The SB-3 Syncbox Time-Code Generator from Denecke reads, generates, and jams to all standard frame rates including 23.976 and all common SMPTE rates. It features outputs for time code and word clock. Word clock is generated in 44.1, 48, 96, and 192KHz and other standard time-code rates. TCXO (temperature compensated crystal oscillator) ensures low drift and very low word-clock jitter. The unit allows you to cross-jam regardless of incoming frame rates. The unit continuously jams to new code so there is no need to power down the unit to re-jam. It runs on (2) AA batteries and includes a battery-warning indicator to gauge its remaining power level.
