rolls Generators Editorial Review
The Rolls MO2020 Testoscillator Sine/Square Wave Generator garners a mixed reception among users, showcasing both commendable features and notable drawbacks. Many customers appreciate its solid build quality and the linear switch movement, which allows for finer adjustments to the output signal. They particularly value its reliability in testing sound systems, providing stable sine and square wave outputs across a frequency range that typically meets their needs. Users have noted that while the output amplitude remains Consistent, fine-tuning can be challenging due to the knobs' wide range with limited movement, making precise adjustments difficult. Complaints about total harmonic distortion (THD) levels, exceeding the advertised specifications, have also surfaced. This issue is critical for users relying on the oscillator to provide clean signals for testing other amplifiers. Moreover, adjustments to the PCB's frequency range require internal access, which can be cumbersome, and many users lament the lack of clear documentation regarding its voltage controlled oscillator (VCO) functionalities, indicating a disconnect between the product's capabilities and user expectations. Despite these shortcomings, the overall sentiment remains positive, especially concerning customer service and the product's effectiveness in its primary functions. In conclusion, while the Rolls MO2020 Testoscillator is praised for its durable Construction and operational efficacy, potential buyers should be aware of its limitations in fine-tuning and THD performance, which may vary from unit to unit. **
