# RGB mux diagram

Prepare the mux diagram. If you are building your own circuit, this diagram should help.

# Performing the mod

# Step 1: Remove the following components

Remove R1123, R1128 and R133

# Step 2: Add a diode to blanking

Blanking diode added. Helps reduce interference. This mod was performed without shielded cables internally and absolutely no interference was noticed.

# Step 3: Connect RGB and blanking wires

# Step 4: Connect audio and sync wires

# Step 5: Build your mux circuit

This mod uses the RGB mux board. This is optional, but will make your mod easier and stable. You can also create the circuit presented in the schematics above without the board. Please also checkout the mux calculatoropen in new window to play with your own values.
