5. TROUBLESHOOTING
No AC Power
1) Is the detachable AC power cord properly installed? Is it plugged into a known live outlet?
2) Has the Power switch been disabled in software? (sec 4 .2a)
3) Is the amplifier in Standby Mode? (sec 4 .2b)
4) Is the Power On Delay time set excessively high? (sec 3 .2)
Amplifier Not Recognized in Protea
ne
Control Software
1) Is the PC successfully communicating with the network? (sec 2 .3)
2) Is the amplifier succesfully communicating with the network? (sec 2 .3d)
3) Does the device name appear as green text or red text in the left side menu tree? If red, the
amplifier is unpowered or offline . (sec 3 .1a)
4) Is the amplifier device icon placed on the software project canvas a
virtual device
instead of a
live amp? Any virtual device MAC address will always read FF-FF-FF-FF-FF-FF . (sec 3 .4c)
5) Was the amplifier IP address autodetected (recommended) or manually assigned? (sec 2 .3a)
6) Is firewall software blocking communication from the device? (sec 2 .3b)
No Amplifier Output
1) Is the Amplifier in Protect Mode? (sec 2 .6)
2) Is the input signal properly wired to either a mic/line input or summed mono RCA input?
3) Are front panel, remote control, or software control surface attenuators turned down?
4) Is the signal muted from within the control surface, DSP section, input source select, remote
control, output mixer, or event scheduler?
5) Are dynamics and any gain tool settings in the DSP section allowing signal to pass properly?
6) Is the signal properly routed to the desired output in the DSP cross point matrix? (sec 3 .4d)
7) Is the level fader set properly in the DSP output channel mixer?
8) Did the event scheduler change a preset or the output channel source? (sec 3 .4g)
Attenuators Don't Work
1) In the device software control surface, are the front panel or remote attenuators disabled?
Unable to Access All Software Features
1) Is desired level of access granted to the current user in the security tab?
Unable to Load Enough DSP Tools
1) Is the sample rate set to 96kHz? (sec 3 .2)
2) Graphic Equalizers have a much greater DSP "cost" than Parametric Filters . Feedback
Suppressor and FIR filters use even more DSP than the Graphic EQ . Use only as much EQ
as is needed . Note that FIR filter and Feedback Suppressor are mutually exclusive for a given
DSP channel I/O, meaning only one or the other can be plugged into that channel number .
Can't Use Any DSP Tools On Input or Output Channels
1) Has Input, Mixer, or Output channel DSP been disabled under Device Options? (sec 3 .2)
WR-5 Doesn't Work Properly
1) Is the WR-5 wired correctly to the amplifier Data connector? (sec 4 .1c)
2) If the WR-5 is the last one in series, even if it is the only one used, is the two pin jumper
properly placed on the circuit board header as shown? (sec 4 .1c)
3) Is the WR-5 assigned its own unique device ID from within its device window?
4) If using WR-5 for gain control, be sure to install a (ne)WR-5 Remote Gain function in a DSP
gain block on the channel to be controlled
