CR 2025 Battery

HEAT/PROPER VENTILATION/ADEQUATE SPACE

Position the unit away from all heat sources such as heater registers, stoves, kitchen appliances, or 

other heat producing components including preamplifiers, phono stages, or power amplifiers. 

Blocking or covering the slots and openings in the top and bottom of the unit can create ventilation 

problems and cause overheating.  In order to protect the component from overheating, never block 

these openings. Always allow at least four inches of clearance above the unit and two inches all 

around the unit for airflow.  NEVER place the unit on a cloth, padded cushion, pillow, or any other layer 

that can block the bottom ventilation holes. The owner should always provide proper spacing around 

this product by placing it on an open rack with adequate ventilation. Do not place the amplifier in an 

enclosed rack. Heat buildup will shorten the lifetime of the tubes and the internal components. 

ELECTRICAL CONSIDERATIONS

POWER SUPPLY

Operate the unit only from the power voltage indicated on the marking label on the back of the amplifier. 

Each unit is marked with the voltage it is set up for. This varies from country to country. In the United 

States, it is 110-120 volts.

POWER CABLES

Arrange power supply cables so that they do not cross any areas that have foot traffic or are restricted 

and can become pinched or bent. Any items placed over or against power cables must not restrict, 

gouge, or cut them. Never use ungrounded or improperly built power cables or multiple supply boxes/

strips!

GROUNDING AND POLARIZATION

As a safety feature your product is equipped with a Type B, Class 1 American standard NEMA 5-15 

plug. This plug will only fit into a properly designed power outlet. If you cannot insert the plug fully into 

the outlet, never try altering the plug. If the plug does not fit, you must contact a licensed electrician to 

update the obsolete outlet. NEVER defeat the grounding pin of the polarized plug.

You can purchase an electrical socket tester (3 wire receptacle tester) inexpensively from Home Depot 

or Lowe

s. It will indicate whether you have an open ground or reversed polarity.

REMOTE CONTROL

The Raven Audio Remote Control is used to adjust volume. When you press the upper 

button, you will see the volume control knob rotate clockwise. When you press the lower 

button, you will see the volume knob rotate counter clockwise and hear the volume 

decrease. Be careful when adjusting the volume not to turn the volume knob past the 10 

o’clock position if there is no music playing, it may come in too loudly. The remote control 

has screws on the back that can be removed to replace the battery. It uses one CR 2025 

battery.
