The T-6240 is a public address pre-amplifier with eight line level inputs, one unbalanced MIC input and two EMC(priority) level inputs. Each of the eight input channels can be selected via front panel push buttons for use with the MIC input, in this way the T-6240 can be used to page individual channel. Priority muting is achieved via EMC1-2 inputs for overriding other inputs except Mic1. Individual gain controls are provided for each channel and MIC inputs.
