Description
TOA TS-919B4 4-Wire Station Bridge Unit for TS-910
Product Details
The TOA TS-919B4 is “a Bridge unit for connecting four Wired Conference units of the TS-811, TS-911, TS-812, or TS-912”, cabled to each conference unit with Category 5.
It is the four-seat version of the TS-919B1, and it is the part to specify wherever wired units cluster — a row of delegate desks, a table of four. One box, four RJ45 conference unit connectors, four connection status LEDs, and one run back to the TS-918 expansion unit instead of four.
The trade-off is loss: branching four ways costs 17.5 dB upstream against the single unit's 16.5 dB, and insertion loss is 3 dB upstream against 1 dB. Those figures are in the table below and are worth checking against a long cable plan. It draws 26 mA at 24 V DC from the expansion unit.
