THIS AUCTION is for the Timetrax 70 amplifier PLUS the Model 20 Sensor Pickup included ! Once again, this auction comes with the SENSOR. This auction does not come with a smartphone, It does not come with a clock. It does not come with any software. It does NOT come with an oscilloscope. Included in this auction is ONE (1 piece) of Timetrax Model 70 beat amplifier, 1 pc. Timetrax Model 20 clip on sensor, 1 pc interface cable to connect to your PC or Smartphone external microphone input jack, 1 set of headphones, 1 pc USB C adapter cable.
The Timetrax Model 70 unit is a high impedance, high gain sensor amplifier capable of detecting ticking sounds from a mechanical escapement. It is specifically designed to work with our legendary Timetrax Model 20 clip on Sensor for clocks which is included with the unit. It is also compatible with the Timetrax Model 100 watch sensor w/vise (optional, not included). The robust construction includes a proprietary custom injection molded ABS case with an extruded anodized aluminum outer shell. The underside of the housing has the battery compartment with a removable battery door providing the user with access to replace/install 3XAA Alkaline batteries (not included) that power the unit. An electronic, digitally controlled gain control allows the amplitude of the sound level from the speaker to be adjusted. Another new feature in this unit are the pair of signal output jacks and interface cables. One set is a specially designed cable output that plugs directly into your smartphone or PC external microphone input jack. This provides you with a means to use public domain timing machine software/Apps together with a precision, highly sensitive pickup. In addition, you can plug the set of earphones INCLUDED. This provides you with the option to listen to and adjust the beat of the timepiece through the privacy of your headphones as the speaker output is disconnected once the cable or earphone plug is installed.
