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 dened. 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
can be directly wired to LED indicators. Note: When a logic output card is installed, the host expansion slot's front panel
LEDs will all turn red. Examples of a logic output low and logic output high application are shown below:
12. TROUBLESHOOTING TIPS
1) No power - Is the detachable AC cord fully plugged in? Is the rear panel power switch on?
2) Software doesn’t work on unit - Is the ethernet connection properly made? Has the ne24.24M been identied by
the software? Are the LEDs on theRJ-45 ethernet jack showing activity?
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) Mufed 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.
7) Excessive Noise - Set the Input Preamp gain as high as possible while allowing 20dB of headroom before clipping
occurs. Do not use input or output Gain controls for large increases (>20dB) in level from input.
