Features a high sound quality, high-performance MDS++ D/A converter. The USB port allows connection to a computer via USB cable, for reproduction of high-resolution music library data with superior sound quality. MM Features a high-performance, high-gain phono equalizer for playback of analog records with outstanding sound quality. ● MC/MM switching is possible on the front panel of the E-470. ● Internal DIP switches control MC input impedance and subsonic filter on/off. MC Gain: 40 dB Input impedance: 47 kilohms Gain: 66 dB Input impedance: 30/100/300 ohms (selectable) ● COAXIAL: For 75-ohm coaxial cable Supported sampling frequency range: 32 kHz to 192 kHz, 24 bit ● OPTICAL: For optical fiber cable Supported sampling frequency range: 32 kHz to 96 kHz, 24 bit ● USB: For USB cable (Type B connector) Supported sampling frequency range: 32 kHz to 192 kHz, 24 bit DAC-40 connection example Computer DAC-40 Digital component Optical fiber cable (Up to 96 kHz/24 bit) USB cable Coaxial digital cable (Up to 192 kHz/24 bit) Type B connector ( Up to 192 kHz/24 bit ( ＊For playback of material on a computer via the USB port, it is necessary to install software from the supplied USB Utility CD-ROM. (Not required with an Apple Macintosh computer.) Option Boards ● Two slots allowing easy insertion of option boards are provided on the rear panel. ● Option boards can be used to implement high-quality reproduction of a digital music signal supplied directly to the amplifier, or high-quality reproduction of analog records. ● It is also possible to install two identical boards. ● Revolutionary AAVA volume control ● Output stage with triple parallel push-pull power MOS-FETs produces quality power: 180 watts x 2 into 8 ohms ● Instrumentation amplifier principle for power amplifier input stage allows fully balanced signal transmission, complemented by MCS+ topology and current feedback amplification circuitry ● Logic-control relays for shortest signal paths ● Strong power supply with massive high-efficiency transformer and large filtering capacitors ● POWER IN button allows separate use of preamplifier and power amplifier sections ● Numeric indication of volume level ●Rated Continuous Average Output Power (both channels operating simultaneously, 20 - 20,000 Hz) 260 W/ch 4-ohm load 180 W/ch 8-ohm load ●Total Harmonic Distortion (both channels operating simultaneously, 20 - 20,000 Hz) 0.05% 4 to 16 ohm load ●Intermodulation Distortion 0.01% ●Frequency Characteristics HIGH LEVEL INPUT At rated continuous average output: 20 - 20,000 Hz 0, -0.5 dB POWER IN At rated continuous average output: 20 - 20,000 Hz +0, -0.2 dB At 1 watt output: 3 - 150,000 Hz +0, -3.0 dB ● Damping Factor 500 (with 8-ohm load, 50 Hz) ●Input Sensitivity, Input Impedance ● Output Voltage, Output Impedance PRE OUTPUT 1.51 V 50-ohm (at rated continuous average output) ●Gain HIGH LEVEL INPUT → PRE OUTPUT: 18 dB POWER IN → OUTPUT： 28 dB ●Tone Controls Turnover frequency and adjustment range BASS: 300 Hz ±10 dB（50 Hz） TREBLE: 3 kHz ±10 dB（20 kHz） ● Loudness Compensation ＋6 dB（100 Hz） ●Attenuator －20 dB ●S/N Ratio, Input-converted Noise ● Power Meters Logarithmic peak level indication, shown in dB and % ●Load Impedance 4 - 16 ohms ●Stereo Headphones Suitable impedance: 8 ohms or higher ●Power Requirements 120 V/230 V AC, 50/60 Hz (Voltage as indicated on rear panel) ●Power Consumption 92 watts idle 420 watts in accordance with IEC 60065 611 watts for rated output into 8 ohms ● Maximum Dimensions Width 465 mm ( 18.31”) Height 181 mm ( 7.13”) Depth 428 mm ( 16.85”) ●
