TECHNICAL DESIGN FEATURES

◆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.

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.

◆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.
