After turning the amplifier off, let the unit sit for 3-
5 minutes before removing the input card or
access panel. This will allow the electrical charge
in the power supply capacitors to discharge.
Slave Phase Inversion (jumpers J12 & J13):
When the Upper two pins are shorted, this option inverts
the input signal, allowing a
Slave
amplifier to operate in the
Two in Series – Differential
configuration.
When the lower two pins are shorted, the input signal is not inverted, and the amplifier can operate as a
Master amplifier or as a Slave for any Series – Single Ended configuration.
Factory default:
Lower pins
shorted.
3.2.1
Configure for Use in a Series – Single Ended configuration
If you will be using a Series – Single Ended configuration for your system, complete the following:
For all except one SIM-BNC-OPTOC input cards for your system, remove the shunts from the
1.
Master/Slave jumpers (J6 and J7)
to configure the card to operate as a Slave. For the remaining card,
verify that the shunts are in place to configure the card to operate as a Master.
If desired, configure the Removable Barrier Block input connector option on the Master input card to
2.
allow the connector to be used as an unbalanced input.
3.2.2
Configure for Use in a Two in Series – Differential configuration
If you will be using the Two in Series - Differential configuration for your system, complete the following:
For one SIM-BNC-OPTOC input card for your system, remove the shunts from the
Master/Slave jumpers
1.
(J6 and J7)
to configure the card to operate as a Slave. For the remaining card, verify that the shunts are
in place to configure the card to operate as a Master.
On the SIM-BNC-OPTOC input card that is now configured for Slave operation, move the shunts
2.
positioned on the lower two pins of
jumpers J12 and J13
and place them on the UPPER two pins of
jumpers J12 and J13. This will allow the input signal received by the Slave amplifier to be inverted.
If desired, configure the Removable Barrier Block input connector option on the Master input card to
3.
allow the connector to be used as an unbalanced input.
3.3
Install SIM-BNC-OPTOC Input Cards in Amplifiers
Before preparing the amplifiers,
make sure the amplifier is
turned off for at least 3-5 minutes and the AC mains are
disconnected.
Locate the standard SIM-BNC Input Card on the right side of the rear panel of each amplifier.
1.
Use a #2 Phillips screwdriver to remove and retain the two (2) screws located at the edges of the input
2.
card.
Unplug the ribbon cable from the back of the input card; remove the card from the amplifier card bay.
3.
For each amplifier, plug the ribbon cable into the ribbon connector on the SIM-BNC-OPTOC card. Reinstall
4.
the card into the card bay on the amplifier back panel and secure in place using the retained screws.
(optional) We recommend labeling each SIM-BNC-OPTOC card as “Master” or “Slave” to identify the
5.
configuration of the installed input card.
3.4
Configure Amplifiers’ Main Boards for Slave Operation
2100/7000-Series amplifiers are configured by default for use as
stand-alone (or Master) amplifiers. When creating a Series multiple
amplifier system, you must also configure each amplifier’s
main board
for Slave operation on the amplifiers to be used as a Slave(s) in the
system. Note that the main boards installed in the 2100 and 7000
Series models are identical, but the method for accessing the main
board varies between models.
Do not attempt to access the Main Board
while the amplifier is running. Turn the
amplifier off and disconnect the AC Mains
before removing the input card or amplifier
access panel.
