Module in order to drive or low-loss networks with strong magnetic circuit parts the latest sharp speakers, only slightly higher than the rated output values product catalog is not enough. In order to fully drive responsiveness to all signals for the speaker, must possess the ability to instantly supply current. In addition to the abolition of the current limiter in addition to minimizing the power transistor's emitter resistor (0.1W), and through the use of thicker material internal wiring and signaling the internal layout of the shortest, realized the great instantaneous current of 150A supply capacities.bTEservice manual download site
HDAM?SAbTEservice manual download site
Of the original Marantz unique high-speed voltage increase HDAM? can be used to increase commonality with the buffer amplifier the amplifier, but not professional current feedback amplifier module. Therefore, the HDAM? based on in-depth evolution, developed specifically for new current-feedback amplifier is the best. Not only can be used as buffer amplifiers, but can also be used for I/v converter module, is an important part of Marantz current feedback amplifiers. The voltage amplifier section 6 General operation the amplifier can not achieve high conversion speed.bTEservice manual download site
All balanced signal processingbTEservice manual download site
Amplifier circuit using a stable equilibrium structure. From input to output, under the same conditions to parallel to the positive and negative signal wiring. Transferred to the shortest possible distance to the input signal, power modules take the form of Transection of left and configure it. Shortest distance from the input terminal to the signal input to a voltage amplifier, a power buffer amplifier for power increases, direct output to the speaker terminals.bTEservice manual download site
Newly developed core-level 2-toroidal transformerbTEservice manual download site
New toroidal transformer is used, the transformers continue to be used on the most ideal sound quality improved toroidal transformer. Although the toroidal transformer is an ideal choice, but due to the power of environmentally sensitive and therefore easy to rattle when the condition does not improve. This newly developed transformer of centric parts overlapping in circular-core material, surrounded by barriers covered with wire, in order to ensure that under no condition would beep. Magnetic leakage around embedding used to suppress the horizontal direction silicon steel core-ring based on the enclosure to inhibit vertical magnetic leakage in aluminium housing. With low vibration and low magnetic leakage of the transformer with a higher sound quality, particularly to improve the s/n. And, as insulators to the transformer by aluminum blocks with equal distance between magnetic body chassis are securely fastened.
