The Avalon U5 is a professional Class A preamp and DI box that delivers high-voltage discrete audio performance, pristine headroom up to +30dB, ultra-high 3M ohm input impedance and a six-position passive tone shaping network for enhanced instrument tone. Professional Class A Design Avalon builds the U5 around a high-voltage Class A, fully discrete topology that provides exceptional clarity, musical detail and extended frequency response from 5Hz to 100kHz at ±0.5dB. This pure analogue design offers extremely low noise at -100dBu, high headroom with up to +30dBu output level and very low distortion, ensuring consistent sonic authority whether in a live rig or a studio chain. Tone Shaping and Headroom The U5 features a variable-gain circuit with up to +30dB of clean amplification and a six-position passive tone selector. Each curve enhances harmonic richness, delivering body to bass instruments and smooth presence to acoustic sources. A high-cut filter rolls off extreme high-frequency content at 8kHz to remove unwanted noise, while an active signal LED offers visual level monitoring. Connectivity and Routing Versatility Avalon equips the U5 with dual balanced XLR outputs for microphone and line-level routing, alongside a dedicated headphone amplifier output for direct monitoring. A high-power speaker input handles amplifier outputs up to 400 watts, allowing the unit to capture the sound of an amp power stage. A ground-lift switch eliminates hum caused by ground loops, and an active-to-thru selector provides isolated routing flexibility. Build and Power A robust internal toroidal power supply ensures low noise and stable current delivery, matching the build quality associated with professional touring and studio environments. The U5 arrives in a half-rack 2U chassis with stainless-steel hardware and the option to mount one or two units in a 19-inch rack system. Why Choose the Avalon U5 • Achieve rich, detailed tone for bass and acoustic instruments• Record or perform with extremely low noise and huge headroom• Shape sound instantly with musical pre-set tone curves• Use with amps, studio rigs, PA systems and headphones• Benefit from rugged build and reliable power supply for long-term professional use
