that can be controlled through the serial port include setting of the 4
parametric bands, level control and selection of the 16 stored programs.
Via a single PC, any number of speakers may be controlled. Each speaker
has a channel ID number (from 1 to 16). Any speaker with the same ID
will be controlled at the same time. This means that you can have 16
speakers addressed individually, or an unlimited number controlled the
same.
The Electronics
The ProLinear is bi-amplified with typically 80 watts for the woofer and 40
watts for the tweeter. (In actuality, the woofer and tweeter are both
powered at 80 watts, but because of the higher efficiency and lower
power content to the tweeter, only about 40 watts is needed to match the
80 watts to the woofer.) The amplifiers are low distortion, wide band
devices that are self-protected to prevent damage to the drivers. Inputs
are either analog XLR or ¼” TRS, so digital mixers and sources are not
required. The power supply is a high efficiency switching supply used to
provide optimal power at a low weight, as well as being usable over a
wide range of AC voltages without reconfiguring the speaker.
The front panel/display of the speaker allows the user to control all the
functions of the speaker if a PC is not available. Multiple speakers can
also be controlled from a single speaker. The LCD provides a readout of
all parameters and flashes red to indicate that the speaker is being
overdriven.
