2.3b Firewalls - If Protea
as fi rewalls may block the Pema or NE device response to the controlling PC when network communication is attempted. The
current PC fi rewall status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the
security shield where the fi rewall can then be disabled. Once communications with the device is established, the fi rewall can
be enabled again, but if there continues to be communications problems then disable the fi rewall.
2.3c Wi-Fi and LAN – For the initial device auto-confi guration process, any secondary Wi-Fi connection should also
be disabled, and the LAN (Local Area Network) connection must be enabled on the PC. Secondary network connections may
confuse the auto device discovery process. Go to the Windows Control Panel, then Network Connections, to disable any second-
ary network connections. Once communications with the device is established, secondary network connections can be enabled
again, unless a communications problem remains with Pema or NE devices, in which case the secondary network connections
should remain disabled.
2.3d Connecting Device(s) - Connect the Ethernet cable from the PC or network router to the Ashly Pema or NE remote
control device. If a successful Ethernet connection has been made, a solid green LED (Link) lights up on the device Ethernet
port. If there is no green LED showing, there is either a problem with the cable or the network source, which must be addressed
before proceeding further. All RJ-45 Ethernet ports fl ash green when active, so backtrack through any other cables, routers, or
switches to fi nd the problem. The fl ashing yellow LED (Data) indicates that data is fl owing to or from the device.

2.4 Front Panel Features

1. Mounting Holes – For rack mounting.
2. Power Switch – Switches the unit on or off. Note: The power switch can be disabled from Protea
3. Status LEDs – Indicate status of: Power, Standby, Protect, Power Switch Disable, and Com activity.
4. Air Infl ow Vents – Cool air enters here and is vented out through the sides.
5. Channel Controls – Channel control area.
6. Signal LEDs – The lowest LED will begin to light when the output voltage reaches -18dBu below rated output. The
Clip LEDs will begin to fl ash when output voltage is 1/2 volt below the output power supply voltage, or the front end is clipped.
7. Bridge – This LED indicates that the channel pair is selected to BRIDGE mode from within Protea
only the odd input channel level control is active.
8. Temp and Current LEDs – The Temp LED indicates that the amplifi er channel has reached an excessively high operat-
ing temperature and will gradually attenuate the signal to compensate. If unable to suffi ciently cool the channel, the amplifi er
will eventually go into protect mode. The Current LED confi rms that the amplifi er output is delivered to a speaker load.
9. Channel Attenuators – These control the input signal level to the amp, and can be disabled from software.
10. Factory Reset – To reset all internal confi gurations (including presets and passwords) back to the original factory set-
tings, press and hold this recessed front panel momentary switch during power up until all channel LEDs sequence from bottom
to top. Upon reset completion, the LEDs will turn off and the amp will be in normal operating mode.
