An electronic, digitally controlled gain control allowsthe amplitude of the sound level from the speaker to be adjusted.Another new feature in this unit are the pair of signal output jacks andinterface cables. One set is a specially designed cable output that plugsdirectly into your smartphone or PC external microphone input jack. Thisprovides you with a means to use public domain timing machine software/Appstogether with a precision, highly sensitive pickup.

a). Plug in the sensor cable into the center input jack of the unit and Sensor end with the Alligator Clip on the movement under test. Completely unwrap the sensor cable and extend it to its full length. Locate the unit as far away from the ticking sound of the movement under test to minimize coupling and response. This is very important as you do not want sound from the speaker being picked up by the sensor and creating a positive response.
b). Adjust the volume control with your finger tip by sliding the toggle left or right. Louder is to the right, Softer to the left. You can slide and hold the toggle to automatically increase or decrease the volume. Or you can slide it one step at a time to achieve the desired sound 2: Basic Beat Amplifer with External Earphones (Optional, Not Included)
a). Follow all of the steps outlined in Mode 1 above. Plug in your earphones to the output jack on the left. This will connect sound to the earphones and will disconnect the speaker
b). Note: when using headphones you do not need to worry about maximizing the separation distance between the movement and the speaker.
Mode 3: Beat Amplifier Connected to Smart Phone or PC external microphone input
a). Follow all of the steps outlined in Mode 1 above. Plug in the interface cable supplied with the unit. Be careful which end you plug into the Timetrax and the Phone/PC. NOTE: when you plug the cable into the LEFT output the speaker is disconnected similar to Mode 2. The Smart Phone/PC end is the stereo plug with the multiple rings, while the Timetrax end is the single ring plug. Plug the single ring plug into the OUTPUT Jack of the amplifier on the LEFT side. Plug the multiple ring plug into your PC/Smart Adjust the input level control on your PC/Smart Phone to achieve desired signal strength. If the signal is too strong, reduce the setting of the volume control on the Amplifier. An even lower signal strength can be achieved by switching to the output jack on the RIGHT side of the Amplifier, While the RIGHT output is the low level millivolt signal used to interface to Instrumentation such as an Oscilloscope it can be used with some phones/PC’s as well.
Only use the interface cable supplied with this unit to connect to your phone/PC. DO NOT USE any other cable from any other manufacturer.
c). Sound/Voice Recorder:
Virtually every Smart Phone, PC has an App/Program that allows you to record sound. It might be called the “Sound Recorder” or “Voice Recorder.” You can use that piece of software to test the input levels in your system. This is a good “first step” prior to using the device with a Timing Machine App or PC Software. Once you have verified the connection, sound levels including play back, you are ready to use the Timetrax Model 60 with your Timing Machine Software of your choice.
