You may use any good quality contact cleaner
recommended for such applications to clean the contacts
from time to time, as you deem appropriate.
INITIAL SET‐UP
A.
LOCATION, LOCATION, LOCATION
Like all audio products using tubes, the Allnic Audio H‐3000
and its power supply need to be placed on a solid stand in a
location that provides good air circulation around both the
phono stage and the power supply.
•
DO NOT cover the top of the H‐3000 phono stage or
the ventilation slots in the top of the power supply
chassis.
•
DO NOT place the units on carpet or foam.
•
DO NOT subject the units to knocks and shocks as you
move them around. This advice is meant particularly
for those who may want to place the H‐3000 or its
power supply on some kind of after‐market isolation
feet or similar devices. Dropping one side of either of
the H‐3000 units, or the whole of either unit, is not a
good thing to do.
•
DO NOT place the units near a strong light or heat.
•
DO NOT place anything heavy on the units.
•
DO NOT allow rubber or vinyl materials to rest on
either units' chassis for long periods of time. This
could discolour the metal.
•
DO place the units on a shelf or stand that is stable
and not subject to vibration or sudden shock.
•
DO consider using a high quality power cord and
inter‐connects, for both inputs and outputs. The H‐
3000 is a highly sensitive piece of electronic designed
for neutrality and will output what you put into it.
•
DO try to place the H‐3000 and its power
supply away from major sources of RFI and
EMI; though well shielded, the H‐3000 units will
function best away from large power
transformers and other sources of such
interference.
B.
POWER CONNECTIONS
The H‐3000 power supply uses a standard three prong
male IEC connection for AC input. You need to use a power
cord with a female three prong IEC connector at one end.
The H‐3000 power supply connects to the phono stage
itself using the supplied umbilical cable. Connect the units
to each other using the umbilical cable with the
appropriate screw‐on connections to the receptacle
labeled "DC Source Input" on the rear of the phono stage
and the connection terminal labeled "DC Source Output"
on the left side of the rear of the power supply (Please
refer to Figures 1 and 2).
The H‐3000 power supply you have purchased is set
internally for AC 110/120 volt – 60 HZ operation. There is
no way to change this to another AC setting without return
of the unit to the factory for re‐wiring, at the owner's cost,
including transport both directions.
C.
INPUTS
There are two (2) sets of two (2) pairs of single‐ended (RCA)
inputs. These two pairs are located in the middle of the rear of
the phono stage (See Figure 1) and labeled "input" in the middle
above them. Each channel pair of inputs is aligned vertically,
with the left channel input at the top and the right channel input
on the bottom. The two left hand pairs of inputs (facing the back
of the phono stage) have an "MC" label above the two left
channel connectors; these are the two input pairs for a moving
coil cartridge. The right hand pair of inputs has an "MM" label
above the left channel connectors; these are the two input pairs
for a moving magnet cartridge. Each pair of moving coil and
moving magnet connections has a number label between the left
and right channel input connections.
In each case, for both MC and MM connections, the left hand
vertically aligned pair of connections (again, facing the back of
the unit) corresponds to input 1 for the button switch on the
front panel of the phono stage , while the right hand vertically
aligned pair is input 2.
Between the two sets of MC and MM input connections is a
