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

Ventilation Recommendation
Excessive heat decreases the optimal lifetime of the power amplifier. An
Over Temp LED indicator on the front panel of the amplifier lights red
when the recommended operating temperature has been exceeded.
The NetPA Ultra amplifiers need to be arranged in a rack environment, so
that the environment around the amplifier around does not reach or exceed
+122 °F (+50 °C). No more than four amplifiers should be stacked one-
on-top-of-the-other without an open rack space in between as seen in the
image to the right.
The NetPA Ultra amplifiers can also be arranged above or below a non-
NetPA Ultra device.
