![]() I don't know exactly what the consequences would be, but I guess a worst case scenario would be blown outputs?!Ī similar question was asked on AVForums and the advice was to buy a device that uses resistors or transformers to convert the stereo signal to mono, such as this one. My gut instinct tells me that plugging a Y-cable like this into the pre-outs of my 2ch stereo amp to convert stereo into mono is asking for trouble. This time, however, I want to feed each sub the same mono signal. ![]() Por otro lado, un sub-out está destinado a conectar subwoofers a receptores de A/V. When I used subs before I simply had two set up in a conventional stereo arrangement and fed them from the pre-outs of my stereo amp. La principal diferencia entre una pre-salida y una sub-salida es que la pre-salida es un puerto en un receptor A/V que se utiliza principalmente para conectar el receptor a un amplificador de potencia externo. Thanks in advance for any help you can provide.I'm thinking of giving subwoofers another shot to see if I can get them to eat my room modes. The sub out of the receiver is a single mono bass only output that has both the crossover frequency, that limits how high in frequency the woofer plays, and the level set in the receiver. You can use a subwoofer cable or a regular RCA cable. Which cable you opt for depends upon how you plan to connect. Do I just need to connect either the L or R from the "fixed" Pre-Out jack on the Preamp to the Subwoofer or should there be two RCA cables from the Preamp "fixed" Pre-out jacks to the the L and R input jacks on the Subwoofer? Step two of connecting your subwoofer to an AV receiver’s pre-out is selecting an appropriate cable that matches up with your setup and your connection type preferences. The design concept behind pre-out subs deals with what happens inside an amplifier as it moves towards outputting sound to your speakers. This Becker 4 channel pre-amp adapter cable provides four RCA outputs and sub output allowing the connection of an external amplifier and subwoofer. A pre-out sub arrangement does this efficiently without the more complicated procedure of modern-day amplifiers. Am I correct that the variable Pre-Out jacks on the Preamp should go the the Amp?Ģ. The pre-out sub concept is a unique way of doing what all amplifiers do, amplify. The subwoofer has an input for mono or L and R, but there is no mono out on the Preamp, just the L and R Pre-out jacks.ġ. However, the equipment came with only the one RCA cable for the subwoofer. That leaves the "fixed" Pre-out jacks for the powered HSU subwoofer (which has it's own volume control). I assume the Preamp "variable" Pre-out jacks should be connected to the Amp (since the Amp has no volume control). I need to connect it to a B&K ST1430 Amp and a powered HSU Subwoofer which were in the original setup. I have a Luxman TP-114 Preamp which has one set of L and R "fixed" Pre-out jacks and one set of L and R "variable" Pre-out jacks. I didn't unhook them so I don't know how they were originally hooked up. The main difference between a pre-out and a sub-out is that pre-out is a port on an A/V receiver that is mainly used to connect the receiver to an external power amplifier. Seems like a good option to use the sub filtering so the main speakers will not have to handle the low frequencies. ![]() I have inherited some "vintage" equipment and need some help with setup. Matias said: ADI-2 to SB-3000 with RCAs, and SB-3000 to speakers with RCAs as well, and let the sub handle the high-pass/low-pass filtering.
