Bus Board (4ms Bus Stick or other passive distribution board) 

Any passive power distribution board can be used with the 

Row Power 25

. If the bus board connects 

to the power supply with a standard 16-pin Eurorack power cable, then simply use the male pin power 
connector on the back of the 

Row Power 25 

to connect to the bus board. Verify the red stripe is 

pointed down on both ends of the cable. An example using the 4ms Bus Stick is shown below.

The Bus Stick can be secured to the case using the adhesive pads on the back. Make sure the surface 

is clean and apply pressure for 20 seconds. It’s safe to daisy-chain a flying bus cable or another Bus 

Stick, but to insure the lowest noise system, use as few connectors as possible.

Solder connectors 

The 

Row Power 25

 has a set of four holes for +12V, -12V, +5V, and ground. The holes are 

0.082” (2.1mm) in diameter and are spaced 0.156” (3.96mm). They fit the Molex MTA156 connector 

(example: Molex PN: 5273-04A or 09652048). They also will fit 14 AWG wire.

These connectors are provided for advanced users with sufficient knowledge of soldering and power 

systems. They can be used with a custom or specialized low-noise bus board system. While 4ms 
Company will warranty and support the internal circuitry of the 

Row Power 25

, we do not offer 

support for 3rd party or DIY bus boards or distribution systems.
