◆ trans•nova (TRANSconductance NOdal Voltage Amplifier)

The trans•

nova

(TRANS conductance NOdal Voltage Amplifier) is a patented circuit (U.S. Patent 4,467,288) that allows

the audio signal to pass through the amplifier at

low voltage

. Each amplifier channel utilizes its own “fully floating” power

supply and is configured to increase power gain. The increase in power gain allows the drive stage to operate at a lower

voltage. A low voltage drive stage is the same principle used in high quality preamplifiers to produce high linearity and wide

bandwidth.

◆ DIAMOND (Dynamically Invariant AMplification Optimized Nodal Drive)

DIAMOND

(Dynamically Invariant AMplificiation Optimized Nodal Drive - patent pending) is an important advance in circuit

design which reduces high frequency distortion. Amplifiers which utilize a large array of output MOSFETs cause a high

capacitive load on the driver stage. This load can make the high frequencies sound harsh. The DIAMOND circuit eliminates

high frequency distortion by allowing the driver to operate with 20dB or more of current headroom, whereas traditional drivers

have only 6dB of current headroom.

THE RESULT: Lower distortion and greater inherent stability.

◆ MEHSA (Maximum Efficiency Heat Sink Application)

The

MEHSA

(Maximum Efficiency Heat-Sink Application) is a proprietary process that yields up to 5 times better heat transfer

than traditional FET mounting techniques using the exact same components. A multi-layer insulated metal substrate

operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device

across the heat sink. This process combined with our DSM technology and MOSFET devices allow us to squeeze more watts

per cubic inch from every output device as well as provide consistent thermal stability.

THE RESULT: Optimized power output, enhanced thermal stability, and maximum component reliability.

The resulting design utilizes an output stage with a simpler gain structure and a shorter total signal path than conventional

high voltage (bi-polar) designs. The number of stages is reduced from five or more to three. The output stage is further refined

into a trans-impedance stage (current to voltage converter) to achieve a short loop (fast) negative feedback. The output stage

is driven cooperatively by a transconductance stage (voltage to current converter).

THE RESULT: Superior sound quality, greater efficiency and higher reliability.
