4.2.1All Channel Shutdown

System comes up with all channel shut down asserted.

To exit All Channel Shutdown, select Setup Tab, unselect All Channel Shutdown.

4.2.2Advanced Features : EQ and DRC

EQ and DRC can be designed in ALE (Automatic Loudspeaker Equalization tool).See the EQ/DRC Tool Installation section that appears later in this document. The filters designed in ALE can be saved into a file. Load the ALE output using File -> Load the ALE File and select the ALE output file . Select Autobank switch ON in the EQ tab. The EQ and DRC parameters can be viewed by selecting the EQ viewer or DRC tabs. Coefficients are loaded into DAP in the autobank switch only when a legitimate sample rate is applied. EQ and DRC are loaded before the step described in Section 4.2.1.

4.2.2.1EQ Loading and Viewing

EQ coefficients can be generated using ALE. (See ALE User's Guide.) Once EQ coefficients are generated, they can be loaded into the part using FileLoad ALE using the TAS570x GUI.

4.2.2.2DRC Coefficient Loading

DRC coefficients can be generated using ALE and can be loaded using FileLoad ALE. Normally, both EQ and DRC coefficients are created and saved as a single file from ALE. DRC1 (satellite channels) and DRC2 (subchannel) can be enabled and disabled using the toggle button in this tab.

TAS5601 specifications

The Texas Instruments TAS5601 is a high-performance class D audio amplifier designed for various audio applications, ranging from home audio systems to professional audio equipment. This device is particularly renowned for its efficiency, sound quality, and compact design. The TAS5601 is specifically engineered to drive passive and active speakers, allowing users to achieve high power output and excellent sound fidelity.

One of the key features of the TAS5601 is its ability to deliver up to 50 watts of output power per channel, making it suitable for driving demanding loads. It operates within a supply voltage range of 15V to 30V, allowing for flexibility in various application environments. The amplifier’s efficiency is a significant advantage as it minimizes heat generation, enabling cooler operation and reducing the need for extensive thermal management solutions.

Technology-wise, the TAS5601 employs a proprietary, high-resolution pulse-width modulation (PWM) technique. This methodology ensures excellent linearity and low total harmonic distortion, translating into crystal-clear audio reproduction. The device also utilizes a robust feedback mechanism that adjusts the output in real time, further improving sound quality under varying load conditions.

The TAS5601 features integrated protections for over-current, over-temperature, and short-circuit scenarios, ensuring reliable performance and longevity. This makes it an excellent choice for both commercial and consumer audio products.

Another notable characteristic is the inclusion of an I2C interface, which offers enhanced programmability and flexibility. With this feature, designers can configure settings such as gain controls and filters, thus optimizing the amplifier for specific applications and listener preferences.

The TAS5601 supports multiple speaker configurations, including a dual-channel operation in a stereo setup or bridging mode for higher output in mono applications. It is designed to work seamlessly with various digital audio sources, allowing for versatility in integration with modern audio systems.

With its advanced features, state-of-the-art technologies, and robust performance, the Texas Instruments TAS5601 is a leading choice for audio amplification. Whether for home theater systems, portable speakers, or professional audio installations, the TAS5601 delivers exceptional sound quality while being energy efficient and adaptable to a wide range of needs.
