will greatly suffer. Regular cleaning of
these parts with proper materials or
solutions is highly recommended to

 How to connect headphones? - The

headphone output on the front panel is a
standard 6.5mm connection. You may
use a 6.5mm-to-3.5mm adaptor to use
other type of headphones. Alternatively,
you can use a Stereo RCA to Headphone
adapter to convert the Tube Out at the
rear panel to headphone jack then plug
your headphones in. This way, you are
enjoying the DAC-11 as a tube
headphone amp through the 6N11 tube
output stage.

 How to connect with power amplifier? –

When using the Line Out or Tube Out as
your output connection, this product can
be used as a passive preamp to connect
to power amplifiers. Use the DAC-11
volume control as your main volume
control.

 How to Power ON the product? - When

all is connected and you have set the
dual voltage selector switch on the rear,
you should power on your source
components (such as DVD/CD players or
tuners) first, then DAC-11, the last one
is the amplifier. When turning the
system off, the sequence should reverse,
i.e. power off amplifier first, then
