Hallo i'm new of the forum.... Before to start i want said a big hallo to all forum..... I type from italy, and i want make an answare... I have an ami h 200 selection, that works fine... I have but an amivox s-81 external speaker, and i want connect with out damage the amplifier.... How must do?. I don''t understand where i must wire the cable of external speaker . The speaker can work in 8 ohm mode or 500 mode.... What are the right point to connect the speaker on the amplifier?

Hello!
Normally on the Amplyfier is a Conncting Schema for extern Speakers.
You can see on the Picture the Possibelytis to do it.

This's photos of my amplifier, and ther socket..... I must connect 4 and 5 pin to amplifier... but where???

For the scheme i must connect the speaker on the 6 and 7 or 5 and 6 pin..... but on the socket wire are missing...... why???

Hello!
You can connect your extern Speaker directly on the Amplyfier in the Number 8 and 9 for 500 Ohms for 3,5 Watts
or on 5 and 8 for 1 Watt for 500 Ohms.
Also you can connect on 6 an 7 for 7 Watts for 8 Ohms, or on 5 and 6 for 2,5 Watts.
I dont know the Connecting Board form your Picture one.

Hello oldultras

You'll be able to connect the speakers in different ways. If you have a very long cable to the speaker, it is better to use the 500 ohm matching. In this way, line losses are avoided. In this case, you use the terminals 1 and 2 on the speaker. Terminals 3 and 4 must be connected by using the link. On the amplifier you can use terminals 5 to 9. According to the chart the terminals 5 and 8 gives 1 watt for the speaker, the connecting to 8 and 9 equals 3.5 watts.

For short distance to the speaker, the low impedance connection is preferable. In this case the terminals 4 and 5 are to be used on the speaker. On the amplifier, the terminals 5 and 6 (for 2.5 watt) or 6 and 7 (for 7 Watt) are to be used, according to the chart.

The internal speakers are currently connected to the terminals 6 and 8. You can adjust the volume balance between internal and external speakers when you connect the internal speaker to other terminals (corresponding to the left-hand list). Note the statement: "total watts for all speakers (phono and / or remote) must not exceed 22 watts".

I have connect the external speaker at pin 5 and 6 at 2,5 watt.... I have read the DISCLAIMER to not passed the 22 watt .... But the curiosity to put the external speaker at 7 watt is very high... I'm afraid to broken amplifier (16+7=23 watt).

Now works very great..... Thank you to all.... If someone wants the internal connection of amivox s81, i can pass the photos....

Instead I wanted to tell the person on the forum, who sold me the external speaker, saying it was perfectly ashamed only ..... Great crook ..... The webmaster is aware ....


Thanks you again to the forum ....

Hello oldultras

There is no risk that the amplifier will be damaged by an over-load of 1 watt. At worst, the distortion may increase slightly at maximum volume.

Ok i prove and refer to the forum... Thank you again...

If some body need i have the step by step guide (photos) to put inside the speaker the animation....

Hi odultras

Yes I need the Step by Step guide ,i send you a private Message.
Thanks and Regards

No problem i post here the photos .... Or open a new topic....

Step by step guide.....

Aluminum core.............

Masonite insulative rings.........

Relief areas for wires........

Bonded together..............two views.

Test lighting... blinking bulbs.............

Assembled to front casting.... bulbs in front of speaker, behind grille cloth...

Mohair noise baffle installed................

Rubber seal partially installed.............

Bulbs are like this type..... works on 115 V

Here are links to the bulbs and the bases. Modify the base by removing the loop where the wires go through. Extended tab should stay in place and be part of what bonds the base to the 'fingers' that reach out of the rings made of aluminum and masonite. Also, use a wire tye on each one.
