MARK LEVINSON PRODUCTS CODE WHICH DRIVES

Five prestigious brands - Arcam, JBL Synthesis, Lexicon, Mark Levinson and Revel - come together to offer the most advanced high-performance audio systems.Very desirable ML-9 from the early days of Mark Levinson.Mark Levinson No.360s DAC - Quad Multibit 24-Bit Burr-Brown PCM1704s. With precision control and processing including a. Twelve analog, phono, and digital inputs travel through the Mark Levinson proprietary Pure Path discrete, direct-coupled, fully balanced, dual-monaural signal path for breathtaking purity and performance. The Mark Levinson 526 is the definitive preamplifier for todayвЂ™s music lover.

Mark Levinson Products Code Which Drives

The power stages are protected by an energy limiting circuit which monitors power dissipation versus time. The inverter converts from balanced to ground (differential) to unbalanced to ground while maintaining push-pull operation.Consists of a complimentary emitter follower, driving a second complimentary emitter follower.Consists of four parallel complimentary push-pull emitter followersThe on/off switch doubles as an electromagnetic circuit breaker to protect the amplifier from excessive current. Four 520 в™џ capacitors are used for added decoupling of the pre-driver stage.Consists of a differential amplifier with a cascode which drives a second differential amplifier with a cascode and a current inverter. The ML-9 has been designed to drive complex loads with complete stability.The ML-9 is a high quality Class ABв‚‚ stereophonic amplifier designed to provide virtually the same sonic performance as the ML-3 in a component of about half the power, weight, size and price.Consists of a 1,2 kVA toroidal transformer, a 30A bridge rectifer, and two 36,000 в™џ capacitors. The power supply of the ML-9 consists of a 1,2 kVA toroidal transformer and a pair of 36 milli-Farad capacitors, allowing for energy storage in excess of 230 Joules.The damping factor can be adjusted by means of a three-position toggle switch on each channel to meet the requirements of virtually all presently available loudspeakers.

Sensing circuit that monitors the output of the amplifier. The loudspeaker is protected by a D.C. This circuit offers excellent protection without effecting the sonic quality.

Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. For the reason the ML-9 is equipped with selectable damping capability.Rated Power:В 100 watts continuous sine-wave power pre channel into 8 О© with both channels driven from 20 Hz - 20 kHz with no more than ,2% T.H.D.Frequency Response:В (-3 dB) 3 Hz, 44 kHz (ultra sonic filter is a modified bessel alignment)Power Consumption:В 400 W at rated output into 8 О©, 50 Hz - 400 Hz (100 W at idle)Overall Dimensions (W x H x D):В 482 x 216 xВ 339 mm (19' xВ 8-1/2' x 13-3/8')Mark Levinson ML-9 - Original Sales BrochureThe SkyFi Testing Process for Solid State Amplifiers:We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. We have determined that certain loudspeaker characteristics can be effected by varying the damping factor of the amplifier. Several other techniques have been employed to protect the ML-9 from external sources of damage.Loudspeakers, like all electrical devices, are not perfect.

The amplifier then remains powered on to 'burn in' on our test bench for a few hours to make sure there are no heat related issues. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. If there is an issue, it will usually be noticeable at this point.

Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.Please click here for detailed specifics regarding our specialized packing process that separates us from the rest. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material.
