The M 063 H1 is a pure playback machine and provides a pure high-end solution. As with the M 063 HX, the tape heads are directly connected to the XLR connectors, so the machine, similar to high-quality record players, serves as a pure drive and can be combined with various external playback amplifiers. There is also the possibility here to install another playback head, so that audio tapes with different track widths can be optimally reproduced.+ Options and Accessories

In order to meet a broad range of applications, the M 063 H1 chassis has been developed for professional applications and consists of high-strength aluminium. In addition, the wearing surfaces of the base platter are finely milled on both sides, ensuring that the angles and height of the mechanical elements of the tape transport are precise and lasting. The head block and audio heads are so precisely machined that there is no need for a time-consuming and inexact adjustment of the tape heads. The reel motors, capstan motor, power supply and audio unit components are so positioned as to keep the signal flows short, while failure-critical components are spatially separated from each other. This enables substantial measures to electromagnetically shield the components – particularly the motors and tape heads – to be avoided from the outset. All components and circuit boards are equipped with high-quality plug-in connectors on both sides. Longer cables and signal lines are grouped in a sealed cable harness with magnetic shielding. This allows servicing of all components to be performed with the minimum of delay, without having to change the position of adjacent cables or components.
The processor-based drive control prevents any kind of looping and tape deformation. The braking process from the spooling operation thus ensues completely electrically incorporating the sensitive tape tension sensors. You can select between two tachometer-controlled spooling speeds plus optional archive winding function with increased counterbalancing. For this purpose, extremely torque-invariable motors have been developed with state-of-the-art power electronics and direct drive. Even at high load, these fast-reacting servomotors generate hardly any waste heat, and operate virtually silently while developing an extremely high and uniform torque with their axial magnetic field. Two highly precise force sensors on the guide rollers monitor the tape tension and set the current for the reel motors without any delay. This enables both an extremely uniform tape-head contact and an extremely low slippage at the pressure roller, combined with low pressure strength.
The capstan drive thus possesses outstanding acceleration and deceleration values and can be in standby mode. For a smooth start that is gentle on the tape, first the pressure roller is engaged, then the motor accelerated – using precisely calculated ramp control – and stabilised without overshooting. This occurs in less than 0.5 seconds – even at a speed of 38 cm/s, and then the audio channels are activated. The speed control of the capstan motor is realised by means of the phase lock loop (PLL) method, a process with decades of proven performance behind it. Here a so-called phase comparator synchronises the frequency of the capstan shaft tachometer generator (in the microsecond range) with an externally supplied reference value. In contrast to the well-tried PLL regulation, the M 063 capstan motor, however, operates with a digital loop filter and process-controlled regulator. Only in this way was it possible to realise an extremely precise and fast-reacting direct drive with a very low wow & flutter.
The M 063 H1 audio head is directly connected to the XLR bushes provided for balanced signal transmission in the connecting terminal. This machine is therefore a pure drive with no integrated audio electronics. This radically new approach in the construction of analogue tape recorders thus offers all the possibilities that have always been a global standard in vinyl record players. The complete separation of drive and playback amplifier offered not only provides the ideal foundation for optimal audio specifications. In the future, it will not only be lovers of vinyl who appreciate the individual, optimal assembly of all sound-relevant components. Furthermore, the option of equipping the device with two audio heads is also available on request: this allows, say, tapes recorded in various track widths to be played back on a machine with no loss of quality.
