Introduction
In choosing the 504 Stereo FM Tuner you have acquired a component that
combines major advances in audio and user interface design. The 504
Stereo FM Tuner uses dual-gate MOSFET RF amplifiers for high sensitivity,
together with a Walsh function stereo decoder for low distortion and extra
HF bandwidth. The eight-character display can be programmed to show
station names for ease of access, and all functions can be remotely
controlled from the Meridian System Remote.
This guide is designed to enable you to obtain the best possible results
from the unit, whether your requirements are simply to listen to music, or
to configure the unit to your preferences.
If you have just purchased the 504 Stereo FM Tuner, you should first turn
to the section Setting up the FM tuner, page 17, which explains how to
unpack and install the FM tuner correctly.

Introduction
The Meridian 500 Series
The Meridian 500 Series is a unique system of digital, analogue,
and video components designed to meet the demand for
absolute quality, ease of use, and lasting value.
The flexibility of the Meridian 500 Series is such that you can
assemble a system as simple or as complex as you need,
perfectly suited to your musical and environmental requirements,
and with the ability to add to it or change it at a later date should
your requirements change. The 500 Series is also compatible
with the existing Meridian 200 Series and 600 Series
components.
Each Meridian 500 Series component is housed in a matching
slim line case. Front panel controls provide access to the most
important functions, and the full range of functions is available
from the Meridian System Remote using a simple and intuitive
control interface.
500 Series communications
The Meridian 500 Series includes a sophisticated
communications link, to ensure that any configuration of units
will work together as a fully integrated system.
The 500 Series communications system allows you to control
any combination of units using a single remote, and ensures that
your commands from the remote are interpreted unambiguously.
The communications system also allows you to extend your hi-fi
system into two or three rooms, with the ability to control the
sources in one room from the controller in another room.
Professional features
The 500 Series also includes features for professional users,
including RS232 computer control and balanced connections.
The following pages give examples of four suggested
configurations to illustrate the flexibility of the Meridian 500
Series.
