## Electrical Design
|
||||
This chapter contains some notes on the electrical design.
|
||||
Currently just the sources of the used circuit designs.
|
||||
|
||||

|
||||
### Microphone Input
|
||||
#### Preamplifier
|
||||
For the microphone preamp, we are using the NE5534 low-noise opamp with a circuit design from [circuitlib microphone pre-amp](https://www.circuitlib.com/index.php/schematics/product/29-balanced-microphone-preamplifier).
|
||||
|
||||
##### Controllable Amplification
|
||||
#### Controllable Amplification
|
||||
In a normal mixer, you would be able to lower the microphone's volume to zero.
|
||||
But in our case we just need on/ off and some gain range to adjust for different microphones and loudness of different people.

#### Line Input/ Input Module
|
||||
|
||||
### Line Input/ Input Module
|
||||
The line input must not be amplified at all, because loudness control of the headphones is done by the headphone amplifier section.
|
||||
But the differential line-level signal must be converted to a single-ended signal by the input stage.

#### Summing
|
||||
|
||||
### Summing
|
||||
Summing is needed in two places: Creating the sum of all microphones (not adjustable, fixed output gain) and for the headphone mix (one input level adjustable).
|
||||
A simple summing circuit using one operational amplifier is enough for our application, like in [circuitlib audio mixer tutorial](https://www.circuitlib.com/index.php/tutorials/product/39-how-to-build-an-audio-mixer).

|

Because the stage input is quite independent of the interpreter's microphones, no special phase/ inversion considerations are needed.
|
||||
And the microphones connected to our unit will experience the same inversions anyways.
|
||||
|
||||
#### Line Output Driver
|
||||
|
||||
### Line Output Driver
|
||||
Line Output conversion is done by the [DRV134](https://www.ti.com/product/DRV134) IC.

|

|
||||
#### Headphone Output Driver
|
||||
|
||||
### Headphone Output Driver
|
||||
The headphone output needs a maximum output power of about 0.1 W and should put the mono signal on both stereo channels of the TRS jack.
|
||||
|
||||
For the first draft, we're using one LM386 audio power amplifier even though it has a quite high minimal amplification of factor 20.
|
||||
|
||||
#### VU Meter
|
||||
|
||||
### VU Meter
|
||||
When searching for VU meter circuits, many use the LM3916 LED bar graph driver, which already has the right scaling built in.
|
||||
But this chip is obsolete and not produced any more, so we designed our own chain of comperators to drive a set of LEDs.
|
||||
|
||||
#### User Interface Hardware
|
||||
For the potentiometers, we first wanted to use ones with a conductive plastic resistor element for maximum longevity from Bourns, but these are hard to find with logarithmic scaling.
|
||||
An affordable and easily obtainable (Reichelt) alternative was found in the Alps RK11K and RK14K series.
|
||||
They are available in linear and logarithmic scale, as well as single (mono) and dual (stereo) units and have a nice feeling.
|
||||
|
||||
Another potentiometer from Omeg was tried, but it had a "jump" in the resistor value at some knob positions.
|
||||
|
||||
TODO: On-Air button
|
||||
## User Interface
|
||||
The user interface should enable the interpereters to adjust their microphone gain and headphone mix on their own.
|
||||
Additionally, a (permanent) on/off switch, as well as a (temporary) mute button should be present.
|
||||
|
||||
A possible UI layout might look like this: 
|
||||
|
||||
|
||||
### Potentiometers
|
||||
We need some single and dual channel logarithmic scale potentiometers, which are matching in size, for:
|
||||
- top plate interface (all vertical style, threaded collar would be nice):
|
||||
* 1 single channel for the input gain (resistance doesn't matter)
|
||||
* 2 single and 1 stereo channel for the headphone mix (ideally 50K, b/c 3 will be in parallel)
|
||||
- front plate next to the headset jacks (horizontal style, threaded collar not needed):
|
||||
* 1 single channel for the headphone volume (ideally 50K, b/c that's already tested)
|
||||
|
||||
Possible knobs may be:
|
||||
- (A) Re'an F311/ F313 series (11/ 13 mm diameter) -- 0.40 €/ 0.55 €:
|
||||
Boring: 9.0 mm D-style hole + 0.0 mm nut cover section = 9.0 mm
|
||||
- (B) Re'an P670 series (12 mm diameter/ 16 mm at bottom) (alt. Davies Molding 1101) -- 0.78 €:
|
||||
Boring: 7.5 mm D-style hole + 4.5 mm nut cover section = 12.0 mm
|
||||
Nut cover: 12.9 mm diameter (M7 nut is 12.5 mm corner to corner)
|
||||
- (C) Re'an P300 series (11 mm diameter/ 15 mm at bottom):
|
||||
Boring: 9.0 mm D-style hole + 3.0 mm nut cover section = 12.0 mm
|
||||
Nut cover: ? mm diameter (M7 nut is 12.5 mm corner to corner)
|
||||
- ~~(D) Cliff K87MAR series/ RS Pro 777-73xx: 7.5 mm hole depth + 4.5 mm skirt = 12 mm, inner size of skirt 12 mm (measured)~~
|
||||
~~Notes: D-style boring has wrong size (5 mm instead of 4.5 mm flatted)~~
|
||||
|
||||
Potentiometers from Alps Alpine seem to have a decent quality in a small package size and quite affordable price.
|
||||
From their lineup, the RK09K/D, RK11/12/14, RK09L and RK097 series are left considering our requirements (mouser prices without VAT, shortlist marked bold):

- Input gain:
|
||||
* RK09K1130AJ3 (single, 10K, 15 mm) + Re'an F311/ F313 (diameter TBD)

|
||||
### Switches

|
||||

|
||||
- [Bopla ATPH 1865-0250](https://www.bopla.de/gehaeusetechnik/product/alu-topline/alu-topline-gehaeuse/atph-1865-0250.html) (front might not have enough space for the connectors)
|
||||
- Design our own casing to laser cut/ 3D print
