The Starke Sound Fiera8
Our ongoing pursuit of better sound quality led to the 2nd-generation, Class D, Fiera8 with proprietary power and amplifier modules. Upgrade the sound of your audio-video receiver, driving a complete 7 channel system. Or use 2 Fiera8 amplifiers to power a full 9.x.6 system. Welcome to flexibility, substantial power, great value: Fiera8.
What is New in the Generation 2 Fiera8 Amplifier?
The Fiera8 is the expanded version of our wildly popular Fiera4. A number of enhancements have been made to create our best sounding and performing 8 channel amplifier ever!
These enhancements include:
- A newly designed, highly efficient, switching power supply
- Upgraded NS600 Amplification module with an extensively redesigned front end
- Improved Chassis
- Improved Internal Shielding
- Improved Wiring Paths
Shielded Switching Power Supply (SAPS)
Starke has developed a new power supply for the Fiera8. 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 Fiera8 great.
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. 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.
We tuned the switching frequency to not be an even multiple of the main class D switching frequencies until several hundred MHz. The amplification modules and SMPS boards are physically separate so there is no shared ground plane, which keeps noise down even further.
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.
For true audiophile performance, Starke Sound’s electronics team developed the new NS600 amp module. Implementing the high efficiency of class D with all circuits supporting maximum sound quality, the Fiera8 offers 8 channels of outstanding amplification. Fiera8 is an ideal combination of value and performance.
Why did we design our own amplification module? Because we get exactly what WE want, and we can. Designing and building class D amplifiers is NOT an easy thing to do. It’s a very complex process, which is why nearly everyone else uses off the shelf modules. But when you can design your own, you get what you want.
For example, look at the way we implement gain. 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. 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.
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.
In summary, when you do your own, you get your own, and it fills all needs you want. There’s no need to figure out how to integrate, change our mechanicals to support another design, etc. 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. As Greg Mackie was fond of saying, “Those who tool, rule!” – make your own and you get exactly what you want every time.
Chassis Mounted XLR and RCA Connections
The Fiera8 supports both balanced and unbalanced sources. Be confident that no matter your source the Fiera8 can make it sing!
Combining the high efficiency of class D and the warm sound of class AB amplifiers, the Fiera8 powers up to 8 speakers for ultimate flexability.
