Quantum ES4 + RCM PRO

This bundle pairs PreSonus' Quantum ES4 4x4 USB-C recording interface with the Rockville RCM PRO condenser microphone, giving a solo creator or small studio a complete signal path from mic to computer. The ES4 powers the RCM PRO through one of its four MAX-HD preamps, which supply up to 75 dB of clean gain plus 48V phantom power, and the Auto Gain button finds the right level in seconds. The RCM PRO's 25mm cartridge and cardioid pattern pick up vocals with a wide, even diaphragm response, while its zinc metal body and one-piece steel head resist the shock noise that cheaper mics pick up. Twin Samsung capacitors help keep the signal stable even through loud passages. The mic ships with both an XLR-to-XLR cable for connecting to the ES4's combo input and a 3.5mm-to-XLR cable for direct computer use, along with a metal shock mount and a large wind screen to control plosives. Beyond the microphone input, the ES4 still offers two Fender co-developed guitar and bass inputs, loopback audio, and built-in speaker switching, so the same interface scales from a single vocal chain to a fuller band session.
