  • Page 5 For perfect analogue amplification, Goldmund recommends the Goldmund Telos series of power amplifiers. The connection between the analogue sources and the preamplifier as well as between the preamplifier and the power amplifiers are also critical.
  • Page 6 CAUTION Should you need to return the MIMESIS REFERENCE to the factory or your local representative for warranty repair, please be aware that it must be repacked using the original packaging. This packaging has been designed to specifically safeguard your MIMESIS REFERENCE during transit.
  • Page 7 For detailed information regarding the acceptable range of main line voltage, please refer to the Technical Specifications section at the end of this manual. Should the nominal line voltage prevalent in your region fall outside this range, please reach out to your local Goldmund dealer for assistance.
  • Page 8 Connect the cabling from the power supply output “Power Supplies” to the preamplifier input point labeled “Power”. Warning! The next stage in setting up your MIMESIS REFERENCE is to connect your sources, power amplifiers and other peripheral devices. All devices should be disconnected from mains power until safe.
  • Page 9 The main POWER switch is located on the rear panel of the Goldmund MIMESIS REFERENCE power supply. In regular use, this switch should be left permanently ON and the circuits of the preamplifier activated or deactivated using the STANDBY ON/OFF.
  • Page 10: Input Selection

    The Goldmund MIMESIS REFERENCE is designed to capture, control, shape and nurture the fragile source inputs, supporting adjustment of volume and balance to deliver your desired output signal. The primary control functions supporting these processes are outlined below. STANDBY To activate the preamplifier (set to ON) put it into STANDBY ON mode by pressing the SET/PWR and the MUTE/PWR buttons simultaneously.

    Trial and error is therefore often necessary. GOLDMUND “MECHANICAL GROUNDING” In the MIMESIS REFERENCE preamplifier, Goldmund has implemented its renowned construction method to provide an optimized vibration evacuation path. User Manual – MIMESIS REFERENCE - Analogue Preamplifier - 15 -...
  • Page 16: Protection Circuit

    To get all the benefits of this improvement, the MIMESIS REFERENCE must be located on a very rigid support, directly coupled to the building. Avoid any decoupling material. If carpet decouples the preamplifier and ground, use pin-point supports to couple the furniture to the floor.
