Allen Avionics AGL-600-2 Audio Ground Loop Isolation Transformer

All transformers in the AGL series are true isolation transformers, designed for low distortion, linear phase response and excellent pulse fidelity. This is accomplished by extending the bandwidth to over 300 KHz (10 - 15 times the normal 20 KHz bandwidth). The extended bandwidth guarantees a linear phase response that provides distortion-free audio with no loss of its original harmonic content. The AGL-600 and AGL-600-2 includes aground lifter switch for the XLR connectors.

The AGL series of audio isolation transformers was designed to solve the common audio problems of hum, buzz, noise and unbalanced lines.

These problems usually exist at the output of an electronic device that is connected to another electronic device in such a way as to create a ground loop where common mode or EMI current can flow.

Hum in audio or video systems is usually the result of a ground loop in the system. Common mode current will flow in a ground loop created by an electrical system that has grounds at different voltage potentials. The result is 60 Hertz hum in the power amp output.

In a multiple device system, it is very important to determine which two pieces of equipment are the ones creating the problem. The AGL-600 or AGL-600-2 can be inserted between them to eliminate the hum.

When the audio system is operating and hum exists, disconnect one piece of the equipment at a time until the hum stops. Once you find the combination of equipment that creates the hum, you can install the AGL-600 or AGL-600-2 isolation transformer between them.

The AGL-600 or AGL-600-2 will stop hum, buzz and line balance problems. The 3-position switch will eliminate the need to cut pin "1" to lift the audio ground and the connection to the shield.

For audio systems using 1/4" mono jacks and plugs, use the AGL-10K (adaptors are available to RCA and 3.5mm audio connectors).
