Devices with active-balanced outputs actively drive both the hot output and the cold output. The signal on the cold output is an inverted (polarity-reversed) version of the signal on the hot output. This creates symmetrical signals between the hot and cold outputs. This is the topology of all Benchmark equipment. Digital Audio Processor — Flex based on the I/O configuration selected. No Dirac Live license for default configuration Balanced outputs are very common on professional products. Unbalanced inputs are very common with vintage equipment and consumer electronics. Establishing proper inter-connections between balanced and unbalanced equipment is imperative for the performance of the system (and may also prevent damage to the equipment). IF you are going to do a XLR to RCA conversion, then a Transformer based device, as we assume the Sescom is, would be the best choice.
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.Unbalanced connections (RCA; ¼" TS) have two signal conductors: hot and shield (the hot signal conductor carries the audio 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. 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. 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. So I would go ahead and do it the way you intended. If there is no hum or buzz, then you are fine. If there is then you should formally float the line as I described.
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. A more sophisticated connection may be needed for aggressive common-mode rejection, which may require modifying the equipment. For information about this type of setup, refer to the "Shield Wires" section (5.4) of The Clean Audio Installation Guide. by my mixer to sort out those awkward "where did the signal go" moments during bouts of finger trouble or whenAs you can see opinions vary greatly on this matter. But I would say if you get good quality cable, you are safe if you are in the roughly 25 foot or perhaps 30ft range. 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. Understanding LDAC™ Wireless audio The second "stereo" adapter is an unknown. It may be designed as an adapter to send a mono RCA signal to both stereo channels of a stereo TRS input. In that case the tip and ring would be connected together. If it's wired that way it won't work as a mono TRS to RCA adapter when connected to a balanced output. It may be wired with the Ring open. If so it will work as well as as TS adapter when connected to a impedance balanced output, but not at all if connected to a transformer balanced output.
The best one from a technical standpoint: retrofitting a XLR differential input to a legacy equipmentNote how the TRS side is only connected with Tip and Sleeve while RCA side is not using the shield. In this app note, we will demonstrate subwoofer integration for miniDSP'sstereoDirac Live processors using only the Dirac Live app for measurement 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. 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." 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.
