Speaker connection
Before loudspeakers are connected to the Speakon® outputs of the PowerPac 4003 DSP the corresponding preset
must be loaded on the signal processor! Only with the correct presets specially developed for the loudspeakers by
PL-AUDIO reach their maximum performance, the best possible sound and the necessary operational reliability. By
loading the wrong the speakers my sound bad and / or may be damaged through overload!
If you want to operate loudspeakers from other manufacturers on the PowerPac 4003 DSP, there are enough free
preset memory spaces available on the device! As a starting point we recommend the "01. Sub + Top
Standard“
preset to be loaded and sent to your speakers plus conducting the absolutely necessary adjustments (gain, HPF,
LPF, EQ, limiter, etc.).
The Speakon® sockets (13) on the rear of the device (section 2.2.) are for the system cabling intended. The system
cabling is between the power amplifier and a sub / top combination and only a single 4-pole Speakon® cable has
to be laid to each side of the system. Pins 1 + / 1- are wired for the tops, while pins
2 + / 2- are wired for the bass. 2-way actively separated loudspeakers do not have a built-in passive crossover. On
such loudspeakers, each path has its own amplifier channel. An amplifier channel operates the midrange speaker
(s) (e.g. channel 2 - mid) while another amplifier channel drives the Tweeter(s) (e.g. channel 3 - high). This Bi-Amp
system uses a 4-pole Speakon® cable between Speakon® connector (14, red) and loudspeaker, where pins 1 + / 1-
transmit the processed and amplified signal of channel 2, while the processed and amplified signal of channel 3 is
transmitted via pins 2 + / 2-. When wiring bi-amp systems it must be worked out with particular care, as incorrect
cabling quickly leads to possible destruction of the high-frequency driver!
SELECTING THE CORRECT PRESET IS ABSOLUTELY CRUICAL FOR CORRECT OPERATION, CORRECT
CONFIGURED OUTPUT AND MAXIMUM SOUND QUALITY!!!
PL-Audio Bi-Amp presets are usually locked in the signal processor with password protection in order to prevent
unintentional changing of the parameters. If you make changes here do this very carefully, with caution and
expertise! The signal processor allows very deep and detailed, but also serious changes in the transmission
parameters of the speaker system! To change the bi-amp presets, log in with the password:"Admin1" in the
administrator user level of the signal processor. Now you have full access to change all necessary parameters.
This is easy and convenient with the PL-Audio DSP-CONTROL software on the PC.
