TB125 is the fold back mixer which inherited a concept of FBMX3.
It provides by 4 reference variable input and 2 reference variable output.
It meets not only the line but also the microphone level and can use the input for various applications such as microphone / line mixer, talk back system, the line monitor.

“Input”
Input 1 or 2 and 3 can change a reference level of -20 or +4dBu, and, as for input 4, a change of -60 or +4dBu is possible.

“Routing”
4 input signals are sent to the mix amplifier via each mix level and ON button.

“Output”
The mix signal is output via a reference changeover switch of +4/ 20.

“Signal meter”
The signal can monitor each input and output of the mix amplifier in 5 points of bar graph of the VU response.
The meter scale is -10, -5, 0, +3, +6dB.

“Monitoring”
It switches 4 input and 2 output and can monitor it with headphone.

“Others”
Please refer about the manufacturing of the connection cable to specifications.
