Product Q & A
Review
1, the board uses a new original BB's top volume control chip PGA2311, internal use pure resistor network, the following does not start at 0dB internal amplifier at> 0dB when, using the internal amplifier is a good indicator of the preceding stage. The board is set to -95dB to + 31dB, stepping 1dB;
2, dualAC8-12V power, full use of ON regulator, MC7805 digital part by an independent power supply, minimum disruption. According to the requirements of PDF, analog and digital power supply portion of the main chip has decoupling capacitors Philips 104, take reasonable line, which is one of the advantages of this board is different from the common market products;
3, the digital drive and relay drivers are using a dedicated chip, more professional;
4, STC15 MCU, stable and efficient, stronger anti-interference performance, all states have the power and memory;
5, 4 way audio input with a new imported Matsushita TQ2 relay (better than homemade HUIKE N times, which is one of the selling points of the plate), the signal loss to a minimum.
6, external control switching signals with optocoupler isolation, (optional external power switch board to achieve power switch);
7, small code switch board and the display panel can be separated (connected by double-headed line), and the display panel can be together (without connections), very flexible;
Size: Dashboard (including small coding switch plate) 100mm * 32mm, motherboard 68mm * 68mm.
8, standard high-grade aluminum remote control, press and continuously adjust the volume;
9, standard Taiwanese skillet coding switch, easy to install;
Instructions:
Coding switch: rotate left and right to adjust the volume;
Tap input switching, long press 3 seconds after release the power switch, press and release after 10 seconds to restore the factory settings, tap turned off at boot.
Remote control: V + - to adjust the volume;
CH + - is the input switching;
Power is the power switch;
DSP is to show the current input state;
MUTE muted.
Display Description:
The board is based on the amount of attenuation volume display to display, such as -50 attenuation is 50dB; 0 is no attenuation that is straight; 10 is an enlarged 10dB.
Input status display CH1 CH2CH3 CH4
