Setting up the Digital to Analogue Converter This chapter explains how to install the Digital to Analogue Converter. It describes what you should find when you unpack the Digital to Analogue Converter, how you should connect it to your other audio equipment, and the siting constraints. Before you begin installation, you should ensure that your Digital to Analogue Converter is the correct voltage for your local AC supply.
Unpacking The 566 24-Bit Digital to Analogue Converter comes in a box In common with all digital equipment, the Digital to Analogue containing the following components: Converter emits some radio-frequency signals. Therefore, you should try to keep all power cables and network leads away ❍ 566 24-Bit Digital to Analogue Converter. from signal cables, including audio, antenna, and loudspeaker ❍ 1 power cord. cables. ❍ 1 digital cable.
Connecting the Digital to Analogue Converter Back panel Input Description D1, D2, D3 The diagram below shows the back panel connections. Unbalanced phono at 75Ω, for use with SPDIF or AES/EBU standard signals. Digital inputs AES/EBU D1 XLR connection on D1, for AES/EBU standard signals. Note that if this input is used D1 must be left unconnected. alternative digital inputs, selectable from the front panel, and Optical EIAJ these support three different digital input standards.
Analogue outputs The sequence in which you connect the units is not important. The following two alternative audio outputs are provided: Note: Do not, under any circumstances, connect any equipment Setting up the Digital to Analogue Converter other than Meridian 500, 600, or 200 Series to the socket 14 Output Description Output Unbalanced analogue output, 2V marked COMMS on the back of the 566 24-Bit Digital to nominal, on RCA phono pair.
To connect to a 502 Analogue Controller 502 Analogue Controller 566 24-Bit Digital to Analogue Converter CD BALANCED OUTPUTS ● Connect one of the digital inputs D1, D2, or D3 on the back panel of the 566 24-Bit Digital to Analogue Converter to the digital output of the other equipment, using a digital lead.
Configuring the Digital to Analogue Converter The Digital to Analogue Converter is initially set up so that you The corresponding indicator select the digital input you want by pressing the appropriate key will flash: Eq Lock 44kHz D1 D2 on the front panel.
Note that you should not configure any of the analogue sources connected directly to the Control Unit in your system. Otherwise selecting one of these will change the digital input on the Digital to Analogue Converter which could interrupt a source you are tape recording. You can reset the Digital to Analogue Converter to its initial configuration using the following procedure: ● Turn off the Digital to Analogue Converter, using the power switch on the back panel.
Troubleshooting This section describes problems you may encounter when using There is no Lock light the 566 24-Bit Digital to Analogue Converter and includes suggested solutions. If these suggestions fail to cure the problem, please contact Setting up the Digital to Analogue Converter your Meridian dealer for further assistance. 18 No lights are displayed when switching on ❍ Check that your AC power supply is connected correctly. ❍ Check that one of the source indicators is lit.
