Main Features

The only equipment among the class　with a non-feed back type amplifying circuit composed of only discrete parts.
Aiming for an expansion of music expression, an all-step non-feedback circuit which performs a current-amplifying-operation suiting to the semiconductor is newly developed and adopted. Excellent expressions of uplifting feeling, dynamics, and shading-feeling which are only produced by the non-feedback circuit can be enjoyed.
Only discrete parts are adopted in the circuit, which could be called the only equipment among this class. As a result, all of “rich gradationa expression of sound, uplifting feeling, high S/N ratio, and fantastic space representation” are simultaneously achieved at high level, equivalent to an upper class equipment which was difficult on phono amplifiers of this class.
Solid chassis structure and Dual monaural pattern The chassis base and the top cover using 1.6 mm thick steel plate used with this equipment are treated with copper plate, and furthermore, they are finished with painting to restrain vibration. By synergistic effect with the front panel using 8 mm thick aluminum plate, this equipment achieved reduction of magnetic distortion and securing the strength of rigidity.
Builds the dual monaural layout of the same pattern of the left and right, and actualizes a uniformity of the left and right channels at a high level. By adopting the large R-core transformer and supplying power without any common power impedance due to left/right individual powers, a channel separation of 90dB or more (20Hz to 20kHz) is accomplished.
Introduction of parts for high sound quality.
For RIAA impedance devices and main parts of the signal line that greatly influence the sound quality, the parts for high sound quality parts such as metal film resistor and high quality film capacitor which are acknowledged are adopted. The power supply circuit is designed to decrease the noise greatly by adopting fast recovery diodes of considerably higher rating and low noise zener diodes, in order to prevent the increase of recovery time in the large current range.

Names and Functions

Front Panel

1. POWER Switch
   Turns the power on or off. If the switch is pressed, the power is turned on.

2. POWER Indicator
   The power indicator lights up blue when the circuit condition is stabilized.
   Right after the power switch is turned on or the FUNCTION switch is switched to MM or MC, it lights up red and a sound is not outputted until the circuit condition becomes stabilized.

3. FUNCTION Changeover Switch
   Set the FUNCTION switch to the MC position when an MC cartridge is used; set it to the MM position for an MM cartridge or for an MC cartridge with a high output voltage of 1.5mV or more.
   In order to prevent a noise generation, the equipment is designed so that the sound is not outputted right after switching the FUNCTION switch to MC or MM.
   (② POWER Indicator: red) The sound is outputted after the ② POWER indicator is changed to blue.
   Rear Panel

4. Phono Amplifier Input Terminal
   Connect the signal wires of your analogue disc player with L and R respectively.

5.  Phono Amplifier Output Terminal
   Connect the EA-220 OUTPUT terminals to the input terminals for line level (150 to 250mV) such as AUX terminals of the pre-amplifier.

• Do not connect them to the phono input terminals of a pre-amplifier having a built-in phono amplifier. Due to the excessive input, the sound will be distorted. 6. Earth Terminal (GND Terminal)
  Connect the earth cable of the analogue disc player with the GND terminal.

  7. Power Inlet Terminal
     Connect the attached AC power cable to the power inlet terminal.

Connection

Trouble Shooting Guide

In case the equipment does not operate properly, check out the followings.

Firmly insert the AC power cable into the AC inlet terminal of this equipment.
The sound does not come out.| The signal wires are not plugged in completely.| Insert the signal wires completely.
The type of cartridge used and the FUNCTION changing switch do not match.| Match the FUNCTION changing switch (MM/MC) to the cartridge (MM/MC) to be used.
Sound is distorted.| The OUTPUT terminals of this equipment are connected to the input terminal of the phono of pre-amplifier.| Connect to the input terminal for line level (such as AUX) of pre-amplifier.
I lum sound comes out.| Connection of signal wire is not enough.
The earth cable from the analogue disc player is not connected.
A power supply transformer or motor of other electric device is placed nearby.| Plug in the signal wires completely.
Connect the earth cable completely.
Place this equipment apart from a power supply transformer or the motor of another electric device.
Sound does not come out immediately after switching on the power supply.| Sound does not come out until the condition of internal circuit is stabilized.| Wait until the power indicator is changed to blue.
The power is turned off and a hollow sound comes out after a while.| This is the sound due to a short circuit to be driven in this equipment.| The sound is normal.
