M9 Amplifier

The M9 is a minimalist integrated amplifier design dedicated to reproducing music with the utmost accuracy and clarity. With the M9, audio legend Mark Levinson, founder of Daniel Hertz, has again redefined excellence in audio amplifcation by utilizing new technology to provide the most advanced performance and features – this time, at a price point that puts the best within reach of more people.

Under the guidance of Mark Levinson, Class D audio amplification has matured and become the successor to previous “state of the art” audio amplifier technology hailing from the 1960’s. New Daniel Hertz technology, previously unseen in the world of audio, delivers astonishing performance and sonic quality with a high level of integration – allowing the a ordable, lightweight, and compact M9 to outperform many large, heavy, and expensive “high end” power amplifiers. While weighing only 5kg (10.8 lb), the M9 delivers 200 Watts Per Channel (WPC) into 8 Ohms, and 400 WPC into 4 Ohms. With serious power, low output impedance, high output current, and pure natural sound, the M9 is an ideal amplifier for virtually all quality music speakers, including large power hungry models. Also noted, the M9 is a highly efficient design, utilizing most of the AC power it consumes to create sonic output, instead of useless and annoying heat.

The M9 has three analog and three digital inputs, including: digital coaxial, USB, and Bluetooth wireless. Now, music played from a smartphone or tablet sounds virtually identical to the studio recorder used to make the recording. Each of the three RCA analog inputs features a 1 megOhms input impedance, providing essentially unloaded operation for the selected source device. To eliminate analog input switching, sonic degradation, crosstalk, and reliability issues, analog input is converted to digital signal by way of dedicated (per input) high performance analog to digital converters (ADC). The stereo analog line-level record output can be connected to auxiliary audio systems and recording interfaces.

The Input source Status LED displays different colors to assist the user with understanding which audio source is engaged while the M9 is in operating mode. Likewise, the Power Status LED indicator provides mode and signal information through color associations.

Similar to the Input source selection knob, the Volume control knob is also a manual rotary knob. However, the Volume control knob is a digital control with in nite rotation – meaning, no stop at minimum or maximum gain. Listeners more familiar with analog volume controls will be surprised with the in nite rotation of the knob, but pleased with its functionality and many advantages including: fine resolution, wide dynamic range, transparent sound quality, and high reliability.

The Headphone jack is a 1/4” female headphone connector. A dress plug is provided to prevent the 1/4” jack from being visually obtrusive while headphones are not in use. The dress plug is removed by using the thumb and first finger to pull the dress plug away from the face of the amplifier. When headphones are connected to the M9 1/4” jack, the speaker outputs are disabled. Headphones with a 3.5mm, or 1/8”, mini-plug require a female mini-plug to 1/4” male adapter for use with the M9. For operation anywhere in the world, the internal switching mode power supply (SMPS) operates from 90VAC to 250VAC without user adjustment.
