Turntable and Cartridge Buying Guide
Feel like dusting off your old vinyl records and turntable? Here are a few things to know to get you crankin’ those tunes again.
Does your receiver have a "phono" input?
First you need to check your receiver to see if it has a “phono” input. A phono input looks like any other RCA type of input but the input is specifically designed for turntables. This is a high impedance input and will not work with any other type of device. Most RCA inputs on your receiver are known as “low impedance” and designed for analog sources like CD players, tape cassette players, or VCRs.
If your receiver does not have a phono input all is not lost. You can purchase a separate phono stage pre-amp that will allow you to use an input on your receiver to connect the turntable properly. If your turntable is a newer model it may already have a phono stage pre-amp built in, you can check the owner’s manual for the turntable to find out if this is the case. If the turntable does have the pre-amp built in there will be a switch this gives you the ability to turn the pre-amp on or off.
Phono Cartridge Mounting
Once you have your turntable connected the next thing to check is the turntable cartridge. Most turntables use one of two types of cartridges; a “P” mount style and a “.5 inch Standard Mount” style. The “P” mount has four terminals or pins on the rear of the cartridge, and inserts into the end of the tone arm. This type of cartridge is secured by a single horizontal screw. The half inch (also known as standard) mount also has four pins at the rear of the cartridge. On this style you’ll see four wire leads coming out of the headshell that connect to the pins. The headshell is the part that attaches to the tonearm and holds the .5 inch cartridge in place via two vertical screws.
Cartridges do not last forever and will periodically need to be replaced, so if you have not replaced your cartridge in a few years it may be time to do so. This is because cartridges lose their sensitivity over time, and though the cartridge still works it is not giving you the best performance your turntable can produce.
Cartridges vary in price, how much you spend on the cartridge can depend on how much you spent on the turntable. It does not benefit you to put a very expensive cartridge on an inexpensive turntable, a moderately price cartridge will work fine. If you have a higher end turntable then you would benefit to invest in a more expensive cartridge to ensure you are getting the best quality performance from your turntable.
Moving Magnet vs. Moving Coil Phono Cartridges
Once you determine the mounting style of your turntable cartridge, you may decide to replace it or upgrade. If you decide your phono cartridge needs to be replaced, there are two major varities to choose from: Moving magnet and moving coil. Both varieties have advantages and disadvantages.
Moving magnet cartridges (MM) are perhaps the most common cartridge on the market. With this design, a magnet is permanently attached to the end of the cantilever and is positioned between two sets of fixed coils. This configuration creates a very tiny electromagnetic generator. As the stylus tracks the groove of the record, the movement travels up the cantilever, moves the magnet between the coils, and thus generates a current. These types of cartridges are simpler mechanically, tend to be less expensive and only require a single phono preamp to get the proper sound output. MM cartridges are a bit heavier than other designs, however, which causes them to exert more tracking pressure on the record and may cause increased wear on the vinyl. In addition, some listeners find this increased pressure can negatively influence the sonic quality of the vinyl.
Moving coil cartridges (MC) have a design that is a bit more complicated. This variety has coils attached to the cantilever while the magnet is permanently fixed nearby. As the stylus tracks the groove of the record, the movement travels up the cantilever, moves the coils by the magnet and creates the current. This design is preferred by some because the cartridge is lighter, causes less wear on the vinyl, and is widely considered the most sonically accurate. This complicated design is a bit harder to manufacture and subsequently costs more. In addition, the lightweight coil has an extremely low output and may require an additional amplifier stage. They are also susceptible to hum and noise.
Record Care
Now that your turntable is ready to go, you'll want to be sure your records are in good shape. A top-of-the-line phono cartridge will make little difference if your records are dirty or dusty. Be sure to invest in some vinyl cleaning products to optimize the sound quality and minimize hissing or crackling.
