Introduction In choosing the 502 Analogue Controller you have acquired a component that combines major advances in audio and engineering design. The 502 Analogue Controller is a dual mono preamplifier with a fully balanced signal path and an extremely high-quality power supply for ultra low distortion and noise. It provides seven audio inputs; four for sources with unbalanced outputs, and three for balanced sources.
The Meridian 500 Series The Meridian 500 Series is a unique system of digital, analogue, 500 Series communications and video components designed to meet the demand for absolute quality, ease of use, and lasting value. The Meridian 500 Series includes a sophisticated communications link, to ensure that any configuration of units The flexibility of the Meridian 500 Series is such that you can will work together as a fully integrated system.

Using the analogue controller This chapter provides a summary of the functions of the analogue controller in order to identify the controls which you will use to operate the unit. It also describes all aspects of using the analogue controller, from switching on and selecting a source, to recording a source. Unless otherwise specified, each function is available from the front panel or the remote.

Selecting a source During normal use the analogue controller should be left in the By default, the following seven sources are available: standby state. This uses a negligible amount of electricity, but ensures that the components of the analogue controller operate at maximum efficiency from the moment you start. If you are not going to use the analogue controller for a period of several days you should switch the unit completely off, at the back panel, and disconnect it from the AC power supply.
Adjusting the volume The 502 Analogue Controller allows you to adjust the volume in To decrease the volume precise steps of 1dB, where 9dB is equivalent to doubling the loudness. ● Press V. The current volume setting is displayed in dB on the front panel For example, the display will show: CD 74 display, and can be varied in the range 1 – 99dB.

Customising the analogue controller This chapter explains how to customise the 502 Analogue Controller to your preferred configuration. The simplest way of configuring the analogue controller is to choose one of the standard settings, which are designed to cater for the three most common configurations of sources and inputs. Alternatively, you can configure each source individually to suit the other equipment in your system.
Choosing standard settings The 502 Analogue Controller provides three alternative standard To select a standard setting settings, called Types, which configure all aspects of the analogue controller into the three most commonly needed configurations. Choosing one of the six standard settings overrides any other configuration you may have performed, and so can be used to reset the configuration of the analogue controller. ● Switch off any power amplifiers that are connected to the analogue controller.
502 standard settings The following table shows the options configured by the three standard Type settings on the 502 Analogue Controller: Type Label Input Gain Comms 1 2 3 CD CD A5 0dB 1 ● ● ● Radio RD A3 +2dB 2 ● ● ● LP LP A1 +2dB – ● ● ● TV TV A4 +8dB – ● ● ● Tape1 T1 A2 +2dB – ● ● ● Tape2 T2 A7 +2dB – ● ● ● CDR CR A6 0dB 1 ● Cable Cb A4 +8dB – ● Text TX A4 +8dB – ● VCR1 V1 A2 +8dB – ● VCR2 V2 A7 +8dB – ● LD LD A1 +0d

Programming levels The 502 Analogue Controller allows you to program the level of To balance input levels each source independently, to suit your other equipment, so that when you switch between sources the volume stays the same. ● Switch off any power amplifiers that are connected to the analogue controller. When you are programming levels the analogue controller operates as a preamplifier with a fixed volume setting equivalent to 65. This level is chosen to be comfortably loud on average sources.
● Use the A and V keys to change the sensitivity. If you know the output level of your sources you can probably set the gains by calculation. The following table shows the LP -4dB correspondence between the gain and sensitivity on the standard audio inputs and on the LP inputs: ● Switch between the source you are changing and the Gain A2-A7 LP MM LP MC -15dB 840mV 17mV 1.2mV -10dB 470mV 9.5mV 660µV -5dB 270mV 5.3mV 380µV 0dB 150mV 3mV 210µV 5dB 84mV 1.

Setting up the analogue controller This chapter explains how to install the 502 Analogue Controller. It describes what you should find when you unpack the analogue controller, how you should connect it to your other audio equipment, and the siting constraints. Before you begin installation, you should ensure that your analogue controller is the correct voltage for your local AC supply. If it is not, do not try to install the analogue controller, and contact your dealer.
