3.1
Choosing Single-Ended or Differential Configuration for Two-amplifier Systems
Series amplifier systems can be configured with the load
ground-reference (single-ended output) or floating
(differential output). Refer to
Figure 3.1
and use the
following guidelines to select a Single-Ended or a
Differential configuration.
For Series configurations requiring only two
1.
amplifiers, the
Two in Series - Differential
configuration is safer and is easier to build than
Single-Ended output.
Series configurations requiring more than two
2.
amplifiers should be wired using a
Single-Ended
configuration.
Regardless of the number of amplifiers in the system,

if the load will ever be ground referenced, a
Single-
Ended
configuration
must
be used.
3.2
Configure SIM-BNC-OPTOC Input Cards
Each amplifier in a Series multi-amp system uses a
specialized input card that functions to synchronize the
operation of all amps in the system and provides for
optical isolation. The input card allows you to designate
(via jumpers located on the card), that the input card will
function as a Master (sending synchronization
information), or will function as a Slave (receiving synchronization information). Other options for system
configuration and operation can also be selected via jumpers located on the input card. Refer to
Figure 3.2
for the jumper locations.
Master/Slave (jumper J6 & J7):
When J6 and J7 are Open, the
input card will be operating in an
amplifier that will act as a Slave in
a multi-amplifier system. When
Shorted, the input card will be
operating in an amplifier that will
act as a Single amplifier, or as a
Master amplifier in a multi-
amplifier system.
Factory default:
Shorted for individual amplifiers
and Master amplifiers sold as a
part of a multi-amplifier system.
Removable Barrier Block Input Connector, Balanced/Unbalanced (jumper J4):
When Open, this option
lifts the ground for the Removable Barrier Block connector, allowing it to be used as an unbalanced
input. When Shorted, the ground leg is enabled on the Removable Barrier Block connector.
Factory
default:
Open.
