While the pitch control is intended for DJs audio classical music lovers often complain that records are mastered imperfectly. You can finely adjust the speed. Shown here is the arm lifts that allows the arm to float down on the record. The light on the left is to help you lower the arm properly. And you can see the quartz lock speed button.
The underside of the steel platter is coated to thick anti-vibration absorbing rubber. This helps reject vibrations caused by the music itself and prevent acoustic feedback. The stylus does not know if the vibrations come from the grooves of the record or externally.
Shown here is the S shaped tonearm to minimize tracking error. You can adjust the height of the tonearm to perfectly match the phono cartridge. Shown also is the anti-skating adjustment and arm lift. You loosen the callar to remove the headshell and cartridge
Here you see the lighted power switch which illuminates the strobe for perfect speed. You see this turntable will play old 78s too.
The adjustable anti-resonant feet help reduce acoustic feedback too. The Audio-technica ATLP140 is a hunk of a turntable. It weighs 23 pounds. It has 3 key upgrades from the ATLP120: heighth adjustable tonearm, thick anti-resonant platter and a real robust power supply, not a rinky dink plug in ac adaptor. No preamp and no A to D converter. You want to use the one built into your amp or receiver for better sound.
