R1 1-kΩ fixed 1k resistor brown-black-red  
R2 10-Ω fixed 10-ohm resistor brown-black-black  
R3 1-kΩ fixed 1k resistor brown-black-red This resistor is only used for applications requiring much reduced sensitivity. Otherwise, a jumper wire is used in place of the resistor.

Medium project box

4.875" long x 2.5" wide x 1.5" deep
(12.4x6.4x3.8 cm)

PB-M project box 1    
Project box labels       Stick on labels are provided in strips to identify the components on the project box.  
Template for box lid       A paper template sized for the lid of the project box is provided in order to obtain the correct placement of holes for the components.  
9-V battery holder with hook and loop strips 9BH laydown battery holder 1 9-V battery clips in to this laydown container. The supplied hook and loop strips are used to stick the holder down to the inside of the project box. red wire is positive; black is negative
Toggle switch SW2 Toggle switch 1 On-off switch for power no polarity
Linear-taper potentiometer

LP10k

linear taper pot

Used to adjust sensitivity

 

Pointer knob

PK knob 1 Used as pointer for potentiometer setting  
Panel jack for AC/DC adapter PJ AC/DC jack 1 Receptacle for AC/DC adapter as an alternate power source When the AC/DC adapter is not plugged into the jack, terminals 1 and 2 are shorted internally. This connection opens when the adapter is plugged in. Because of this feature, terminals 2 and 3 are used to supply power from the adapter, while terminals 1 and 2 are used to supply power from the battery. Terminal 2 is shared by the two power sources and is connected to ground.
3.5mm mono panel jack 35MJ 3.5mm mono panel jack 1 Used as a receptacle for the microphone cable

Terminals 1 and 3 are used; terminal 2 is not.

RCA panel jack

RCAJ RCA panel jack 2 Used as output jacks to connect to a flash unit or Opto-Switch Terminal 1 is connected to ground. Terminal 2 is connected to the desired output
Red LED RLED red LED 1 Used for power on indicator The shorter leg is negative. This is also the leg nearest the flat on the lip of the case.
LED holder LED-M LED holder 1 Used to mount LEDs on the project box.
