Hollyland DB25 toDual HDB15 TallyCable

Hollyland S-HOL-TCB10 DB25 Male to Dual HDB15 Male Tally Cable — Y-adapter tally cable converting a DB25 switcher tally output to two HDB15 tally inputs for the Hollyland Wireless Tally system.

The S-HOL-TCB10 is a Y-split adapter cable used when a broadcast vision switcher provides its tally output via a DB25 (25-pin D-Sub) connector and the Hollyland Wireless Tally controller requires HDB15 (15-pin high-density D-Sub) inputs. The dual HDB15 output allows the single DB25 tally bus to drive two separate Hollyland tally input ports simultaneously, enabling larger multi-camera configurations. This cable is typically used with high-end production switchers that consolidate multiple tally channels on a single DB25 bus.
