Com terminal on MC2205

"W-1 Phase" error, when running the YPAO, means that one or more of the speakers in your home theater set up is out of phase. This happens when the + and - wires are not consistent throughout all of the speaker connections (red and black terminals). Make sure your red/copper color wire is connected to the "red" speaker terminals , and the silver color wire is connected to the "black" speaker terminals. This error can also happen even if all of the speaker cables are connected correctly but the acoustics of the room are creating the out of phase sound the microphone is picking-up.

The MPA-40 is a mono public address amp. So it has one speaker output. You select the appropriate socket to suite the speaker type. The 4/8/16 Ohm outs are for various tpyes of Hi-Fi speaker. The 70 Volt is used for muzak in shopping centres, restaurants, and waiting rooms.




If you have a pair of 8 ohm Hi-Fi speakers, you can diasy chain the connections and then use the Com and the 16 Ohm connection.

Daisy chain means you take the wires from a pair of speakers. Connect together the wires going to red on one speaker and black on the other. This now leaves you with two wires going to the other red and black terminals on the speakers, but the ends in your hand are not connected to anything yet. Plug the black in to COM. Plug the red in to 16 Ohm.

The sound from the speakers won't be stereo. It will be mono because that's all the amp outputs. But both speakers will work so long as they're functioning units.

If you have two 4 Ohm home theater speakers then you can do the same trick. 4 + 4 makes an 8 Ohm load. Connect the red to the 8 Ohm output.

Don't be tempted to try to connect to multiple terminals. The amp isn't powerful enough to to run more that one speaker chain.

Hope this helps

You need a stereo receiver or Hi-Fi amplifier to drive these speakers.

The amp or receiver will have red and black speaker terminals to match up with the speakers. Use some speaker wire to make the connections.

Once the amp and speakers are connected, you can add a source. The source could be your PC, TV, games console, MP3 player.

Being a 500W amplifier, you need to connect speakers with 300W each. The correct method to connect speakers is red terminal of speaker should be connected to red terminal of amplifier & black to black. The left side to left side speaker & right to right speaker. There may be main & remote terminals. Main speakers are the speakers at local place of the amplifier & remote for remotely placed speakers. I do have Technics SU-V85A which is somewhat similar. Enjoy! A nice piece to listen.

There are four posts - two black and two red. They should be connected together, as shown in the picture. If you are missing the brass straps, simply use wire to reconnect the posts, black-black and red-red.

Then it's a simple matter of connecting the red (+) amplifier output to one of the red terminals, and the black (-) amplifier terminal to the black terminal on the KEF.

The KEF terminals can be seperated if you wish to "biamp" or "biwire" these speakers. Each black/red pair is dedicated to either the bass or the treble. For higher fidelity, some listeners prefer to run seperate wires from a single amplifier channel to each individual speaker input.

hi,
connecting right speaker.
1.connet the speaker cord with the plug to the speaker high freq right (R) terminal
2. connect the speaker cord with white strip to the speaker low freq right (L) + terminal and its black cord to the -- terminal

do the same for connecting the left speaker to the speaker high freq left (L) and speaker low freq left (L) terminals
ok

The illustration in the manual I found at retrevo.com isn't detailed enough to show the axial connection option, which would normally accept a banana plug inserted straight in if the opening is conductive and about 4mm wide. I suspect it is as they mention a "variety of wire connectors".

Their only illustrated example show bares wire ends inserted into a small hole drilled through the termial post and the red or black plastic piece tightened down to secure it.

WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with polarity coding.The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 5.
To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the – (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier, receiver and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.
