Important 1

Warnings

• Do not place a container with liquid or small metal objects on top of this unit. Liquid or metal objects inside
this unit are a fire and electrical shock hazard.
• Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock may result.
• Connect this unit’s power cord only to an AC outlet of the type stated in this Owner’s Manual or as marked on
the unit. Failure to do so is a fire and electrical shock hazard.
• Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a fire and electrical shock
hazard.
• Do not place heavy objects, including this unit, on top of the power cord. A damaged power cord is a fire and
electrical shock hazard. In particular, be careful not to place heavy objects on a power cord covered by a carpet.
• If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit,
turn it off immediately. Remove the power cord from the AC outlet. Consult your dealer for repair. Using the
unit in this condition is a fire and electrical shock hazard.
• Should this unit be dropped or the cabinet be damaged, turn the power switch off, remove the power plug
from the AC outlet, and contact your dealer. If you continue using the unit without heeding this instruction,
fire or electrical shock may result.
• If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a replacement. Using the
unit with a damaged power cord is a fire and electrical shock hazard.
• Except for the safety cover, never remove anything else from this device. (Please refer to page 8 about the Euro-
block connectors.) You could receive an electrical shock. If you think internal inspection, maintenance, or
repair is necessary, contact your dealer.
• Do not modify the unit. Doing so is a fire and electrical shock hazard.
• If lightning begins to occur, turn off the power switch of the unit as soon as possible, and unplug the power
cable plug from the electrical outlet.
• If there is a possibility of lightning, do not touch the power cable plug if it is still connected. Doing so may be
an electrical shock hazard.

Cautions

• When rack-mounting the unit, allow enough free space around the unit for normal ventilation. This should
be: 10 cm at the sides, 40 cm behind, and 30 cm above.
For normal ventilation during use, remove the rear of the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up inside and may cause a fire.
• This unit has ventilation holes at the top, bottom, and sides to prevent the internal temperature rising too
high. Do not block them. Blocked ventilation holes are a fire hazard.
• Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A damaged power
cord is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.

Operating Notes

• Using a mobile telephone near this unit may induce noise. If noise occurs, use the telephone away from the
unit.
• XLR-type connectors are wired as follows:
pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
• Refer to the “Connector polarity” chart on page 7 for information on the pin wiring of the XLR connector and
phone jack.
• The performance of components with moving contacts, such switches, rotary controls, faders, and connectors,
deteriorates over time. The rate of deterioration depends on the operating environment and is unavoidable.
Consult your dealer about replacing defective components.
• Use only the specific screws that are provided with the MV800 to attach the supplied security cover. Also, after
wiring the Euro-block connectors, use the same screws that held the security cover in place when replacing the
cover.
The use of any other screws may result in damage.
