Balanced Phono Stage Preamplifier The new Electrocompaniet ECP 2 Phono Preamplifier is designed according to guidelines seen in the phono preamplifier from Dynamic Precision. It incorporates state-of-the-art instrumentation operational amplifiers and like other Electrocompaniet products, it uses the highest quality of discrete components through the whole signal path, all DC coupled of course. The ECP 2 accommodates any imaginable pick-up and cable combination, thanks to it’s highly configurable input stage. User can select best suiting capacitive and resistive load configuration regarding to the pick-up cartridge used as source, no matter whether it is of an MM or MC type. Overall gain is also adjustable in 5 dB steps to accommodate different output levels from different pick-ups. The ECP 2 follows strictly the standard RIAA playback equalization curve, having also steep low frequency roll-off to filter out unwanted signals originating for example from playing back warped records.
