ACCUPHASE E306 integrated amplifier with current feedback amplification circuit

Description: Product descriptionThe integrated amplifier which adopted the current feedback amplification circuit as a power amplifier part.The current feedback type amplifier circuit which returns an output signal in the form of a current is adopted as an amplifier circuit.The power supply section is equipped with a large power transformer with a large power capacity of approximately 500VA and a large capacity filter capacitor of 22,000μFx2.The line amplifier is composed of discrete parts, and is basically Accuphase's unique differential pure complementary push-pull input, and the output stage is finished with a single-ended push-pull type emitter follower. .Considering the characteristics of each cartridge of MC type and MM type, an equalizer amplifier equipped with a dedicated input circuit is adopted.A logic relay control method is used to prevent signal deterioration due to switching of input selectors, etc., and to configure the shortest and straightest signal path.The relay used is a sealed type for use in the communications industry, and the contacts are gold-plated and crossbar twin type, achieving low contact resistance and high durability.Two balanced input systems are provided, allowing balanced transmission.The volume control uses a high quality volume control and a small motor with a clutch to ensure smooth operation.The included remote control allows you to adjust the volume using a motor and control the input selector using a logic circuit.It is equipped with a selector switch and input/output terminals so that the preamplifier section and power amplifier section can be used independently.Equipped with a large peak power meter to monitor output power.The meter is logarithmically compressed, so you can check a wide dynamic range at once.It features large speaker terminals that can accommodate thick speaker cables.You can also insert a banana plug into this terminal.●Main specificationsModel Integrated stereo integrated amplifierRated continuous average output(Both channels operate simultaneously, 20Hz to 20kHz) 4Ω load: 140W/ch6Ω load: 120W/ch8Ω load: 100W/chTotal harmonic distortion rate (both channels operating simultaneously) 0.04% (4-16Ω load)IM distortion rate 0.01%Frequency characteristics(At rated continuous average output) Main/High Level Input: 20Hz to 20000Hz +0 -0.2dBLow Level Input:20Hz~20000Hz +0.2 -0.5dBDamping factor 120 (8Ω load, 50Hz)Disk maximum input(1kHz, distortion rate 0.005%) MM input: 250mVrms (Rec Out)MC input: 7.0mVrms (Rec Out)Input sensitivity/input impedanceInput sensitivity impedanceEIA at rated output (at 1W output)AD Input(MC): 0.11mV 0.01mV 100ΩAD Input(MM): 3.9mV 0.39mV 47kΩHigh Level Input: 113mV 11.3mV 20kΩBalanced Input: 113mV 11.3mV 40kΩMain Amp Input: 1.11V 112mV 20kΩOutput voltage/output impedance(At rated continuous average output) Pre Output:1.11V/50ΩTape Rec Output: 110mV/200Ω (from AD)Gain Main Input → Output:28dBHigh Level Input → Pre Output:20dBAD Input(MM) → Tape Rec Output:29dBAD Input(MC) → Tape Rec Output:60dBS/N, input conversion noiseAD Input(MC):Input short/A-correction EIA S/NS/N input conversion noise at rated inputMain Input: 124dB -121dBV 102dBHigh Level Input: 110dB -128dBV 83dBBalanced Input: 90dB -108dBV 82dBAD Input(MM): 85dB -132dBV 80dB70dB -146dBV 78dBLoudness compensator +6dB(200Hz, Volume-30dB)Subsonic filter 25Hz, -12dB/octPower meter Logarithmically compressed peak level displayDirect reading of output with dB scale and 8Ω loadLoad impedance 4~16ΩStereo headphones Compatible impedance: 4Ω to 100ΩPower supply AC100V, 50Hz/60HzPower consumption No input: 50WElectrical Appliances and Materials Control Law: 290WAt 8Ω load rated output: 390WExternal dimensions Width 475x Height 170x Depth 418mmWeight 20.2kg★The condition of the product is that it is used and has some scratches and dirt due to daily use.*Both the box and the product have a cigarette smell. note that.
