For the first time in Unity Audio's history they have introduced a DSP Mini-Rock version to replace the standard. This high performance 24bit/96k Burr Brown converter design offers a huge amount of DSP control for the user with precise 1/10th dB level control on the input channel and output channels , mute, phase, delay and 8 bands of fully parametric EQ including various filter types, limiter protection. Plenty of factory and user presets are included such as full 3 way crossover integration for the Unity Audio Avalanche sub-woofer.
The intuitive GUI is Mac and PC compatible over sealed air-tight Neutrik Ethernet connector. The DSP also has an additional output channel presented to the Mini-Rocks rear panel on a balanced XLR connector to feed the Unity Audio Avalanche active sub-woofer for example, along with the balanced XLR input connector.
The cabinet is a sealed pattern like all the models in the Unity Audio range so as to reproduce low frequencies with superior transient response and without any phase/timing anomalies associated with other designs. The Mini-Rock is also the first monitor in the range with the exception of the Avalanche sub-woofer that uses a split dual-chamber cabinet with Aperiodic Vent. This provides all the benefits of a sealed cabinet such as zero port noise and snug fast accurate bass reproduction. It also significantly rises the bass response available from a smaller cabinet design. The Mini-Rock shares the same 50kHz folded ribbon tweeter that is used in the larger Rock and Boulder models.
The JET tweeter
It was developed to perfection on the basis of the famous Air Motion Transformer by loudspeaker pioneer Dr. Oskar Heil. Its operating way consist of concertinaed-foil membrane, driven by a strong magnet system of neodymium rods. This motor drives the air considerably faster than the pistonic motion of a conventional driver, with gains in higher sensitivity and extraordinary dynamics. Due to many additional design changes, including special patented gluing and surface processes, improved new neodymium magnet system, even higher efficiency, higher sound pressure levels and frequency response up to 50 kHz was achieved.
With a fold width of only 0.84 mm, the JET guarantees repeated accuracy and unchanging quality even with high production capacity, gluing and handling are now executed by two SCARA robots. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring extreme precision, the manual dexterity of skilled technicians is irreplaceable.
A new crystal membrane woofer measuring 150mm ( 5¾" ) has been selected. The crystal-shaped inverse aluminium dome is joined to a paper cone in a special gluing process to result in the desired sandwich construction. The crystal cone aluminium-foil stamping stiffens the aluminium dome, diminishing resonances and minimising coloration, while improving power handling and dynamics. The voice coil design of the woofer results in an expanded frequency range, and driver surround allows for longer cone excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.
