SPL GoldMike MK2 Dual-Channel Microphone and Instrument Preamplifier

SPL GoldMike MK2 Dual-Channel Microphone and Instrument Preamplifier Overview: 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 Class-A Preamp In the GoldMike Mk2 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.

Tube Preamp The GoldMike Mk2 sports the selection of three different tube pre-amplifications: +6 dB remains the standard complemented by +12 dB and +18 dB This allows creative variety with the tube saturation and limiting effects.

Flair The Flair circuitry makes use of the specific harmonical behaviour of coils This broadband filter adds a touch of presence that help almost any vocal to better stand-out in the mix.

Peak & FET Limiters The pre-output stage Peak and/or FET mode limiters can be used to protect an AD converter (optional) from clipping, or for example to add punch to drum tracks, which in turn reduces or in many cases even eliminates the need for subsequent compression PCB Layout Because the GoldMike Mk2 is a dual channel preamplifier, its channel separation is of fundamental importance for the stereo image.

Therefore the print-board layout is symmetrically mirrored around the power supply in the center from channel 1 to channel 2 This results in an identical signal flow to supporting a naturally balanced stereo image.

Additionally the print-board provides extra-large ground areas maximizing the shielding against crosstalk and interference Features: Discrete Class-A single transistor & tube preamps Tube drive in three different intensity levels Flair presence enhancement in two switchable settings Pre-output limiter stage: extremely fast diode-based operation, perfect for A/D converter (optional) protection Polarity Reversal 48-volt phantom power VU metering with three different, switchable display ranges Front panel instrument input, separate rear-side microphone and line inputs Custom-made, fully discrete, Class A op-amps VU meters with two switchable calibrations All switch functions are handled by encapsulated relays with gold-plated contacts Specifications: Frequency response: ‹10Hz bis 90kHz (-3dB) Input impedance: Microphone, XLR: 2.8kOhm Line In, TRS: 10kOhm Instr.
