Azur 651P Moving Magnet (MM) and Moving Coil (MC) Phono Pre-amplifier
• Phono pre-amplifier with moving magnet (MM) and moving coil (MC) input stages
• Discrete transistors for the all-important input stages instead of the more common
integrated circuits
• Single-ended ‘Class A’ gain stage with audiophile passive RIAA equalisation
• Multi-parallel capacitors to achieve exceptional RIAA accuracy of only
0.3dB up to 50kHz
• Defeatable subsonic filter to eliminate very low frequency ‘rumble’, caused by vinyl
imperfections
• Eco-friendly <1W Standby power consumption
• Acoustically damped full metal chassis with thick brushed aluminium front panel
• Available in brushed black and silver finishes
