Ovation High Fidelity’s new Model 1547 Phono EQ Amplifier accepts either moving coil (MC) or the more common moving magnet (MM) inputs and boosts and equalizes the signal from a turntable to the industry standard RIAA curve, after which it can be fed into a standard line preamplifier or integrated amplifier.
The MC front-end utilizes an ultra-low noise single ended JFET amplifier stage to deliver better than 75 dB S/N ratio (ref 500uV input ‘A’ Weighted), while the MM input uses a very low noise amplifier stage for superior performance, with signal to noise ratio’s approaching 80 dB (‘A’ Weighted). An all-active EQ topology delivers best in class overload capability of > 32 dB (MM ref 3 mV input) and > 40 dB (MC re 250 uV input). The result, say Ovation High Fidelity is a “remarkably smooth, quiet, phono stage that delivers the pristine, full-bodied analogue sound enjoyed by vinyl lovers”.
Switchable loading and gain, located on the unit’s rear panel, caters for input signals from 250 uV to 1.2 mV on MC and 1.2 mV through to 8mV on MM, while a built-in rumble filter attenuates any sub-sonic noise be that from an off-centre hole, record warp, or motor rumble. On MM inputs, switchable capacitive loading enables MM cartridge response to be optimised to the cartridge supplier recommendations. RIAA EQ conformance is to within +-0.2 dB (typical) over the audio frequency range,
Unlike many competing products, the Model 1547 power supply is built into the housing, reducing cabling and therefore minimizing hum and noise pick-up – reference 500mV out, ‘A’ weighted hum levels approach -90 dB (MM input) and better than -80 dB (MC input).
Designed, engineered and assembled in the UK, the Model 1547 retails for £975-00 and comes with a 5-year Warranty. Dealer enquiries welcome.
