This is not only a clone, find something new in the project details. The main circuits are separated to modules, and finally all connected to the one (big) mainboard. The parts of this projects: mainboard, power filters for less noise, the EQ board, Power Supply, and the board for adjustable resistors. Because finally all of the modules are connected, lots of headers on the circuits. These are required for module connections. Look at details on the page of schematics and notes. PCB-s and more notes, pictures, details about this project are available on the author’s blog and websites: P1 4 Footprint Number D Revision A Date: File: 3 Value EQ Module for Parametric Multiband EQ 10/12/2011 Sheet of D:\!Works\..\Multiband EQ 1-panel.SchDocDrawn By: 4 Quantit y Designator 5 6 Model:Footprint Capacitor 100n RAD-0.3 2 C1, C5 Radial Cap, Thru-Hole; 2 Leads; 0.3 in Pin Spacing Capacitor C(a) RAD-0.3 1 C2 Radial Cap, Thru-Hole; 2 Leads; 0.3 in Pin Spacing Capacitor C(c) RAD-0.3 1 C3 Radial Cap, Thru-Hole; 2 Leads; 0.3 in Pin Spacing Capacitor C(b) RAD-0.3 1 C4 High Conductance Fast Diode DO-35 1 D1 Radial Cap, Thru-Hole; 2 Leads; 0.3 in Pin Spacing Diode, Axial; Body 3.8 x 1.9 mm (LxDia. max), Lead Dia. 0.53 mm (max) Header, 6-Pin, Dual row HDR2X6_CEN Resistor 4.7k AXIAL-0.4 2 P1, P2 Connector; Header; 6x2 Position R1, R3, R4, R5, R7, R9, 7 R10 Axial Device, Thru-Hole; 2 Leads; 0.4 in Pin Spacing Resistor 390 AXIAL-0.4 2 R2, R6 Axial Device, Thru-Hole; 2 Leads; 0.4 in Pin Spacing Resistor 2k AXIAL-0.4 1 R8 Axial Device, Thru-Hole; 2 Leads; 0.4 in Pin Spacing Resistor Low-Noise JFET-Input Operational Amplifier 100k AXIAL-0.4 1 R11 Axial Device, Thru-Hole; 2 Leads; 0.4 in Pin Spacing J014 1 U1 DIP; 14 Leads; Row Spacing 7.62 mm; Pitch 2.54 mm RAD-0.2 1 W1 Radial Cap, Thru-Hole; 2 Leads; 0.2 in Pin Spacing Jumper Wire Document last modified and saved: 12 October 2011 6:07 PM  Modular parametric EQ project based on UREI 545 and 546 - 4 5 - Schematic and BOM for the module of Parametric EQ project Schematic of “Adjustable resistors” circuit module 1 2 3 5 P5 R (Band frequency) A 4 1 2 3 4 5 6 P1 Pot stereo Schematic and BOM for the module of Parametric EQ project.

I like to use this simple circuit to filter the problems of power. These circuits have to be connected to the headers P26-P29, and P33-36 on the PCB of 546 clone mainboard. 8 (ot the PCB-V4 6) modules required for better power and less noise, but if you think this is not important, you can wire pin 8 to pin 10 and pin 7 to pin 12 to ignore these circuits and boards. We have two versions of power filter PCB. No difference between schematics, the one of them is landscape, the another one is portrait orientation.

This panel have to be connected to the headers P14...P25. This is 12 connectors, but 6 modules only, because 1 EQ module have 2 headers, look at the PCB of EQ module. Under these modules (on the PCB) have 6 connectors for adjustable resistors. For the EQ modules required 3 resistors/module, adjusting the bandwidth, the frequency, and the cut/ boost, from P1 to P12. And required 3 smallest resistor modules with only one header for low cut filter P13, high cut filter P32, and to adjust the output gain P31. Visit the PCB board about adjustable resistors. The 3th module required for this board is the power filter board. I like to use this simple circuit to filter the problem of power. These circuits have to be connected to the headers P26-P29, and P33-36. These are 8 modules for better power and less noise, but if you think this is not important, you can wire pin 8 to pin 10 and pin 7 to pin 12 to ignore these circuits and boards. Finally in this schematic have connectors for 6 parametric EQ bands instead of 4 (like in the original UREI 546). This is just for fun, you can ignore the last 2 band and boards, but you can build 6 bands parametric EQ instead if 4 just for fun. 6 Document last modified and saved: 12 October 2011 6:07 PM  Modular parametric EQ project based on UREI 545 and 546 - 12 13 - Modular parametric EQ project based on UREI 545 and 546 PCB for the module of Parametric EQ project Top and bottom PCBs and overlay of EQ module TOP LAYER BOTTOM LAYER PCB OVERLAY OVERLAY ON TOP LAYER Printed Circuit Boards for Parametric EQ project U1 C2 R9 R11 R5 C1 R2 R10 R3 C5 12 6 P1 7 1 7 1 12 6 P2 D1 R6 R5 R1 R4 12 6 R10 R7 R8 R1 R4 W1 C3 R6 P2 C1 W1 R2 R3 C5 7 1 D1 12 6 R7 R8 C2 C4 C4 C3 U1 P1 7 1 R9 R11 Document last modified and saved: 12 October 2011 6:07 PM  Modular parametric EQ project based on UREI 545 and 546 - 14 15 - PCB for the module of Parametric EQ project Top and bottom PCBs and overlay of 3 adjustable resistors Modular parametric EQ project based on UREI 545 and 546 PCB for the module of Parametric EQ project Top and bottom PCBs and overlay of 2 adjustable resistors Notes BOTTOM LAYER TOP LAYER BOTTOM LAYER TOP LAYER I made 2 versions of PCB for adjustable resistors, because one of these made for max. 2 (or 1 only) mono and stereo adjustable resistors (for high cut and low cut filters, and for output gain), the another one is made for max. 3 (or 2 or 1) resistors (adjust Freq., Boost, and Q features of EQ).

The benefit of this board the smaller size, and lower final costs.
