A calibrated reference signal generator, producing a 1Khz sine wave with low distortion and noise. Alternatively, it can output a white noise signal, useful for measuring frequency response of systems such as equalisers and filters, as well as being used in the process of making speaker IRs.
(Due to strict regulations regarding batteries in mail deliveries, we are unable to include a 9V battery with this product)
Features:
- +4dBu, 1V peak and -10dBv output settings.
- Calibrated to <1% peak-to-peak error.
- Outputs:
- 1Khz sine wave
- White noise
- Pink Noise
- Powered by a 9V battery.
- Open source firmware means unit can be re-programmed and hacked with custom firmware.
- Includes conversion table on the back panel.
Use cases:
- Calibrating exact input gain level on audio interfaces.
- Measure exact analog-to-digital converter levels for accurate behaviour of analog-modelled software plugins.
- Calibrating bias on reel-to-reel tape machines.
- Pink noise microphone levelling.
- White noise capture method for creating speaker Impulse Responses (IRs).
