Trident 78 Introduction & Specifications
The Series 78 all analog consoles are all Trident through and through. The 78’s are Split/lnline consoles with
individual channels in 4-way panels. Using an 8 subgroup configuration and incorporating 6 Aux sends, its
routing options are vast and simple to use. Connections are fast and easy with DB-25’s throughout the board
and XLR’s for Master and Main outputs. With the 80B EQ at its core, including selectable channel inserts and
discrete preamps driving the inputs, the Series 78 consoles offer a wide array of summing and mixing options.
The uncompromised sonic quality and compact footprint of the 78’s are able to meet any demand.
