The entry-level 540P is a high quality Moving Magnet design featuring single-ended "Class A" gain stages and discrete transistors instead of the more common integrated circuits. This gives less cross-talk and interference across the signal path. The 540P employs an active RIAA equalization system. The rear panel benefits from gold plated input connectors to minimize signal path interference and reduce surface degradation. An external power supply comes as standard.Product FeaturesThis gives less cross-talk and interference across the signal path.The 540P employs an active RIAA equalization system.Technical DetailsBrand Name: CambridgeModel: 540PComponent Type: Phono preamplifierAudio Output Mode: StereoWeight: 1.8 pounds
