The core elements in more detail
The Motor
The motor is arguably the most important part of any turntable: it’s the only source of energy for the signal generated by the cartridge and fed out to the amplifier, so quality and accuracy is vital. The DG-1 motor system is derived from that developed for the flagship RG-1 Reference Motor Drive: it uses the most advanced motor drive, delivering the best possible performance. The motor itself is a low voltage 24-pole precision synchronous design, individually tuned for the lowest noise and with an offboard power supply. It’s controlled by a microprocessor PCB, addressable during manufacture to ensure accuracy and programmable for future upgrades. A copper and stainless steel cover provides shielding from both inward and outward interference.
The Platter assembly
Drive to the platter is via a precision machined aluminium alloy pulley on the motor and a bespoke silicone rubber drive belt, with electronic speed change for ease of use. The platter itself is also precision machined alloy, to which is bonded a PETG record interface mat and, on the underside, a cork/neoprene/nitrile disk bonded to control platter resonance.
The Bearing
The platter fits onto a highly polished stainless steel spindle, that rides in a main bearing housing on a super precision tungsten carbide ball. The complete main bearing assembly is longterm lubricated for longevity and ease of use. This avoids normal repeated recharging of the bearing lubricant that is essential to avoid premature wear and damage. Another example of the simplification of this turntable to optimise performance.
The Arm
The DG-1 arm is uniquely Vertere, and differs from established thinking in its use of a flat profile in place of the usual tube. Conventional arms use tubes for stiffness, but these can bring all kinds of problems with high Q resonances, and thus the need for critical damping – costly and complicated. The DG-1’s three- layer, non-resonant tonearm beam avoids these problems. In place of conventional tonearm cabling, a flexible PCB is sandwiched into the arm itself to carry signal from the cartridge to the output terminals. Completing the arm are a stainless steel counterweight and a tracking adjustment weight, giving a total solution that’s as simple and elegant as it is innovative. |
