The following data, taken from the THD test circuit on an Audio Precision System One using the internal 80 kHz noise filter, demonstrates the typical performance of a balanced pair system based on the SSM2142/SSM2141 chip set. Both dif-ferential and single-ended modes of operation are shown, under
Design of High-Performance Balanced Audio Interfaces
https://www.jhbrandt.net/wp-content/uploads/2014/11/Design_of_High-Performance_Balanced_Audio_Interfaces.pdf
The purpose of a balanced audio interface is to efficiently transfer signal voltage from driver to receiver while rejecting ground noise. Used with suitable cables, the interface can also reject interference caused by external electric and magnetic fields acting on the cable. The true nature of balanced interfaces is widely misunderstood.
Balanced-Unbalanced Converter For Audio Work Circuit Diagram

These balanced connections use 3-pin XLR plugs and sockets and screened twin-core cable. Block diagram: Block diagram shows the basic arrangement. Basically, the audio output signal is coupled to two separate amplifiers and these drive the two signal leads in the cable in anti-phase (ie, the signals have opposite phases).

This audio-balanced line driver project enables to drive hundreds of feet in length of cables without becoming unstable The project is based on the THAT1646 chip, which is a new generation monolithic differential line driver that offers improved performance over conventional cross-coupled designs. Based on high performance, fully differential op-amp exhibits low noise …
Balanced Line Driver & Receiver

Figure 1 represents a typical balanced audio-transmission system with a line-driver circuit that transmits two complementary audio signals (V S and –V S) over a shielded twisted-pair cable to a line receiver. R S1 and R S2 represent the output impedances of the line driver. Figure 1 also shows a line receiver where R IN1 and R IN2 represent ...

Assemble the circuit on a good quality PCB. The circuit can be powered from 12V DC. At 12V supply, a 600 ohm impedance line can be driven at +10dBm with a distortion less than 0.05% at 1kHz. Gain of line 1 can be set using the equation, Gain1 = (R5+R6)/R6. Gain of line 2 can be set using the equation, Gain2 = (R7+R8)/R8.

Balanced Audio Circuit. This is a typical transformer balanced audio circuit. As you will notice, special audio transformers isolate the audio from any part of the ground or chassis. The circuit on the left is the audio source (output) and the circuit on the right is an audio input. This eliminates the possibility of AC hum or buzz from being ...
