Bridge Plate Rack Mounting (Side-by-Side)

The XPA U 1004 SB and XPA U 2002 SB ship with a bridge plate connector to connect two amplifiers together and form a full rack-
width unit. Mount and connect two amplifiers as follows:
If the amplifier has its flat bottom rubber feet installed, remove them.
1.
Position two amplifiers upside down and next to each other as shown below.
2.
Use the bridge plate connector and the four provided #4 machine screws to connect the two units together (
3.
Attach the two short rack ears to the units with the four provided #6 machine screws (
4.
Insert the amplifier into the rack and align the holes in the rack ears with the holes on the rack.
5.
Secure the amplifier to the rack using the four provided 10-32 x 3/4" screws (

Ventilation Recommendation

Excessive heat can decrease a power amplifier's lifetime. An Over
Temp LED indicator on the front panel lights red when the maximum
recommended operating temperature of +122 °F (+50 °C) has been
surpassed.
To minimize the chances of overheating, the amplifier should be arranged
in a rack so that the evironment does not reach or surpass +122 °F (+50
°C). See the image to the right to see the most optimal way to arrange the
XPA U 1004 or XPA U 2002 SB. No more than four stacks of amplifiers
in a one-on-top-of-the-other arrangement should occur without an open
between the stacks.
The XPA U 1004 SB and XPA U 2002 SB can also be arranged directly
above or below a non-XPA Ultra device, but in any case, the environment
should still not reach or exceed +122 °F (+50 °C).
