Unpacking
The content should include:
• Hq9038 - TUBE DAC
• Remote Control
• This User Manual
Retain the packing for safe transport of your unit.
Avoid allowing static shocks to be applied to the inputs or
outputs. To prevent static shocks, touch any grounded
surface, such as the DACs chassis, before connecting or
removing a cable. It is unlikely that a static shock will
damage the unit, but it may cause circuitry to “lockup”.
Inputs and outputs can be safely connected to the DAC
unit before it is powered up.
We strongly recommend that you use your DAC unit directly
to your power amplifier. Even if you purchased your DAC
unit with the intention of connecting it to your preamplifier,
we suggest that you try direct connection to your amplifier.
Many listeners are surprised by the
improvement in performance over even the most
expensive preamplifiers.
To connect your DAC unit to a power amplifier, ensure that
your power amplifier is turned off then connect your analog
interconnects from the DACs analog outputs to the
amplifier’s inputs.
Connecting to the Mains
Check to make sure your DAC unit has been manufactured
for operation at your AC line Voltage. Attempting to use the
DAC at any voltage other than the specified on the rear of
the unit may damage the unit. Damage caused by
improper operation is not covered by warranty. If the
voltage specified is different from your AC voltage, contact
your dealer..
Placement
The unit is designed to run warm during normal operation
but ensure you do block any ventilation openings.
Place the unit on a shelf or table. If you use an equipment
Rack ensure the unit has adequate ventilation and is on its
own shelf. Ensure your mains voltage corresponds to the
rating plate on the rear of the unit.
Connecting Directly to a Power Amplifier
While the DAC unit was designed to be used without a
preamplifier, no compromises were made in its design that
will prevent excellent operation in a conventional system
with a preamplifier.
When using a preamplifier, set the DAC units volume control
to its maximum level.
