ST-OSC2A

RDL ST-OSC2A - audio oscillator with 1 kHz and 10 kHz sine waves

RDL ST-OSC2A is a precision dual audio oscillator designed for testing, calibration and diagnostics in professional AV systems. It generates two stable sine-wave tones at 1 kHz and 10 kHz, ideal for verifying signal paths and measuring system response.

Each oscillator provides two separate outputs, allowing stereo line testing or dual-path signal injection. Outputs are compatible with balanced and unbalanced lines, and multiturn level controls enable precise output adjustment. Built-in AGC circuitry ensures amplitude stability under varying power conditions.

The module features RDL’s SupplyFlex power input configuration, supporting floating 24V DC or bipolar DC sources. A jumper allows grounding the power supply relative to module ground.

Functionality:

• dual sine-wave oscillators: 1 kHz and 10 kHz
• amplitude-stable output - precision signal source
• two outputs per oscillator - stereo or dual-path testing
• balanced and unbalanced line compatibility
• multiturn level adjustment for each oscillator
• built-in AGC - automatic gain control for stable output
• SupplyFlex power input - 24V DC or bipolar DC
• optional ground-referenced power configuration

Features:

• ideal for system calibration, frequency response testing and diagnostics
• compact design - easy integration into AV racks or panels
• reliable reference tones for professional audio environments
• compatible with RDL systems and other AV equipment

RDL ST-OSC2A is a trusted tool for AV professionals, offering stable, precise audio tones and flexible integration for a wide range of testing applications.
