IMPORTANT READ THESE NOTES THROUGH FIRST!
2 QUICK SET UP GUIDE
1 Unpack unit carefully
. Make sure that it is in
good condition. If not report to Icon Audio. It is
important
that
you
keep
packaging
for
warranty/service return.
2 If necessary fit the valves, or check that they
are firmly in place.
The big output valves should
be fitted first observing the numbers 1,2,3,4 on the
rear of the valve; this corresponds with the four
REAR
sockets from left to right viewed from the
front. This was the position the valves were tested
in.
Do not push or pull these valves by the
glass envelope
, this could cause the glass
envelope to become detached from the base,
damaging the valve. Be careful to note the correct
orientation of the central “Spigot” between the
pins otherwise damage could occur. (Damaged
valves are not covered by our warranty)
The small valves are normally numbered 5,6,7
again left to right (see P1 photo) and should be
gently pushed into place. The middle valve is
6SL7 and the outside pair are 6SN7. Some
Russian tubes may have different numbers, if so
go by the number written on the valve.
3 Connect to source units
, e.g. CD, Tuner,
Phono pre amp, MP3, AV etc via appropriate
phono sockets.
No “recording” or line output
facilities are provided. For this you could use our
“Passive” or “Passive R” remote control pre amp.
4 Connect to speakers
Make sure to get the
correct polarity of speaker cables. (See speaker
connections chapter). If ‘bi-wiring’ both ‘common’
should go to the black terminal, and both ‘positive’
(or red) should go to the red terminals. Most
speakers have a “spread” of impedance between
about 3 and 14 ohms. As ther
e is some “overlap”
between the 4 and 8 ohm outputs, you may wish
to try both to experiment which tonal balance you
prefer.
5 Connect to mains
supply using supplied IEC
mains lead to 230/240v supply (or 110/120 if
modified see label).
If for some reason the
welded plug must be removed, please remove
fuse and dispose of immediately.
(As they can
be a danger to children if plugged in). The
replacement plug should be wired in the following
way Brown to Live terminal, Blue to Neutral
terminal and Green/Yellow to Earth terminal.
6 SWITCH ON!
The LED mains indicator should
light up. Leave for at least 60 seconds for the
valves to warm up. The amplifier should now be
working. All valves should have a visible orange
glow from the cathode heaters. With the volume
control set to minimum (fully anti-clockwise) there
should be no sound coming from the speakers
except a barely discernable gentle hum. If there
are any unpleasant sounds coming from the
speakers, switch off and refer to the ‘Trouble
Shooting’ section or contact Icon Audio. If the
optional “HT delay” is fitted, this will automatically
switch on after about 60 seconds.
7 Your unit should now be functioning
. If not
check
wiring
again
and/Use
selector/tape
monitor/volume to choose source program and
suitable listening volume. Do not operate at a high
volume for the first five minutes to allow the valves
to warm up properly.
Please note all these things are normal for
valve amplifiers:
A, Valves can get very hot, BEWARE!
B, The transformer cover will get quite warm
C, The amplifier may
have a “new” smell for a few
weeks.
D, M
obile phone ‘breakthrough’ is normal.
E, Valves may make a ‘tinkling’ sound when
warming up and cooling down.
F, One channel may come on before the other at
switch on.
G,
There may be a ‘click’ when switching off.
8 Health and Safety
. The valves when operating
have high surface temperatures. Keep out of
reach of children and pets. The use of the
supplied guard is recommended in these
circumstances. Always unplug when making
adjustments.
Like all amplifiers there are
potentially lethal high voltages inside (over
400v DC), which when switched off can take
twenty minutes to discharge!
Do not remove
bottom panel unless you are a competent
engineer. There are no user serviceable parts
inside.
Like
other
household
electrical
appliances do not leave unattended whilst
switched on.
Do not adjust the bias pre set
without reference to the manual. Incorrect
adjustment could cause the valves to overheat,
with resulting
in damage to valves and
amplifier.
To maintain the best performance of the
amplifier you should check the bias of the
output valves from time to time (say once a
year). Full details will be found in section 6.
In this manual we have attempted to give you all
the information to enable you to get the best out of
this amplifier, without being overly long or too
technical. However we are always keen for
feedback on errors or omissions on the
information within!
