S4 Input Bus – This switch allows the input signal bus to function across all six relay circuits for six
single-channel amplifiers, or be split for three dual-channel amplifiers. Thus, if switches S2 and S3 are
set to either
1CH or 2CH , this switch must also be set to the same operating mode. See the note below.
S5 Output Bus – This switch allows the output signal bus to function across all six relay circuits for six
single-channel amplifiers, or be split for three dual-channel amplifiers. Thus, if switches S2, S3 and S4
are set to either
1CH or 2CH , this switch must also be set to the same operating mode. See the note
below.
NOTE
Switches S2, S3, S4 and S5 must be set to the same operating position. Do NOT operate any of the
