PHAEDRUS DC 3002-II Resolve Linear Power Supply
Chapter 1 – The Phædrus Audio equipment power supplies
- All Phædrus Audio equipment require a high-quality, external power-supplies. The hi-fi/archiving Groove Sleuth preamplifiers (of all types); the ADAMANTINE preamplifier; and the FRANCINSTIEN WARP product all require 12V DC power.
- The external power supplies are manufactured with the highest audio-quality in mind and ensure that the power provided to the preamplifier is very low noise and very low impedance. All PSUs connect to the preamplifiers unit via a cable with screw-lock connectors.
There are two options of PSU to power this equipment:
- The basic PSU is an external, high-quality, universal power-supply unit (GS-PSU). These are supplied with the unit.
- The external power supply may be upgraded to the GS-RESOLVE-PSU.
RESOLVE Power Supply
- Housed in an identical chassis to the preamplifiers, the RESOLVE power supply is a linear supply and of the very highest audio quality (see Chapter 3 – Specification).
- Because the RESOLVE power supply is linear, it is NOT UNIVERSAL, so different options must be selected for mains power/power-grid voltages with nominal values 230V AC or 110V AC.
Chapter 2 – Connecting the GS-RESOLVE-PSU and the preamplifier
- The PSU and preamplifier should be connected BEFORE mains is applied to the PSU unit. It is not dangerous or harmful to the equipment, but it is better never to disconnect the preamplifier and PSU whilst this link is live.
- Phædrus Audio equipment is designed to be compatible with European Eco-Consumption directives. The unit and its power supply are intended to remain energised all the time.
- The design is thereby compatible with the best audio practice of leaving the unit energised all the time whilst respecting the environment, and your electricity bill!
Voltage setting & Fuse replacement
- The RESOLVE PSU is a linear type supply and is internally set to be 110V (±10%) AC or 230V (±10%) AC. The correct voltage type must be used according to the mains supply available. If in doubt, consult Phaedrus Audio. The RESOLVE power supply should be fitted with a 5 × 20mm, 2 Amp, SLOW BLOW glass fuse.
