Unpacking the Millennium ADC Carefully remove the unit and accessory kit from the carton, visually check for shipping damage. Contact both the shipper and your Lyngdorf Audio dealer immediately if the unit bears any sign of damage from mishandling. All Lyngdorf Audio equipment is carefully inspected before leaving our factory. Keep shipping carton and packing material for future use or in the unlikely event that the unit needs servicing. If this unit is shipped without the original packing,

Placement The Millennium ADC should be placed well away from any source of magnetic fi elds like wall mains adapters. Also avoid placing on top of a power amplifi er – instead place them ‘side by side’. Figure 3. Recommended placing of the Millennium ADC. Millennium Link Connection By using the Millennium Link Connection between the Millennium ADC and a Millennium MkIII or MkIV amplifi er (from fi rmware version 40) you are ensured the best possible integration of the two products – both in terms

Common Menus Digital Sample Rate Available sample rates are 48, 96 and 192 kHz. Choice of sample rate depends on the compatibility with the actual amplifi er. If your amplifi er accepts all sample rates, we recommend you to test the different settings to fi nd your personal preference. This is due to the fact that there is no simple answer as to what will result in the ‘absolute best sound’ – simply because it depends on many unknown parameters such as the recording, the source, the complete a

Phono Input Menus High Pass Filter The high pass fi lter can be chosen to fi lter away rumble and/or acoustic feedback. Available settings are 10, 15 or 20 Hz. This is referred to as the F2 point in fi g. 4. De-emphasis Records made before 1955 were recorded with different emphasis curves, requiring different de-empha- sis during playback. Some records specify the emphasis curve used on their cover, but in many cases you have to make an educated guess based on record label and year of release. A

Setup Cartr.: 1 Load Preset If you use one of the pre-loaded cartridges you can load this directly which then automatically sets up the ADC to this cartridge (gain, capacitance, impedance and DSP cartridge fi lter). If you have a different cartridge, you need to make these settings manually. If you at a later stage wish to de-select a pre-loaded cartridge, simply select ‘Default’ in this menu to set this cartridge back to the factory default settings. DSP Cart.

Input sensitivity versus cartridge output specifi cation The output voltage of cartridges are generally specifi ed at a stylus velocity of 5 cm/sec. High performance turntable/tone arm/cartridge combinations can track up to 50-75 cm/sec resulting in an output of 10 to 15 times the output voltage specifi ed for the cartridge. The input sensitivity specifi ed for the Millennium ADC is the voltage required for full-scale output. In the guide (fi g 5) we have calculated the settings with a track abil

Cartr. Balance The Cartridge Balance adjustment enables you to compensate for differences between left and right channel. The balance is adjusted by decreasing the left or right channel between 0 - 3dB. Cartr. Capacit. The cartridge capacitance can be set to 100 or 430pF. Pls. refer to the specifi cation of your cartridge to fi nd the correct setting. For MM cartridges start with 100pF. If this setting sounds too ‘bright’, use 430pF. For MC cartridges use 430pF unless otherwise specifi ed. Cartr

Analog Input 1- 4 Menus Input Gain The Input Gain enables you to match levels from different sources as well as obtaining full scale output on your amplifi er. The Input Gain can be adjusted up to +18dB in 0.1 dB steps. Please refer to the output level specifi cations of the source and then use the table in fi g. 6 as a guide when adjusting relative input gain. Setting the Input Gain too high will result in distortion. Use the table below as a guide but always use your ears when setting the In
