Built for the install, not the spec sheet
Two Steps Above.
The Z-AT Series sits at the top of Zapco's competition amplifier line — an evolution of the successful AP platform developed for competitors pursuing the highest levels of sound quality performance.
The AP Series established itself as one of Zapco's most successful sound quality amplifier platforms, earning recognition in competition vehicles around the world. Rather than replacing that success, the Z-AT Series builds upon it. Drawing from years of competition experience, Zapco refined an already proven platform with upgraded components, increased power, enhanced voltage regulation, more precise bias adjustment, and expanded system flexibility. The result is an amplifier designed for competitors who are always looking for the next improvement—because great products don't stand still.
350 Watts × 2 of Class AB Power
The Z-350.2 AT produces 350 watts per channel at 4 ohms and 600 watts per channel at 2 ohms, giving the system designer substantial amplifier reserve from a two-channel chassis.
That output makes the Z-350.2 AT particularly useful for demanding front-stage applications where each channel needs significant power. It can also be bridged to produce 1,200 watts at 4 ohms when the system architecture calls for a single higher-power channel.
Increased Headroom for Active Systems
The additional power provides increased headroom, giving the amplifier greater reserve for demanding DSP-based systems and complex musical content. That additional margin allows the amplifier to operate further from its maximum output, helping maintain consistent performance when the system demands it most.
System Application
The Z-350.2 AT is well suited to high-performance front stages where substantial power is required across two channels.
It can drive a stereo pair of midbass or midrange drivers, provide dedicated amplification for a pair of full-range component channels, or be bridged when the system design calls for a higher-power single channel.
The shared AP/Z-AT chassis dimensions also make it easy to incorporate the Z-350.2 AT alongside other Zapco amplifiers.
HF Audio Perspective
The Z-350.2 AT is a good example of why amplifier selection should follow system design.
Two channels may be the right architecture for one build, while another may benefit from dedicated mono amplifiers for individual drivers. The Z-350.2 AT gives the builder substantial power while keeping two channels together in one compact chassis.
For systems that need that combination of power, Class AB architecture, and two-channel flexibility, the Z-350.2 AT fits the role without requiring the system to be built around the amplifier.
