Phasemation EA-500 Separate Type Phono Equalizer Amplifier B-grade goods UsedDescriptionRobust chassis structure consisting of two independent L/R complete monoblock enclosuresThe robust chassis structure consists of a 12mm-thick machined aluminum front panel, a 2mm-thick copper-plated steel chassis base, and a 2mm-thick aluminum cover to ensure rigidity and reduce magnetic distortion. The sound reproduction, supported by the left and right equalizer sections and power supply, provides an overwhelming sense of presence, clear stage reproduction, high resolution, and high S/N for music enjoyment. Newly designed V-I/I-V conversion type all-stage symmetrical non feedback amplifier circuit using all discrete componentsNegative feedback amplifiers, which are the mainstream of modern amplifiers, constantly compare the input and output signals of both semiconductors and vacuum tubes, and amplify the difference (correction signal) as the input signal, thus enabling low-cost, high-precision amplification. However, there is a time delay between the input and output signals that cannot be resolved in principle, and this is one of the major causes of TIM distortion and other problems that make negative feedback amplifiers unsatisfactory in terms of sound quality. At PhaseMation, all amplifiers, both semiconductor and tube, are configured as non-feedback amplifiers. Since non-feedback amplifiers do not have the correction operation of negative feedback amplifiers, they require high precision and technology in their component parts and circuits. As a result, 100% of the information from the sound source (record) can be reproduced, and in terms of sound quality, it is possible to reproduce music with musicality, with excellent expression of musical dynamism, dynamics, shading, etc. In this unit, carefully selected discrete elements are converted to current by a newly designed V-I/I-V conversion type all-stage symmetrical non-reduction amplifier, and the input signal is converted back to voltage after equalization processing, and then output via a buffer that is connected in pairs. Various input switching functionsThe MC1 and MC2 input terminals are equipped with balanced input terminals using XLR connectors in addition to RCA terminals. 2.For MC input, a newly designed step-up transformer with a special split-winding structure for MC balanced transmission is built in to support MC balanced transmission. Enhanced Functions1. a CR2-stage non-reduction type Low Cut Filter is installed. This filter plays warped vinyl records with no sound quality degradation and prevents speaker (woofer) shaking. 2.2. 3 types of playback curve switching switches. In addition to the conventional RIAA characteristics for STEREO, Mono1 (for use with DECCA labels, etc.) and Mono2 (for use with Columbia labels, etc.) are provided as monaural-only characteristics for the equalizer. This enables higher fidelity reproduction of both DECCA and Columbia labels. V. Adoption of high-quality sound componentsIn the signal system1: For RIAA elements, which have a high influence on the sound quality of phono amplifiers, we use reputable high sound quality components such as 1% grade metal film resistors with generous rated capacitance and microphone capacitors that use silver microphone plates as dielectrics.2: The signal system uses Elnas Silmic sound quality compatible electrolytic capacitors and 1% grade metal film resistors.The power supply circuit uses1: SiC diodes manufactured by ROHM, which are known for their low switching noise and high sound quality, are used.2: The rectifying capacitor uses a top-quality audio-grade large-capacity electrolytic capacitor with gold-plated terminals using low-resistance electrode foil manufactured by Nichicon Corporation. Decoupling capacitors are made of ELNAs CERAFINE.3: The use of low-noise Zener diodes, coupled with a shunt regulator that eliminates the feedback circuit, constitutes a high-speed, extremely low-noise power circuit.4: Power transformers with R-core and low leakage flux are used exclusively for the + and - power supplies, and bridge rectification is performed for each to eliminate the adverse effects of common ground impedance. categorySeparate type Phono equalizer amplifier conditionClass BLch: one side front right corner is hit.Rch: No noticeable scratches ACCESSORYOriginal box, instruction manual, power cable x2, ground wire product specificationsType V-I/I-V conversion type all-stage symmetrical non-return equalizer amplifierInput style MM MCInput sensitivity 2.5mV 0.18mVApplicable cartridge output impedance 47k? or less 1.5 to 40?Gain 38dB 61dBInput converted S/N ratio -120dBV -140dBVRated output voltage 200mV (1kHz)Rear curve deviation ±0.5dB (20 to 20kHz)Power consumption 12W (100VAC 50 to 60Hz)Dimensions 210 (W) x 103 (H) x 355 (D)Weight 5.5kg/single channel ShippingShipping by FedEx or EMS.International Buyers - Please Note:Import duties, taxes, and charges are not included in the item price or shipping cost.
