# PDB182-K230K-104A (Component) ## Description Stereo Active Baxandall Bass Shelf EQ using NE5532 Op-Amp and Bourns PDB182-K230K-104A Dual-Gang Potentiometer ## Component Details - **Owner:** jecstronic - **Created:** 10/29/2023 - **Last Updated:** 10/29/2023 - **Visibility:** Public - **System Architecture:** graph LR subgraph Power Rails VCC --> C_dec_pos[0.1uF Decoupling] -VCC --> C_dec_neg[0.1uF Decoupling] C_dec_pos --> U1.+VCC C_dec_neg --> U1.-VCC GND --> U1.GND end IN_L --> C_in_L[Input Coupling Cap] IN_R --> C_in_R[Input Coupling Cap] C_in_L --> RC_L[Left RC Network] C_in_R --> RC_R[Right RC Network] subgraph Pot R1_CCW & R1_WIPER & R1_CW & R2_CCW & R2_COM & R2_CW end RC_L --> U1.+1IN RC_R --> U1.+2IN U1.1OUT --> C_out_L[Output Coupling Cap] --> OUT_L U1.2OUT --> C_out_R[Output Coupling Cap] --> OUT_R Pot -- controls --> RC_L Pot -- controls --> RC_R - **Part Type:** Variable Resistor - **Placement Notes:** Potentiometer (Bourns PDB182 dual-gang) must be placed at the board edge so the shaft exits perpendicular to the front panel. NE5532 supply decoupling capacitors (C1/C2 for +VCC, C9 and local -VCC decouplers) should be placed as close as possible to U1 power pins (+VCC, -VCC) with short, wide traces to the power and ground nets. Input/output audio jacks or headers (IN_L/IN_R/OUT_L/OUT_R) must be placed so connectors are accessible from the panel/edge and spaced sufficiently to avoid mechanical interference between plug bodies. - **Domain:** Consumer Electronics - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Bourns Inc. - **Human Interface:** Switches - **Datasheet URL:** https://www.bourns.com/docs/Product-Datasheets/PDB18.pdf - **Manufacturer Part Number:** PDB182-K230K-104A - **Used in:** 33 projects - **Forks:** 1 ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
