8 Introduction.
Using the integrated amplifier T his chapter provides a visual summary of the functions of the integrated amplifier in order to identify the controls which you will use to operate the unit. It also describes how to switch on the integrated amplifier, and use it with your audio sources.
Using the integrated amplifier 10 Fr ont panel 1 Source Selects the source. 2 Copy Copies a selected source to the tape output. 3 Spkrs Mutes the power amplifier. 4 Mute Mutes the sound. 5 Display Blanks the display. 6 V (Decrease) Decreases the volume.
Using the integrated amplifier 11 Selecting a sour ce During normal use the integrated amplifier should be left in the standby state. This uses a negligible amount of electricity, but ensures that the components of the integrated amplifier operate at maximum efficiency from the moment you start.
Using the integrated amplifier 12 Adjusting the volume To mute the sound ● Press Mute . The display will show: Mute To restore the sound ● Press Mute again. Alternatively the sound will be restored if you adjust the volume. To mute the loudspeakers ● Press Spkrs (front panel only).
Using the integrated amplifier 13 Changing the display and balance To change the display ● Press Display . Each time you press Display the display will step between the following options: Display option Example Source and volume. This is the usual display.
Using the integrated amplifier 14 Recording a sour ce For example, to record a radio broadcast press Copy until the display shows: C RD You can now listen to a CD, by selecting the CD source, without affecting the recording.
Customising the integrated amplifier T his chapter explains how to customise the 551 Integrated Amplifier to your preferred configuration. The simplest way of configuring the integrated amplifier is to choose one of the standard settings, which are designed to cater for the six most common configurations of sources and inputs.
Customising the integrated amplifier 16 Choosing standar d settings The 551 Integrated Amplifier provides six alternative standard settings, called Types, which configure all aspects of the integrated amplifier into the six most commonly needed configurations.
Customising the integrated amplifier 17 Standard settings The following table shows the options configured by the six standard Type settings on the 551 Integrated Amplifier: Type 5143 Source Label Inp.
Customising the integrated amplifier 18 Configuring the sour ces When the integrated amplifier is set to one of the standard settings the twelve source selection keys on the remote select the standard labels and inputs, as shown in the table on page 17.
Customising the integrated amplifier 19 To change an option ● Press A or V to step between the alternative values for the option. When you have finished programming sources: ● Switch off at the back panel, and then switch on again to restore normal operation.
Customising the integrated amplifier 20 The following examples illustrate how you can configure the source options to your own requirements. To change a source label ● Display the source you want to configure, together with its current label, as described in the previous sections.
Customising the integrated amplifier 21 To set up a system with two CD players ● Configure the source you are going to use for the first CD player. For example: Source CD, Label C1, Audio input A2, Comms type 1C, Address 1A. ● Configure the source you are going to use for a second CD player, with a different address.
Customising the integrated amplifier 22 Pr ogramming levels The 551 Integrated Amplifier allows you to program the level of each source independently, to suit your other equipment, so that when you switch between sources the volume stays the same.
Customising the integrated amplifier 23 ● Use the A and V keys to change the sensitivity. For example, the display will show: 12dB ● Switch between the source you are changing and the reference source until they sound equally loud. ● Repeat the procedure for your other sources.
Customising the integrated amplifier 24 In addition to configuring the sources, and programming their levels, you can configure many other aspects of the operation of the 551 Integrated Amplifier to suit the way your system is set up, and the way in which you want to use it.
Setting up the integrated amplifier T his chapter explains how to install the 551 Integrated Amplifier. It describes what you should find when you unpack the integrated amplifier, how you should connect it to your other audio equipment, and the siting constraints.
Setting up the integrated amplifier 26 Unpacking The 551 Integrated Amplifier comes in a box containing the following components: ❍ 551 Integrated Amplifier. ❍ 1 power cord. ❍ 1 500 Series communications lead. ❍ This manual. You are advised to retain the packing in case you need to transport the unit.
Setting up the integrated amplifier 27 Back panel Connecting the integrated amplifier Use this input To connect to this A1 A turntable pickup with optional MM/MC module.
Setting up the integrated amplifier 28 The following table gives details of the audio outputs: Use this output To connect to this Right/Left Output Loudspeakers of 4 Ω to 15 Ω , using either banana plug or bare wire connections. Pre-amp Out An additional power amplifier or active loudspeakers.
Setting up the integrated amplifier 29 This is the unit that will respond to the remote. All the other units will be configured as non-controllers, and display: NCon Your system is now set up and ready for use.
Setting up the integrated amplifier 30 ● Switch the power off and on again to restore the integrated amplifier to normal operation. ● To return to 500 COMMS operation repeat the above procedure, and select Type 1, 3, 4, or 5. For more information see Choosing standard settings , page 16.
Setting up the integrated amplifier 31 T roubleshooting This section describes problems you may encounter when using the integrated amplifier, and includes suggested solutions. If these suggestions fail to cure the problem, please contact your Meridian dealer for further assistance.
Setting up the integrated amplifier 32 Communication is not working between the 551 Integrated Amplifier and other Meridian products ❍ Check that all products are interconnected using the correct comms leads. ❍ If the installation includes 200 Series or 600 Series units, check that all 500 Series units are set to 200 mode.
Setting up the integrated amplifier 33 To clean the audio connections The audio sockets on the back of the integrated amplifier are gold-plated and need no cleaning if gold-plated phono plugs are used. Otherwise, it is recommended that you unplug and reconnect the plugs at least once a year.
Setting up the integrated amplifier 34 Service and guarantee Service The Meridian 500 Series of hi-fi components have been carefully designed to give years of untroubled service. There are no user- serviceable parts inside the case, nor do the units require any form of maintenance.
