Operating Manual - ne24.24M Matrix Processor

11. GPO LOGIC OUTPUT

A GPO (General Purpose Output) card can be installed as an option in any one of the four expansion slots, providing

current limited 12V logic outputs for control of 12V or 5V external devices. Once the expansion module is installed, the

software displays a Logic Output tab where each pin's logic function is dened. Logic outputs will issue either a logic high

level (+12VDC at 10mA) or logic low level (0VDC). Maximum current sink is 1A per channel, +100VDC max. The high or

low output state is a function of the currently loaded preset, or can be the result of a WR-5 button programmed to set the logic

output to active high or active low. The logic outputs are current limited to sourcing no more than 10mA so that these outputs

3) No sound - Check to see if the input or output is muted in software or by a remote control action. Is the input

Preamp set for the proper gain? Is the input or output Gain turned down? Is the Noise Gate threshold set too high? Is the Input

to Output Matrix connected as desired? Does the Matrix Mixer section have any signals turned down or muted? If used as a

crossover, make sure the high pass lter (HPF) is set to a lower frequency than the low pass lter (LPF) for a given output. If

using a condenser mic, is Phantom Power turned on (input Preamp)?

4) Clip light stays on - Is the input signal level too high? Is the Input Preamp gain set too high? Are input or output

gain settings too high? Check to see if an EQ lter has too much boost.

5) Distorted sound but no Clip LED- Check individual EQ lters to see if there is excessive boost.

6) Mufed sound - If expecting full range audio on an output, make sure the crossover settings are not inadvertently

set so as to limit the pass band.
