Anyway, these are the Boss ES-8 specs for loops’ input and output, maybe it’s useful to match the correct settings in the TimeFactor:
Nominal Input Level
IN 1–2, RTN 1–6, RTN 7L, RTN 7R, RTN 8L, RTN 8R, RTN VOL: -10 dBu
Maximum Input Level
IN 1–2, RTN 1–6, RTN 7L, RTN 7R, RTN 8L, RTN 8R, RTN VOL: +18 dBu
Input Impedance
IN 1, 2: 1 M ohms (Buffer: On)
Nominal Output Level
SEND 1–7, SEND 8L, SEND 8R, SEND VOL, OUT 1/L, OUT 2/R, TUNER: -10 dBu
Maximum Output Level
SEND 1–7, SEND 8L, SEND 8R, SEND VOL, OUT 1/L, OUT 2/R, TUNER: +18 dBu
Output Impedance
OUT 1/L, OUT 2/R: 1 k ohms (Buffer: On)
TUNER: 1 k ohms
Recommended Load Impedance
10 k ohms or greater
