For our project we are looking for advice on the Tripath TA2020 or TA2040 based Class-D amplifier chip. (Note that Tripath went tits as a business for some time, but the charges of their chips are still available. Tripath called implementation of the architecture of D “Class T”, which clouded the water a bit, but basically they were incredibly good class D chips, which covered a wide range of energy needs.) Both chips are quite similar, but takes a little more power TA2020.
This is a do-it-yourself DIY version of the response time ProAc 2.5, which is one of the most famous of the speaker in his class of about 1996 to 2003. This model was replaced by a new model in 2003 called the reaction D25 replaced by units of the pilot was, but always in the same way two floostanding concept. 2.5 The response is considered one of the most successful and famous ProAc and is a testament to the skill and the expression of their ProAc designer Stewart Tyler.
Build a Subwoofer Box Program with Design Toolbox, AJ Audio Design Software and Box Designer Gold Edition
Subwoofers are specialized in sound frequency, which lower, such as bass.
The design of a subwoofer is important to always have the best sound quality. While you can buy a subwoofer, and install it in your sub, the housing may not be as good as you can design be acquired. Several variable factors in the creation of a forum for high-quality sub – the material used, the volume of the housing, and even the length-width makes a difference. Several programs are available to help you find your own housing.
The project PCM2704 USB DAC sound card is fully functional for the PC sound card. The main advantage of using PCM2704 PCM2702 is against the construction much easier. As seen from the diagram that he in 5V and 3.3V voltage regulator, HID interface (MUTE, VOL +, VOL-), S / PDIF output. Joined see The circuit can be directly from the USB port power. Next advantage is that the DAC output can directly drive 32 Ohm headphones, but the performance is only 12mW. For full details please refer to the PCM2704 datasheet.
The program is very simple. It is almost a copy of the chart sheet. You can see the core IC PCM2704 (U1), the crystal with documents (X1, C1, C2, R1), the connection to the USB port (USB port, R2, R3, R4, L1), a large number of blocking capacitors for all voltages (C3, C4, C5, C6, C7, C8), head of the S / PDIF output (J1), HID-header (J2), the output of the filter (R5, C11, R6, C12, R7, R8), coupling capacitors (C9, C10) and the output 3.5 mm jack connector (J3).
