This true analog power amplifier is built only with discrete components. No integrated circuit, nor microprocessors are involved in this design. Our engineers have created a fully balanced design for mono operation. Though, there is a possibility to drive this amp in Stereo too, thus offering incredible flexibility, especially in High End home theater setups. In short, it is a technical masterpiece manufactured in the service of music.
The circuitry technology concepts developed by MBL, such as the “DPP” (Direct Push Pull)is combined here with a unique new circuit board design with ultra-short signal paths. In addition, special low-induction components in the passive environment make it possible to exploit the full bandwidth of this amplifier.
• Multi-layer PCB quality FR4 with heavy CU planes in the output section
• galvanic gilding to protect the copper against pollution
• ultra short signal paths
• extreme high peak pulse power up to 1.900 W (MONO)
• balanced XLR and RCA input
• Layout in “ground-plane” and “eye-of-an-needle” techniques
• Low-induction MPC resistors and MHz-type RSH capacitors
• Super-fast ring-emitter transistors in X-crossed array
• DPP circuit (Direct Push Pull)
• IGC technology (Isolated Gain Cell)
• Regulated power supply for the Class-A drive electronics
• Custom MBL-built binding posts made of pure copper
• No output relays
• 132.000 uF custom built power capacitor bank
• Pure copper internal wiring
• DC servo coupling
• Flat frequency response to beyond 350 kHz
• Outstanding mechanical structure
This fully balanced differential amplifier employs a custom built toroidal transformer for the power stage and 1 custom-built, fully-shielded toroidal transformer for the driver stage. The power transformer is mounted on an aluminium metal shield and encased in epoxy for ultra-effective damping. The output stage and the driver stage employ separate supplies to fully isolate the output stage from the input stage. |
