Power Up via Boulder Link

With each component connected together with a Boulder Link

cable and individually connected to the AC mains, pressing the

1021’s front panel Standby button will begin the turn-on sequence of

all components. When a “MASTER” 1021 is powered up, it will search

for any “SLAVE” units connected to it. As the master nds each slave,

the slave’s ID number will be shown on the display.

If any of the connected slaves are ampliers, each time the master

is brought out of Standby mode it will display “WAITING FOR AMPS.”

Each amplier will be turned on in the order of their Boulder Link ID

number. To minimize turn on time, the ampliers’ Boulder Link IDs

should be set to the lowest sequential numbers possible other than

0. For example, use 1, 2, and 3 instead of 13, 14, and 15. An amplier

set to ID 15 will take 47 seconds to turn on.

A 1021 set to “SLAVE” will display “THIS UNIT SLAVE #23”. If there is

no component set to “MASTER,” the 1021 will display “THERE IS NO

MASTER!” In this case, the 1021’s rear panel MASTER/SLAVE switch

should be set to MASTER. It may take up to 30 seconds for the 1021

to recognize the switch change.

Boulder Link Messages

Each component in the system can send a message to the 1021,

which is then shown in the Progress Bar portion of the display. This is

particularly helpful in conrming the operating status of each power

amplier in a multiple amplier system.

“AMPLIFIER 1 ERROR” means that an internal power supply

has failed and Amplier 1 has turned itself off to protect the

speakers from damage.

“AMPLIFIER 1 HAS DC” means that Amplier 1 has turned itself

off due to a DC offset voltage being detected at its inputs.

“AMPLIFIER 1 IS HOT” means that Amplier 1 has turned itself

off due to a higher than normal temperature condition on the

heatsinks.
