M-6000
1,200 W/1 OHM MONOPHONIC
POWER AMPLIFIER
1,200 W/1 Ohm monophonic power amplifier with power MOS-FET devices — Two separate but
completely identical power amplifier circuits are mounted on the left and right sides of the chassis and
driven in parallel. The result is a power amplifier with extremely low output impedance and ideal speaker
drive characteristics. Latest instrumentation amplifier technology in dual configuration enables fully
balanced signal paths. Double MCS+ and current feedback topology in amplifier circuits ensure
impeccable sound quality, outstanding S/N ratio, and minimal distortion. Massive power supply with large
high-efficiency 900 VA toroidal transformer and plenty of filtering capacity. Output stage employs power
MOS-FETs in a 16-parallel push-pull configuration that realizes constant-voltage speaker drive. Printed
circuit boards with fluoropolymer glass fabric substrate featuring low dielectric constant and minimum
loss, and gold-plating of major signal-carrying parts further enhance sonic purity. Bridged operation
allows use of two M-6000 units as a monophonic amplifier with even more power, capable of delivering
2,400 watts into 2 ohms.

P-7100
1,000 W/1 Ohm
STEREO POWER AMPLIFIER
Inheriting the design policy of the models M-8000 and P-7000, this stereo power amplifier is capable of
delivering an amazing 1000 watts per channel into ultra-low impedance loads of one ohm. The amplifier
circuitry employs the instrumentation amplifier principle with fully balanced signal transmission. Circuit
boards with fluoropolymer glass fabric substrate featuring extremely low dielectric constant and low loss
assure pure signal transmission. Further improved MCS+ topology and current feedback design result in
even better S/N ratio, distortion, and other performance parameters for outstanding electrical characteristics
as well as sound quality. Each channel features 11 wideband power transistors arranged in a parallel push-
pull configuration. Together with the large 1.5 kVA toroidal power transformer, this assures linear power
progression down to extremely low 1-ohm loads. Bridged mode allows upgrading to a monophonic amplifier
with 2000 watts into 2 ohms.

P-6100
700 W/1 Ohm
STEREO POWER AMPLIFIER
The high-end stereo power amplifier P-6100 is a stereo version of the Class AB Monophonic Power
Amplifier M-6000 using power MOS-FETs in the output stage. Benefiting from the outstanding design
technology of its predecessor, the P-6100 features instrumentation amplifier topology for fully balanced
signal paths, as well as a further refined MCS+ circuit and the current feedback principle to minimize noise.
Printed circuit boards made from glass fluorocarbon resin with low dielectric constant and low loss, as well
as specially selected top-grade materials and parts are used throughout. The output stage employs an 8-
parallel push-pull arrangement of high-power MOS-FET devices renowned for their great sound and utter
reliability. Massive heat sinks on both sides of the chassis achieve efficient dissipation of thermal energy.
Together with the high-efficiency toroidal transformer housed in an aluminum enclosure with heat dissipation
fins and the two large 56,000 µF filtering capacitors, the power supply allows the amplifier to deliver an
amazing 700 watts of power per channel into an ultra-low impedance load of 1 ohm (music signals). Using
the P-6100 in bridged mode creates a monophonic amplifier with even more impressive power capability,
rated for 1400 watts into 2 ohms (music signals).
