1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
12. Use only with the cart, stand, tripod, bracket, or table specifi ed by the manufacturer, or sold with the apparatus. When a cart is used use caution when moving the cart / apparatus combination to avoid injury from tip-over.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings.Install in accordance with the manufacturer's instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifi ers) that produce heat.
9. 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 is provided for your safety. If the provided plug does not into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments / accessories specifi ed by the manufacturer.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
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.
15. WARNING: To reduce the risk of electric shock, this apparatus should not be exposed to rain or moisture and objects “ lled with iquids, such as vases, should not be placed on this apparatus.
16. To completely disconnect this equipment from the mains, disconnect the power supply cord plug from the receptacle.
17. The mains plug of the power supply cord shall remain readily operable.

Introduction
Congratulations on your purchase of your new Jamo Multi-P urpose Amplifi er (MPA-201). It is backed by state-of-the-art engineering and manufacturing techniques to bring you the best quality craftsmanship and reliable performance.
The MP A-201 is specifi cally designed for home theatre applications. Because of its ample power and tw o-channel capacit y (stereo), it can fi t into virtually any surround application. Narrow width chassis is designed for conv enient shelf or syst em rack mounting in the space of the one stereo component.
It allows you to use one amplifier as lef t and right stereo front speakers, sec ond amplifier use as left and right rear (surr ound) speak ers and thir d amplifi er use for centre channel.
Bridge mode capability allows the use of the two channels connected together to form one high pow er amplifi er channel, pro viding 200 watts int o 8 Ohm.
The MPA-201 is also a subwoof er amplifi er with adjustable elec tronic crossover. With switch in
OFF position it becomes full r ange amplifi er .
The power rating for the Jamo MPA-201 pow er amplifi er are obtained using fi xed v alue test load impedances and high intensity sine wave t est tones . However, the ac tual impedanc e of the loudspeaker will vary with frequency, deviating somewhat from the loudspeaker manufacturer's nominal impedance rating.
T his Jamo amplifi er has been specially designed t o drive any modern loudspeaker system with a rat ed impedance of 4 Ohms or higher .

Connection
The Jamo MPA-201 is equipped with gold-plated push button binding posts which will accept very heavy stripped wire. Ask your local Jamo dealer for advice on the choice of cable.
Connect the loudspeakers to your Jamo MPA-201 as follows:
1. Turn of the MPA-201
2. Carefully remove approx. 3/8" /10 mm of the insulating material
- beware not to damage the conductors!
3. Twist the conductor ends
4. Push the binding posts so the conductors can easily fit into the holes
8
Note: Make sure that the stripped + and - wires do not touch each other, as a short-circuit could damage the
Jamo MPA-201's output section.
Always make sure that:
Your loudspeakers are in correct phase;
The loudspeaker 's + terminal is connected to the Jamo MPA-201's + terminal.
T he loudspeaker's - t erminal is connected to the Jamo MPA-201's - terminal.
Usually , the loudspeaker cable is marked on one wir e which is normally used to connect the + terminals to ensure correct phase.
