Independent shopping perspective
The Quantum ES4 sits at the center of this recording package, joined by a Yamaha HS8 monitor pair, cables, and monitor stands. Its four MAX-HD mic preamps deliver up to 75 dB of gain for multi-source recording, and Auto Gain can handle level adjustment at each input. Fender-engineered instrument inputs are intended for direct guitar and bass recording. Use Universal Control from a computer or mobile device to adjust gain, phantom power, and I/O levels without stopping the session.
