Independent shopping perspective
The Korena take
The Quantum ES 4 expands the format to four mic/line inputs, two dedicated instrument inputs, four outputs, and two headphone outputs. Four MAX-HD preamps provide up to +75 dB of gain, while Auto Gain offers a quick way to establish input levels before recording. It records at 24-bit/192kHz and uses low-latency drivers for real-time monitoring while tracking. At 6.2 by 8.4 inches and 1.8 lb, it remains compact, with USB bus power and a second USB-C port for auxiliary power.
Strong match
Who this is for
- Recording several microphones or line sources while retaining two direct instrument inputs.
- Sessions where two headphone outputs support separate monitoring connections.
- Tracking vocals, instruments, virtual instruments, or effects with low-latency monitoring.
Consider the trade-offs
When to look elsewhere
- Sessions requiring more than four simultaneous input and output channels.
- Computers running earlier than macOS 10.13 or Windows 10.
- Rigs without provision for an additional USB power source when one is required.
