Safety Instructions
They’re Important, So Please Read Carefully!
Please DO…
Keep these instructions in a safe place for future reference – you may need them
The SOLIS works best on a clean, dry and flat surface. Try it, you’ll see.
The SOLIS needs room to breathe, so made sure it’s new home has adequate
ventilation. Don’t put it on beds, sofas, rugs, enclosed bookcases / cabinets or
anywhere else where its ventilation maybe obstructed and it can overheat.
Made sure that your SOLIS is connected to the correct power supply as indicated
on the unit.
Unplug your SOLIS when it’s not in use for a long period (days not hours)
Always make sure power cables are placed safely and not obstructing a walkway.
If you move your SOLIS from a cool to a warm place, condensation may form on
the surface of the vacuum tube. It’s nothing to worry about, but allow 1 hour
before you switch it on again. This will avoid leakage or a blow out of the vacuum
tube due to too much sudden heat.
You really should get your SOLIS serviced by an authorized service engineer if:
1. The power supply or cord is damaged
2. It drops or is struck by a falling object
3. It’s exposed to rain or moisture
4. Liquid is split on it
5. It’s not operating normally or shows a sudden change in performance
Please DON’T…
Don’t put your SOLIS anywhere near water – it hates it. So avoid placing it near
bathtubs, sinks, washing machines, swimming pools, saunas, Jacuzzis, kettles,
precariously balanced pints of beers etc.
Exposed it direct sunlight or to extremes of temperatures or humidity.
Don’t leave it near direct heat sources such as radiators, stoves, gas fires, naked
flames or candles.
Never drop the unit. It’s delicate, so don’t apply excessive force to the controls or
place heavy objects on top of it either.
Don’t let too much dust gather on your SOLIS – give it a regular wipe with a soft
dry cloth. If necessary, use a slightly damp cloth but DO NOT use solvents.
The SOLIS has valves, and they can get hot. Don’t touch the tubes and keep away
from babies and children.
Don’t try to remove the cover or the back – there are no user-serviceable parts,
and you don’t want to risk an electric shock.
NOTE: Any unauthorized changes or modifications to this equipment render the
manufacturer’s warranty null and void.
Amplifier Connections
Before connecting anything to or from your SOLIS, switch off the power to the
SOLIS and to components you want to connect.
Make sure that all connections between the SOLIS and other components are
made correctly, so L(left) goes to L, R(right) goes to R, + to + and – to -> Don’t
forget to refer to owner’s manual of each component that you want to connect.
Always turn OFF the power switches when you’re connecting or disconnecting
from the mains.
Disconnect the power supply from the mains if you’re not planning to use your
SOLIS for a while eg holidays.
Any speakers you connect should have an impedance of 4 ~ 8 ohms, if it’s not
written on the back of the speaker, check with the distributor.
Speaker Connections
Connect to your speakers using high quality, bare (stripped) speaker wire. If your
speaker wires are not connected properly you may hear no sound at all, or if the
wires are mixed up, it will sound weird with a disturbing loss of bass.
When using bare speaker wires, fit at least 1.6mm of insulation inside the speaker
terminals so that there’s no bare wire showing.
Made sure the wire holders are firmly screwed in to stop the wires from
becoming loose. If wires touch, the speakers or the unit could be damaged. That’s
bad.
The Front
Power Switch
Press to ON for power – the indicator will light up while the power is on. Later on,
try pressing it off to give it a rest.
Source
For switching between Bluetooth and auxiliary in source from different sound
inputs like smartphone device, tablet device, CD player etc.
Volume Control
Full control – you can turn it up or you can turn it down
NOTE: Before you switch on, set the volume control to the lowest setting to avoid
damage to the speakers. Just in case you don’t, the speaker protection circuit will
mute the volume for a few seconds after the power is switched on.

VOLUME KNOB
The Back
5 minute rule!
Your SOLIS should only be re-started 5 minutes after switching off to
avoid damaging the tubes.
Problem Diagnosis
SYMPTONS
DIAGNOSIS
CURE
Won’t turn on when the
POWER switch is pressed
Power adaptor isn’t
connected properly; main
supply is off
Make sure the power
cable is firmly plugged in
and mains is switched on
No sound
The volume control is
turned all the way to the
left.
The connection wires are
not connected securely to
the INPUT terminals.
Speakers are not
connected properly
Turn the control to the
right to crank up the
volume.
Make sure the cords are
fully inserted at both
ends.
Check that the speaker
cables are connected
correctly
No sound from left or
right speaker
One or both speakers are
not properly connected.
SOLIS input isn’t properly
connected
Check both speaker cables
and ensure they’re
connected securely
Check the connections
between your source and
amplifier are correctly
and firmly connected
The acoustic image is
unstable (sounds
unnatural or weirdly bass
light)
The positive and negative
polarities of the unit and
speakers aren’t matched
Remove the speaker
cables and re-connect
them correctly
Crackling sound from
speakers
Bad Connection
A problem with your
audio source
Check docking station
connection (or the 3.5mm
cable connection if using).
Make sure it’s using line
out, audio out or
headphone out from your
source, “NOT speaker
out”.
Test the 3.5mm cable with
another audio source eg
CD player, MP3 player
Sound is distorted
Volume level on SOLIS is
too high
Sound source is distorted
Turn it down a bit, WAV
and MIDI files are often
poor quality and
distortion sounds worse
through a quality system –
try a different audio
source eg CD
Radio Interference
You may be too close to a
radio tower
Try moving the speakers
to different positions
