INITIAL SET-UP
A.
LOCATION, LOCATION, LOCATION
Like all audio products using tubes, the Allnic Audio M-
3000 MK2 needs to be placed on a solid stand in a
location that provides good air circulation around,
above and below the monoblock.
•
DO NOT cover the top of the M-3000 MK2.
•
DO NOT place the unit on carpet or foam.
•
DO NOT subject the unit to knocks and shocks
as you move it around. This advice is meant
particularly for those who may want to place
the M-3000 MK2 on some kind of after-market
isolation feet or similar devices. Dropping one
side of the M-3000 MK2, or the whole of the
unit, is not a good thing to do.
•
DO NOT place the unit near a strong light or
heat source.
•
DO NOT place anything heavy on the unit.
•
DO NOT allow rubber or vinyl materials to rest
on the chassis for long periods of time. This
could discolour the metal.
•
DO place the unit on a shelf or stand that is
stable and not subject to vibration or sudden
shock.
•
DO consider using a high quality power cord,
interconnects and speaker cables. The M-
3000MK2 is a highly sensitive piece of electronic
designed for neutrality and will output what you
put into it.
•
DO try to place M-3000 MK2 away from major
sources and potential receivers of RFI and EMI.
Though well shielded, the M-3000 MK2 will

B.
INPUTS
There are two (2) female inputs. One accepts a balanced
cable with a male XLR connector; the other accepts a
cable with a single-ended, RCA type male connector.
These input connections are located on the right rear of
the chassis, with the balanced input closest to the side
edge. Between the inputs, there is a switch to select one
of two pin configurations for a balanced cable (i.e., it
changes the phase). The top position is for pin 2" hot"
and pin 3 "cold"; the bottom position is for the reverse
(in both cases, pin 1 is ground). Please refer to Figure 4.
C.
SPEAKER TERMINALS
The M-3000 MK2 is equipped with one pair of high-
quality speaker terminals. These terminals are located
in the middle of the rear panel of the M-3000 MK2
chassis, with the terminal for the live connection
marked positive "+" on the left, and with the return
connection labeled negative "-", to the right (facing the
chassis rear). Between the plus and minus terminals is a
switch that provides for either 8 or 4 ohm impedance,
as your speakers may require. The upper position of the
switch is for 8 ohm operation; the lower for 4 ohm
operation. 8 and 16 ohm terminals are available by
special order. The terminals accept bare wire (not
recommended) and spade and banana type connectors.
D.
POWER CONNECTION
Connect the input interconnect and speaker cables
before you insert the power cable into the
receptacle at the left (facing the back) rear of the
chassis. The M3000 MK2 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 M-3000 MK2 you have purchased is set
internally for AC 220 volt – 60 HZ operation. There is
no way to change this to another AC setting without
power
return of the unit to the factory for re-wiring, at the
owner's cost, including transport both directions.
