are always fully connected, never "idled". This means that all secondary windings are always connected
to your loudspeakers, regardless of which output switch position you use (4 ohms or 8 ohms or 8 ohms
or 16 ohms, depending on the factory configuration you have selected). The result is that there is
neither a loss of transformer output efficiency, nor the introduction into the output signal of distortion
from parasitic oscillations of the secondary windings.
• Large Nickel/FeSi Core Output Transformers. As with our other models, Allnic uses very large output
transformers (114 mm) with nickel, mixed with FeSi, cores. This provides for higher inductance with
fewer windings than other designs can provide and results in the great benefit of an extremely wide
range of output frequencies.
• "Soft-start" Circuitry. Allnic uses soft start circuitry that, after sufficient warm-up only, provides the
high voltage supply to the plate of each tube. This protective design results in prolonged tube life and
fewer and less frequent issues with tube performance.
• Analogue Power Tube Current Monitors. In order to provide constant current (bias) monitoring for the
power tubes, Allnic uses an analogue current meter that is switchable to provide extremely accurate
monitoring of each PX25/300B/KT150 tubes. The meters make it exceptionally easy to see the status of
each tube at any time and to respond immediately to any variation in bias by use of the bias control
knob for the relevant tube. The meters offer a simple, unambiguous indication of each tube's status
compared to conventional LED bias monitors.
• Beautiful 20KHz square wave response. See Figures 1-3.

• As are all Allnic Audio products, the M-2500s are fully RoHS (EU Reduction of Hazardous
Substances regulation) compliant in construction and materials.
WHAT'S IN THE BOX?
Please check that each shipping box contains the following:
• One (1) Allnic M-2500 monoblock power amplifier. NOTE: the M-2500s are mirror imaged.
Each amp should be the mirror image of the other, with the rectifier tubes on the right side on
one and on the left side on the other.
• One (1) 15 amp IEC type power cord
One (1) Owner's Manual is also provided.
