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 KT88s should be fitted
first observing the numbers 1,2,3,4 on the rear of
the valve; this corresponds with the four sockets
from left to right viewed from the front. This is
essential as each valve is ‘set up’ in this position.
Do not push or pull the KTs by the glass
envelope
, this could cause the glass envelope to
become detached from the base, damaging the
valve. The small valves may be gently pushed into
place (12AT7= ECC81, outside pair, 12AX7=
ECC83, inside pair). It is normal for them to feel a
little loose.
3 Connect to source units
, e.g. CD, Tuner,
Tape, Phono pre amp (if used) etc via appropriate
phono sockets.
4 Connect to speakers
(4 to 16 ohms) Don’t
forget 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 8 ohm
terminals.
5 Connect to mains
supply using supplied IEC
mains lead to 240v supply.
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 blue mains indicator should
light up and unit will take approximately 40
seconds to start 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 your unit is fitted with the HT delay timer,
operation will begin after the unit switches the HT
on (approx 40-70 secs), your may hear very low
distorted sound from the speakers during the
warm up time. This is because there is virtually no
HT to operate the
amplifier. We suggest you
reduce the volume until the HT cuts in.
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.
Remote Control
The remote control can be found in the bottom of
the box. It controls the volume by means of a
motorised volume pot. Pressing “mute” will reduce
the volume to zero. Make sure that you point the
control directly at the sensor on the amplifier front
panel. If you are having difficulty operating the
handset from an oblique angle, try pointing at
something reflective, e.g. the opposite wall, or
place a small reflective item at a suitable angle in
front of the amplifier. A small dot of white paint or
“Tippex” will enable the little “dimple” on the
volume control to be more visible.
Please note that upon “switch-on” the remote
control unit automatically re-set s to a low volume.
When the blue LED gets low you should replace
the batteries with 2x AAA cells.
Please note all these things are normal for
valve amplifiers:
A, Valves can get very hot, BEWARE!
B, The mains transformer will get quite warm
C, The amplifier will smell slightly at first.
D, Mobile 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, The volume control may sometimes appear to
sound ‘Scratchy’, this is not a fault!
H, There may be a ‘click’ when switching off.
8, Do not switch between “Ultra” and “Triode”
without first switching off. This could cause
irreparable damage to the transformers which
would not be covered under warranty.
9 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
500v DC), which when switched off can take
several 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 KT88 grid bias
pre sets without reference to the manual. Incorrect
adjustment could cause the valves to overheat,
with resulting in damage to valves and amplifier.
10 Important that you check the check the bias
reading once or twice a year. This will ensure
peak performance and maintain valve life.
See section 7.
