UHC-MOS (Ultra High Current MOS) FETs capable of carrying large currents are used in a single push-pull operation. It uses a simple circuit. In the method of obtaining a large current by driving a large number of elements in parallel, a problem caused by the variation in the performance of the elements is solved, and the turbidity of the sound is solved. In order to achieve the expressive power of painting even the delicate expression of the musical sound, Denon has stuck to amplification with the smallest unit of elements, one pair. This unit uses the latest generation of UHC-MOS FETs, which are also used in the PMA-SX1. Compared with conventional products, the rated current is doubled from 30 A to 60 A and the instantaneous supply current from 120 A to 240 A. Rebuilding with even more leeway is achieved. In addition, a cascode bootstrap connection keeps the voltage across the UHC-MOS constant and increases temperature stability. The excellent acoustic characteristics of UHC-MOS are steadily brought out. Using a large aluminum extrusion material for the heat sink increases heat dissipation. By providing the power supply circuit with sufficient power supply capacity, it achieves high output of 120 W/8 ohms and 240 W/4 ohms. Even low-efficiency speakers can be driven with plenty of room. 【Clean and powerful power circuits】 Amplifier operation is like "magnifying copy" of the input signal to the current supplied by the power circuit. If the power supply current is dirty, the signal will be copied over that dirt. Also, if the power supply does not supply enough current, the copy will be cut off or distorted. In other words, accurate amplification is not possible. In this machine, the power supply unit has two stages: an output stage requiring large current and a voltage amplification stage requiring stability. Separated from the winding stage of the transformer. The rectifying capacitors include a high-capacity, high-quality electrolytic capacitor with a low-impedance electrode foil, and a High-quality capacitors with different frequency characteristics are combined to achieve high sound quality. The rectifier element is a Schottky barrier diode with low loss, low noise and high speed. It provides sufficient and clean current supply. 【Sand-Shaped Aluminum Cast Case-Enclosed Power Transformer】 The power transformer is both a source of amplifier power and a source of unwanted vibration and noise. As with the PMA-SX1, the sand-shaped aluminum casting case is filled with a special resin to eliminate vibration generated by the power transformer. Careful magnetic shielding also suppresses noise in the enclosure caused by leaking magnetic flux to provide a clean power supply. The trance, with its extra thick winding wound evenly and comfortably, produces a clear, powerful sound. Sand mold holders are also used to fix capacitors that are susceptible to vibration. The thorough vibration-friendly design ensures clear reproduction with no blurring. 【6-block chassis】 Phonoequalizer and input, volume control, voltage amplifier, power amplifier, power supply, It uses a six-block chassis with separate controls. A 1.6 mm-thick steel chassis protects the signal circuit from external vibration, It also eliminates the effects of interference between each circuit. 【Other functions and features】 CR Phonoequalizer for MC/MM Large analog volume Direct Mechanical Ground Construction Balanced input & external preamp input Carved brass gold-plated input/output terminal Recording output terminal Left/right volume balance adjustment function Auto Standby Mode (factory OFF) (Product specifications) ■Power amplifier section Rated power 120 W + 120 W (8 ohms, 20 Hz to 20 kHz, THD 0.1%) 240 W + 240 W (4 ohms, 1 kHz, THD 0.7%) Total Harmonic Distortion: 0.01% (Rated power at -3 dB), Load: 8 ohms, 1 kHz Output Terminal Speaker Load: 4 ~ 16 ohms Input sensitivity/input impedance EXT.PRE: 1.1 V/23 kohm Gain value: 29 dB ■Preamp section Recording output jack 150 mV Input sensitivity/input impedance PHONO (MM): 2.5 mV/47 kohm PHONO (MC): 200 microV/100 ohm (High), 200 microV/50 ohm (Low) CD, NETWORK, TUNER, AUX, RECORDER: 165 mV/25 kohm BALANCED: 165 mV/100 kΩ RIAA deviation PHONO (MM/MC): +/- 0.5 dB (20 Hz to 20 kHz) Maximum input PHONO (MM): 130 mV/1 kHz PHONO (MC): 10 mV/1 kHz ■Overall characteristics S/N ratio (IHF A network, 8 ohm load) PHONO (MM): 82 dB (Input terminal short circuit, input signal 5mV) PHONO (MC): 70 dB (Input terminal short circuit, input signal 0.5 mV) CD, NETWORK, TUNER, AUX, RECORDER: 108 dB (input terminal shorted) Frequency response 5 Hz to 100 kHz (0 to -3 dB) ■General Dimensions (W x H x D) 435 x 181 x 506 mm Mass 27.4 kg Power consumption: 380 W (according to the Electrical Appliances and Material Safety Act) Standby power 0.1 W/0.2 W (auto standby mode on/off) Accessories Easy start guide, instruction manual, remote control, 2 AAA batteries, power cordReturns ・We accept return items up to 60 days after the item has arrived.
