![]() ![]() The user audio source, such as a computer, CD player, cassette player or other consumer audio product, connects to the input. The shield connection of each output socket is connected to the case shield. ![]() The shield connection of each input socket is electrically isolated from the case and from the output ground. The AV-HK1 is supplied with two adapter cables to facilitate connecting with products that use miniature jack plugs and sockets.

The independent Ground Lift switches on the outputs takes this one step further by lifting pin-1 on the XLRs. ![]() Computers, CD players and other consumer equipment can be noisy – this is particularly true when incorporating audio with a projector – so isolation transformers can be very useful when combating system noise. The ISO-2 is equipped with output isolation transformers to eliminate hum and buzz caused by stray DC voltage and ground loops. The balanced output of the ISO-2 is line level, meaning that it should be connected to the line input of a mixing console.Įliminating hum and buzz and the ground loop ![]() Balanced or unbalanced output signal can be connected to the input of ISO- 2 the isolated outputs will always be balanced signals. The I SO-2 has two combination XLR/TRS input connectors, wired to the AES standard pin-1 ground, pin-2 hot (+), pin-3 cold (-). Whether an unbalanced or balanced signal is connected, the ISO-2 will automatically convert the signal depending on the type of cable and connector plugged in. The ISO-2 can be operated as a dual input and outputs, and since the circuit is passive, no power is required. The ISO-2 accepts unbalanced or balanced signals and is equally suitable for consumer electronics and professional line-level devices. The ISO-2 is a passive audio isolator designed to be inserted into the signal chain to block hum and buzz caused by ground loops. ![]()
