INITIAL SET-UP
A.
LOCATION, LOCATION, LOCATION
Like all audio products using tubes, the Allnic
Audio L-7000 needs to be placed on a solid
stand in a location that provides for good air
circulation around the preamplifier.
•
DO NOT cover the top of the L-7000
preamplifier.
•
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 L-7000 on some kind of
after-market isolation feet or similar
devices. Dropping one side of the
L-7000, or the whole 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 unit's 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 and inter-connects, both
inputs and outputs. The L-7000 is a
highly sensitive piece of electronic
equipment designed for neutrality and
will output what you put into it.
•
DO try to place the L-7000 away from
major sources of RFI and EMI; though
well shielded, the L-7000 will function
best
away
transformers and other sources of
such interference.
B.
POWER CONNECTION
The L-7000 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.
To the left of the IEC connector (facing the left
side of the unit as in Figure 1), there is a power
on-off switch. Leave this switch in the OFF
position – that means the switch is pressed
"down" at the bottom - while you make all
initial connections.
The L-7000 you have purchased is set
internally for AC 110 or 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.
C.
INPUTS
There are five (5) inputs. Line 1 and Line 2 are
balanced connections (XLR type connectors).
The remaining 3 line inputs are RCA type
single-ended connections. None of the inputs
is intended especially for connection to any
particular device.
NO PHONO STAGE - The L-7000 is a line stage
preamplifier and does NOT have a built in
phono preamplifier section. You will need a
phono preamplifier if you want to use a
turntable with the L-7000. You can connect
your phono preamplifier to any of the five
inputs, provided you have the appropriate
types of connections or adaptors.
