Every model ever built, what changed between them, and what it costs today. A hi-fi deck that disco and hip-hop hijacked, killed by its own durability in 2010, resurrected in 2016.

03Index of models

  1. 01MK1The original. A hi-fi deck that disco and radio DJs hijacked, the accident that started everything.
  2. 02MK2The legend. Quartz lock, the pitch slider, 31 years of production; the deck that built hip-hop and house.
  3. 03MK3Japan-only refinement: the first official all-black 1200, damped with Technics' non-resonance compound.
  4. 04LTDPiano-black and gold-plated: 5,000 units celebrating two million 1200s sold.
  5. 05MK4The audiophile detour: 78 rpm, detachable cables, upgraded tonearm; and almost never seen outside Japan.
  6. 06MK3DThe 'D' is for de-detented: the click at 0% pitch removed, a reset button added.
  7. 07M3DThe MK3D for the rest of the world, with a recessed power switch DJs couldn't kill mid-set.
  8. 08MK5The scratch-era workhorse: doubled anti-skate, white LED target light, last of the analog pitch.
  9. 09M5GThe 30th-anniversary hot rod: first digital pitch, ±16% range, blue LEDs. The turntablist favorite.
  10. 10GLDThree million sold, in black gloss and gold; 3,000 units on an M5G heart.
  11. 11MK6The final classic: quiet refinements, plus a 1,200-unit 35th-anniversary edition with a gold record.
  12. 12GAEThe resurrection: 1,200 numbered units for the brand's 50th, gone in about 30 minutes.
  13. 13GThe flagship: coreless twin-rotor motor, four-layer cabinet, 18 kg of no-compromise engineering.
  14. 14GRGrand Class for the rest of us: the G's ideas, 7 kg lighter and half the price.
  15. 15MK7The DJ deck returns: coreless motor, 78 rpm, reverse play; the first new DJ 1200 in nine years.
  16. 161210GAE55 years of Technics in black: 1,210 numbered units, with a strobe you can switch off.
  17. 17MK7RThe b-boy special: MK7 in Red Bull BC One colors, gold tonearm, red headshell.
  18. 18M7L50 years of the 1200: 12,000 units, seven colors, gold tonearms.
  19. 19GR2The current Grand Class: ΔΣ-Drive motor control and flagship-derived silent power at $2,199.
