Do I need to solder anything?
Q No! we have pre-fixed everthing for you. It’s
Ajust a matter of assembling all the parts with a
few basic tools.
What kind of quality can I expect from this
QDIY PreAmplifier kit?
I do not have any technical experience,
Qcan I build this amplifier kit myself?
Yes! even without any technical experience you
Acan build your own amplifier kit.
A In basic this PreAmplifier works with all power
amplifiers, certainly DIYclassD power amplifier
kits.
Hypex Electronics is known for her outstanding
Asound quality, this DIY PreAmplifier kit
represents that quality for DIYclassD.com as
well. You may expect outstanding performance
in a DIY format.
Do you offer a pre-assembled Pre Amplifier
Qkit?
A No, we only offer a DIY building kit. We do not
offer any further assembly services.
Does this DIY PreAmplifier work with my
Qpower amplifier?
Frequently asked
questions
Ÿ Check all the cables.
Poor sound or noise
Ÿ Use balanced connections for best system
performance.
Ÿ Use grounded wall sockets.
Ÿ Check the power outlet.
Ÿ The internal fuse may be blown. This fuse is not
user replaceable. Please contact Hypex
Electronics for more information about service
and repair.
No Sound
Ÿ A protection might be triggered. Is the module
overheated? Try cycling the mains power.
No power
Ÿ Check the source signal.
Ÿ Check optional trigger settings.
Ÿ Check if the signal is not inverted. Inverted
signals might cause one of your speakers to be
out-of-phase.
Ÿ Check the volume and mute settings.
Ÿ Is the amplifier clipping?
Ÿ Check all connections.
Hum
Ÿ Check if Headphones are activated.
Ÿ The AC-Terminal fuse may be blown. Disconnect
power cables and determine its status. If blown:
check all AC-cables for damage and correct
connections and fix problems. Replace the fuse
with a corresponding one.
Heat
Balanced/unbalanced connections
Ÿ The Pre Amplifier kit is equipped with balanced
and unbalanced inputs. If all the unbalanced
inputs are already in use and your source does
not provide a balanced output but only an
unbalanced output you can use one of our
interconnects to connect both properly.
Ÿ The Pre Amplifier Kit will get warm/hot when
used intensively, this is normal and therefore no
reason for concerns.
