Video Correction for Pinnacle Studio MP10
Published in issue 290, July 2000
The Pinnacle Studio MP10 is an external real-time MPEG1 codec that includes composite video input and output. The output provides only 0.7 V, which is too low for most video equipment. Many video inputs are standardised for 1-V signals. The low output level of the MP10 can easily be corrected. The correction circuit, with its own small power supply, can also be used for many other applications.
Resistors: R1,R4,R7 = 75Ω R2,R5 = 560Ω R3,R6 = 1kΩ2 R8 = 6kΩ8 P1,P2 = 250Ω preset Capacitors: C1,C2 = 47µF 25V radial C3,C4,C7-C10 = 100nF ceramic C5,C6 = 4µF7 63V radial C11,C12 = 100µF 40V radial C13-C16 = 22nF ceramic Inductors: L1,L2 = 47µH Semiconductors: D1 = high-efficiency LED B1 = B80C1500 (80V piv, 1.5A peak) rectangular case IC1 = AD828AN (Analog Devices) (Farnell) IC2 = 78L06 IC3 = 79L05 Miscellaneous: K1,K2,K3 = cinch sockets, PCB mount (e.g., Monacor/Monarch type T-709G) K4 = 2-way PCB terminal block, raster 7.5 mm Tr1 = mains transformer, PCB mount, secondary 2x9 V/1.5 VA (e.g. Monacor/Monarch type VTR-1209)
