The Alto is a technology-rich pro audio headphone and nearfield monitor amplifier capable of driving up to four pairs of headphones. The Alto is the perfect tool for monitoring in todayโ€™s high-resolution environment. It offers 50 watts per channel for nearfield monitoring, plus enough drive for its four headphone outputs simultaneously, via one front-panel 3.5 mm, one 4.4mm balanced jack and two 6.35
mm outputs.

Designed to fit into 19-inch racking, the 1U-tall Alto also benefits from both balanced and unbalanced inputs, plus a pair of balanced XLR outputs for bypass/external monitor control.

Headphone or Monitor Amplifier

The Alto is a meticulously designed headphone and nearfield monitor amplifier, capable of driving up to four pairs of headphones and smaller loudspeakers. Notably, it marks our first product to include a 4.4 mm Pentaconn TRRRS output (pseudo balanced), catering to the increasing popularity of balanced transmission in high-end headphones.

A/B Simultaneous Outputs

The Alto features four fascia-mounted headphone outputs, powered ULTIMA technology. It features one 3.5 mm output; two 6.35 mm (1/4-inch); plus a single 4.4 mm Pentaconn. The array of outputs, not only facilitates easy A/B comparisons, but also allows multiple users to listen simultaneously.

The Altoโ€™s ULTIMA topology introduces the companyโ€™s dual-feed-forward error-correction technology, which monitors and then immediately corrects signalsbeforethe output stage.

Compact yet powerful, the Altoโ€™s dimensionsโ€”slightly larger than A5โ€”make it easy to place in any audio system, including desktop set-ups, living spaces and dedicated hi-fi systems.
