DAC6e USER MANUAL Version 1.
DAC6e 6-channel D/A Converter The EMM Labs 6-channel D/A converter is a 4th generation design to meet the highest standards in consumer audio applications. It offers conversion from digital audio of various different formats to analog. For best audio performance the DAC6e should be operated in Master Clock mode. Features • 6-channel conversions: • from PCM (44.1kHz, 48kHz, 88.

Clock Section INT / EXT: Selects internal or external clock source. LOCK LED is lit when D/A converter is locked to external clock. When in INT, the DAC6e generates the master clock signal (master clock mode) for the audio source. Connect either the BNC or optical clock output from the DAC6 to your audio souce. When in EXT (slave clock mode) no additional connection from the DAC6e to the audio source is required. Sample Rate Section 1FS / 2FS: Selects the sample rate for PCM data.
Up to 3 AES/EBU cables can be connected to the DAC6e. The 4 possible audio frequencies can be selected according to Table 1: In the case of 2FS operation (88.2kHz or 96kHz) the clock rate of the trans- Table 1: Selection of Audio Sample Rates Sa mple R ate S wi tc h Switch 44.1kHz 1FS 44.1kHz 4 8k H z 1FS 48kHz 88.2kHz 2FS 44.1kHz 9 6k H z 2FS 48kHz mission on the cable is double. Master / Slave clock operations can be selected with the INT / EXT switch (see below for more detail).
Master and Slave Clock Operation In Master mode (switch set to INT) the DAC6e provides the clock to the audio source. A cable needs to be connected from either the BNC Clock output or Optical Clock output from the DAC6e to the clock input of your audio source. This mode provides the best audio performance as the clock jitter is minimzed. In Slave mode (switch set to EXT) the DAC6e locks to the clock as provided by the selected audio source (DSD or PCM).
Warranty EMM Labs warrants the DAC6e product against defects in material and workmanship under normal use and service for a period of time specified by the product’s serial number from the date of first delivery to the owner. The warranty time period is 5 years limited to the original owner. EMM Labs will pay for return shipping charges back to the owner when the product is sent to EMM Labs within first 90 days after purchase.
