GENERAL PRECAUTIONS & SAFETY NOTES

1.VACUUM TUBES BECOME HOT ENOUGH TO CAUSE SERIOUS BURNS. NEVER
TOUCH A TUBE WHEN THE UNIT IS ON. IT MAY TAKE SEVERAL MINUTES FOR
THE TUBES TO COOL DOWN AFTER THE UNIT IS SWITCHED OFF. INSTALL
THIS AMPLIFIER IN SUCH A WAY THAT PEOPLE, PETS, AND FLAMMABLE
MATERIALS CAN NOT COME INTO CONTACT WITH THE AMPLIFIER.

2.DO NOT EXPOSE CHASSIS TO MOISTURE. DO NOT PLUG INTO AN AC SOURCE
UNTIL ALL CONNECTIONS ARE COMPLETED.

3.Complete all signal (interconnect and speaker cable) connections before connecting the AC
cord to the wall outlet and turning the unit on. Similarly, always turn the amplifier off and
remove the AC power cord before detaching cabling. Failure to observe this sequence can
result in damage to the amplifier, speakers or associated components.

4.For protection of your speakers and power amplifier, source components should be switched
on before the power amplifier. Similarly, turn the power amplifier off before switching off
the source components.

5.THESE UNITS CONTAIN NO USER SERVICEABLE PARTS. DO NOT REMOVE THE
BOTTOM COVER. LETHAL VOLTAGES ARE PRESENT WITHIN THE CHASSIS. DO
NOT OPERATE THE UNITS IF THEY ARE WET.

6.This amplifier is moderately heavy. Please exercise caution in lifting the unit, and take care
to install it securely in a sturdy, well designed stand so that it will not fall or tip over (this
could cause serious, possibly fatal injury).

INSTALLATION

Physical requirements:

1)Provide Adequate Ventilation-Allow at least three inches of free air space above and two
inches to either side of amplifier

2)Do not place the amplifier in a completely enclosed cabinet. If equipment cabinet has a solid
front door, a “boxer” fan will be necessary to ensure proper airflow.

3)Do not stack other components (or any objects which could impede proper ventilation) on
top of the amplifier.

4)Do not operate the amplifer on carpet, or on any other surface that might restrict airflow.

5)The amplifier chassis will become very warm during normal use.

6)The amplifier must be installed in a secure, sturdy, properly built (and ventilated) stand,
cabinet or enclosure. The Standard Musicbloc 160 is heavy, and could inflict serious injury
or property damage if it falls, or if the stand upon which it is place tips over. This concern
is particularly important in households with small children who might try to climb furniture.
In addition, care must be taken to prevent people, pets, and flammable materials from
coming into contact with the VERY HOT vacuum tubes.
