The lightning ash with arrowhead symbol within an equilateral triangle is intended to
alert the user to the presence of uninsulated dangerous voltages within the enclosure
that may be of sucient magnitude to constitute a risk of electrical shock to the user.
Please read this User Manual thoroughly before attempting to install, congure, or
operate the BASX A-100. After successful installation and conguration of the A-100, be
sure to retain this manual in a safe place for future reference.
Safety is a key component to a long lasting and trouble free installation. Please read and
follow all instructions and heed all warnings on the BASX A-100 and in this manual. The
vast majority of the subsequent safety precautions are common sense. If you are not
comfortable with the installation of audio/video entertainment equipment, you should
seek the services of a qualied installation professional or call us for help.
WARNING: To prevent the risk of re or electric shock, do not use the BASX A-100 near
water or in wet locations and do not expose it to rain or moisture. Doing so may result
!
in damage to the A-100 and the risk of electric shock, which may result in bodily injury
or death.
WARNING: To reduce the risk of electric shock, do not remove the cover from the
BASX A-100. There are no user-serviceable parts inside the A-100. Refer all service to
qualied service personnel.
To reduce the risk of electrical damage, verify that no short circuits are present between
terminals and/or speaker wires before applying power.
Do not install the BASX A-100 near any heat sources such as radiators or heating vents.
Avoid installing the A-100 directly above other heat-producing equipment unless
sucient ventilation or forced-air cooling is provided.
Do not install the BASX A-100 in locations without proper ventilation. The A-100 should
not be operated on a bed, sofa, rug, or similar surface that may block vents. The A-100
should not be installed in an enclosed location such as a bookcase, cabinet, or closed
equipment rack unless sucient forced-air ventilation is provided.
Connect the BASX A-100 only to power sources of the correct voltage (as shown in this
manual and on the A-100). Ensure that the Input Voltage selector switch on the rear of the
A-100 is set to the appropriate voltage.
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be
especially careful where the power cable enters the power outlet and A-100 unit.
Only connect the BASX A-100 to an electrical outlet or extension cord of appropriate type and
rating. DO NOT defeat the safety purpose of a grounding or three-pronged plug by removing
ground pins or using unsafe adapters. If you replace the A-100 power cord, only use one of
similar type and equal or greater current rating.
The power cable for the A-100 should be unplugged from the outlet during severe electrical
storms, or when unused for a long period of time.
The BASX A-100 should only be cleaned as directed in the User Manual. Avoid spraying liquids
directly onto the A-100 and NEVER spray liquids into the vents. Care should be taken so that
small objects do not fall into the inside of the A-100.
You should seek service for your BASX A-100 by qualied service personnel if any of the
following occur:
!
1. The power-supply cord or the plug has been damaged
2. Objects or liquid have fallen or spilled into the vents
3. The A-100 has been exposed to rain
4. The A-100 exhibits a marked change in performance
5. The A-100 has been dropped or its enclosure or chassis is damaged.
CAUTION
CAUTION: TO REDUCE THE RISK
OF ELECTRICAL SHOCK, DO
NOT REMOVE COVER. NO USER
SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.

BASX A-100
Introduction
Thank you for purchasing the new Emotiva BASX A-100 Stereo Flex Amplier.
Our BASX product line is dedicated to the philosophy that high-quality products that deliver true
audiophile sound quality don’t need to be expensive to buy or complicated to congure and
enjoy. All of our BASX ampliers give you great sound quality, excellent technical performance,
and outstanding value.
The BASX A-100 incorporates a compact footprint and “classic audiophile architecture”, centered
around a heavy-duty linear power supply and class A/B output stage. It will deliver enough
audiophile quality sound to drive most speakers to satisfying listening level. The BASX A-100
delivers 50 watts per-channel into 8 ohms and 80 watts per-channel into 4 ohms, and can be
controlled manually or congured to respond to a trigger input or the presence of an audio signal.
The BASX A-100 is also a true integrated amplier, and includes a front panel Volume control.
Another special feature, which serious headphone acionados will appreciate, is a headphone
output which is derived from the main amplier outputs via a set of high quality, low noise, series
resistors. This enables the A-100 to oer the same listening experience that headphone lovers
prize in high-end vintage equipment, only with the vastly improved performance made possible
by the modern circuitry in the A-100. Another very unusual feature, which will prove invaluable
to the owners of low-eciency planar headphones, is the ability to bypass the series resistors
entirely, and so connect the headphone output directly to the output of the main ampliers.
This allows the A-100 to optimally drive very low eciency headphones without the need for
expensive and complicated adapters and adapter cables.
As with all our BASX ampliers, the A-100 includes our intelligent protection circuitry, which
protects the unit and your speakers from most common fault conditions, and we’ve paid special
attention to important details like heavy-duty audiophile grade binding posts and carefully laid
out signal paths.
If you need a superb sounding amplier, with excellent build quality, and a compact footprint,
or if you’ve been looking for a superb quality “speaker amplier” to drive your dicult to drive
headphones, then the BASX A-100 is for you.
Check it out; you’ll be glad you did.
Happy listening!

BASX A-100
Features
The BASX A-100 is a great sounding, compact, and very exible, stereo amplier. The A-100
includes features that make it a great choice in a wide variety of situations; from driving a small
music system in a home or business, to providing audio for a second zone in a larger home
theater installation, or whole house music system. The A-100 also includes a great sounding
headphone output, which combines the sonic signature of high-end vintage equipment with the
superb performance of modern circuitry, and which oers the ability to drive low-eciency planar
headphones without the need for adapters and custom cables.
• Best-in-class design and sound quality. The A-100 shares the same superior design and
high-quality parts as our bigger ampliers, so it performs “like the big boys” and sounds far
better than most amps in its price and power class.
• 50 watts per-channel @ 8 ohms (80 watts per-channel @ 4 ohms) of superb sounding
audio - sucient to drive most speakers to satisfying listening levels.
• Classic style headphone output - driven from the main amplier outputs via a set of high-
quality series resistors; duplicates the sound signature of the highly-prizes headphone
outputs on high-end vintage equipment.
• Direct output option for low-eciency planar headphones. This option allows you to
route the main speaker outputs of the A-100 directly to the headphone jack to drive
low-eciency planar headphones properly - without special cables or adapters.
• Flexible power switching. The A-100 can be congured to switch on when a trigger is
received and when it senses audio signal on its inputs. The Trigger Output can be used to pass
trigger signals to other components.
• Front panel volume control. With its convenient analog front panel volume control, the
A-100 can accept inputs from both variable and xed audio sources.
• Heavy duty power supply with massive toroidal transformer provides plenty of
continuous power to drive even low eciency speakers, and enough dynamic power to
eortlessly reproduce musical peaks without strain or distortion.
• Compact size makes it easy to nd a location for your BASX A-100.
• Loop output. The A-100 oers a loop output to facilitate chaining additional ampliers or
other devices.
• Full sized ve-way binding posts make it easy to attach thick wires, lugs, or banana plugs.
• Illuminated Volume knob. The A-100’s volume knob is surrounded by an illuminated ring,
which indicates both Power and Fault status.
• User selectable AC line voltage; 115 VAC or 230 VAC.
