| − | == Remarks ==
| |
| − | The 1249 has the same "Flywheel" belt drive with a sub-disc (ALU) attached to the axle and a turntable resting on it as the older 601 single player.
| |
| − | However, it has a weaker platter bearing due to the interchangeable axle.
| |
| − | Also, the zinc die-cast of the 601 has given way to the aluminium die-cast of the 1249.
| |
| − | The tonearm of the 1249 has been reworked compared to the 601 and has a very low bearing friction and a counter-oscillator in the counterweight, which allows a high scanning capability and safe scanning even of cartridges that actually require a tonearm with a lower effective mass for optimal operation.
| |
| − | * Like all pre-ULM arms ('''U'''ltra '''L'''ow '''M'''ass) from Dual, the arm of the 1249 belongs to the lighter medium weight arms with an effective mass of ~ 12gr. including subheadshell (TK).
| |
| − | * The motor is an 8-pole AC synchronous motor without servo electronics (SM840).
| |
| − | The speed fine adjustment is done mechanically by spreading a slotted drive roller and is very sensitive.
| |
| − | * Drive and tone arm are qualitatively superior to current Dual models (CS-455,505-4).
| |
| − | * The factory-installed pickup was chosen with consideration of the change function and is clearly below the capabilities of the device.
| |
| − | * When used as a single player, it is essential to install a higher quality cartridge.
| |
| − | * Even MCs are no problem as long as they are not explicitly designed for heavy arms.
| |
| − | * A few years ago still a bargain, he now achieves quite handsome prices in the second-hand market.

| + | Der 1249 besitzt denselben Antrieb wie der 601 Einzelspieler. |

| + | Die Kraft wird per geschliffenem Flachriemen auf den Metallsubteller |
| | + | übertragen auf welchem der Plattenteller aufliegt. Die gesamte Dreh- |
| | + | masse beträgt 2,1 kG. |
| | + | Der Tonarm des 1249 ist jedoch gegenüber dem 601 überarbetet worden |
| | + | und verfügt über eine sehr geringe Lagerreibung was eine hohe |
| | + | Abtastfähigkeit des Tonabnehmers ermöglicht. |
| | + | Wie alle Vor-ULM-Arme ('''U'''ltra '''L'''ow '''M'''ass) von Dual gehört der Arm des 1249 zu den |
| | + | mittelschweren Armen mit einer effektiven Masse von ~ 12gr.. |
| | + | Antrieb und Tonarm sind aktuellen Dual-Modellen (CS-455,505-4) |
| | + | qualitativ überlegen. |
