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 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 
function  best  away  from  large  power 
transformers  and  other  sources  of  such 
interference  and  from  other  equipment  that 
could  be  susceptible  to  such  forms/sources  of 
interference. 

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 
return of the unit to the factory for re-wiring, at the 
owner’s cost, including transport both directions.
