Operating Manual - Pema Protea Equipped Media Amplifier

4.2

Remote Control Functions:

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

within Protea

ne

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

ne

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 am-

plifier are wired to a switch and connected, the amplifier goes into Standby mode, whereby 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

ne

software. Open

the switch to remove the amp from remote standby mode.
