SAFETY PRECAUTIONS
CAUTION
RISK OF ELECTRIC SHOCK DO NOT OPEN
CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

* For proper heat dispersal, do not install this unit in a confined space,
such as a bookcase or similar enclosure.
· More than 0.1 m is recommended. · Do not place any other equipment on this unit.
NOTE ON USE
Avoid high temperatures. Allow for sufficient heat dispersion when installed in a rack. Handle the power cord carefully. Hold the plug when unplugging the cord. Keep the unit free from moisture, water, and dust. Unplug the power cord when not using the unit for long periods of time. Do not obstruct the ventilation holes. Do not let foreign objects into the unit.

Main Features
The only equipment among the classwith 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 gradational 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
POWER Switch Turns the power on or off. If the switch is pressed, the power is turned on.
POWER Indicator
FUNCTION Changeover Switch
Rear Panel
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.
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. ( POWER Indicator: red) The sound is outputted after the POWER indicator is changed to blue.
