SE-70: Setting Input Level
The input level of the Boss SE-70 should be adjusted to match the level of the
connected instrument. Use the following procedure to adjust the input level:
1) Plug your instrument into the INPUT jacks on the back of the SE-50. Use the
left input for a mono signal, use both inputs for a stereo signal.
2) While playing your instrument, adjust the appropriate INPUT knobs on the
front panel until the OVERLOAD LED(s) light during the highest signal level
NOTE: The OVERLOAD LEDs will light at 6dB below clipping.
