Bellari VP549 Phono Preamp

You have an input that connects to your phonograph, and an output that plugs into your preamp or amplifier. Use the ground post to connect to your turntable's ground connection. AKA "subsonic filter" cuts very low frequencies (below 20 Hz). The purpose of a filter like this is to get rid of annoying frequencies that disrupt the turntable's sound quality. A good rumble/subsonic filter should be inaudible, meaning you cannot hear when it is on or off in the program material you are listening to. The VP549 has three settings: 120 pF, 220 pF, and 330 pF. Set the switch in the position you feel sounds best to you. The difference might be very slight, but it is there. Most cartridges come with a capacitance load recommendation in the spec sheet for the cartridge.. Specifications Weight: 2 lbs; .
