Sutherland KC Vibe MC/MM Phono Preamp – Trickle Down Technology including exceptional 48 Volt Powered Board delivers Superlative Sutherland Sound!

Audio Revelation is an authorized Sutherland dealer.

Overview

Sutherland KC Vibe MC/MM Phono Preamp
In the assembly area, there are 100's of parts bins that hold the individual components for all the Sutherland products. All carefully selected, over the years, for solid performance and proven reliability. Of course, many of the components find their way into more than one model. Most everything in the Sutherland KC Vibe MC/MM Phono Preamp comes from that SAME stock of premium parts. We only had to add 5 new parts bins to build the KC VIBE circuit boards !

• 2 new values of polypropylene film capacitors
  (but still Wima brand, imported from Germany)


• 1 new value of electrolytic capacitor
  (premium, high reliability, very low impedance)


• 2 new op amps
  (both audio specialized Burr-Brown)


• Printed circuit board
  (same supplier and specs as more expensive models)


• Metal work – cover and base
  (Same supplier and specs as more expensive models)

 

AND MORE Sameness:

• The circuit topology very similar (a little simpler)


• The passive RC filtering/power isolation approach (a little simpler)


• The same attention of design details built by the same assembly people with the same care and craftsmanship.


• So enjoy the NEWEST Sutherland phono preamplifier. The KC VIBE.

 

KC VIBE – The Power Supply Advantage

It is a well accepted premise that high-end audio performance requires exceptionally good power supply design and execution. Energy from the power supply is the foundation for constructing the output signal. All too often, you will find cost cutting compromises that undercut any possibility for fulfillment.

Those commonly used out board (the pejorative would be 'wall wart') power supplies are a good example. Their limited power, limited filtering, limited regulation, limited output voltage and limited quality suggest --- well – limitation in delivering the required, quality power foundation.

The worst bad choice is a low output voltage. Many have outputs of 12 volts, maybe 24 volts. It is too little or, at best, leaves no margin for filtering or regulation. A good audio circuit would need at least 24 volts AFTER regulation/filtering. There is no excess capacity to insert an effective filtering function. Performance is already compromised, no matter how good the audio circuit may be.

THE 48 VOLT ADVANTAGE:

The KC VIBE uses a 48 volt board power supply. THAT key choice gives an opportunity to get a very good power foundation for the audio circuit.

• Limited power ------- fixed. The 18 watt power supply is loafing to meet the 2 watt KC VIBE power requirement.


• Limited filtering ----- fixed. Filtering is no longer determined by the external power supply. Within the KC VIBE, an extensive, passive RC filtering network completely removes any incoming residue. Completely isolating the audio circuitry from both the AC power line and outboard power supply.


• Limited output voltage --------- fixed. The 48 volt source gives a huge margin for extensive filtering and isolation. A full 30 volts of quiet, clean voltage is available for the audio circuits.


• Limited quality ---------- fixed. The KC VIBE power supply is rated for over 500,000 hours MTBF (Mean Time Between Failure). In accordance with Military Spec MIL-HDBK-217

SHORT VERSION:

The 48 volt power supply gives plenty of room for effective filtering, isolation and regulation. The audio circuit gets the voltage and power quality it needs for performance.

Phono Preamp Basics

A basic turntable produces a low level signal. It must be amplified and equalized before going to a line level input (sometimes labeled AUX) of  a preamplifier or receiver. That is exactly what the KC VIBE will do for you. The small signal from your turntable goes to the IN jacks. The larger, amplifier signal leaves the OUT jacks and goes to your line level preamplifier. There is also, generally, a grounding wire coming from the turntable.  It connects to the ground screw on the back of the KC VIBE.

Loading Adjustments

There are five available load settings. Loading is set using the supplied, gold plated shunts. There is a setting header block for each channel. Position the shunt to the desired load value. Be sure to set the loading of each channel to the same value. For moving coil cartridges, a good starting value is 200 Ohms. With moving magnet cartridges, 47k Ohms is generally recommended.
