Installing the Optional DB-25 Balanced Connector:
The female
DB-25
balanced
output option may be installed by qualified service personel without need for additional
parts as follows:
1)
Remove power from the unit.
2)
Remove the top cover from the chassis of the
AMP-S8
unit (set the screws aside for later
reassembly).
3)
The standard unbalanced
HD-15
connector is attached to the rear panel by a plate. Under this connector and
plate is the cutout for the optional
DB-25
connector. Inside the unit, the
HD-15
connector (
Item N
) is
connected to an output PCB module (
919224
). Unplug the female
DB-25
connector (
Item O
) from the other
end of this module. Note that the
DB-25
connector terminates an internal ribbon cable.
4)
Remove and set aside the two screws, nuts, and washers from the
HD-15
connector plate attached to the rear
panel and remove the connector/plate/module assembly from the unit.
5)
Use the two screws, nuts, and washers removed from the disassembled
HD-15
connector plate to install the
DB-25
connector into the larger connector cutout now revealed.
6)
Reassemble the top cover to the chassis.
NOTES:
•
The
DB-25
balanced
option may be specified at time of order and the conversion performed at the factory.
•
Once conversion to a balanced
DB-25
connector is done (following steps
1
-
6
above), a special dongle is
available which may be plugged into the
DB-25
connector to easily convert it (back) to an
unbalanced
HD-15
connector. Contact
Wohler Technologies
for more information on this dongle.
RS232A Input/Output Connector
This DB-9 connector is used for downloading programming, setup, and diagnostic information into and out of the unit.
Remote Connector
(Option for 2U Models only)
This option is available only on the 2U rack
AMP2-S8
models. This connector is not installed in standard 2U models
and is available for installation with a retrofit kit, or as an option when ordering. When installed, it allows remote control
over input source selection or other other aspects of the system as may be specified in a special order. Contact
Wohler sales for special order inquiries (email: [email protected]).
