Your local A/V guy is confused. Yamaha RX-A2020 AV Receiver Backpanel - notice the highlighted main front left/right preamp outputs. Think of the old receiver as a multichannel amp with lots of fancy controls that should be ignored. If you're fortunate enough to own an A/V Receiver that has preamp outputs to connect an external amplifier, then doing so is quite straightforward. An unbalanced connection uses an RCA jack, and you would use cables with RCA jacks on both ends to connect your pre/pro to the amp. This is arguably the most complicated part of using a speaker selector, so I'll break it down for you: I have no idea why some manufacturers specify a direction on their cable jackets. Normally, such things are marketing hype, but I see no marketing benefit to this. If you want to calculate how much more perceived loudness you can potentially achieve by adding external amplification simply pull out the scientific calculator and plug in the following: dB(gain) = 10*log (Pext amp / Preceiver)  where dB is log base 10 and P is power in watts, So if you're running a 100 watt/ch AV Receiver and upgrade to a 500 watt/ch external amp, then you simply plug into the formula as follows:  dB(gain) = 10* log(500/100) = +7dB, Equal Loudness Curves - courtesy of Hyperphysics, Editorial Note about Equal Loudness: Otherwise, you need to make special cables as described in this excellent article about audio-system connections from Rane. However its only stereo. You would use a headphone to RCA adaptor and plug it into the RCA inputs on the amp. This process is called gain structuring, which maximizes the gain (amplification) while minimizing noise. Check your wiring one last time as explained in the steps above. A wire cutter/stripperis essential.

Then connect the speakers to amp. Are you running your speakers full range, or are you running bass management and redirecting the low frequency content to a dedicated powered subwoofer? The positive speaker terminal (red) on the receiver or amplifier must be connected to the positive terminal on the speakers, and the same applies to the negative terminals on all the equipment. The connection from receiver is achieved with rca jacks and an interconnect cable. Just as you proposed at first, you only need to connect the appropriate preamp outputs of your new receiver to preamp inputs of your old receiver and connect the old receiver's speaker binding posts to appropriate speakers. Also, what if the A/V receiver only has 5 channels, but you want to eventually want 6.1? Whether your amp uses balanced or unbalanced connections, connect each output channel from the pre/pro to the corresponding input on the amp. Connect the power cable. A subwoofer with speaker-level inputs is especially easy to connect to your older amplifier or receiver! The surround amplifier (or receiver) needs to have pre-outs for the front-left and front-right speakers that bypass the unit’s own power amplification and output an analogue signal to the stereo amp. Using balanced connections can help reduce the risk of ground loops, but only if each device's ground is properly implemented. When you increase the treble or bass, that is happening in the pre-amp. Hi, I am planning on hooking up my Alpine MRV-M500 amp to hook up my sub to my stock stereo. If your receiver has pre-outs, you send the signal to a power amp from the preamp outs. Make sure both the subwoofer and the amplifier are turned off and disconnected from the power … If there were an inherent directionality in the cable, the electrons would have an easier time moving in one direction than the other, which, I imagine, would degrade the audio quality. Hook up a home stereo to an amp with standard audio cables. This means that you can hook up any external amp to any pre out and the rest of the surround speakers can run on the interneal amp via speaker terminals. Ground loops occur when the grounds of two connected devices are connected along two different paths—the audio connection and something else, such as the AC cords—and those two ground connections are not at the same voltage. The speakers are then connected to the power amp. The speakers are then connected to the power amp. hi, i a'm thinking about car sub and car class d amp in home, can't i just use a car battery, and constant trickle charge, i can see, this seems complicated, or just a higher amp a/cxd/c converter like 50-60 amps at a 300 watt car amp, to power my sub, signal directly from sub out on receiver If you are a middle-aged woman looking to have a good time dating man half your age, this advertisement is … I purchased a lepai preamp to connect t: Can i connect a receiver to a preamp component? Make sure the volume on your pre/pro is at its lowest setting, or better yet, just turn it off. Pre-outs are pretty common on AV amps above £500 (we’ve listed some current models below). Make sure you get one that's long enough, and the longer it is, the beefier you want it to be. But there again I think you would be stuck with basic stereo only. Denon confirmed that the pre out terminals and the internal amp is live in parallel. Preamp connections to power amps: How to Connect My Sub to My Preamp: I have a passive subwoofer that I would like to hook up to my sony str-dh550 receiver. And you may need a laptop or tablet to read the instructions or watch the how-to videos you'll find below. This diagram shows how to integrate a tube amp with a Niles HDL-6 speaker selector. Not only is the sub "gentle" compared to a powered subwoofer, but your front speakers will be weaker as a … As I mentioned above, the two signal conductors carry the same signal, but one is out of phase with the other. These aren't overly complicated. You simply need to be aware of them: Receiver or Amplifier Power Output. Speakers that dip into the 4 ohm range at low frequencies tend to demand a lot of power from an amplifier. However, your hearing acuity will decrease with time and you will have to adjust the volume then. Attach the power cable to the positive battery terminal (not directly to the … An amplifier rating really depends on many things like the bandwidth it’s being rated at, the impedance it’s being tested at, and the specified distortion level. The receivers will easily connect to the power amps using rca cables (audio line-out of the Onkyo to power amp line-input) but unless your buying some fairly hefty speakers it's unnecessary to buy seperate power amps (the speakers should be rated to match the impediance and power of the amps. Conversely, finding a separate amplifier capable of driving complex 4 ohm loads with authority isn't too difficult, and isn't necessarily an expensive proposition either. You will need to select the proper gauge kit for your amplifier. How to Properly Hook Up a Car Amplifier Inside the House: Hello everybody, recently i bought car amplifier for repair and decided that im gonna replace my Sony XM-4020 that i have been running as my subwoofer amplifier for a year now. That's how the subwoofer gets its power and generates bass in this configuration. Some dj amps have a barewire hook up on them so you can hook it up using the same wires as you would with your car amp. When you increase the treble or bass, that is happening in the pre-amp. They are in fact just guidelines based on common sense and experience, so please use them as such. Then, at the other end of the cable, connect the red conductor to the red terminal of each speaker and the black conductor to the black terminal.). Audio signals are AC—alternating current—so electrons travel in both directions along the conductive pathway. There are two types of connections on any power amp—inputs that accept line-level signals from the preamp/processor and outputs that send the amplified signal to the speakers. Join the leader in rapport services and find a date today. Be sure that the connections are firmly and correctly placed. Now that you know the power rating of your receiver or amp, it's time to see how much of an impedance load it can carry. A power amplifier is a type of amplifier that supplies power to one or more speakers; it does not have the extra features and connections you often find on a home theater receiver, such as a radio, input source switching, and audio/video (AV) processing.The only control you typically find on a power amplifier (apart from an power switch), is a primary gain control, which is analogous to volume. If you must connect balanced to unbalanced, you can use a transformer to isolate all unbalanced connections, as shown above. So, in that way, using a separate amp to power some of the speakers increases the amount of power that remains for the other channels that are still being powered by the receiver. I want to hook up a second amp and power one set of front mains by the second amp, and the other set with my receiver. Of course if the budget allows, it's always a good idea to buy more power. I have a Sony es seperate 5.1 amp. Connect the subwoofer output to the amplifier input. Here is a quick procedure to ensure the trim controls are set optimally. Connecting power-hungry speakers to a receiver can cause it to overheat or break down, so this is when an amp comes in handy. If you want to use the full function of the preamp in the receiver and by-pass or replace your main preamp, then you can connect the preamp outputs of the receiver to the power amp inputs.
