RDL ST-OSC2A Test Tone Generator

The ST-OSC2A is a miniature wall and surface mount dual audio oscillator from RDL. The module provides separate left and right audio signals for each of two frequencies - 1kHz and 10kHz, and is well suited to audio installations requiring reference tones for level calibration and frequency response checks

Dual, amplitude-stable oscillators provide precision sine-wave audio signals at 1kHz and 10kHz

Multi-turn level adjustment permits precise output setting

Separate output level control provided for each oscillator

Low-impedance outputs drive virtually any audio line

Outputs may be connected to either balanced or unbalanced lines

Integral AGC circuitry provides stable output level
