8. AC Power sequence connector
A three-pin Euro style terminal and mating connector are supplied with each amplifier to
allow the amplifier to be sequenced on or off remotely. This allows multiple amplifiers to be
powered on or off locally by using the first amplifier as the on/off master. These terminals
are located on the rear panel of the amplifier and are labeled SEQUENCE. The three termi-
nals are from left to right and labeled ground, SND, and RCV (see Figure 6).
The sequence feature can be used to turn on or off one or more Bose
used with more than one amplifier the sequence feature will turn the amplifiers on or off
sequentially at about 0.5 second intervals. This will prevent a large turn-on surge through
the AC mains supply that could possibly cause disruption of the flow of current through the
AC mains.
SEQUENCE
SND RCV
Turning a single amplifier on or off:
Connect the positive side of a 12 to 15 VDC supply to the RCV terminal of the SEQUENCE
connector. Connect the ground side of the 12 to 15 VDC supply to the GROUND terminal of
the sequence connector.
The amplifier will remain on as long as the DC voltage is present. The amplifier will turn off
when the DC voltage is interrupted by opening the circuit at the SEQUENCE connectors. If
a switch is used to control the SEQUENCE circuit, it should be a SPST (single pole single
throw) type. A control device such as a contact closure contained within a system such as

, AMX

or Panja
The contact closure must be a latching type and not a momentary contact closure.
Turning multiple amplifiers on or off:
Starting with the first amplifier in the sequence to be turned on, connect the positive 12 to
15 VDC to the RCV terminal. Next, connect a wire from the SND terminal of the first ampli-
fier to the RCV terminal of the next amplifier to be turned on. Continue in this manner until
all amplifiers in the sequence are connected.
If the amplifiers are mounted together in a rack where the chassis grounds are connected
through common connection via the metal rack rail or by a common AC ground, no other
connections should be required (see Figure 7). If this is not the case, simply connect all of
the chassis ground terminals together (see Figure 8).
