OCX-V GEARBOXING MODE
In Gearboxing Mode, the OCX-V always generates an output clock at the sample rate
set by the SAMPLE RATE knob, regardless of the incoming reference frequency. This
output clock is still phase-locked to the reference input, but the sample rates need not
match.
For example, you may set the SAMPLE RATE knob at 48 kHz and apply a 44.1 kHz
reference. The device then “gearboxes” 44.1 kHz into 48 kHz output, as selected by
the SAMPLE RATE knob. This ability to lock to one sample rate and generate another
is very useful for sample rate conversions.
For Gearboxing to work, the incoming reference must be one of 63 recognized valid
frequencies. A valid frequency is
1) one of the standart frequencies: 32, 44.1, 48, 88.2, 96, 176.4, 196 kHz;
2) a standart frequency subjected to every possible combination of US and Euro pull
up/downs (9 combinations are possible).
See Appendix A for a complete table of all valid frequencies.
