Denecke Dcode SB-4 Syncbox Timecode Generator
The Denecke Dcode SB-4 is a Syncbox timecode generator with a display and menu system for its timecode and settings, and it replaces the SB-3.
The SB-4 reads, generates, and jam syncs to all standard frame rates, 23.976 included, and cross jams whatever the incoming rate. It can also be set by hand and run as a stand-alone generator. Its temperature compensated crystal oscillator (TCXO) is ten times as stable as Denecke’s earlier generators, so one jam a day is enough. The SB-4 shows any drift between itself and a timecode input.
Timecode comes in on a 5-pin LEMO, which also carries timecode out and external power, and a BNC connector gives a second timecode output. The output level is selectable at 2.0, 1.0, 0.50, or 0.20 V, with no need for an external pad. Two AAA batteries run the SB-4 for 30 hours or more, or about 15 hours with the backlight on. The SB-4 also takes 6 to 18 V DC through the LEMO or 5 V through micro USB.
