Flexibility
The interface connects to Mac, Windows, iOS, or Android devices via USB-C and delivers four line outputs plus two independent headphone outputs for flexible monitoring. Auto Gain and 48V phantom power simplify microphone setup, while loopback functionality supports streaming workflows. Bright LED metering gives immediate visual feedback on signal levels without requiring software meters.
Conversion and Latency Performance
High-performance 24-bit / 192 kHz AD/DA converters capture and reproduce audio with detailed clarity during extended sessions. Low-latency operation remains stable when tracking multiple sources simultaneously, and the +75 dB preamp headroom handles dynamic material without added noise. The desktop form factor keeps controls accessible for real-time adjustments throughout long recording or live streaming periods.

Questions about this item
How much gain do the four MAX-HD mic preamps provide before I need an external booster?
Each preamp delivers up to 75 dB of gain, so most dynamic and condenser mics can be driven cleanly without extra hardware.
What happens to fan noise and chassis temperature when the interface runs a full session all day?
The unit uses passive cooling, so it stays silent; the metal chassis dissipates heat and remains warm but safe to touch during extended use.
Which cables and software must I already have to start recording with this bundle?
The box includes a 5-foot USB-C cable, two 20-foot XLR cables and the headphones; you only need a computer or mobile device with a USB-C port and a DAW such as the bundled Studio One Pro.
