10. OPERATION
After completing all connections, turn on the power switch, and check to confirm that the power indicator
lights.
Note
When the heat sink temperature exceeds 85 °C (185 °F), the protection circuit begins to operate to
disconnect the output from the circuit. The disconnected output is automatically restored as soon as the
temperature returns to the normal operating range.
11. INSTALLATION PRECAUTIONS
CAUTION
Keep the amplifier over 10 cm (3.94") away from
objects that may obstruct air flow to prevent the
unit's internal temperature rise.
12. RACK MOUNTING BRACKET ATTACHMENT
To mount the amplifier in a standard 19" equipment rack, use the optional MB-1000 Rack Mounting Bracket.
