Why does the function of TALLY can not work? Hollyland Tech December 18, 2020 03:13 Updated Please confirm the model of the switcher, the TALLY interface definition is not the same on most switchers production, so it will cause that you can not use TALLY. Please confirm the ID of belt-pack, and check the TALLY interface from the base station to the switcher is correct Because the model of the switcher is different, make the TALLY button to the UP means low-level effective, push the TALLY button to the DOWN means high-level effective. Please check the "Tally Set" of the belt-pack is on, and the connection with the belt-pack TALLY interface is correct when you using the external TALLY light.
