SPL Audio Gold Mike Mk2

Dual-Channel Microphone and Instrument Preamplifier

SKU: SPL00054 Categories: , , , Tag:


The GoldMike Mk2 combines Class-A transistor with a tube preamplifier.

The transistor stage is composed of single transistors in a Class A design and works in series with a tube preamplification stage that provides 6dB to 18dB of tube gain for subtle to more obvious saturation effects.

A significant contribution to the GoldMike Mk2 is the preamplifier concept that combines transistor and tube preamplifier stages and specifically utilizes their technological and sonic advantages: The efficiency and low noise of a discrete transistor stage is enriched with musical coloration of a tube stage.
