The RS-232 communication connectors are for connection to a computer for fi rmware upgrade. Please visit www .lyngdorf.com for instructions and available[...]

9 Remote Control The remote control is used to access the menu system and replicate the buttons directly accessible on the front panel. The four buttons used for selecting which device to control are described below . T o control the Millen- nium ADC the AMP key should be pressed. The functionality of the remote control depends on the products in y[...]

10 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 Mill[...]

12 Menu Operation In the following the general menu operation is described with Display T imeout menu (used as an exam- ple only). The menus available depend on the selected input. All settings outside the common menus apply to the selected input only . Please refer to the menu tree. When The Millennium ADC is switched on select the menu by pressin[...]

13 Common Menus Digital Sample Rate A vailable 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 [...]

14 Phono Input Menus High Pass Filter The high pass fi lter can be chosen to fi lter away rumble and/or acoustic feedback. A vailable 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. S[...]

15 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-loa[...]

16 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 sensiti[...]

17 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 corre[...]

18 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 [...]
