Yamaha MT120 - Manual (Page 23)

USING THE GRAPHIC EQUALIZER
The MT120 has a stereo 5-band graphic equalizer built in. As the block diagram below makes clear, signals assigned to the
left and right channels by the PAN control and level adjusted using the MASTER fader are sent to the equalizer. Therefore,
it can be used during ping-pong recording, mixdown operation and when recording with the REC SELECT control set to “L”
or ‘R.” The equalizer cannot be used when the REC SELECT control is set to “1” — “4,” however, since each channel signal
is recorded directly on the appropriate track.
The graphic equalizer affects only the signal paths marked with bold lines in the diagram below.
