Features & SpecificationsFeaturesThis signal tracer /injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (suchas amplifiers, radios, tone controls, .) so as to detect the fault. In this way problems can be traced more easily. The signaltracer may also be used as a simple monitor or amplifier.Specifications : Output power: 0.5W / 8ohm Power supply: 7-9VAC or 9-12VDC / 150mA Dimensions: 60 x 53mm (2.4" x 2.1")Injector: 0-2.5Vrms output (adjustable) Output impedance: 1.5Kohm Frequency: 1kHzTracer: 3.5mV to 10Vrms sensitivity (adjustable) Gain: 40dB Input impedance: 50Kohm3
Assembly hints1. Assembly (Skipping this can lead to troubles ! )Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and willprotect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning. Thin raisin-core solder. Do not use any flux or grease. A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so theycannot fly towards the eyes. Needle nose pliers, for bending leads, or to hold components in place. Small blade and Phillips screwdrivers. A basic range is fine.0.000For some projects, a basic multi-meter is required, or might be handy1.2 Assembly Hints : Make sure the skill level matches your experience, to avoid disappointments.Follow the instructions carefully. Read and understand the entire step before you perform each operation.Perform the assembly in the correct order as stated in this manualPosition all parts on the PCB (Printed Circuit Board) as shown on the drawings.Values on the circuit diagram are subject to changes.Values in this assembly guide are correct*Use the check-boxes to mark your progress.Please read the included information on safety and customer service* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.4

Test & Usage12. TEST & USAGEConnect a test flex (preferably screened) to the in- and output (marked OUT, IN).Turn the potentiometers to their minimum position (completely to the left).Connect a loudspeaker (min 4 ohm 0,5W) to output LS and earth.2RV1RVFig. 1.0Connect either a transformer ( 2 X 7- 9VAC) to points VA and VB (fig 1.0), with its centre branching to earth,or a 9V battery with its plus pole to VA or VB and its minus pole to earth (fig 2.0).Disconnecting the power supply can be achieved using a switch (in the plus connection when using abattery, in the mains connection when using a transformer).To test the circuit, connect the output test flex to the input test flex.When you now turn both potentiometers, an audible test signal should come out of the loudspeaker, at leastwhen everything is working all right.8
TestingFig. 1.0Fig. 2.0Usage : Connect the earth of the signal generator/tracer to the earth of the circuit to be tested (to do so you mayuse one of the screens of the test flexes). Now you can "detect" or "inject" a signal at certain points of the circuit (e.g. the base of a transistor) so asto locate the defective component.9
