The 2485 GoldMike MK2 from SPL is a discrete, Class-A, transistor-stage, dual-channel microphone and instrument preamplifier. Like its predecessor, the GoldMike Mark2 retains a hybrid solid state and tube construction to combine the best of both worlds.

Available as an option is a 24-bit, 192 kHz A to D converter.

The rackmountable GoldMike MK2 has updated tonal flexibility and versatility, making it a useful dual-channel front end for almost any modern production environment.

The GoldMike MK2 is the result of all our experience and knowledge from its earlier predecessor and it represents an improved, more flexible and modernized version.

We have added technologies that have already been proven to provide improved tonal results in other SPL products. For example, the instrument input is designed around a Class-A impedance converter which premiered in the SPL GainStation.
A significant contribution to the success of the predecessor was the hybrid preamplifier concept. It 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.

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. The is a discrete Class-A transistor stage crafted specifically for this preamplifier.

The degree of tube pre-amplification is no longer the fixed +6 dB value of its predecessor. The GoldMike MK2 sports the selection of three different tube pre-amplifications: +6 dB remains the standard and is complemented by +12 dB and +18 dB. This allows creative variety with the tube saturation and limiting effects.Experiment as you wish to achieve the sounds you are looking for.

We have also added an extra setting to the popular Flair circuitry to give increased flexibility to the "presence" improvement.

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.

Adjust the sound of your world with the GoldMike MK2.

Husky approved!
Color: Cheers
Got this for my large husky to wear for his 10th birthday. He didn't tear it up right away. The squeaker lasted longer than it does with most toys. He seemed to genuinely enjoy the toy. Removed the stretchy string once I got a few pictures so he wouldn't eat it. Very cute.

5 Stars - My Gentle Giant Loves It!
Color: Pawty, Color: Pawty
I got this toy for my German Shepherd, who is very gentle and loves soft plush toys. Even though he’s a big dog, he’s careful and enjoys playing gentle tug-of-war so the rope part as the string is perfect. The toy was a little smaller in length than I expected, but it hasn’t mattered at all — he absolutely loves it! It’s soft, thick, and has a squeaker deep inside that will make it hard for a dog to pull out. It is cute, and has held up well to a lot of carrying around and light tugging. If you have a gentle dog who loves plush toys, I definitely recommend this one. I would absolutely purchase it again! Fun little dog birthday gift.

Stupid cute!
Color: Crown, Color: Crown
My Lily looked so cute on her first birthday and it was so easy to put on. It doubles as a toy if you want to cut the band off. It's got a crinkling sound, no squeaker

Not for tough dogs who chew
Color: Pawty
My dog loves it! We play tug of war and it’s still holding up. She is 40 pounds and is strong. But this would not be durable for dogs who rip things apart.
