Adapter cable 2 x TRS to 2 x RCA / 3.3ft / 1m / black - audio jack to cinch - showking

Product Information

RCA cable can go a considerable distance. But until we know how far we need to go, we really can not say what the best choice is. Such shorting, if done on a higher impedance mic level signal won't likely affect anything. I've seen people do that on line level signal, but I'm not sure if they're aware about any long term effects that might exist.

I'm finding indications on-line that quality RCA cable is function up into the 30ft to 100ft (10m to 30m). I'm not sure I would use runs that long, but those are the numbers I'm finding. An unbalanced-to-balanced connection should use a 3-conductor (balanced) wire. The explanation behind this technique is somewhat complicated, and it is beyond the scope of this article. For an in-depth look at the technical explanation for this solution, read section 5.4, "Shield Wires", of The Clean Audio Installation Guide. ( http://www.benchmarkmedia.com/caig/ )

In this application note, we will show you how to design an active 2-way loudspeaker with the miniDSP 2x4 HD/Flex. Using the 2x4 HD/Flex, you can either create a conventional (Linkwitz-Riley or Butterworth) crossover, or a linear phase crossover.

There are three types of balanced outputs: 'impedance balanced', 'transformer balanced', and 'active balanced'. Each type of balanced output requires different considerations when connecting to an unbalanced load. With each case discussed, we will assume that 2-conductor (unbalanced) wire is being used, as 3-conductor wire will offer no advantages when driving unbalanced loads.

Oh no! Why did I get blocked?

Devices with impedance-balanced outputs actively drive the hot output only. The cold output is tied to ground via a resistor that matches (or balances) the output impedance of the hot signal conductor. In other words, there is no audio signal on the cold conductor, but, in a full balanced system, common-mode rejection will be maintained since the impedance is balanced between the two conductors. The "proper" way to do this, as you asked, is to use an audio transformer per channel. Pricey though. NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team.

Now for a balanced output, you can simply connect the + and GND terminals and ignore the -. This does not result in a "half wave" as was stated. Balanced signals work by transmitting 2 versions of the signal (completely out of phase with each other). On a devices input, the out of phase signal is inverted and the signals are now in phase and sum together. This provides common mode rejection (CMR) which is all designed at removing interference and improving SNR primarily to allow greater cable runs and premium quality for sensitive environments. Search common mode rejection for further details. One Rane Note was mentioned earlier, but they have a ton more and some specifically on balanced signals and CMR. Transformer-balanced outputs must have the cold output tied to the shield conductor when connecting to an unbalanced load. Using an XLR connector, this corresponds to tying pin-3 to pin-1. The hot signal conductor will be connected to pin-2, as usual, and it will carry the audio information. The shield conductor will be connected, as usual, to pin-1. I know I'm coming in late on this one, but other people might benefit. The statement that "all pins must be connected" is not true. It will depend on the equipment and whether you are connecting to an input or output. In many cases, it is a best practice to jumper + and - on an input when connecting an unbalanced signal to a balanced input. So, in this case, yes all pins would be connected.It might be either built inside or made as an outside box with separate power. The XLR shield and pin1 would need to be grounded to the chassis on the receiving side or the whole thing might be bolted to it. A company called THAT Corporation makes very good receiver chips that would fit this task and a module using those has even been a commercially available product at some point . Now the thing is that pins 2 & 3 in a balanced arrangement, never have a potential with respect to ground, just each other. The main reason why two wires aren't enough for a high-performance audio interconnect is that no matter what you do, there will be current caused by a different ground potentials and/or a real-world interference flowing through the shield conductor. Since the shield conductor has a non-zero impedance, this current will produce a voltage and in case the shield conductor also doubles as a signal conductor, this voltage will be mixed straight into your audio.

The maximum length for an RCA cable is limited by the cable capacitance, the source impedance, and the amount of induced noise. 12 feet is a common upper boundary for pre-made cables but I've built my own cables in the 20-some foot length." The connecting cable should have the cold signal conductor of the cable tied to ground at the source-side only (the unbalanced end of the cable). The load-side of the cable will be connected in a typical balanced configuration. The Flex balanced is balanced in/out. If you'd like to use an unbalanced amplifier (e.g. Powered subwoofer) downstream of the Flex series, here is the recommended TRS to RCA cable to minimize detrimental effect on the audio quality. Devices with transformer-balanced outputs actively drive the primary winding of the output transformer. The secondary winding of the output transformer delivers a symmetrical signal to the hot and cold signal conductors. If the receiver is made differential, i.e. it only cares about the difference between the two signal conductors (XLR pins 2 and 3 or hot and cold), the "dirty work" is offloaded to shield (or XLR pin1) conductor. As long as those are not connected to the PCB on either transmitter or receiver side (which causes so called Pin1 problem) but rather diverted to the Protective Earth mains conductor, this makes for a hum-free connection.It is clear from the original post that there is some Distance between the Focusrite Sapphire and the Stereo system, however, that distance is not specified. Until we know that, it is near impossible to say what the right choice is. Pin 1 (sleeve/screen) is always ground. Pin 2 (tip) is always the positive deflection. Pin 3 (ring) is the negative deflection, So if you ever reverse pins 2 and 3 you create an out of phase condition. If 25ft to 30ft is workable for you, then I think RCA. If you need more than that, then perhaps the Sescom adapters is the better choice.
