The clock oscillator was designed to accept a signal at the desired sample rate, or work directly from a low-cost watch crystal, setting the sample rate at 32.768 KHz. Although the FV-1 is not restricted to this sample rate, a 32.768 KHz clocking frequency does allow a signal bandwidth of 15KHz, which is entirely adequate for most audio effects applications, and allows full use of the FV-1 internal memory, allowing a full second of audio delay time. The internal clock of the FV-1 is all the while running at 1024 times the crystal frequency, and when running at 32.768KHz, the circuitry of the FV-1 is running internally at 33.55 MHz, but then, you don't need to know that to use the FV-1.
