Apogee groove

The first-generation Apogee Groove, released in 2015, is a portable USB digital-to-analog converter (DAC) and headphone amplifier. Designed for Mac and PC, it delivers studio-quality audio through features like Quad Sum DAC technology and Constant Current Drive. Key features Audio quality: The Groove supports high-resolution audio up to 24-bit/192kHz. Quad Sum DAC: It utilizes four digital-to-analog converters per channel to lower distortion and improve dynamic range. Constant Current Drive: This adaptive amplifier technology ensures a smooth frequency response with any set of headphones, regardless of their impedance. This makes it an ideal match for high-impedance headphones (150Ω–600Ω). Computer powered: The unit is bus-powered, meaning it draws all its necessary power directly from the connected computer's USB port. Portable design: The device features a compact, durable aluminum enclosure, with a non-slip rubber pad on the bottom and a simple two-button volume control. Status indicator: LEDs indicate signal levels and volume adjustments. Plug-and-play: It is class-compliant with Mac computers, meaning no special driver is needed. For Windows, a driver from Apogee's website is required.
