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.

If you work in the professional audio field, you need to use balanced lines for long signal runs to prevent hum and noise pick-up. This Balanced/Unbalanced Converter is really two projects in one. It can convert an unbalanced input to balanced outputs and vice versa. Specifications: Signal to noise ratio: -100dB with respect to 1V output, 4.7kW input load.

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 …

Luckily, most have low output impedances and offer very high signal levels, making them ideal for connecting to the balanced inputs of powered speakers, via an unbalanced to balanced converter like the TCI. TCI was designed for studio applications and so has ¼” jack input sockets and not RCA phono sockets, normally found on hi-fi equipment.

Performance is especially poor when cables are long, since the entire interface is unbalanced, allowing both audio and ground noise to flow in the cable shield. A far better hookup shown in Figure 2 uses shielded twisted-pair cable to take advantage of the noise rejection available from the balanced input stage.

“Line-level” signal level for consumer audio equipment is nominally -10dBV (0.32V RMS). However, “line-level” signal level for pro-sound equipment is +4dBV (1.23V RMS). Simply put, pro audio gear is looking for a 14dB higher signal level. 0.32 v rms vs 1.23v rms. Where balanced outputs are always 4 times the voltage of consumer audio.

Standard line level for unbalanced is about -10dB. Balanced line level is +4dB. So you should need a gain of 14dB. I did this using a 5532 op amp (balanced supplies). Make one op amp your gain stage and feed the inverting input of the second op amp (configured for unity gain). Take the outputs of both op amps for your output.

I want updgrade Bmw HIFI Logic 7 amp. Problem is engine noise if I connect direct RCA on TDA8566Q balanced input. So I decide build low noise pream wich will convert balanced to unbalanced signal. I dont want to use audio processor is too expensive, Hi-Low converters I dont like too (poor audio quality), so I think the best solution make converter.

This produces an unbalanced output that can be used to feed an unbalanced input via either a TS or TRS plug. It can also be used to feed a balanced cable and input via a TRS plug. The impedance balancing means that the balanced interference rejection …

Good evening Im trying to build a small but low noise balanced to unbalanced audio converter. It should also amplify the signal. The non-inverting amplifier far right is just optional to increase the signal.
