Connect the Audio Inputs
— Figure 10 —
There are four female XLR connectors labeled 1 through 4 that provide the audio inputs to the PLD amplifiers. A single input can be routed to one
or a combination of outputs. You can use from one to four of the inputs. The inputs are 10 kΩ balanced or unbalanced, with a selectable sensitivity
of either +4 or +14 dBu. There are four male XLR connectors in parallel with the four female connectors. The male XLRs are for daisy chaining to the
inputs of other amplifiers.
1. Make sure your audio source devices are powered off.
2. Connect the input source XLRs to the four female XLRs.
NOTE!: The PLD Series has the capability of routing the inputs to different outputs. Be sure that the connections you make here match
the configuration of the amplifier.
USB (Optional)
The USB cable (supplied) connects to a Mac or PC for use with the Amplifier Navigator software. You can update the amplifier firmware, save and
deploy configuration files, and more. Refer to the Amplifier Navigator online help for details.
Outputs
The PLD amplifiers have four configurable outputs. You can set the power, combine outputs (bridged and parallel), and adjust the DSP for each
output. When the output configuration of the amplifier changes, the output connections, controlled by relays, change accordingly. Use the diagrams
shown in Figure 14 thru Figure 22
Select the Output Configuration
The first step is to select a Preset based on the loudspeakers being connected to the amplifier. You can use a factory preset, and then adjust the
parameters as needed, then save the configuration as a user-defined preset. In addition, you can use the
to create presets from the ground up. When the configuration is changed, all four channels are automatically muted.
