MC2 Audio shipping E series flagship

MC² Audio is now shipping the flagship of its E series, the E100 amplifier. The E100 is the manufacturer’s most powerful four-channel amp and also the first four-channel proprietary Class-D switchmode amplifier to be developed by MC².

The E100 can reportedly deliver 2,800W into 4-ohms with all channels driven from a 2U, 11.8kg chassis. Included in the design are a Hybrid Dual Loop Feedback system (HDLF), an Active Energy Steering Circuit (AESC), custom drive circuitry and magnetic components to ensure high power, low impedance operation.

The E100 has been designed to run 2-ohm loads, thus giving power in excess of 3,500W from each of the four channels. This gives the amplifier the ability to run bass applications and allows bridging of a pair of channels down to 4-ohms. As such, bridging a pair of channels via the rear panel switches turns the E100 into a bass amplifier offering 7,400W at 4-ohms and over 5,300W into 8-ohms.

Also featured is a new Power Reduction Circuit (PRC), which acts as a power control limiter on each channel and the main power supply. The function of these circuits is to distribute the available capacity of the main power supply across the four channels. Each channel has a timed current limit and an immediate current limit, allowing each channel to deliver maximum power within a defined ‘window’. Should the demand of all four channels exceed the maximum capacity of the main power supply (or mains feed) then timed limits or immediate power limits are applied to all channels by the main power supply.

The E100 is equipped with protection systems to cope with the usual fault conditions such as a shorted load, DC on outputs and Thermal Overload. Thermal limiting is also included, reducing the output power of the amplifier gradually to compensate for very high internal temperatures rather than shutting the amplifier down into protection mode.

The front panel display incorporates indication of the channel’s Power Reduction Circuit, Protection, Bridge and Channel link modes. Each channel’s limiter also features a five-bar LED graph. These represent the amplifier’s relative output to the selected limiter threshold, and are reportedly accurate to within 0.25dB.

The feature set is completed with optional gain settings of 26, 32 and 36dB on each channel – user selectable by an internal jumper setting - rear panel Channel Link switches, Neutrik XLR female connector inputs and Neutrik Speakon 4-pole outputs and a captive mains cable. An optional EQ/X-over Board is available.
