ALAUDA
MB-3

DESCRIPTION

 

Class D mono power amplifier based on the HYPEX NC1200 board. Thanks to this technology the amplifier is ultra-linear, has levels of noise and distortion that are almost non-existent (even lower than those typical of the highest quality A or B classes) and can also handle the most difficult loads thanks to a 'ultra-low output impedance.

 

Musical features:

  • crystalline and deep bass: this is not the usual boom but a depth of definition that makes the presentation unique and touching. The amplifier has always the maximum control of the speakers thanks to the high damping factor;

  • clarity and detail: the hyper detail of this amplifier is not artificial since all the instruments, although superbly isolated, are also coherently blended together;

  • tonal fidelity: it does not add or remove the smallest fragment of musical information; well-recorded music is incredibly transparent and dynamic and seems to be drawn against the backdrop of the cosmic-black void;

  • sound image: wide and deep, the images are accurately blocked with surgical authority.

 

The PSU is the Hypex SMPS1200A700 module. Balanced (XLR) and unbalanced (RCA) input selectable via switch. Internal wiring made with high quality cables.

The ALAUDA MB3 is made in two versions, depending on the buffer stage used. This affects some technical parameters (such as input impedance and gain) but above all the sound signature of the amplifier.

ALAUDA DM-1200 : the power stage has the input buffer developed by Hypex on the NC1200 module: LM4562 op-amp and HxR voltage regulators. The input impedance is 98Kohm.
ALAUDA DM-1200 NCX : the amplifier is implemented with the Rouge NCX2 for the management of the buffer stage. The NCX2, by default, uses the TI OPA1612,  the best IC's on the market for transparency and sound clarity (without adding color) whose DC power is supplied by the NC1200 module via the HxR voltage regulators. The NCX2, via a DIP8 socket, can also work with discrete op-amps like SPARCOS SS3602 ot SIL 994 Enh-Ticha. The user can always choose and select at any time which configuration prefer for his setup (OPA1612 or the one installed on DIP8).The input impedance is 47Kohm.
