Symetrica is a 3 section ‘balanced’ or ‘symmetrical’ output power supply for high end domestic audio system use. It features a single mains supply input via a Neutrik 32amp Powercon locking connection, with a very low electrical impedance power cable supplied also using a Furutech 1363G (gold plated alpha pure copper) mains plug (UK).
This is a balanced power circuit which would apply to the USA. In the UK, the overall voltage is 240 volts and each power line carries 120 volts as opposed to 60 volts. Note how the reactive elements, the unwanted interference is cancelled out within the transformer.
Connectivity:
It is intended for the Symetrica Balanced Power Supply to be in circuit between the wall outlet and ALL audio devices within the system. The rear outlet sockets are numbered 1-10 which correspond to the following, depending on configuration requested at time of ordering:
Configuration A: Sockets 1 and 2 are fed by 1 x 300va balanced transformer - used to connect all digital equipment.
Sockets 3 and 4 are fed by the 2nd 300va balanced transformer - used to connect analogue source components, including the phono amplifier.
Sockets 5-10 are fed by the 1.5 - 2Kva balanced output transformer- used to connect the main gain stages, i.e., power amplifiers/s, pre-amplifiers and sub-woofers, powered loudspeakers, integrated amplifiers, etc.
Configuration B: Sockets 1, 2 and 3 are fed by 1 x 300va balanced transformer, and - used to connect all digital equipment.
Sockets 4, 5 and 6 are fed by the 2nd 300va balanced transformer - used to connect analogue source components including the phono amplifier.
Sockets 7-10 are fed by the 1.5 - 2Kva balanced output transformer - used to connect the main gain stages, i.e., power amplifiers/s, pre-amplifiers, subwoofers, powered loudspeakers, integrated amplifiers, etc.
Other custom configuration are available at the time of ordering. Please contact Z-Axis Audio for more details.
Features:
• Solid State Relay controlled On – Off main switch
• Primary input fuse 12 amp slow blow 32 x 6.35mm Eaton Bussman non resonant ceramic fuse.
• Inrush current limiting device. (MOV)
• Substantial DC filter section; features 16,500uf Vishay anti parallel capacitors (33K uf
each) and 35amp parallel bypass/overload Vishay bridge rectifier.
• Incoming Voltage display, switchable to indicate voltage output of the secondary stages.
• 3 custom specified and built isolating balanced output transformers to provide the following:
• 1 x 300Va circuit transformer for all digital equipment feeding 2-3 of the output sockets. Maximum current of 1.1amps (at 240v).
• 1 x 300Va circuit transformer for all analogue source equipment, i.e., Phono amplifier, tuner, turntable etc, feeding 2-3 of the output sockets. Maximum current of 1.1 amps (at 240v).
• 1 x 1.5 or 2Kva circuit transformer for all gain (amplifier) sections, i.e. power amplifiers, pre-amplifiers, phono stages*, powered loudspeakers, subwoofers etc. Maximum current 6.8 amps for the 1.5Kva or 8.8 amps for the 2Kva. (at 240v).
• Optional 2.5Kva or 3Kva main transformer (requires a deeper casework to accommodate this) for all gain stages, as per above.
• Phono amplifiers will benefit being fed from the 2nd 300va (sockets 3&4 or 4,5&6 depending on configuration specified at point of order).
• 3 x Current output display’s in red, one for each output section / transformer circuit.
• Voltage and current displays are able to be switched off via a high quality top mounted pushbutton switch.
• Output fuse status display LED’s in green indicate full function of all live pins of the output sockets. These indicators remain on when the voltage and current meters are switched to off.
• All internal circuit boards are made from either 4mm Tufnol or 2mm Tufnol for the LED fuse status display circuit, which is point to point wired.
• 10 x Furutech gold plated UK 3 pin outlet sockets, both socket’s live pin’s are fused with either 6 amp or 3 amp Eaton Bussman 32mm x 6.35 slow blow non resonant fuses depending on usage. These sockets are by far the best available with excellent physical grip of the mains plug.
• Solid copper low impedance earth bus bar connecting all earth points to the single entry point.
• All internal wiring from high quality pure copper silver plated stranded and Teflon insulated wire.
• All high pressure cold weld (crimp) construction using copper connections.
• Non magnetic casework from Valchromat and anodised aluminium.
• 4mm thick Aluminium laser cut rear panel for strength.
• Anodised Aluminium side fins for heat dissipation.
• Optional tinted acrylic top cover panel.
• 6mm Dark grey glass front faceplate.
• Dimensions; 530mm x 380mm x 170mm.
• Weight: 29kg
• Idle current usage >100mA.
• Heat dissipation – Low.
