Using Effects
This section explains how to connect external effects processors and apply effects to MT400
signals during recording or mixdown. You may use either the INSERT I/O jacks or the AUX
SEND jacks to apply effects to input channel signals and tape tracks.
Using INSERT I/O
Input Channels 1 and 2 of the MT400 feature INSERT I/O jacks to connect external effects
processors. These make it easy to apply effects to certain channels and tracks during track
recording and mixdown. Typically, you can use compressors, limiters, noise gates, equalizers,
and other effect units that process dynamics and the tonal color of sound.
The INSERT I/O connections, which use TRS (Tip, Ring, Sleeve) phone jacks are two-way
connections, with the tip carrying the input channel signals from the MT400 to the external
processor and the ring carrying the processed signal from the external processor back to the
input channels of the MT400.
Signal path through the TRS phone jack
You will need a special insert cable as shown above to connect external effects processors to
the INSERT I/O jacks. Optional insert cables YIC025/050/070 are available from Yamaha.
Refer to the following diagram of the effects processor connection.
