DG-1 Dynamic Groove

The DG-1 Dynamic Groove Record Player is designed for a less extreme Vertere customer: one who is driven by performance but needs almost Plug and Play setup.

Description

From the plinth to the arm and its bearings, everything has been redesigned and re-engineered, developing some of the basic principles of a record-playing system while completely rethinking others.

The result is an elegant turntable that looks like no other, but draws on the engineering of the reference models to deliver outstanding performance and ease of operation at a newly affordable price.

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.

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 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.

Many solutions have been sought over the years for precise bearings, but for the DG-1 Vertere has developed a very simple solution: twisted nylon threads (hundreds of 3 microns thick twined Nylon 6.6/6 strands) – one for movement in the horizontal plane, and two for the vertical axis. These threads have many advantages, not the least of which is simplicity: they exhibit none of the stiction – or initial resistance to movement – of conventional bearings, are super-light and noiseless, and the twist of the thread controls and damps the movement of the arm.

Like the tonearm, the DG-1 plinth is a sandwich construction, using non-resonant cast acrylic to form the main plinth and the sub-plinth for a clean and sophisticated look. This three-layer design incorporates the control button, the speed indicator and the user-selectable standby mood-lighting, as well as the silicon rubber isolation between the plinth and the platter assembly. The whole assembly sits on a steel chassis, chosen for optimal stability, housing the motor drive circuit and the motor all supported by three adjustable feet. The DG-1 comes complete with a non-resonant acrylic dust-cover, where its hinges are integrated into the plinth for a sleek and modern profile.
