This uses a negligible amount of electricity, but ensures that the components of the Digital to Analogue Converter operate at maximum efficiency from the moment you start using it. If you are not going to use the Digital to Analogue Converter 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. Eq Lock 44kHz D1 D2 Lock and 44kHz indicators The Digital to Analogue Converter will automatically lock to the input signal providing it is in the correct range, and the Lock indicator will be illuminated. Using the Digital to Analogue Converter To select the input q Press the appropriate key D1, D2, D3, or Opt to select the input you want. An indicator shows the currently-selected input. The digital input D1 is automatically selected when the Digital to Analogue Converter is first switched on. In addition, if the input is from a 44. 1kHz source, such as the 500 Compact Disc Transport, and the signal is within tolerance, double lock will be achieved and the 44kHz indicator will be illuminated. Eq Lock 44kHz D1 D2 9 Preemphasis and phase Eq indicator The compact disc specification allows for a disc to be recorded with preemphasis, which for some types of material can give lower noise levels. The 566 24-Bit Digital to Analogue Converter will automatically correct for preemphasis on playback, and the Eq indicator will Using the Digital to Analogue Converter Phase The 566 24-Bit Digital to Analogue Converter allows you to change the absolute phase of the output signal; in some circumstances this can give a noticable improvement in realism. To change the phase q Press the Phase key. The Phase indicator is illuminated when positive phase is selected. be illuminated whenever material with preemphasis is being played. Eq Lock 44kHz D1 D2 10 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. If it is not, do not try to install the Digital to Analogue Converter, and contact your dealer. You should not make any connections to the Digital to Analogue Converter or to any other component in your system whilst the AC power supply is connected and switched on. Unpacking The 566 24-Bit Digital to Analogue Converter comes in a box containing the following components: r 566 24-Bit Digital to Analogue Converter. r 1 optical connector blanking plug. Setting up the Digital to Analogue Converter In common with all digital equipment, the Digital to Analogue Converter emits some radio-frequency signals. Therefore, you should try to keep all power cables and network leads away from signal cables, including audio, antenna, and loudspeaker cables. Radio interference FCC Warning: This equipment generates and can radiate radio frequency energy and if not installed and used correctly in accordance with our instructions may cause interference to radio communications or radio and television reception. It has been type-tested and complies with the limits set out in Subpart J, Part 15 of FCC rules for a Class B computing device. These limits are intended to provide reasonable protection against such interference in home installations. r 1 500 comms lead. You are advised to retain the packing in case you need to transport the unit. To position the Digital to Analogue Converter Do not place the Digital to Analogue Converter: EEC: This product has been designed to comply with the limits r In direct sunlight. If you are using the 566 24-Bit Digital to Analogue Converter in conjunction with a 501/501V Control Unit or 502 Analogue Controller you can configure the Digital to Analogue Converter Setting up the Digital to Analogue Converter The corresponding indicator will flash: Eq Lock 44kHz D1 D2 q Using the Meridian System Remote, select the source that should select this input; for example, CD. q Press the key corresponding to the next digital input you want to configure, followed by the next source you want to associate with it, and repeat for any other sources you want to configure. so that it uses the COMMS signal to select the correct input automatically when you choose a particular source on the Control Unit. To configure the Digital to Analogue Converter q Connect the 566 24-Bit Digital to Analogue Converter to the other 500 Series units, making sure you connect the COMMS sockets; see To connect to other Meridian 500 Series equipment, page 14. q Switch off the Digital to Analogue Converter, using the power switch on the back panel. q Switch on the other units in the system. q Switch on the Digital to Analogue Converter while holding down the key corresponding to the first digital input you want to configure; for example D2. When you have programmed all the sources you want to configure: q Press Phase to return the Digital to Analogue Converter to normal operation, or switch it off using the power switch on the back panel. 16 Note that you should not configure any of the analogue sources connected directly to the Control Unit in your system. [. . . ] No responsibility can be accepted for the Digital to Analogue Converter whilst in transit to the factory or an agent, and customers are therefore advised to insure the unit. When seeking service under guarantee, proof of the date of purchase will be required. This guarantee does not limit your statutory rights within the United Kingdom. Converter has been subject to misuse, accident, or negligence, or has been tampered with or modified in any way without the written authorisation of Meridian Audio Limited. [. . . ]
