The following functions within the Pema amplifier can be remotely controlled. A listing of the devices by which each
function can be controlled is shown below and explained in the following paragraphs:

4.2a Power Switch Disable
When the power switch is turned off the amplifier is completely off, UNLESS the power switch has been disabled from
ne
within Protea software (Control Surface Tab), in which case the power switch on the amplifier has no effect at all. If the power
switch has been disabled from software, the Pema amplifier front panel DISABLE LED will be lit. Even if the AC power is
removed, the amplifier's internal memory will maintain the <power switch disabled> status until changed again from Protea
software. Performing a factory reset will clear and restore all internal amplifier memory to factory settings.
4.2b On/Off/Remote Standby
Pema amplifiers have three possible power states, OFF, ON, and STANDBY, each
with a status LED on the front panel. Control for these states is managed by the following:
1) Remote Standby Contact Closure - When the two Euroblock pins labeled "Remote
Standby"on the back of the amplifier are wired to a switch and connected, the amplifier goes
into Standby mode, meaning the amplifier is active but not fully powered up. For remote
standby to work, the power switch must be turned on OR be disabled through Protea
ware. Open the switch to remove the amp from remote standby mode.

2) Protea Software On/Standby - On/Standby in the Pema amplifier software func-
tions the same as the hardware based remote standby contact closure on the back panel. The
software standby control does not override the Remote Standby contact closure control, they
both remain active at all times. See Control Surface Tab descriptions on page 11.
3) Event Scheduler - Protea
the event scheduler, the installer can assign one or more times of day or days of the week for the amplifier to automatically go
into and come out of standby mode, disabling overall function and conserving power during those times when the amplifier is
not being used. See the Event Scheduler Tab description on page 16.
4) iPad - A Standby On/Off control button can be part of an iPad design, behaving the same as software standby.
4.2c Remote Preset Recall
A preset file is created when the user has made all required software settings, DSP processing settings, source selection,
signal routing, mixing, etc, for a given application using this device. A preset is essentially a snapshot of all current settings on
a given amplifier. This Pema amplifier can internally store up to 31 named presets, each preset storing control data for all chan-
nels and audio functions. Individual preset files stored on a PC use the extension (*.pmc). While working in Protea
