This is the bundle including the bare boards for Simpelstark+ amplifier and Compact PSU, 2 boards each (dual mono configuration for the lowest noise and crosstalk), plus our latest Amp Control System 6.2.2 boards set.
Simpelstark amplifier opens our Delicate Sound amplifiers family.
A specialty of this design is high linearity of every stage and low amount of global negative feedback - only 18db of ODNF error correction. The amp is particularly good for acoustic music - jazz, classics, guitars, vocals, drums, cymbals, etc.
The amplifier is dead silent at idle, which is a big advantage for listening at the low volumes and/or with some high-sensitivity speakers.
If you order the boards we provide all necessary documentation and of course - our support for the build.
Key specifications with +/-50V rails:
- Maximum output power: 100W @ 8 ohm; 160W @ 4 ohm
- Voltage gain 29db
- Input impedance 47 Kohm
- THD: 1KHz - 0.007%, 10KHz - 0.05%, 20KHz - 0.07% (measured at 50W @ 8 ohm)
- IMD: 14+15KHz - 0.007% (measured at 50W @ 8 ohm)
- SNR: 117db
The board dimensions: 180 x 100 mm
Unregulated PSU board with SS relays on the rails (controlled by the Amp Control Board 6.2.2).
Dimensions: 100 x 100 mm.
Amp Control boards set V6.2.2 includes the following PCBs:
- 1 x Amp Control board V6.2.2 PCB
- 2 x DC Offset Detect module PCBs (SMD or TH)
- 2 x Temperature Sensing module PCBs
Amp Control V6.2.2 is a microprocessor controlled monitoring board that will shut down the amplifier, sending a signal to disconnect the speakers on any sign of a problem from the amplifier it is connected to.
