CLEANING
A. Chassis and glass
Use only a soft, lint-free cloth, dampened slightly with water only (NO cleaning fluids!), to clean the faceplate,
chassis and tube chimneys of the A-2000 SE.
B.
Connectors
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 A-2000 SE needs to be placed on a solid stand in a location that
provides good air circulation around, above and below the A-2000 25
th
Anniversary SE stereo power amplifier.
•
DO NOT cover the top of the A-2000 SE.
•
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 A-2000 SE on some kind of after-market isolation feet or similar devices.
Dropping one side of the A-2000 SE, 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, inter-connects and speaker cables. The A-2000 is a highly
sensitive piece of electronic designed for neutrality and will output what you put into it. Allnic’s Zero Loss
Technology cables will work synergistically with the A-2000 SE.
•
DO try to place A-2000 away from major sources and potential receivers of RFI and EMI. Though well
shielded, the A-2000 SE 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.
•
When the unit is moved from a cold to a warm environment, allow sufficient time for any condensation to
evaporate before plugging the A-2000 SE into an AC connection.
•
Do not attempt any repairs.

INPUTS
There are two (2) pairs of female inputs for each channel. One pair accepts balanced cables with a male XLR
connector; the other pair accepts cables with a single-ended, RCA type male connector. These input connections are
located on the right (facing the back) rear of the chassis, with the balanced inputs closest to the side edge. Between
the inputs, there are two (2) switches to select one of two pin configurations for each of the balanced cable pairs
(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). The top connection for each pair of inputs is for the left channel.
