In an earlier article we looked at the issues involved in connecting multiple speakers to one amplifier. In this article we look at some of the practical ways of wiring four speakers to each amplifier left and right.

For example, it is normal to have your main HiFi amplifier in the lounge room. It is also common to want to have some speakers in the family room, outside patio or pool area and in the workshop or garage. If you need to connect just 2 pair of speakers to a HiFi stereo amplifier that is, 2 speakers to 1 ampsee my article on How to connect 2 speakers to 1 amplifier.

I have had many people over the years tell me it is easy to connect multiple speakers — all you have to do is wire the speakers in series. In reality this wiring needs to be duplicated for the right side speakers too. This diagram shows how to wire four speakers in parallel. It is the same as wiring each speaker directly from the amplifier, like this:. Wiring speakers in parallel is not a good way of connecting three, four or more HiFi speakers as it puts too much load on the amplifier as explained in earlier article.

Again this is not a recommended way of wiring four speakers although it will worknor is it very practical. Apart from the hassle of having to wire from one speaker to the next, if one wire is disconnected, then all speakers will stop working.

Also each speaker affects the total load seen by the amplifier which will only allow it to work up to one eighth of its potential. This is closer to a daisy chain as each speaker and corresponding single wire forms part of a daisy chain loop. This is a safe way of wiring four speakers without a switch box or separate volume controls. It is a combination of series and parallel. Providing all the speakers are 8 ohms, this will work as the total impedance is also 8 ohms.

While this will technically work, it is often not practical as you need lots of wires interconnecting all the speakers and there is no control over any one speaker — they all are controlled by the amplifier volume control at the same time.

The easiest and a safe way to connect 4 pairs of HiFi speakers is to use a 4 zone speaker selector switch.

This is relatively simple to wire, just run a wire from the central location lounge room to each speaker. The box should also look after any impedance matching to prevent amplifier overload.

It is normal to locate the selector switch adjacent to the amplifier. Remember to connect the lounge room speakers to one switch so they can be turned off when you only want music outside. Please note, speaker selector switches are designed for multi-room installs in a home.

They are generally suited for low power under watts amplifiers. They should be not be considered in a commercial install or for use with high output power amplifiers.

Speaker selector switches can use various techniques to allow multiple speakers to be connected to the one amplifier, namely:. All these methods allow multiple speakers, but at a lower volume than using just one speaker. This is logical as the signal is being shared by more than just the one speaker.

To see how the power is distributed by the different types of speaker selector switches, see my Speaker Selector Switch Simulator. If you are interested in using a speaker selector switch, check out my summary article on speaker selector switches — it discusses the features and uses in more detail, and summarises all the units bought from Amazon through this web site.

Disclosure: If you buy through these Amazon links Geoff receives a small commission from each sale. A more practical and a little bit more expensive way it to substitute the selector switch with a unit that also has volume controls. This allows the volume in each zone area with a pair of speakers to be controlled at the central location.If you have any problems opening files please read the download FAQ.

Have always sounded lovely to me. And I have to say that I do like the 70's McIntosh look better then their current look.

I currently use these with Martin Logan electrostatic speakers. Reviewed Feb 01st, by breeeze. The is a very enjoyable reliable amp for me the past few years. Recently, my amp started to sound a little dull, so I downloaded the schematic from HiFi and was able to trace the signal path through capacitors C9, C10 boardthat is commonly a 10uf electrolytic. I replaced these caps with large paper and oil caps that I had to mount on the forward metal bracket behind the glassand run lead wires to the points on the board.

I thought there'd be some hum or some side effect when I powered up-- but boy was I was wrong. In my experience, the 10uf electrolytic in C9, C even high quality audio electrolytic caps- hold back the 's potential. This is a fun reliable amp to own, and actually pretty easy to work on and modify using the schematic. I'd suggest anyone looking to add higher resolution and a more immersive experience from this amp, to address the capacitors that are in the signal path defined in bold on the schematic on the input section.

JimSmileyDec 13, The MC has good power, but I think it would really come alive with some higher-than-average-sensitivity speakers. And something at least a bit on the laid back side. Unlike electronics, I don't know that used speakers are always a great value.

The technology advanced a lot, and then the manufacturing advanced a lot. You can make much better speakers cheaply than way back in the day.

However, it is kinda impossible to help you without a lot more information: - What are your listening goals? Do you listen to jazz trios quietly? Motorhead at full crank? Organ recordings? Plan to get one? Which relates to - What form factor of speaker do you have in mind?

Big bookshelves? Only room for mini-speakers? As for the budget, money is money. Yet speakers really have a better yield curve than electronics: spend twice as much on electronics and perhaps hear some improvement. Spend twice as much on speakers and you should be able to get significantly better speakers.

Location: Singapore. As per the title I keep looking at a good amp, and, of course, McIntosh name and fame are very attractive. However, financially I cannot reach the new generation, neither the tube "big boys", but I've seen their first generation integrated amps at digerable prices. But they're 50 years old, different connections than today's standards, no protection for speakers, and the '90s to current day market has a plethora of options, in the same price range, both tube and integrated.

Does buying something like this worth it especially sonically? Thank you!

Johnny ActionSep 14, Location: New Orleans. No experience with them, but the name and vintage alone makes them desirable. I think they would have to be considered more for their collectability and cachet than their sound quality. I would think they could be easily bested by more modern gear, but I know there are many that are convinced that the old stuff is better.

Either way, be prepared to have them gone through. BayouTigerSep 14, Location: Loveland, Colorado. I'm using a Mac C 28 preamp with a amp and they make wonderful music together.
