WARNING: THIS EQUIPMENT MUST BE EARTHED
(CLASS I APPLIANCE)
Risk of re: Do not expose to rain or moisture.
No user serviceable parts inside – refer servicing to qualied personnel.
Only to be used at altitude below 2000 metres.
Only to be used in non-tropical climate regions.
For indoor use only.
Do not use this amplier if the electrical power cable is frayed or broken.
No naked ame sources such as lit candles should be placed on the equipment.
This device must be powered exclusively by earth connected mains sockets in
electrical networks compliant with IEC 364 or similar.
This unit has been engineered and manufactured to ensure your personal safety.
IMPROPER USE CAN RESULT IN POTENTIAL ELECTRICAL SHOCK OR
FIRE HAZARD
In order not to defeat the safeguards incorporated into this product, observe the
following basic rules for its installation, use and service. Please read “Important
Safeguards” listed below carefully before use.
1.1 Important safety instru tions
1.2 Important safeguards
1.3 WEEE Dire tive
Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this equipment near water.
Disconnect the AC mains source before attempting to clean any part of the
amplier.
Clean with a damp cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s
instructions.
Do not install near any heat sources such as radiators, stoves, or other apparatus
that produce heat.
Protect the power cord from being walked on or pinched particularly at power
outlets and the point where they exit from the apparatus.
Only use attachments/accessories specied by the manufacturer.
Use only with the trolley, stand, tripod, bracket, or table specied by the
manufacturer, or sold with the apparatus. When a trolley is used, use caution when
moving the trolley/apparatus combination to avoid injury.
Unplug this apparatus during lightning storms or when unused for long periods of
time.
Refer all servicing to qualied service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
The apparatus shall be connected to a MAINS socket outlet with a protective
earthing connection.
THE MANUFACTURER CANNOT BE HELD RESPONSIBLE FOR DAMAGES
CAUSED TO PERSONS, THINGS OR DATA DUE TO AN IMPROPER OR
MISSING GROUND CONNECTION.
The Waste Electrical and Electronic Equipment Directive (WEEE Directive) aims
to minimise the impact of electrical and electronic goods on the environment.
Funktion-One Research Ltd. comply with the Directive 2012/19/EU.
Funktion-One products are designed for longevity and repairability, we hope they
provide many decades of enjoyment and useful operation. In the unlikely event that
you need to dispose of your Funktion-One product, all of our products are marked
with the WEEE symbol; this indicates that this product must NOT be disposed
with other waste. Instead it is the user’s responsibility to dispose of their unwanted
Funktion-One electrical and electronic equipment by returning it to Funktion-One
Research Ltd. for recycling and reprocessing.
For more information about where you can send your waste equipment for
recycling, please contact Funktion-One Research Ltd. or your local distributor.
The SB8A/SB10A contains a universal power factor corrected (PFC) switched-
mode power supply (SMPS) which operates on a voltage range of 100-240V AC,
50-60Hz.
The SB8A/SB10A contains hazardous internal voltages. Do not open the amplier
enclosure – risk of electric shock.
No user serviceable parts inside. Refer servicing to qualied personnel.
The SB8A/SB10A is a Class I appliance and MUST be connected with a three-
wire cable to a mains outlet with a safety earth connection.
THE EARTH WIRE SHOULD NOT BE DISCONNECTED UNDER ANY
CIRCUMSTANCE.
IEC C13 mains cables are readily available worldwide.
For reference, the mains wiring in EU countries is:
Earth: Green and Yellow
Neutral: Blue
Live: Brown
The mains inlet contains a user-replaceable fuse.
For continued protection against re, only replace the fuse with the same type and
rating: T3.15AL 250V (5x20mm glass)
1.5 Ele tri al onsiderations
1.6 Me hani al & thermal
NEVER under any circumstance replace the fuse with a higher rating. Risk of re
and damage to the equipment.
Repeated fuse blowing indicates a fault and the amplier must be returned to
Funktion-One for service.
ENSURE THERE IS ADEQUATE VENTILATION
The amplier enclosure is convection cooled therefore care must be taken to
ensure that sufcient volumes of air can ow across and through the amplier.
This is usually accomplished by ensuring vents are not blocked and at least
100mm (4’’) of free space from the rear panel of the amplier module, and 150mm
(6”) above the cabinet.
If airow is impeded, the amplier will overheat and enter thermal protect mode
(fault LED solid red).

