MK 2240

Amplifier designed with solid state technology and AB class polarization.

Solid state amplifier MK 2240 has a feed structure made with a toroidal transformer 220 VA power supply and a total filtering system of 40,000 UF in order to provide even the most challenging amount of current.

Power and Quality

Thanks to the use of the 2 pairs of mosfet, selected from about 20 Ah per channel, MK 2240 amp has an high value of damping factor.
Configuration has been gained by low output resistance and high availability of current, giving way to articulation remarkable level of control and the relative information content of the same spectrum.

Tone obtained comes out in a high degree of consistency across the entire spectrum, highlighting the great potential for the analysis of musical content’s micro and macro details.

Final stage is characterized by a significantly increasing trend in terms of the current demand of the dynamic transient.
In fact, it is able to almost double its power to halve the resistive value of the load applied without any limitation in current, obviously linked to the maximum available power from the feeding system itself.

 

 

Other Benefits

The preamplifier section and management inputs have been built with solid state technology the amplification’s stage of the low level has been obtained with components focused on maintaining low noise: excellent Series Integrated Burr-Brown with values of slow-rate high.

Stadium management inputs have been divided into 4 sections of RCA line, allowing to use multiple devices in connection and manage them differently, thanks to switching system and remote volume control in steps. In addition, light signals the status of each line via the LED’s of various colors.

MK 2240 has a rear switch with the task of feeding the whole machine to ensure optimum working temperature, before activating the button of the remote control, the amplifier achieves its best performance after at least 30 minutes of power. Before that time music can be played, but not at optimal quality.

About Amp Placement

It’s important to ensure good ventilation over the entire surface of the amplifier, because the internal temperature heat sink forming part of the power stage could reach over 60° C. In case it’s increased further, thermal protection would come into operation by releasing the entire power system to protect amplifier and any speakers which might be connected to it.
