VU meter circuit left and right channel as the second section consists of circuits 6 10 s LED display used ultimately each display 10 LEDs where the per channel 60 LEDs are used a total of 120 LEDs at the same time per channel 6 LM3914 is used to integrate a one synchronous with the works, but located on the first audio signal entering the circuit 1k (application used 3.3K) by measuring with a multimeter necessary to adjust potentiometers
Calibration; The first section 20 mV, 150 mV 10 Chapter 20 Section 300 mV and 900 mv…………. 60 Section
Pcb design made with sprint layout of the circuit. Layer PCBs have drawings of extension resources.

Opamp und Transistor-Schaltungen sind sehr schöne Qualität Kopfhörer-Verstärker-Design-Qualität für diese Schaltung hat auch eine symmetrische Stromversorgungsschaltung. Design der gedruckten Schaltung ganz gut, vor allem die verwendeten Materialien, die Kosten für fast einen Hochleistungsverstärker, aber die Preise auf den Namen Hi-Fi :)
