The PTASG1 is a portable or benchtop audio oscillator used in applications requiring a stable audio signal source for system verification, alignment and testing. The internal oscillator operates at 700 Hz allowing aural monitoring of the signal without the fatigue associated with oscillators running at a higher frequency such as 1000 Hz. The 700 Hz signal falls in the passband of an audio system and is easily distinguished from either 400 Hz or 1 kHz signals. The oscillator output is compared against an internal temperaturestable reference in a gain controlled loop that adjusts the final output level with stability suted to accurate bench top audio testing. Two outputs are provided on the PTASG1. The XLR balanced output is frontpanel switch selectable for MIC or LINE level. The line level is factory set to 4 dBu, but can be programmed to 6 dBu. When the frontpanel level switch is set to MIC, the XLR output level is set to 46 dBu, 50 dB below 4. The unique output network produces the same output level into low impedance 200 and higher impedance 1 k mic preamps. The PTASG1 operates either from an internal 9 volt battery or from an external 12 Vdc to 30 Vdc supply. Test leads and a bench top support bracket are included. A switch in the battery compartment allows the user to preset the balanced linelevel output to 4 dBu or 6 dBu.
