Completed amphitheater project. In the amplifier circuit, STK428-610 integrated preanf circuit in PT2317B ( digital control ) and designed with a TOP249Y power source for all parts of the SMPS circuit is used, SMPS power transformer ETD39 ( SMPS transformer windings information page 34 … 39 ). Because the driver in the TOP249Y houses MOSFET, SMPS circuit is prepared with very little material. It is prepared with the SMPS design PI Expert program.
TOP249Y ANFI SMPS SCHEMATIC
In addition, you can use the preanfital and SMPS circuitry in different projects, as you have to examine the datasheet files that fit within the different STK amp integrals of the PCB drawing prepared for the amphitheater, which is compatible with a lot of the leg connections of many STK series ancillary integrations.

The PT2317B integration on the preamplifier circuit used in the amphibious project requires a very talented little material. It is mostly used for auto tapes. It can be used in 2 channels with integrated 4 channel output, bass, treble, balance, fader, and loudness controls.
PT2317B CIRCUIT SCHEMATIC
You can use an amphitheater, SMPS, and tone control circuits for very different projects, especially if it is a quality amp project, especially if the circuits have separate print circuits.
PT2317A and PT2317B are four-channel digital audio processors utilizing CMOS Technology specially designed for car audio and hi-fi systems. Volume, Right/Left Balance, Bass, Treble, Fader, and Loudness Functions are incorporated into a single chip Selectable gain, direct key mode, as well as LED indicator for every function, are also provided to build a highly effective electronic audio processor having the highest performance and reliability with the least external components. Pin assignments and application circuits are optimized for easy PCB Layout and cost-saving benefits.
