PW Audio Quickstep Amplifier

The Quickstep is highly versatile thanks to its adjustable gain settings and low output impedance of less than 1 ohm. It is designed to drive a wide range of headphones, from sensitive in-ear monitors to more demanding over-ear models, while maintaining a clean, balanced signal.

Yes, the Quickstep supports external power supplies between 6V and 15V DC. This allows for continuous desktop use without relying solely on the internal 9V battery.

The amplifier uses a discrete volume control system with 31 distinct steps, each spaced at 1.5 dB intervals. This provides a more precise and balanced adjustment compared to traditional potentiometers, ensuring perfect channel matching at lower volumes.

Yes, the Quickstep features a fully balanced architecture from input to output. This design helps minimize noise and interference, resulting in a cleaner, more dynamic audio performance.

The Quickstep is built with a durable aluminum enclosure designed for portability. While it is a robust, high-performance device, its compact form factor makes it easy to integrate into a mobile audio stack.

The use of four OPA209 amplifiers is central to the device's balanced design. These components are chosen for their ability to deliver high-resolution audio with a smooth, natural sound signature that mimics the warmth of classic amplifier designs.
