What are the Key Factors?
There are 2 main styles of turntable motor; Belt driven and Direct drive. Belt driven turntables use a belt to connect the motor and platter together, and while this has some benefits for vibration absorption its not ideal for DJs. The main reasons being that they wear down and snap, and provide an inconsistent start & stop time. This is where direct drive comes in. Direct drive turntables use an electo-magnetic motor that is keeps the turntable spinning at a more consistent speed and have far longer life spans than their belt driven counter parts. This makes them ideal for DJs and turntablists alike.
Torque is how powerful the motor is, the higher the torque = the faster the start / stop speed. It also helps to keep the platter spinning when back cueing and scratching. Some turntable will have a fixed torque, while others will allow you to customise it to your style.
WOW & Flutter
If you’ve heard a record where the pitch keeps changing or there’s some distortion, then chances are you’ve experienced WOW & flutter. WOW & Flutter is caused by variations in the platter speed with in turn affects the pitch of the playback. Most modern turntables will have a crystal oscillator to keep the motor in time (most common is Quartz) which greatly reduces the fluctuations in playback. Some of these turntables will also feature a ‘quartz lock’ function that disables the pitch control and locks motor to the crystal timing for the best playback performance.
RPM stands for revolutions per minute. There are 3 typical vinyl record speeds: 33¹⁄³, 45 and 78 RPM.
Most vinyl records you will come across are 33¹⁄³ RPM and is often referred to as a long-play (LP) style. 45 RPM is rarer these days and used more for ‘singles’, they also have a large centre whole and require a ’45 adapter’ to play. 78 RPM records are much rarer and are generally smaller in size (10″) compared to the 12″ size of a standard 12″ vinyl record.
There are two tone-arm shapes; ‘S’ and ‘straight’. Mostly this is aesthetics (providing your cartridge and needle are installed correctly). But the idea is that the straight tone arms are harder wearing and better suited to scratch DJ styles while an S-shape is better suited to playback. Another benefit of the straight arm is it takes up less area on the platter / vinyl giving you more room to manipulate the vinyl for back-cueing and scratching. But is always recommended to use the shape that feels more natural and comfortable.
These are internal pre-amplifiers that transform your turntables output from Phono into a line level. Great for connecting to modern technology that doesn’t support a Phono input. Some turntable will have these and will even give you the option to switch it on/off (like the RP-7000) depending on your set-up.
On-Board USB Interface
This cool little device allows you to digitally record your vinyl directly to your PC or MAC. Typically onboard interfaces will output up to 48kHz at 16-bit (CD quality) whicdh is great for transferring classic and limited pressing songs to an easier to play format.
