Introduction

The Meridian 519 Laser Demodulator is part of the 500 Series of advanced high-fidelity equipment.

In purchasing a Meridian 519 Laser Demodulator, you have acquired a refined piece of equipment that will continue to bring you listening pleasure for many years. This manual will enable you to get the most from it.

About the 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 requirements, and with the ability to add to it or change it at a later date should those requirements change.

The Meridian 500 Series includes a sophisticated communications link, to ensure that any configuration of units will work together as a fully integrated system.

Unpacking the 519

On opening the carton, you should have found the following parts:

• Meridian 519 Laser Demodulator
- Power cord
• Meridian Comms lead
- This manual

If any of these items is missing, please contact your dealer. We suggest that you retain the packing carefully as it provides maximum protection for the unit in transit.

Installing your 519

General precautions

Before carrying out any installation, you should ensure that the 519 is marked with the correct voltage for your local AC supply. Should this not be the case, do not proceed – but contact your dealer.

As a general rule, you should not make any connections to the 519, or to any other component in your system, whilst the AC power supply is connected and switched on.

Siting

We recommend the following guidelines for location.

• The 519 should not be placed on top of a power amplifier.
- Avoid sites where it would be subjected to direct sunlight or where it is near a heat source, e.g. a central heating radiator
- Avoid sites where the 519 could be subjected to strong magnetic radiation, like near a power amplifier.
- Not too close to a television, or where connecting cables may be subject to, or cause, interference.

Connections

There are five types of connection that may be made to the 519:

• power
• Laser Disc RF
  • electrical digital audio
  • optical digital audio
• communications.

Digital audio and RF connections need to be made to other components in your system. Communication connections have to be made to most of the other Meridian components in your system in order for them to act as one system. The connections to your 519 are very important and care should be taken in deciding which connections to make.

A typical installation would be:

graph LR
    A["Laser Disc Player"] -->|75Ω| B["Meridian 519"]
    A -->|Optical| B
    B -->|Optical In Comms| C["Meridian 562 or 565 Comms"]
    B -->|Optical| C
    D["RF Out"] --> A
    E["Optical Out"] --> A

Note Electrical digital audio connections may be used in place of the optical connections.

Tip In common with all digital products, the 519 emits some radio-frequency signals. For this reason, try to keep all power cables and Comms leads away from audio, antenna and loudspeaker cables. Some time spent laying out the cables carefully will repay you with the best possible performance later.

Starting off with 519

Checking

Before turning on the power, check once again that you have made all the connections correctly.

The 519 is designed to be left connected to AC power at all times and can be run continuously.

Switching on

The power switch is located directly next to the power inlet on the rear of the 519. Turn on the power switch at the rear of the unit. The yellow light on the front of the 519 will now be illuminated.

If there is no light

Check the power connections, including any fuses in the supply. If the light is still not illuminated, contact your dealer for help.

Basic operation of 519

The 519 Laser Demodulator takes the RF output of a Laser Disc player and extracts the AC-3 data stream. This stream is transmitted via the SPDIF digital audio interface to an AC-3 decoder to be decoded into discrete audio channels.

The 519 will also take the digital audio output of the Laser Disc player, and switch to it when the Laser Disc is not AC-3 encoded. AC-3 decoding is indicated by the red lock light.

The 519 has connections for the Meridian 500 Series Comms system. These connections are used only to communicate with other Meridian equipment. The 519 itself uses these connections only to suppress clicks as it switches between AC-3 decoding and regular digital audio.

Note The Meridian 519 can be used with or without other Meridian equipment. However an AC-3 decoder must be used to obtain an audio output.

Jumper Options

The 519 may be fitted with up to five internal jumpers which will change the way it operates. IN ALMOST ALL INSTALLATIONS NONE OF THESE JUMPERS WILL BE NEEDED. The unit is supplied with no jumpers fitted. It is recommended that the jumpers are fitted only by your dealer.

Opening the Case

WARNING: BEFORE OPENING THE CASE DISCONNECT THE 519 FROM THE AC SUPPLY. BEFORE RECONNECTING THE SUPPLY ENSURE THAT THE CASE IS FULLY REASSEMBLED.

To open the case remove the four screws at the corners of the rear of the 519 and the four screws at the corners of the base of the 519.

Locating the Jumper Positions

There are five sets of two pins each which may be fitted with jumpers. Jumper number 1 is located on the left of the 519 when viewed from the front.

Jumper 1

The Laser Disc RF output signal normally provides an 5 Volt DC signal to indicate that the Disc is playing. When jumper 1 is not fitted the Laser Disc 5 Volt signal is used by the 519 to enable AC-3 demodulation or switching to regular digital audio. If your Laser Disc player does not give the 5 Volt signal fit jumper 1.

Jumper 2

In normal use the 519 will switch to regular digital audio if it is unable to demodulate AC-3. This allows both AC-3 encoded and non AC-3 encoded discs to be replayed with no change of settings by the user. However, fitting jumper 2 tells the 519 not to switch to regular digital audio. In this case, if AC-3 cannot be decoded, the 519 will produce a silent digital audio output at 48kHz sampling rate.

Jumpers 3-5

These jumpers allow the system address for the Meridian 500 Series Comms to be changed:

System Address	Jumper 3	Jumper 4	Jumper 5
1	×	×	×
2	√	×	×
3	×	√	×
4	√	√	×
5	×	×	√
6	√	×	√
7	×	√	√
8	√	√	√

Help!

Yellow power light not lit

Check the following:

1. There is AC power connected to the socket on the rear of the 519.
2. The power switch on the rear panel of the 519 is turned on.

If the yellow light will still not illuminate, check any fuses in your power supply and the fuse in the inlet of the 519. If these are all intact, contact your dealer.

Red lock light not lit

Check the following:

1. The Laser Disc RF output is connected to the RF input of the demodulator

2. The Laser Disc is playing.

3. The Laser Disc is AC-3 encoded.

If the Laser Disc player in use does not produce a 5V DC signal, this will prevent the 519 from decoding AC-3. To overcome this fit jumper 1.

No audio from AC-3 Decoder

Check the following:

1. The yellow and red lights are lit on the 519 (see above).
2. The audio system is able to replay non AC-3 sources (e.g. CD).
3. The 519 digital audio output (either cable or optical) is connected to the AC-3 decoder.
4. The correct physical input of the AC-3 decoder is selected.

No audio when playing a Laser Disc which is not AC-3 encoded

Check the following:

1. The yellow light is lit on the 519.
2. The audio system is able to replay non AC-3 sources (e.g. CD).
3. The 519 digital audio input (either cable or optical) is connected to the Laser Disc player.
4. The 519 digital audio output (either cable or optical) is connected to the AC-3 decoder.
5. The correct physical input of the AC-3 decoder is selected.
6. Jumper 2 is not fitted.

If the Laser Disc player in use does not produce a 5V DC signal, this will prevent the 519 from selecting its digital audio inputs. To overcome this fit a jumper in position 1.

Audible clicks or thumps when pressing play, stop or pause on the Laser Disc

If you are using a Meridian AC-3 decoder or Meridian Digital speakers, the 500 Comms system will help to reduce any clicks. Check that the Comms lead is in place.

If you are not using a Meridian 565 decoder, there may be some clicks as the 519 switches to and from its digital audio inputs. If the digital audio inputs are not in use, fit Jumper 2 to reduce the clicks.
