Output Connections
We strongly recommend that you use the Balanced XLR output to drive your e.One amplifier. Because of the DC
coupled nature of the DAC3 there is a small residual DC offset on the outputs. This is typically less than 10mV
(0.01 Volts) and will be compatible with any Bel Canto amplifier or any vacuum tube or solid state amplifier with
AC coupling or DC servo control. If using a Bel Canto preamp there will be no small click or pop when selecting
the input. Other preamplifiers that do not ramp the volume up or down may produce a small click when selecting
the DAC3 input.
Power Up
We recommend leaving the DAC3 powered at all times
as the sonic quality is best after several hundred hours
of play.
Connection to a Computer
The USB port can be used for up to 16/48 data, enough for any CD source. For connection at 24/192 or higher
data rates, we recommend using a quality sound card with SPDIF, AES/EBU or glass TOSLINK connection. For

What to do if there is hum or ground noise
The design of the DAC3 greatly reduces the chance for ground loop induced hum and noise. We recommend
using the balanced outputs for best performance-the balanced outputs can drive long lines to 10 meter length.
Connect all power cables of the audio system to a common outlet box or power conditioner unit. Having the
audio system components share a common ground will greatly reduce the possibility for ground current noise
being introduced into the audio signal path.