SAFETY AND REGULATIONS
1.7 Safety symbols
The triangle with the lightning bolt is used to alert the
user to risk of electric shock.
The triangle with the exclamation point is used to alert
the user to important operating or maintenance
instructions,
For United States of America
Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wide blade or the third
prong are provided for your safety. If the provided plug does not t into your
outlet, consult an electrician for replacement of the obsolete outlet.
1.6 Volume warning
The SB8A/SB10A is capable of producing high sound levels that can damage
your hearing over time. Care should be taken to manage your noise exposure
levels.
4Ωloads on the satellite outputs will signicantly increase the thermal dissipation,
and forced air cooling may be required to sustain full output in high ambient
temperatures.
The amplier is designed to be permanently xed inside the loudspeaker cabinet
and should not be operated outside of the cabinet.

SB 8A /SB10A U SER GUIDE
11 12
This section explains how to choose the correct cable type for connecting your audio source with the SB8A/
SB10A system.
Audio connections come in two main types: balanced and unbalanced. Professional equipment is typically
balanced and domestic equipment is typically unbalanced.
Balanced connections have three conductors for each audio signal and have greater resistance to
electromagnetic interference, ground loops (hum/buzz) and noise. Unbalanced connections have two
conductors for each audio signal providing adequate performance for short cable runs.
The SB8A/SB10A’s balanced XLR input should be used for connecting equipment with balanced XLR or jack
outputs capable of high output levels such as mixing desks and DJ mixers.
The unbalanced ¼” jack input on the A1 amplier should be used for connecting equipment such as laptop
and phone outputs, unbalanced hi preamps and other low level sources.

The SB8A/SB10A has Left and Right outputs for powering passive mid-high ‘satellite’ loudspeakers in stereo.
The outputs can supply up to 150W into 4Ωand are actively high passed at 140-150Hz.
Both the SB8A and SB10A can power the F5, F55, F81.2 or F101.2 but for a balanced sound we
recommend the following systems:
SB8A – 2 x F5
SB10A – 2 x F81.2
6.5 Output Conne tions
6.6 Re ommended loudspeakers
If you are permanently installing your SB8A/SB10A system in a home or venue (i.e. not using the provided
satellite loudspeaker cables) there are additional safety and compliance considerations for loudspeaker
To comply with IEC60092, IEC60332.1, IEC60332.3C, IEC60754.1, IEC60754.2 and IEC60134.2
loudspeaker cable installations in public buildings, clubs etc. must use Low Smoke Zero Halogen (LSZH)
cable.
Please reference the table below when choosing your cable length and conductor size

The maximum power that can be supplied from the outputs is 150W into 4Ω. This is equivalent to:
4x F5 in parallel per channel or 2x F81.2 in parallel per channel.

The SB8A/SB10A’s outputs use the robust and safe Neutrik Speakon connector.
The NL4 is a 4-pin connector, but only two pins are in use. Both NL4 and NL2 cable connectors will mate
with the NL4 socket on the SB8A/SB10A.

No application of force is required at any stage of connection or disconnection!
The Speakon is a professional connector and is used as follows;
1. Insert the Speakon plug lining up the wider notch at the top of the socket.
2. Rotate the plug clockwise until you hear a ‘click’ - the connection is locked.
To disconnect the Speakon:
1. Pull back and hold the latch with your thumb
2. Rotate the plug counter-clockwise as far as it will go
3. Pull the plug out of the socket
