Overview[ edit ] Bridged or paralleled modes of working, normally involving audio power amplifiers, are methods of combining the output of two identical amplifiers to provide, what is in effect, a mono amplifier. Combining more than two amplifiers can be effected using the basic principles described, including the possibility of bridge and parallel modes in combination. Two identical amplifiers are most often encountered in a common case, with a common power supply, and would normally be regarded as a stereo amplifier. Any conventional stereo amplifier can be operated in bridge or parallel mode provided that the common loudspeaker terminals normally black are connected and common to the ground rail within the amplifier. Some two channel amplifiers, or stereo amplifiers, have the built in facility to operate in bridge mode by operating a switch and observing the input and output connections detailed on the back panel or in the manual. This option is most often found in high power PA equipment or amplifiers designed for car audio applications. Operation in parallel mode requires no special facility and is implemented merely by the appropriate external connection. Where two channel amplifiers have separate controls, and are switchable to bridge mode, only the controls on one channel will be operational.
How to Connect a Subwoofer to an Amplifier
Let me say right up front that you only need to read this article if you are lucky enough that your group is getting bookings in large or outdoor venues. But if you have a good set of main PA speakers that are starting to sound strained at those large gigs, you might want to think about a next logical step. You can send comments, questions, or scathing diatribes to Larry at lmundy attbi.
Subwoofers have different impedances (Dual 4 ohm, Single 2 ohm, etc) that change your wiring options when you add or subtract woofers. Amplifiers also have limitations on your final impedance, so the subwoofers and amplifier must have the same final impedance to be connected.
To try to get this working, I recently purchased a secondary amp with RCA inputs to power the extra speakers. The additional speakers 5 pairs are mounted in the ceilings throughout the house. I also have a speaker selector box so that I can select which room or rooms I want to send the sound to. The output can be mono. I just want some sound to the other rooms. Any ideas short of buying a new amp with a 2nd zone output? Thanks, -Rich DiPietro Hi, Rich, This is a question that we get from time to time for various receivers so I’ll answer for your specific receiver but will also give suggestions that would work for any receiver.
Obviously the best option to accomplish what you are trying to do would be to use a “Zone 2” line level output or a “B Speakers” speaker output if your receiver had either of these which it doesn’t. But there are other options. On some receivers, there are “tape output” or “preamp” outputs that could be connected to an external amplifier like the one you bought to drive the additional speakers. That output is turned off by default. To turn it on requires a trip to the Set-Up menu.

I feel this information will be important to the owners of these superb amplifiers. There’s very little editing: I want to call attention to both you and owners of the Canary CA , a moderately inexpensive vis a vis very expensive premium B tubes way to kick up the performance of these amps. Having just brought another pair of them into my showroom, I decided to leave the stock Electro Harmonix B as is. For less money than a pair of KR B’s these amps take 2 pair each keep in mind , the changes were breathtaking.

Some equipment, especially amps, have multiple OHMS ratings. But what does it all mean, and why is it all so important? OHMS are a way of measuring Resistance. Resistance is the measurement of an electrical device or circuits ability to flow electricity. Low resistance means the device is able to “pass” more electricity, high resistance means it “passes” less. Resistance is a Static measurement it does not change.
Speakers do not have a resistance, as whilst the cone moves the effect of the magnets in the motor causes the resistance to change. Impedence is also known as Speaker Load. OK so now you understand what OHMS are and how they related to the speakers impedence, how does that help? It helps you determine which speakers are going to be suitable for your equipment!
As we know, LOW Impedence means more power passes from the amplifier to the speaker making it louder, and vice versa. Visit this article for the video version of this article. But first lets familiarise ourselves with different audio configurations: Amplifiers which support Bridging allow you to “team up” two channels to increase the power.
How can I get two subwoofers in stereo?
How to Wire 2 Subwoofers on a Mono Amplifier by Nichole Liandi If you’ve got a mono amplifier, you’ve got a great opportunity to really bring on the bass. Mono amplifiers are especially well-suited to wiring to two subwoofers. To wire two subwoofers to a mono amplifier, you need only know how to cut wire, use very simple tools and follow basic instructions. Cut two lengths of speaker wire. The first should be long enough to reach from the amplifier to the first subwoofer, and the second long enough to reach from the first subwoofer to the second.
Connect one end of the first length of wire to the speaker output terminals of the amplifier.
Danny, You wire two DVC 4-ohm subs to an amp that can handle a 1-ohm load like this, If you want to utilize the amp’s dual-terminal set-up, you can disconnect the positive and negative leads of Sub 2 (in the diagram) from Sub 1 and connect them to the positive and negative terminals of the amp.
Their Reference linestage preamplifier line remains a coveted commodity among ARC enthusiasts, and the Reference 6 linestage preamplifier solidly continues this tradition. More than a pretty face On the outside, the REF 6 sports some eye-catching changes. First, ARC is updating the aesthetic of the Ref line. A clean, modern appearance moves away from the classic, more industrial ARC look. The visual design of the REF 6 comes straight from the desk of Livio Cucuzza and his team, the ones responsible for the trend setting aesthetic of the highly popular G-Series.
Tastefully integrating style cues from the past models with a more modern look and better finish work, Audio Research components finally look as good as they sound.

