The Starke Sound Fiera4

Our ongoing pursuit of better sound quality led to the 2nd-generation, Class D, Fiera4 with proprietary power and amplifier modules. This unique 4-channel amp can be bridged for 2 or 3-channel operation using simple switches on the rear panel. Upgrade the sound of your audio-video receiver, driving left, center, and right speakers. Add height channels for an immersive rig or power an audiophile 2-channel music system. Welcome to flexibility, substantial power, and great value: Fiera4.

What is New in the Generation 2 Fiera4 Amplifier?

The Fiera4 is the evolution of our successful AD4, now featuring several enhancements for the best sound and performance:

• Newly designed, efficient switching power supply
• Upgraded NS600 Amplification module with redesigned front end
• Improved chassis, internal shielding, and wiring paths

Shielded Switching Power Supply (SAPS)

We developed a new power supply for the Fiera4 to match our design needs, enabling control over size, switching frequency, and power output. This optimization reduces noise and ensures consistent power delivery without brownouts or high idling losses.

NS600 Module

The Fiera4 offers the high efficiency of class D, along with the flexibility of 4-channel or bridged operation. It has been optimized for 21.5 dB of gain for professional audio and home theater applications.

Chassis Mounted XLR and RCA Connections

The Fiera4 supports both balanced and unbalanced sources, ensuring compatibility with any setup.

Multichannel Flexibility

With its unique combination of class D efficiency and warm class AB sound, the Fiera4 is highly versatile, adaptable for 4-channel or bridged 2- or 3-channel setups.

Unique Designs Unique to Starke Sound

Starke Sound’s extensive engineering, led by Dan Wiggins, delivers innovative amplification technology found only in the Fiera4.
