Горячие продажи 8-параллельного TDA1387, замена коаксиального волокна TDA1541

latest arrival 8 parallel TDA1387 replacement TDA1541coaxial fiber USB DAC decoder discrete resistance and capacitance

This machine adopts the classic: CS8416 SAA7220 TDA1387 8 parallel NE5532 PCM2704 scheme

Our shop specially introduced an alternative solution, using TDA1387 8 in parallel to replace TDA1541, the quantification effect is about 90% of TDA1541 after testing.

Buyers can also directly upgrade to TDA1541, just plug and replace the IC.

【Design Features:】

1: Adopt dual AC15 dual AC9 independent power supply. Improve the separation and mutual interference of the whole machine, and the whole machine works more stably. Guarantee its big scene music dynamics and speed.

The transformer is divided into two 10W 12W, which are made of oxygen-free copper wire Japanese Z11 silicon steel sheet. The intermediate frequency is thick and dense, and the sound is warm. The effect is better than that of Huanniu.

.

2: The circuit layout adopts the classic one-point grounding, the layout is reasonable, the installation is convenient, and the mechanical strength is high.

3: SAA7220 is used as a digital filter, and it is matched with TDA1387 (can replace TDA1541) to form a seamless graft. It works at 4X oversampling, and uses the powerful CS8416 for digital reception.

4: Support multi-signal access, including coaxial, USB, optical fiber, compatible with the current maximum 44.1K sampling rate and other audio files.

5: USB decoding adopts the best decoding chip of TI company: PCM2704, so that users on the pc end can enjoy better music.

6: The whole machine uses regular channels to purchase audio fever components, such as Nichicon, Siemens, Thomson, Nippon Chemical and other audio capacitors. Through careful matching, the characteristics of TDA1541 can be maximized.

7: Board size: 140*100, using high-quality board: FR-4

8: All discrete RC parts have higher precision and higher stability than SMD RC parts.

9: The weight of the whole machine is 1.8 kg, the width is 318, the depth is 220, and the height is 70 (the height of the panel is 70, and the height of the iron box is 60)

10: Mango wood solid wood panel, rich texture, 1MM thick sturdy iron chassis, good anti-electromagnetic interference effect.

11. The interface terminals are nickel-plated copper, the signal selection knob is a solid aluminum knob, and the power button is a solid wood button.
