WIDE NARROW MUTE This indicator is lit when the unit detects valid clock at the selected digital audio input For normal operation with digital audio inputs this indicator has to be lit or else all audio outputs will be muted For normal operation with analog audio inputs this indicator will stay off and all audio outputs are unmuted Selects external clock input when lit The actual clock input is then determined by the selected digital input This switch controls the Master and Slave operation as explained in more depth later in this manual For Master operation this switch has to be turned off and for Slave operation it has to be turned on These buttons select the base freguency for the selected digital audio input For instance for all digital inputs with sample freguencies of 44 1kHz or 88 2kHz the switch 44 1kHz has to be selected for all digital inputs with sample freguencies of 48kHz or 96kHz the switch 48kHz has to be selected When this switch is lit the polarity of all analog outputs is inverted These switches are only active when a digital audio input source is selected and are inactive for analog input sources When NARROW bandwidth is selected the analog outputs are lowpass filtered to limit the amount of signal content above 30kHz The WIDE mode selects a much wider bandwidth and should be used in most cases When lit all outputs are muted Pushing the button again unmutes the outputs Analog DSD

5. CD transport clock master and clock slave modes Master slave is in reference to who provides the clock signal to the D A conversion process and who receives an external clock as a guide signal to lock to In clock master mode the DCC2 generates and provides the clock to the D A conversion process and also to the CD transport Of course for this the CD transport has to be eguipped with an external clock input If no such connection is available then the only way to connect the transport to the DCC2 is in clock slave mode The clock master mode will generally provide better sonic performance over the clock slave mode as clock jitter is minimized In clock slave mode the transport provides the main clock and the DCC2 will use itas a reference to lock to For best results you should operate the DCC2 in clock master mode whenever possible The following paragraphs explain master and slave setups in detail for every individual digital source input of the DCC2 AES EBU input In cases where the sample rate is either 44 1kHz or 48kHz there will be only 1 cable with XLR connectors for the audio data Connector 1 on the back of the DCC2 has to be used In cases where the sample rate is either 88 2kHz or 96kHz there are two possible topologies depending on how the source operates e 1 single cable for 2 channels e 2 individual cables for 1 channel each Again if only 1 cable is used it has to be plugged into connector 1 on the DCC2 For the 2 cabl
