	P7-MINI Preamplifier Board Top Pre-AMP Headphone Amp Kit
	
	
	
	Features:
	- This is a well made pre amp board, full DC,no coupling, simple, while sophisticated.
	- Avoid any distortion caused by capacitors. And bandwidth limitations.
	- Frequency to DC 1HZ, high to 1M HZ.
	- Using double-sided gold-plated military grade PCB material.
	- Previous level can be better with MX50, L20, L6 and other power amplifier boards.
	- Cable can be easier ways to avoid the wrong signal line connections for a variety of noise problems.
	- Not recommended after amplification with the use of DC power amp board.
	- Low-noise, four times the amplification. Using AC 12-0-12 V power supply.
	- NCC series using the maximum filter capacitor. KZE ULTRA LOW ESR capacitors.
	- TDK monolithic decoupling capacitors. Taiwan Stepping low error potentiometer.
	- JRC 4580 D op amp (you can replace it with NE5532)
	- Low-noise dual op amp.
	- PCB area of 2.8 CM * 7 CM
