A specific calibration track is necessary for a successful calibration of any of the OEM integration DSP products. Select the product you need to calibrate from the list below to download the correct calibration track:
For setting the input sensitivity on an amplifier using our 9-step method, a sine wave test tone recorded at 0 dB reference level in the frequency range to be amplified is needed. Select the tone appropriate for your application from the list below to download the track:
When setting up and tuning the TwK™ processors or VXi amplifiers we recommend using a pink noise test track, which is a random noise filtered to have equal strength per octave across the standard listening spectrum (20 hz - 20 kHz). Pink noise is widely used for testing the frequency response of an audio system, and is especially useful when paired with an Real Time Analyzer or Fast Fourier Transform analyzer. A mono pink noise track is also provided below, which is useful for determining the behavior of a center channel in an up-mixed factory set up. It is also useful for testing whether an all-pass filter is being used in a stereo setup. As with stereo pink noise, it is also used for testing frequency response of individual channels. You can download both 15 minute pink noise tracks at the links below:
You can also purchase a Calibration CD containing these tones along with additional test tones and helpful system tuning tracks.
