ALLDSP PLP428
1. Overview of Connectors and Controls
In addition to the available features described in this manual, you also have the option of controlling the
processor remotely over your network. Please refer to the Software Manual for details.
1.1. Front Panel
1.1.1. USB Connector
The USB connector is used to connect the PLP428 to a PC or MAC. It can then be configured and controlled
in real time with the freely available PC and MAC configuration program. Please check our website regularly
for updates.
1.1.2. Input VU Meters
There are 6 independent input meters available. The LEDs indicate the signal level at the inputs, in dBu, after
the input gain faders. The Peak LED lights when the input level e20dBu.
1.1.3. Function Buttons
The function buttons allow direct access to all editing and navigating functions. See section three for a
detailed description on the functions of each of these buttons.
1.1.4. Rotary Encoder
The rotary encoder is used to scroll through the menu items by pushing it, and to adjust values by rotating it.
When values are changed, the DSP is updated in real-time.
1.1.5. Output VU Meters
There are eight independent output meters available. The indication refers to the output level w.r.t. the
threshold of the output peak limiter. The Limit LED lights when any gain reduction is taking place in that
channel. The Peak LED lights when more than 12dB of gain reduction is taking place.
1.1.6. Output Mute Buttons
The eight output mute buttons are used to independently mute each output.
1.2. Rear Panel
1.2.1. Power Connector
The PLP428 has an internal power supply that will accept voltages ranging from 100V - 240V at frequencies
from 50Hz-60Hz. A power cord is included.
