  • Page 1 VAC Renaissance Signature Preamplifier Mk II Operation & Maintenance Information Valve Amplification Company Manual issued 8/20/2002 Revised 08/09/2006, 07/12/2007...
  • Page 2 CAUTION THE POWER SUPPLY UNITS CONTAIN NO USER SERVICEABLE PARTS. DO NOT REMOVE THE COVERS. LETHAL VOLTAGES ARE PRESENT WITHIN THE CHASSIS. NEVER OPERATE THE PREAMPLIFIER WITH THE AUDIO CHASSIS COVERS REMOVED. BEFORE OPENING TO CHANGE TUBES, DISCONNECT THE PREAMPLIFIER FROM POWER AND ALL OTHER COMPONENTS, AND ALLOW IT TO SIT TURNED OFF FOR 30 MINUTES.
  • Page 3 INTRODUCTION The Renaissance Signature Preamplifier is the world’s finest audio preamplifier and an absolutely unique component. Its unusual topology, premium parts, and flexibility make it a pleasure to hear and operate. The line stage is, in effect, a small Class A1 power amplifier, capable of driving loads as low as a few hundred ohms.

  • Page 4: Installation

    INSTALLATION Provide adequate ventilation. Do not operate on carpet or any other surface that might block air flow. The chassis will become warm in normal use. Do not allow the chassis to touch any metal parts, such as the frame of an equipment rack.
  • Page 5 INPUTS (back panel) There are five line inputs. Three pairs (L1, L2, L3) have RCA jacks to accommodate unbalanced line level sources. The other two inputs (L4, L5) can accept either RCA unbalanced or XLR balanced sources; by each of these sets of jacks is a toggle switch that must be set to the correct mode.
  • Page 6 OUTPUTS & GROUNDING SWITCH (back panel) One pair of RCA jacks provide line level output to a tape recorder. The level of signal is not adjusted by the volume control. Two sets of RCA output jacks are provided as main outputs to power amplifiers. In addition, one pair of XLR jacks can be used to drive a power amplifier.

  • Page 7: Operation

    Optimum sound should return after a few hours of operation, preferably with an audio signal. Please note that although your VAC System has been run for 48 hours at the factory, it will continue to "break in" for approximately 150 hours. Also be aware that many components display the need for a new break in period after being transported in unheated cargo aircraft.

  • Page 8: Front Panel Controls

    FRONT PANEL CONTROLS Although most of the front panel controls (Volume, Power, Mute) are self explanatory, VAC has outfitted this unit with several advanced features which bear further description: Phono Section: When fitted, input “PHONO" is connected to a discrete, pure tube phono preamplifier, providing 44 dB of gain, suitable for use with MM (moving magnet) and many high-output MC (moving coil) cartridges.

  • Page 9: Remote Control

    REMOTE CONTROL The remote control allows for wireless adjustment of MUTE and VOLUME. The remote wand is powered by two “AAA” batteries. These should be of the alkaline type. You will need to install them in the wand before using the remote. Since batteries can leak, they should be removed from the wand if it is not going to be used for an extended period of time.
  • Page 10 Right Left Right Due to the unique nature of the VAC Signature, we strongly recommend that you use only tubes specifically selected and tested by VAC for this application. DANGEROUS VOLTAGES EXIST WITH THIS COMPONENT. YOU MUST FOLLOW THESE STEPS TO PROTECT YOUR SAFETY.

  • Page 11: Care Of Chassis

    Use of a coarser cloth or failure to otherwise protect the faceplate may result in damage to the finish. VAC is not responsible for cosmetic damage resulting from improper care or packing.

  • Page 12: Warranty

In addition, if the registration form is received by VAC along with a copy of your sales receipt from an authorized VAC dealer within this thirty days, a service contract will be extended to cover your equipment for two (2) years (tubes excepted).
