Balancing ground noise, isolation, microphone splitting and combining etc. $55. I can hear sound clearly coming through, but it is attenuated quite a lot, and it sounds like it is going through a high-pass filter. The transformers allow an AC input signal to produce a related AC output signal without the input and the output being physically connected together. I haven't ever bought one of their transformers, but if they are the same as the ones used in their amplifiers it is On 2020-03-15 8:31 AM, Tom Lewis via Groups.

Typically, audio transformer is driven by an amplifier and loaded by several thousand pF cable capacitance and high input impedance of line receiver. 5. Close. While the power transformer can affect the response or “feel” of the amplifier, it is the output transformer that can dramatically affect the tone of your guitar amplifier since audio signal is actually passing through it. The voltage step up (or down) is proportionate to the turns ratio. They are capable of stepping voltage levels up or down, input/output balancing, impedance matching, eliminating ground loops, and blocking DC while passing audio signal. $16.
