Semi-Automatic Belt-Drive Turntable System
with AC synchronous motor and integrated tonearm (flat or tubular)
If you wish to use more than one phono pickup cartridge in the NAD 5120 turntable, you can purchase extra plug-in tonearms.
On each arm you can set balance, VTF and DVA (dynamic vibration absorber) frequency and damping.
Then you may quickly swap cartridges by unplugging one arm and plugging in another, with no readjustment needed (except perhaps for anti-skating and cueing height).
On the 5120 the counterweight is not mounted rigidly to the tonearm but rather suspended on a spring, forming a compliant assembly that is free to vibrate.
When correctly tuned its vibration matches and cancels the fundamental arm/cartridge resonance.

The NAD 5120 exhibited some lower midrange colouration although this was not too serious. Stereo images were stable, while the bass was satisfactory, possessing a fairly tuneful quality, better than usual for the price - £99 HiFi Choice 1984
A number of running improvements have given this player a range and tautness denied it's lazier sounding antecedents - £90 HiFi Choice 1992
