Know before you buy
Variable MC loading allows you to fine-tune the impedance between 50 and 550 ohms to perfectly match your specific moving coil cartridge. This ensures the cartridge performs at its optimal frequency response, resulting in a more accurate and balanced sound.
Yes, the JC 3+ is designed to accommodate both types. It provides 48 dB of gain for MM cartridges and 64 dB of gain for MC cartridges, ensuring proper signal levels for a wide range of turntable setups.
The dual-mono design uses completely isolated enclosures and separate power supply components for each channel. This physical separation minimizes crosstalk and interference, which results in a lower noise floor and a much wider, more precise soundstage.
Yes, it features professional-grade Neutrik XLR balanced outputs. If your amplifier supports balanced inputs, using them is recommended as they provide superior noise rejection, especially over longer cable runs.
The Mono switch is designed for playing back vintage or modern mono LPs. By summing the channels, it reduces surface noise and eliminates the phase errors that can occur when playing mono records through a stereo cartridge.
The integrated AC line conditioner filters out common electrical noise and interference from your home's power grid. This helps maintain a clean signal path, allowing the preamp to resolve finer musical details without the background hum often associated with power line pollution.
