12. RACK MOUNTING BRACKET ATTACHMENT
To mount the BG-115 (BG-130) in a standard 19" equipment rack, use the optional MB-25B-BK or MB-25B-J
Rack Mounting Kit.
Before attaching the rack mounting bracket, remove each 2 frontmost screws on both sides of the amplifier.
These removed screws are not used for rack mounting.
Notes
• Rack mounting screws are not supplied with the unit. Use the screws that are appropriate for the rack.
• When mounting the unit in an equipment rack, the inside
of the rack must be sufficiently ventilated.
To achieve sufficient ventilation, also mount the optional
PF-511 Perforated Panel (1U*):
(1) at the top and the bottom of the rack, and
(2) above and below the unit.
* 1U size = 44.5 mm or 1.75" (reference size)
[MB-25B-BK]
Remove four plastic feet on the bottom surface.
Note that these removed screws are not used.
Attach the MB-25B-BK to the amplifier using the
supplied four screws.
When using other screws, see to it that each
screw is shorter than 15 mm (0.59").
[MB-25B-J]
The MB-25B-J is designed to mount two BG-115s
(BG-130s) in a single rack.
When using this bracket, remove four plastic feet
on the bottom surface of each amplifier and joint
the two amplifiers with a joint bracket, as
illustrated at right.
Then attach the brackets using the supplied four
screws. When using other screws, see to it that
each screw is shorter than 16 mm (0.63").

11. 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 105°C (221°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.
