Hot on the heels of the 2240, the 2245 features a beefier power supply and an additional 10 amps of current available at its terminals.  Be prepared for an overwhelming dynamic response and enough headroom to compell even more difficult loads to Galactron's eurhythmic living presence.

Amplifier designed with a solid-state technology with polarization in class AB. 

The feed structure has been made of toroidal transformer 320VApower supply

The total capacity of the filtering system is 90,000 UF, in order to provide for  

even the most challenging demands in current.

The high value of damping factor has been obtained with the use of

the two pairs of mosfet selected from about 20Ah per channel,  

for which the configuration has been gained by a low value of output

resistance and high availability of current,  

providing a way to remarkably control the articulation and the relative 

information content of the same spectrum with remarkable precision. 

The tone obtained comes out with a high degree of consistency across the entire sound spectrum, high lighting the great potential for analysis of micro- and macro-details of the musical content.  

Innovative new drivers in pure class"A" gives a great increased quality, control and 

harmonic richness. 

The 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. 

The preamplifier section and management inputs have been built with solid state  

Technology and the amplification 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.

The stadium management inputs have been divided into four sections of RCA line, 

allowing the end user to use multiple devices in connection and

manage them differently, thanks to the use of a switching system  

and remote volume control in steps.

In addition, the light signals the status of each line via the LED’s of various colors.

The MK 2245 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.
