1. Preset Recall The four contact closure connections on the back panel euroblock allow for four different amplifier stored presets to be loaded at the instant a remote switch is closed Presets are configured from Protea software and can include gain settings mute status polarity as well as the full set of DSP functions if the amp has the DSP option installed The NE amplifier will store up to 35 named internal presets each preset storing control data for all channels and audio functions While working in Protea software changes to an individual preset can be saved to the amplifier using Preset Options Save Preset To Protea or saved to the PC using Preset Options Save To Disk Sub Presets collections of DSP parameters individually selected from software are saved in a similar fashion Individual preset files use the extension pmc The only way to load presets to an amplifier is by using Protea software to recall files saved on either the PC or the amplifier itself through the use of contact closures or with a WR 5 wall mounted remote control Contact closures can load presets 1 4 from the amplifier memory using switches wired to the rear panel contact closure euroblock connec tor Caution A new preset may have dramatically different settings capable of damaging sound system components so be careful not to recall the wrong preset while the system is on Data Control The Data Control euroblock connector on the back2. Remote Standby These two contact closure pins are wired to a switch to remotely place the amp in standby ao NN A Preset Recall These four pins and GND can be wired to remote contact closure switches to recall up to four amplifier presets 9 Data These four pins can be wired to remote microprocessor based controllers such as the WR 5 or RD 8C 10 Remote Level Control These pins can be wired to remote potentiometers such as the WR 1 for level control of individual channels 11 AC Inlet Used for the detachable AC cord WARNING Do not remove or lift the mains connector ground Installation Before connecting to mains power make sure that the switches and wiring are all set to the configuration needed for your particular application Failure to do so could result in damage to the unit or other components in your system CAUTION When mounting or connecting the amplifier always disconnect it from the mains Use four screws and washers when mounting the amplifier to the front rack rails Rear support is also recommended especially for mobile or touring use To reduce the risk of fire or electric shock do not expose this apparatus to rain or moisture Requirements NE series multichannel amplifiers have specific physical electrical and signal requirements for proper operation These requirements will vary depending on your specific application setup and the settings on the amplifier When setting up and testing your sys
