Dual-channel microphone and instrument preamplifier

Like its successful predecessor, the GoldMike Mark2 retains a hybrid solid state and tube construction to combine the best of both worlds.
The transistor stage is composed of single transistors in a class A design. The circuitry is fully discrete, and each transistor is completely optimized for its specific task. You will not find any IC's in this preamplifier stage because they cannot be optimized for this specific application to the degree we at SPL aim for. This all new discrete class A transistor stage is a genuine innovation in the entire preamplifier market at this price level.

• Frequency response <10Hz bis 90kHz (-3dB)
• THD+N (Input level -30dBu, 30dB Gain) 0,016%
• Noise (A-w., R=40Ohm, 30dB Gain) -91,2dBu
• Dynamic range (30dB Gain) 110dB
• E.I.N. 128dBu
• Max. output level (sym., XLR+Jack) +26,8dBu
• Slew rate solid state stage 200V/µs

The GoldMike MK2's new features provide an amazing tonal flexibility and versatility, making it a perfect dual-channel frontend for any modern production environment.

• Discrete Class A solid stage
• Tube drive in three different intensity levels
