![]() ![]() Be confident that no matter your source the Fiera4 can make it sing!Ĭombining the high efficiency of class D and the warm sound of class AB amplifiers, the Fiera4 also offers the flexibility of 4-channel or bridged 2 or 3-channel operation. The Fiera4 supports both balanced and unbalanced sources. As Greg Mackie was fond of saying, “Those who tool, rule!” – make your own and you get exactly what you want every time. We can use common screws throughout and place them screws where they are easiest/best looking and manage our thermals based upon where WE want the heat to go, etc. There’s no need to figure out how to integrate, change our mechanicals to support another design, etc. In summary, when you do your own, you get your own, and it fills all needs you want. Input functionality – we don’t need an adapter board for converting between balanced/unbalanced, we can do that on the main amp board where signals are better buffered and post-switch traces are kept short. You don’t have to put your speaker between a pair of positive terminals – ever! YOU decide if it’s a 2/3/4 channel amp, flip the bridging switches as needed, and ALWAYS connect the speakers to a positive and negative binding post. We also can get the BEHAVIOR we want! Check out how it bridges – unlike anyone else. Why do we want 21.5? It’s a happy compromise between professional audio/installed (big ticket) home theater, and traditional consumer home audio levels. We have 21.5 dB of gain in our module most off the shelf modules are 26, and thus we’d have to add a preamplifier circuit in front, to cut 4.5 dB of gain. But when you can design your own, you get what you want.įor example, look at the way we implement gain. It’s a very complex process, which is why nearly everyone else uses off the shelf modules. Designing and building class D amplifiers is NOT an easy thing to do. Why did we design our own amplification module? Because we get exactly what WE want, and we can. Fiera4 is an ideal combination of value and performance. Implementing the high efficiency of class D with all circuits supporting maximum sound quality, the Fiera4 also offers the flexibility of 4-channel or bridged 2 or 3-channel operation. NS600 Moduleįor true audiophile performance, Starke Sound’s electronics team developed the new NS600 amp module. ![]() We designed it to provide as much power as we need, and deliver 100% of that power at all times, without brownouts or without high idling losses. The amplification modules and SMPS boards are physically separate so there is no shared ground plane, which keeps noise down even further. We tuned the switching frequency to not be an even multiple of the main class D switching frequencies until several hundred MHz. Developing our own and thinking about the mechanicals at the very beginning simplified the entire process, even down to how the SMPS and the amplifiers are connected – we placed the connectors so that we have the shortest interconnects possible. The physical size – including heat and EMI shielding – was set to match our ID and manufacturing systems so we could get exactly the final look we wanted. Why did we make this change? We wanted control over the physical size, the switching frequency, and power output envelope to precisely match what we needed to make the Fiera4 great. Starke has developed a new power supply for the Fiera4. Upgraded NS600 Amplification module with an extensively redesigned front end.A newly designed, highly efficient, switching power supply.A number of enhancements have been made to create our best sounding and performing 4 channel amplifier ever! The Fiera4 is the evolution of our wildly successful AD4. What is New in the Generation 2 Fiera4 Amplifier? Welcome to flexibility, substantial power, great value: Fiera4. ![]() Add height channels for an immersive rig, or power an audiophile 2-channel music system. Upgrade the sound of your audio-video receiver, driving left, center and right speakers. It is a unique 4-channel amp that can be bridged for 2 or 3-channel operation using simple switches on the rear panel. Our ongoing pursuit of better sound quality led to the 2nd-generation, Class D, Fiera4 with proprietary power and amplifier modules. ![]()
