Quantum ES4 Recording Interface + ASM4 Studio Monitors

The Quantum ES4 bundle turns a laptop into a complete recording and monitoring station, pairing PreSonus' 4x4 USB-C interface with a pair of Rockville ASM4 active studio monitors and the speaker cables needed to connect them. The ES4 captures up to four sources at once through MAX-HD preamps with up to 75 dB of gain, plus two Fender co-developed guitar and bass inputs for guitar and bass. An Auto Gain button and illuminated encoder make dialing in levels quick, and built-in speaker switching lets a producer flip between monitor pairs without touching a cable. The ASM4 monitors deliver a flat, DSP-tuned response with clear bass down to 50Hz from their 4-inch woofers and silk dome tweeters, so mixes translate accurately from the studio to other systems. Beyond studio use, the ASM4s add Bluetooth 5.0 streaming and an optical input, making them just as useful for casual listening or connecting to a TV. Two 10-foot RCTT1610 cables, built with 100% copper conductors, connect the interface's outputs to the monitors with minimal signal loss. This combination suits musicians and podcasters who want to record and monitor their mix from the same desk without adding separate audio gear.
