"dangerous voltage" within the product's
enclosure that may be of sufficient
magnutide to constitute a risk of electric
shock to persons.
Warning:
To prevent electric shock, never open this
product.
No user-serviceable parts inside.
Leave all service to qualified service
personnel.
Safety Precautions
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance
1. Heed warnings : All warnings on the product and in the User’s
Guide must be adhered to.
2. Read all instructions before using this product, and keep the
instructions safe for later reference.
3. WARNING: To reduce the risk of fire or eletric shock, do not
expose this product to rain or moisture - Never use the product
immediately after moving it from a cold environment, which
may cause condensation.
4. The product must be positioned in such a way that there is
sufficient ventilation at all times.
5. Do not place the product near heat sources, such as radiators,
heaters or any other heat-emitting appliances.
6. Avoid placing in direct sunlight.
7. The product may only be attached to a mains supply that
corresponds to the marking on the product.
Do not defeat the safety purpose of a 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 safety reasons. If the provided mains plug does not fit into
your outlet, consult an electrician for replacement of the obsolete outlet.
8. If the product is not used for a longer period of time, or for
added protection during a lightning storm, disconnect the
mains lead from the wall outlet.
9. Pull on the mains plug - never the mains lead itself - when
disconnecting the plug from the wall outlet.
Ensure that the mains lead does not become stretched or
trapped/clamped, especially around the mains plug and the
point at which the lead is connected to the product.
10. Always follow the user instructions when making connections
to other appliances.
11. Take care not to drop objects or spill liquid through the
openings in the product.
12. The product should be serviced by qualified personnel if:
• The mains lead or plug is damaged.
• Objects are dropped or liquid is spilled into the product.
• The product has been exposed to rain.
• The product is not operating normally.
•The product has been dropped and/or the cabinet is
damaged.
13. Please note that this product - either alone or combined with
an amplifier, loudspeakers or headphones - can cause damage to hearing.
Never play at high volume for longer periods and never play
so loud that it feels uncomfortable.
Warning! It can be particularly difficult to estimate sound pressure in the deep bass area, which is why extra attention must
be paid in order to avoid harmful sound pressures.
Always contact your doctor if you experience loss of hearing
and/or ringing in the ears.
14. Warning : Power-supply cords should be routed so that they
are not likely to be walked on or pinched by items placed upon
or against them, paying particular attention to cords at plugs,
and the point at which they exit from the product.

Introduction
Congratulations on your purchase of your new Jamo Multi-Purpose Amplifier (MPA-101). It is
backed by state-of-the-art engineering and manufacturing techniques to bring you the best
quality craftsmanship and reliable performance.
The MPA-101 is specifically designed for home theatre applications. Because of its ample power
and two-channel capacity (stereo), it can fit into virtually any surround application. Narrow width
chassis is designed for convenient shelf or system rack mounting in the space of the one stereo
component.
It allows you to use one amplifier as left and right stereo front speakers, second amplifier use as
left and right rear (surround) speakers and third amplifier use for centre channel.
Bridge mode capability allows the use of the two channels connected together to form one
high power amplifier channel, providing 100 watts into 8 Ohm.
The MPA-101 is also a subwoofer amplifier with adjustable electronic crossover. With switch in
OFF position it becomes full range amplifier.
The power rating for the Jamo MPA-101 power amplifier are obtained using fixed value test
load impedances and high intensity sine wave test tones. However, the actual impedance of the
loudspeaker will vary with frequency, deviating somewhat from the loudspeaker manufacturer’s
nominal impedance rating.
This Jamo amplifier has been specially designed to drive any modern loudspeaker system with
a rated impedance of 4 Ohms or higher.
Features
1. Power output, rated at 2x50 Watts (stereo) into 4 Ohm
2. High power output (bridged mode), rated at 100 Watts into 8 Ohm
3. Subwoofer amplifier, adjustable crossover frequency 50 Hz – 150 Hz
4. Full range amplifier
5. Extensive heat sinks for reliable operation and long life of the amplifier
6. High current discrete power transistors in the output stage for the best possible performance
7. Automatic power turn “ON”
8. Level control
9. Gold plated RCA input and output jacks
10. Heavy duty push button binding posts
11. Overload protection
