Sequential Turn-On

Sequential Turn-On Operation

Black Max amplifiers contain a sequential turn-on1feature that is designed to turn on a bank of Black Max amplifiers, one at a time, in sequence with approximately second between each amplifier. This type of sequencing of power is necessary in large systems where the in-rush current of all the system amplifiers turning on at once would over- load the AC mains supplying the system.

The first amplifier in the chain will act as the master amplifier controlling the power-up for the group. When it is switched on, it will initiate the power up sequence.

To prepare/wire multiple Black Max amplifiers for sequential turn-on operation, do the following:

Preparation & Wiring

Turn off all amplifiers and unplug from AC.

The amps should be wired together in a daisy chain fashion. Wire the XMT connections of one amp to the RCV con- nections of the next amp as shown in the diagram.This pat- tern is continued until all the desired amplifiers are connect- ed. The last amplifier in the chain has no connections on its XMT terminals, and the first amplifier has no connection to its RCV terminals.

Note: The RCV and XMT terminals have both polarity and number indicators. In daisy chaining the amplifiers, the same connection pattern is used: Pin 4 ("+") XMT of the previous amp to Pin 2 ("+") RCV of the1 next amp and Pin 3 ("-") XMT of the previous amp to Pin ("-") RCV of the next amp.

Switch Settings

The position of the Power Sequencing Switch of the Black Max is important in sequencing setup.The master amplifier’s Power Sequencing Switch MUST be set to OFF. By setting the switch to OFF, this amplifier will turn on and off directly by its front Power Switch. All other amplifiers in the chain MUST have their Power Sequencing switches in the ON position so that they respond to the sequencing signals. All slave amplifiers MUST have their front Power Switch set to the ON position, with the exception of the master amplifier.

To Begin the Power Up Sequence

Turn on the first amplifier1 in the chain. All others will follow in sequence with a second delay between them.

Power Down of Sequenced Amplifiers

When the first amplifier in the chain of sequenced amplifiers is switched off, all other amplifiers will also switch off imme- diately.

Troubleshooting Sequencing Problems

If an amplifier in the chain does not have its front Power Switch set to ON, it will not power up. However, all other amps that follow that amplifier will continue to sequence. If an amplifier in the chain does not have its Power Sequencing Switch in the ON position, it will break the daisy chain. It will, in effect, become a second master ampli- fier controlling all amps that follow it. In this case, if the Power Switch for this amp is switched off, the sequencing will stop at that amplifier. If this amplifier’s Power Sequencing Switch is set to ON, then all amplifiers following it will have already begun to sequence.

Should an amplifier in the sequence shut off either by tripping its circuit breaker or by someone turning the Power Switch OFF, only that amplifier will lose power. All units that follow will remain powered up. If however,AC power is removed from an amplifier by unplugging the power cord, all other amps following it will immediately power down. An amplifier in the chain going into or coming out of low power sleep mode will have no effect on the group.
