To remotely begin the sequencing function, close the circuit and supply the DC voltage to
the RCV receive pin on the first amplifier. The subsequent amplifiers should turn on at 0.5
second intervals.
Note: The front panel power switch should be in the STANDBY position on all of the
amplifiers in this group.
When the DC voltage is interrupted, the amplifiers will then turn off. If there are signal
processing and input source devices in the system, they should be turned on before the
amplifiers are sequenced on, and these same devices should be powered down after the
amplifiers are sequenced off. This will avoid large transient thumps being passed to the
loudspeakers attached to the system.
When using multiple amplifiers that utilize the SEQUENCE feature of the Bose
you would like to power them on, but remote operation is not required, you do not need the
DC Voltage to activate the SEQUENCE function. Simply connect the SND send terminal of
the first amplifier to the RCV receive terminal of the next amplifier and so on (see Figure 9).
The front panel power switch of the first amplifier will activate the SEQUENCE function
when switched to the ON position. All other front panel power switches should be in the
STANDBY position for the SEQUENCE function to operate properly. Again, if the amplifiers
are mounted together in a rack where the chassis grounds are connected together through
common connection via the metal rack rail or by a common AC ground, no other connec-
tions should be required. If this is not the case, simply connect all of the chassis ground
terminals together.
