DPA 120
1 x 120 Watt D-Class amplifier, modular
DPA 240
1 x 240 Watt D-Class amplifier, modular
The DPA series of amplifier modules comes in two versions:
120 and 240 Watt. Due to its design, 8 units can be put in
a special 4U/19“ rack frame the RKDPA. In the front of each
module, LED indicators are showing the following status:
- Power (AC/DC)
- Signal
- Fault
Gain adjustment and power-switch are positioned at the rear
of each amplifier module and meant for final adjustment
during commissioning. The D-Class design amplifier is
equipped with a self-regulating ventilator with variable speed
control to reduce power consumption.
The DPA-series of D-Class amplifiers are thoroughly modular. Individually equipped with an AC/DC supply
and industrial cases for higher immunity, these modules are design for industrial purposes and made for
fast replacements. The DPA-series of D-Class amplifier are ready to be housed in a quick-snap 4U, 8-slot
position 19-ich rack-frame.
