This product complements the  KTR-4000 MASTER BOARD. It allows 4 VCAs to be connected in parallel to reduce noise and THD in the signal path and enhance the performance of the main VCA. It consists of a high-quality double-sided plated-through-hole PCB (Lead-free HASL) with solder mask on both sides and full screen print. The PCB dimensions are 59mm by 28mm and include 7 mounting and interconnection holes, compatible with dbx 202 / 202C / 202X–type VCA module formats.
The following diagram illustrates the interconnection among various boards designed by Olas Audio, forming the Mix Bus Compressor.

Building Olas Audio’s professional Mix Bus Compressor requires interconnecting multiple boards, including components like the Gain Reduction Meter and switches on the CTRL-PANL, AUTO-FADE, and TURBO-MODE boards.
The published price is for the PCB only. A bill of materials and assembly instructions will be provided upon purchase.
