Product Description:
This Power Amplifier boasts a number of features that ensure high-quality sound and user-friendly operation:
- Built with the original TDA7498 QCC3008 Bluetooth 5.0 module.
- Features a power filter capacitor with a capacity of 1800UF / 35V capacity.
- Implements a German grade WIMA electrodeless capacitor, enhancing sound transparency.
- Consists of high-precision chip resistors, maintaining a good signal-to-noise ratio.
- The 1.6mm thick double-sided PCB board with 2.0-ounce copper thickness facilitates a full tin-spraying process, ensuring excellent passing performance of both large and small currents.
- Facilitates sound clarity and power with a special power discharge sense of red and gray rings.
- Connects to Bluetooth in the same manner as most devices.
Input modes include both analog and Bluetooth. However, in case both are active simultaneously, the Bluetooth input has priority. When connected to Bluetooth, the RCA input will automatically disconnect, hence requiring the user to switch off the Bluetooth function on the mobile phone whenever analog input is needed.
The working method of the device is class D, with a quiescent current of 50mA and a work efficiency rate of 90%. Rated output power is 2 x 100W, and the frequency response ranges from 20Hz to 20KHz. It operates within a voltage range of DC20V to DC32V, however, DC24V is recommended. The maximum output current is 3A.
The amplifier measures 135 x 90 x 39MM (excluding wire height), while the antenna length is 103MM.
The package includes:
1 x Power Amplifier (Power supply not included)
