INITIAL SET-UP
A.
LOCATION, LOCATION, LOCATION
Like all audio products using tubes, the Allnic Audio T-1800 needs to be placed on a solid stand in a location that
provides good air circulation around, above and below the stereo amplifier.
•
DO NOT cover the top of the T-1800.
•
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 T-1800 on some kind of after-market isolation feet or similar devices.
Dropping one side of the T-1800, 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 T-1800 is a highly
sensitive piece of electronic designed for neutrality and will output what you put into it.
•
DO try to place T-1800 away from major sources and potential receivers of RFI and EMI. Though well
shielded, the T-1800 will function best away from large power transformers and other sources of such
interference and from other equipment that could be susceptible to/sources of such forms of
interference.
B.
INPUTS
There are four (4) RCA type female input pairs and one (1) female balanced (XLR) input pair. Facing the rear of the
chassis, the input connections are to the right of the IEC power input and the Pre Out terminal pair. The left channel
connector is the top one in each line input pair. Please refer to Figure 2.
You can use the T-1800 with a separate preamplifier by connecting the outputs of the preamplifier to one pair of the
T-1800’s inputs
.
HOWEVER, please use caution when you do this.
If you have both volume controls above zero on
turn on, especially with signal, you could damage your speakers because of the extreme volume level from the
combined gain of both the preamplifier and the T-1800.
On initial turn on with a separate pre-amp, you should
have the volume on BOTH units set to zero. Then use the volume control on both the pre-amp and the T-1800 to set
the volume control on the T-1800 so that you can use preamplifier volume control as the main volume control – OR
vice versa, as you prefer.
C.
PRE OUT CONNECTIONS
The T-1800 has a pair of RCA type female Pre Out (Preamplifier outputs – refer to Figure 2) connections on the rear
of the chassis, between the IEC connection and the Line Inputs. The Pre Outs are connected actively; therefore,
when they are in use, the EL34s continue to draw power and operate. These connections are intended especially for
connection to one or a pair of powered subwoofers. However, it is also possible to use them to connect to an
external stereo power amplifier or pair of monoblock amplifiers (preferably with the same gain as the T-1800).
