The VariOhm is connected between the microphone and the microphone preamp, either the built-in preamp of a mixer or an external mic pre may be used. The concept behind VariOhm is that impedances of microphones and preamps vary considerably. The resulting impedance relationship is a key factor in determining the sound and tonal characteristics of the audio. The central element VariOhm uses are custom-built transformers. These impart much sought after audio characteristics associated with great analog sound.
The desired settings are found by using the impedance control knob and by auditioning with the Bypass switch. Different settings for different tone colors and bite are available to fit different applications. VariOhm may be used with all types of microphones; dynamic, FET, tube condenser or ribbon. Other features include a “hardwire” (i.e., no active components present) bypass to ensure accurate comparisons of the input signal, a phantom/off switch and a phase/reverse switch.
The VariOhm lists for $299 MSRP and is expected to “street” at $260 USD.
