Stewart Audio unveils low-power networked amplifier series

The compact footprint of all four products enables simple installation at endpoints.

Stewart Audio has announced the introduction of a family of four low-wattage, networked amplifiers that address the need for lower channel count support at the local amplification stage. The new series, claims the manufacturer, brings the benefits of power-efficient digital audio networking to an underserved customer base, where consultants, systems integrators, dealers and end-users require simple, affordable networked amplifier solutions scaled for smaller zones.

The compact footprint of all four products enables simple installation at endpoints, providing networked amplification to smaller zones – whether for standalone needs in small-to-mid-sized installations, or to provide low-power amplification to smaller, distant zones in larger scale projects. Dual inputs in two models (AV25-2 NET+ CVA50-1 NET+) allow customers to serve both local and global PA systems if desired, with the option to target and prioritise pages and other audio events across many zones. This flexibility ensures that Stewart Audio customers can address larger facility needs while filling the void of local amplification requirements.

“To date, the market has lacked an affordable way to position networked amplifiers at endpoints,” said Brian McCormick, chief marketing officer, Stewart Audio. “Our new family of compact amplifiers create a cost-efficient way to run CAT5 or CAT6 cable to local zones, allowing our customers to enjoy the benefits of digital audio networking beyond the central infrastructure. These products give our customers a simple and affordable way to address a broad range of low power, low channel count applications without the expense of larger networked amplifiers or the complexity of architecting custom solutions with bridge devices and analogue amplifiers.”

Stewart Audio incorporates the Dante media networking solution from Audinate into its product architecture to enable many operational benefits, while Symetrix Composer 2.0 software facilitates simplification of installations.

The complete range of new Stewart Audio networked amplification solutions include: the AV25-2 NET+:  A 2x25W 4 or 8 ohm low impedance amplifier with two analogue and two Dante inputs, and remote and local volume control.  Automated port switching can override audio feeds depending on which Dante or analog feed is set to priority; AV25-2 NET:  a digital-only version of the AV25-2 NET+ with two Dante inputs; the CVA50-1 NET+: a 50W, 70/100V mono amplifier with one analogue and one Dante input, remote and local volume control, and automated priority port switching to insert local audio feeds over main programmes; and CVA50-1 NET: a digital-only version of the CVA50-1 NET+ with a single Dante input.

All four compact solutions can be pole-mounted or attached to a flat surface near loudspeakers and are plenum-rated to reduce the installation costs associated with rack-mounted systems. However, the 1/3RU design enables simple integration into central equipment racks if desired.
