Among the five satellite boxes of rambler DA5 100, the central satellite box with dual midrange unit layout and the surrounding satellite box with standard layout all adopt dual-frequency division design, and the sound positioning is excellent. The 3/4-inch silk film tweeter has a sweet and soft tone, and the 3-inch high-quality paper basin has a full midrange. In addition, the satellite box is fully enclosed, with pure timbre and clean and clear range, which can truly restore the atmosphere of the scene.
The upgrade is not limited to the upgrade of the audio unit. Rambler DA5 100 not only designed the circuit completely, but also added a more powerful digital power amplifier system based on DSP. Two power amplifier chips TAS5 186 and TAS5342 produced by Texas Instruments are added to the new power amplifier system. TAS5 186 power amplifier chip can provide up to 5 channels of 30W and 1 channel of 60W, and can provide more than 200W in a single integrated device. At the same time, a new pre-charge system is adopted to eliminate switching noise and drive five satellite boxes independently. TAS5342 is a stereo digital power amplifier chip. Under the condition of 10% total harmonic distortion plus noise (THD+N), it can provide the driving capability of 100W per channel for a 4 ohm load, and can be used to drive the subwoofer alone to better control the sound distortion at high volume. Through these two power amplifier chips, high, medium and low frequency signals can be controlled independently, and the signal restoration is quite accurate.
Thank you very much for your concern and support for rambler products!
