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, 88.2kHz, 96kHz) to analog
• from DSD to analog
• Supported input formats:
• AES/EBU (3 connectors) for PCM
• ST Fiber optic for DSD
• Master and Slave Clock Operation
• Power supply
• power factor corrected
• auto ranging 85V - 240V, 50/60Hz
• power consumption: 60W
• Analog outputs
• balanced on XLR
• unbalanced on RCA
• Analog output impedances
•100Ω balanced, 50Ω unbalanced
Note: XLR analog outputs are balanced with pin 2 hot, pin 3 cold and pin 1 GND.
Function Switches
Power
The main power switch is on the back of the unit. The chrome power button
on the front is a momentary switch that toggles the operation between power
on and power save modes every time the user pushes it.

selected with the INT / EXT switch (see below for more detail). In Slave
operation there has to be at least an AES/EBU cable connected to channels
1/2 as this connection provides the clock for the DAC6e.

The optical interface format requires 2 cables: 1 for clock and 1 for audio
data. They both need to be connected regardless of what clock mode is
selected (master or slave). This mode requires the selection of 44.1kHz
base frequency. Master / Slave clock operations can be selected with the
INT / EXT switch (see below for more detail) and the 1FS / 2FS switch is
ignored.

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).
Channel assignment when using EMM OptiLink to connect a CDSD to the DAC6e
The CDSD can play back up to 6 channels from SA-CD when combined with
the DAC6e converter. In this case the analog output channels of the DAC6e
have the following channel assignment:
Channel 1: Left front
Channel 2: Right front
Channel 3: Center front
Channel 4: Low Frequency Subwoofer
Channel 5: Left rear surround
