Our most compact Reference Power Amplifier, the 9007 offers similar levels of power to the 9008A and 9011 Reference models—if not the ultimate in peak power—in a package that, while equally beautiful, is far less demanding of space.
Because let’s face it, in order for our to Radialstrahler loudspeakers to create the magical illusion of no speakers at all, for them to conjure Miles or Jimi or Lenny into your listening room, a powerful amplifier is not an option, it is an absolute must.
But power alone won’t get the job done. What MBL’s Radialstrahler speakers demand is an amplifier that can deliver huge levels of continuous and peak power, along with a refinement of sound that matches that of the Radialstrahlers themselves.
A fully balanced design, the handcrafted 9007 is simply a smaller version of our statement amplifiers. It shares the same basic technology, parts and circuitry, and can also be operated in either mono or stereo modes.
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
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.
The mbl 9007 power amplifier can be used both in STEREO and in MONO mode.
In STEREO mode the pre amp is connected to the power amp with two unbalanced cables.
In MONO mode the pre amp is connected to two power amps with balanced cables.
When placed in the context of a complete MBL system, one designed to operate as an entity, the 9007 will wow you with its ability to step aside and let the beauty and emotion of the music shine through. An MBL system isn’t like any other. It’s like being there.
