5518-FM DIGITAL
TECHNICAL DATA
6-5
Power
Voltage:
85–264 VAC, 50–60 Hz, 30 VA.
Connector:
IEC, EMI-suppressed. Detachable 3-wire power cord supplied.
Fuse:
2.5A 20mm Quick Acting HBC, mounted on the power supply circuit board.
Grounding:
In order to meet EMI standards, circuit ground is hard-wired to chassis ground.
To avoid ground loops, we recommend using an FM exciter with a balanced composite
input.

10 lbs / 4.6 kg
Warranty
Two Years, Parts and Service:
Subject to the limitations set forth in Orban's Standard
Warranty Agreement.
Because engineering improvements are ongoing, specifications are subject to change with-
out notice.
Circuit Description
This section provides a detailed description of user-serviceable circuits used in the
5518. We do not provide detailed descriptions of the digital circuitry because most
of this is built with surface-mount components that cannot be removed or replaced
with typical tools available in the field. Field repair ordinarily consists of swapping
entire PC boards.
The section starts with an overview of the 5518 system, identifying circuit sections
and describing their purpose. Then each user-repairable section is treated in detail
by first giving an overview of the circuits followed by a component-by-component
description.
The drawing on page 6-27 shows circuit board locations.
Overview
The Control Circuits control the DSP, display, and input/output sections of the
5518 system.
