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 DAC3.5
VB there is a small residual DC offset on the outputs. This is typically less than
10mV (0.01 Volts) and will not be a problem for any Bel Canto amplifier or any vacuum tube or solid state
amplifier with AC coupling or DC servo control. There is no problem connecting the DAC3.5VB to any preamplifier.
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 DAC3.5
VB input.
Power Up
We recommend leaving the DAC3.5VB powered at all times as the sonic quality is best after several hundred
hours of play and 48-72 hours of power on after the initial break-in time.
Connection to a Computer
For connections up to 24/96, use the USB out of your computer to connect into the DAC3.5
VB via either the USB
Link 24/96 or the USB Light Link 24/96. For more details on optimizing computer audio sources please refer to

What to do if there is hum or ground noise
The design of the DAC3.5
VB 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. 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.
Volume Control Punch Through
The Volume Up, Down and Mute functions on the remote control will affect any Bel Canto unit in Variable Output
mode regardless of whether PRE, DAC, CD or TUNER is selected. It is recommended that only the device with
volume control closest to the power amps be in Variable Output mode. Any other devices that are capable of
volume control should be in Fixed Volume mode.
