 Helium has three independent buffered multiples that each have three outputs. These are also called *unity gain buffers*.

+![Illustration of using Helium's three channels independently](images/three-channel.png){: .dark-invert}
 
 Each channel's input is on the top left and the three buffered outputs follow on the right and below. The LEDs for each channel will glow blue for positive signals, red for negative signals, and purple for audio signals.
 
 Additionally, the inputs for channel two and three are chained so if nothing is connected to the input then the input of the preceding channel is used. This allows you to use Helium to buffer a single signal to up to nine outputs.

 ## Using the precision adder
 
 Helium has a precision adder with three inputs and one output. It sums the three inputs into a single output and works equally well for CV and audio signals. Precision adders are also called *unity gain mixers*.

+![Illustration of using Helium as a precision adder](images/adder.png)
 
 The inputs are the top two and bottom left jacks (shown in teal, purple, and red) while the output is the bottom right jack (shown in yellow). Unconnected inputs do not affect the output. Just like with the buffered multiple channels, The LED in the middle will glow blue for positive signals, red for negative signals, and purple for audio signals (it's shown in yellow above for illustrative purposes).

 Your first task is to place and solder the power header to the mainboard.

 Place the power header onto the back side of the mainboard, being careful to align the notch in the header with the drawing on the board. The power header fits snugly, so you might have to give it a little pressure to push it all the way in.

 ## Placing the jacks
 
 Next up is placing the sixteen jacks on the front side of the mainboard. Start by placing the first jack on in the space labeled `In A`. Place it according to the drawing on the board, with the third, bendy leg going into the adjacent hole.

 The second jack is a bit trickier. Place it into the space labeld `Out A2` but in the **opposite** orientation of the first jack. Place the third leg into the **same** hole as the first jack's third leg.

 Continue this pattern for the third and fourth jacks in the spaces labeled `In B` and `Out B2`. The third and fourth jacks will have their third legs placed into the same hole.

 ## Using the front panel as a jig
 
 Since the jacks need to peek through the front panel, you can use it as a jig to make sure everything stays in the right place while soldering. Carefully line up the front panel's holes with the jacks and push the front panel on.
 
-![The front panel placed over the jacks](/images/10-panel-align-1.jpg)
+![The front panel placed over the jacks](images/10-panel-align-1.jpg)
 
 Then, use the two rubber bands to temporarily hold the front panel on while you're working on it. You'll need to double- or triple- over the rubber band to get it tight.

 Put the two rubber bands on opposite sides of the module so that everything is held down snugly.

 ## Soldering the jacks
 
 With everything held in place, you can now flip the module over and solder all of the jacks in place. As you go, take a moment now and then to check that everything is flush with the panel and mainboard.

 Once you've got most of the soldering done, you can move the rubber bands out of the way to get to the holes that they were covering up. You won't need the rubber bands again after this step, so feel free to give those a new purpose in life somewhere else.

 ## Putting the panel on
 
 The last step it to place Helium's lovely panel on and secure it with the hex nuts. You don't need to over-tighten the hex nuts, finger-tight is fine.
