1 Unpack unit carefully. Make sure that it is in good
condition. It is important that you keep packaging for
warranty/service return.
2 Fit the valves if necessary. The two bigger valves
have a "keyway" on their spigot. It is essential that you
observe this when fitting. If already fitted check that
they are seated properly. (see also valve replacement)
3 You may connect directly to your source unit
(e.g. CD player) or use the "Record Out" of your (pre)
amplifier. Or connect by Bluetooth. See section.
"Loop Through" Facility (Not fitted to Bluetooth).
This enables you to connect the HP8 between a pre-
amplifier and power amplifier for example, or it may be
used as a "record out". The "Loop out" does not
require the HP8 to be switched on.
4 Connect to mains supply using the attached mains
lead to 230/240v supply. Outside the UK you may
need to change plug or cable, the welded plug must be
removed and replaced with a suitable type.
remove fuse and dispose of carefully away from children. The
replacement plug should be wired in the following way Brown to Live
terminal, Blue to Neutral terminal and Green/Yellow to Earth
terminal.
5 Connect your headphones and SWITCH ON!
The red 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 your headphones except a barely
discernable hum.
5a, Headphone Impedance
The right hand knob marked L M and H refer to the
matching impedance of your headphones and are
banded as follows:
Low
8-40 Ohms
Med
30-300
High
250-1000
Where there is overlap choose whichever sound you
prefer.
6 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.
The best sound quality will be when the unit has
warmed up for at least 20 mins.
7 Health and Safety. The valves when operating have
moderately high surface temperatures. Keep out of
reach of children and pets.
Under no circumstances operate with valves
removed!
Connecting inputs & outputs
Many problems with hi fi equipment involve connecting
leads which are usually either 'Bad, or Wrong
connection'. So it's worth making sure that you have
good connections and that your leads are the right way
round.
Inputs
The amplifier will work with any standard piece of hi fi
e.g. CD, Tuner, Tape Deck, Mini Disc, TV, Video
Recorder, DVD etc.

Bluetooth Operation
(Where fitted)
1. Attach antenna to rear of amplifier unit.
2. Switch on and connect headphones. To start
Bluetooth pairing operation switch the
rear selector to "Bluetooth".
3. Now open the Bluetooth menu of
your phone (or other device) and
search for "iconaudio" in the list, then
"pair" with the HP8. If connection
does not work you may have to
switch off the HP8 and try gain.
Follow
the
instructions
Bluetooth source unit.
4. Select and play music as required.
5. Note the maximum range may be limited by walls,
furniture and other interference sources.
6. In most cases once "Paired" re-connection will be
automatic. Bluetooth is activated at switch-on. To re-
set the Bluetooth circuit switch off for a few seconds.
Low level Interference:
Under some circumstances Low level noise may be experienced due
to interference from other sources and may even break through
when Bluetooth is not in use. This not a fault. If you do not need to
use the Bluetooth board it may be disconnected by unplugging the
small two wire lead from the internal board. Remove power lead
before opening.
General points
•
Mobile phone 'breakthrough' may happen if your
phone is too close to the HP8.
•
A switch-off 'click' through the headphones is
normal.
•
Valves get hot beware!
•
Storage in damp conditions could damage
transformers.
Connecting Leads
Use good quality connecting leads, which are no
longer than they need to be.
Leaving the HP8 switched on
Whilst the amplifier will sound at its best when it is
properly warmed up after about 10 minutes, there is no
advantage leaving it switched on continuously when it
is not in use. It is using electricity and using up valve
life. Conversely the valves and other components are
stressed more at switch on; therefore do not switch on
and off unnecessarily. Although the amplifier should
sound good within a few minutes, like most hi fi
units it will take a couple of months of regular use
before it is fully 'run in'.
Cabinet Care
To remove dust from the cabinet and valves we
suggest gentle brushing with a soft paintbrush and a
duster. Finger marks can usually be removed with a
damp
cloth.
Always
disconnected.
