This invention relates to a ground isolation circuit for electronic circuitry and, more particularly, to a ground isolation circuit for isolating a plurality of signal channels such as in motor vehicle-mounted stereophonic sound equipment. Wiring diagram of loop powered isolator with external powered 4-wire transmitter: Note: This is a typical wiring diagram of a loop powered signal isolator (get energy from the input) and 4-wire transmitter, detailed parameters of loop powered signal isolator (ATO-S-SINIR-502E) are in the product page.This alternating current creates a current in the secondary of the transformer. An oscillator circuit alternately switches the current through each half of the primary.
A loop powered isolator is basically a center tapped transformer which has the input 4/20mA current flowing through its center tap on the primary.Your voltage stepup then 5V regulating circuit wastes a lot of battery power. Audioguru again said: The minimum supply for an ordinary old LM5455 or NE555 is 4.5V so your 3.7V (or less when it is running down) is too low.

It’s full feature set, rugged construction, and high-end specifications make the DTI the obvious choice.Rather than buying a ground loop isolator I bought a BT adapter that had it’s own power connection and built in ground loop isolation (since I was tired of HAVING to plug in the phone, rather.

The compact black anodized all aluminum case and it’s passive design allow the DTI to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. Whether you need an interface between a computer based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of a signal source from your recording equipment, or in many cases, just a safer connection between two audio systems, the DTI can accommodate.

This allows it to easily fit into virtually any audio system and be the clean patch point between all types of systems.
We have provided XLR, 1/4″ phone, and RCA type phono connections on all inputs and outputs. What further sets the DTI apart from other lesser isolation boxes is its connection versatility. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 ohms to 100k ohms. This gives the DTI a very clean and neutral sound with a wide variety of maintaining signal sources. The DTI’s audio transformers have an extremely flat and wide frequency response and can handle high signal levels while an isolated balanced output. The DTI (Dual Transformer/Isolater) is a high quality totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise.
