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
(nearest the transformers) from left to right viewed
from the front. This is essential as each valve is
‘set up’ in this position. The smaller valves may be
gently pushed into place. The outside pair = 6SN7
(numbered 5 and 8), the inside pair = 6SL7
(numbered 6 and 7).
Do not push or pull the
valves by the glass envelope
, this could cause
the glass envelope to become detached from the
base, damaging the valve.
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 Before switching on make sure that the
“standby switch” is in the “up” position.
SWITCH ON!
The blue mains indicator should
light up. Leave for at least 60 seconds to for the
valves to warm up, and then push the “standby”
switch into the “down” position. 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 your unit is fitted with the optional HT delay
circuit, only use the “Standby” when switching
from “Triode” to “Ultralinear” operation or when
the amplifier will not be used for a while.
6a Integrated/Power Amplifier Switch
Located on the rear, this switch is normally “UP”
for integrated operation (high sensitivity). If use
with a pre-amplifier is required, the switch should
be “DOWN” in the low sensitivity position. We
would recommend use of the tape input with the
volume on “FULL” or set as required and volume
adjusted from your preamplifier (although if you’re
your pre-amplifier is not remote control, you could
“fix” the volume the pre-amp, and make use of the
Stereo 60 remote control).
7 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.
8 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-sets to a low volume.
When the blue LED gets low you should replace
the batteries with 2 x 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.
9 Do not switch between “Ultra” and “Triode”
without first switching off. This could cause
