The more you know about Dual, the more this turntable will surprise you.
This is the new Dual 515. There's one reason you'll want to know more about it. And one that will surprise you.
1. The design and engineering.
Vibrations from footsteps and acoustic feedback can muddy the sound from records, cause mistracking and even groove jumping. The sophisticated suspension system of the 515 solves this problem with typical Dual ingenuity.
The tonearm, drive system and platter and mat are isolated from the base by four independent shock absorbers-with damping qualities computer-designed to cope with all likely conditions in the typical home.
above: Four independent shock-absorbing elements, with computer-calculated
damping, isolate the tonearm, platter and drive system from the turntable
base, and thus from external shock and vibrations such as those caused by
footfalls or acoustic feedback. This system, combined with the new Dual platter
mat, achieves a higher level of isolation for the record during play.
You can easily hear the difference this entire system makes when you play a record on the 515. The bass will be tighter, the highs cleaner and missing details restored.
Now for the tonearm.
Dual's exclusive ULM (Ultra Low Mass) tonearm and cartridge system has only 7 grams total effective mass. That's less than half that of conventional tonearm and cartridge combinations. ULM assures accurate, stable tracking, especially on badly warped records. But low mass is only one aspect of Dual's tonearm design.
The four-point gyroscopic gimbal centers and balances the tonearm where it pivots. The straight-line tone arm tube is made of XM300 alloy for its extremely high rigidity and low resonance. Dual's system for setting track force-a tempered, flat-wound spring inside the pivot-maintains the tonearm's dynamic balance.
The belt-drive system is also pure Dual. The belt is precision-ground to within 1/200 mm. The high-torque motor and 12% pitch control are electronic. The illuminated strobe confirms exact speed.
2. The price.
This is the surprise: less than $135! (The 515 is semi-automatic; the fully automatic 530 is less than $150.) We think this will really surprise all those who've been willing to pay substantially more for West German design, engineering and precision manufacturing. Now you have all that, plus new and unprecedented Dual value.
