RDL PT-ASG1 – Portable 700 Hz Audio Signal Generator

What is the RDL PT-ASG1?The RDL PT-ASG1 is a portable or benchtop audio oscillator that provides a stable 700 Hz signal for system verification, alignment and testing. Its balanced XLR output switches between mic and line level, with the line reference preset to +4 dBu or +6 dBu. It runs from an internal 9 V battery or an external 12 to 30 Vdc supply, and test leads and a bench support bracket are included.How does it work?The PT-ASG1 oscillator runs at 700 Hz, which is easy to listen to for long periods and easy to distinguish from 400 Hz or 1 kHz signals. The output is compared against an internal temperature-stable reference in a gain-controlled loop, giving output stability better than 0.01 dB. The balanced XLR output is switch-selectable on the front panel for MIC or LINE level. Line level is factory set to +4 dBu and can be changed to +6 dBu with a switch in the battery compartment. In MIC mode the output is -46 dBu, 50 dB below +4 dBu, and holds the same level into 200 Ω or higher-impedance preamps. A phono output provides a -10 dBV consumer-level signal. Power comes from an internal 9 V battery or an external 12 Vdc to 30 Vdc supply at 20 mA. Replacement test leads are offered by RDL as the PT-TLS1 (female XLR and clip leads) and PT-TLS2 (male XLR and clip leads).What are the key features? Stable 700 Hz tone — Comfortable for aural monitoring and easy to identify in a system. Mic or line output — Front-panel switch selects -46 dBu mic or +4/+6 dBu line on XLR. Precision reference — Output stability better than 0.01 dB. Balanced and unbalanced outputs — XLR balanced plus a -10 dBV phono output. Battery or external power — Internal 9 V battery or 12 to 30 Vdc. Accessories included — Test leads and a bench top support bracket. Where is it typically used?
