Balanced Music Concept (B.M.C.) Audio introduced the high-end AMP CS2 integrated stereo amplifier with a built-in power amp upgrade option. The AMP CS2 can change from operating as an integrated amplifier with B.M.C.’s exclusive Load Effect Free (LEF) technology into a stereo power amplifier with LEF by simply connecting it to a B.M.C. digital-to-analog converter (DAC).
The AMP CS2 features a full package of B.M.C.’s unique and exclusive technologies, including LEF amplification, Current Injection (CI), and Discrete Intelligent Gain Management (DIGM). Contributing to the exceptional sound are a short, pure signal path, and the absence of distortion. Instead of compensating for distortion as other amps do through a negative feedback loop, the AMP CS2 simply avoids it, believing that it’s better to avoid distortion from the start than to try to correct it later.
The amplifier outputs 2 channels of 200 Watts into 8 Ohms, and 2 channels of 360 Watts into 4 Ohms. A fully regulated power supply with a large 2kW toroidal transformer, and energy storage by specially designed balanced current capacitors, provide the muscle behind the music even as the amp, itself, runs cool and quietly. In addition, an innovative electronic stabilization circuit filters voltage ripples and other disturbances out of the supply voltage, ensuring exceptional tranquility and dynamic stability.
Three Technologies
The AMP CS2 includes three technologies developed by and exclusive to B.M.C.:
- Load Effect Free (LEF) Technology handles a speaker’s current demand separately from the voltage demand. This helps the amplifier achieve high output and high-quality reproduction. It provides a top-level signal without voltage amplification, and increases efficiency. The result is a level of musical complexity that brings to life delicate details, rock-shaking power, high dynamics, sonic vitality, and accurate imaging.
- Current Injection (CI) Technology processes the input current from a signal source through a special XLR-CI input and the amplifier’s circuitry until it attains the desired output voltage for the loudspeakers, increasing the purity of the amplified signal and the immediacy of its musical reproduction.
- Digital Intelligent Gain Management (DIGM) is a volume and amplification control system that recalibrates gain without dividing and downgrading the input signal. It enables users to adjust left/right output balances in 66 1-decibel increments. It also avoids unnecessary attenuation of the input signal and excessive amplification, eliminates the need for a preamp circuit, and allows a DAC to directly connect to the amplifier. Less amplification means less distortion and noise, which leads to a more natural musical quality
The AMP CS2 is housed in a sturdy aerospace-grade aluminum chassis using the finest components available. Large Power and Volume buttons and an easily read Power Meter enhance the front panel. An aluminum remote control is included to operate the AMP CS2. Rear-panel connections include 2 pairs of balanced XLR-CI inputs, 3 pairs of unbalanced RCA inputs, 2 pairs of speaker outputs, an optical input and output for stereo operation, and an AC power connection.
Price and Availililty
The B.M.C. Audio AMP CS2 Power Amplifier is available now from authorized B.M.C. Audio dealers for $8,390.00 (U.S. MSRP).