Integrated amplifiers Looking back at the signal chain music must pass through, the next area to consider is the pre-amplifier. A stereo integrated amplifier is essentially a pre-amp and power amp in one box. A dedicated stereo amplifier will give a cleaner sound, due to it containing less electronics that can cause interference. It will have its own power supply, again giving better performance. The laws of economics also help us:
Nov 21, · If the subs are SVC 4ohm subs, then they will work just fine with this amp – run the +s from both subs to the + on the amp, and the -s from both subs to the – on the amp. Now if you have DVC 4ohm/coil subs then that amp is too small, you’ll have to wire the subs in series and then parallel them to the amp (4ohm load) so they’ll be sharing the w rms, so they’ll be running at half : Resolved.
Always a pleasure when people appreciate the time! Quote – ” To clarify, when an amp says 2ohm stable stereo, it really is saying that each channel can handle 2ohms for a 4ohm load rather than each channel can handle 1ohm for a 2ohm load right? On the face of it, 2 Ohms stable means guaranteed to work down into 2 Ohms without causing damage to the Amp, or limiting it’s full power into 2 Ohms.
It ” should ” also mean that it’s capable of tolerating the expected impedance dips that can take it lower than 2 Ohms. Whether a particular Amp does or not, should be obtained from the manufacturer in writing. Or maybe from a Reputable test in some mag or online etc. As i mentioned before, unless you are trying to run the Amp at anywhere near full power, you ” should ” be ok.
how do I connect my own subwoofer?
Whether it’s an installation that might not have gone as planned, or a random problem that comes out of nowhere. Here is a list of your common car stereo problems, symptoms and solutions to help get your stereo up and running! Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however; it is not compatible with aftermarket units. If you have a voltage meter or a test light, test the ground black , constant 12v yellow , and accessory 12v red wires to make see if you have the correct voltage in the correct wires, as well as a good ground.
Constant will always be 12v, whether or not your car is on.
If you have a passive sub or your amplifier lacks a “Sub Out” jack, you can connect the amplifier and subwoofer like you’d connect two speakers. Use the Main (Left and Right) speaker output terminals on the amplifier and connect to the subwoofer’s speaker inputs.
Speaker Connections for proper impedance match A note about amplifiers: You should always use the recommended load for your amplifier. However, if you must use a load other than the recommended load, here is a short guide. Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load. Therefore, you can usually use a load that is higher than the recommended load. Do not use a lower impedance load, as this could cause serious damage to your SS amp.
On the other hand, most tube amplifiers need a load to avoid transformer or tube socket damage. If a mismatch can not be avoided on a tube amp, it is better to go towards a lower impedance rather than too high of a speaker impedance. This may stress the tubes some, but, tubes are cheaper than transformers. As the graphic shows, you connect the positive wire to speaker A’s positive terminal, connect a wire from speaker A’s negative terminal to speaker B’s positive wire, and then connect the negative wire to the negative terminal of speaker B.
You could continue this string for as many speakers that you have available, however, it may not be very practical.

Contact Us Improving Stereo Performance of a Surround Sound Setup — Part 1 I hear and read of numerous reports from people with surround sound systems, that are not performing as well as desired for stereo music playback. Some are people who sold their old stereo setup, jumped on the surround sound band wagon, and now miss the musical qualities of their previous system. Others have started out with a surround sound system, but underestimated how much music they play and now find their system lacking in this department.
In both cases, people have fallen for the marketing hype that more channels is better, 5. So why do surround sound systems have such poor stereo performance compared to a stereo system? There are several reasons:
