Take your audio experience to the next level with the EZ-HK1 Stereo Audio Hum Killer, a premium-grade stereo audio transformer isolation module. Designed specifically for use with high impedance, unbalanced audio inputs, this device ensures a clean, clear audio output free from any hum or distortion.
The EZ-HK1 features gold-plated RCA jacks for both input and output connections, ensuring optimal signal transmission for superior audio quality. The shield connection of each input jack is meticulously engineered to be electrically isolated from the case and from the output ground, further enhancing the audio clarity.
One of the standout features of the EZ-HK1 is its ground-lift switch, conveniently located on the rear panel. This switch connects the shield connection of each output jack to the case shield, effectively eliminating any hum caused by ground loops. This feature is particularly beneficial when the EZ-HK1 is installed between an unbalanced audio source, such as a computer, CD player, cassette player, or other consumer audio products, and the input of a grounded amplifier in an audio system.
In addition to its hum-killing capabilities, the EZ-HK1 also offers conversion between Mini-jack and RCA formats, providing versatility and compatibility with a wide range of audio devices. With its superior design and advanced features, the EZ-HK1 Stereo Audio Hum Killer is your solution for a hum-free, high-quality audio experience.
