Remote Preset Recall; Remote Gain Control - Ashly Pema 8250 Operating Manual

Operating Manual - Pema Protea Equipped Media Amplifi er
2) Protea ne
software functions the same as the hardware based remote standby contact closure
on the back panel. Clicking on Standby in the Pema amplifi er software control
surface places the unit into standby mode until further action is taken to bring the
amp out of standby. 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
key Pema amplifi er functions including placing the unit into standby mode. With
the event scheduler, the installer can assign one or more times of day or days of
the week for the amplifi er to automatically go into and come out of standby mode,
disabling overall function and conserving power during those times when the amplifi er
is not being used. See the Event Scheduler Tab description on page 16.
4.2c Remote Preset Recall
A preset fi le 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 amplifi er. This Pema amplifi er can internally store up to 31 named presets, each preset stor-
ing control data for all channels and audio functions. Individual preset fi les stored on a PC use the extension (*.pmc).
While working in Protea
tions/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.
Presets can be recalled to the Pema amplifi er using the following methods:
1) Protea Software - Use a direct or network Ethernet connection from the amplifi er to a PC using Protea
ne
software. Click (Preset Options >Recall From Disk/Recall From Protea) to load a stored preset into the amplifi er.
2) Contact Closure - The four contact closure connections on the amplifi er back panel allow for amplifi er presets
#1-4 (presets already saved and stored in the amplifi er memory) to be loaded into the Pema amplifi er at the instant a
remote switch connected to one of pins 1-4 is connected to its ground pin.
3) WR-5 - A WR-5 will appear in software as a captive device to its host amplifi er. The six buttons on the WR-5
can be programmed to recall a specifi c amplifi er preset, or scroll through a defi ned list of presets.
4) neWR-5 - A neWR-5 will appear in the software menu tree as a device on the network, and must be assigned
to the Pema amplifi er under control. Like the WR-5, the six buttons on the neWR-5 can be programmed to recall a
specifi c amplifi er preset, or scroll through a defi ned list of presets.
5) Event Scheduler - Protea
including preset recall. With the event scheduler, the installer can assign one or more times of day or days of the week
for the Pema amplifi er to automatically recall and load a new preset.
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.
4.2d Remote Gain Control
1) WR-1 DC Level Control - The WR-1 remote potentiometer functions as if it were a front panel attenuator
but in a remote location. Attenuation from a remote DC level control attenuator is cumulative with all other attenuation
for a given channel, including the front panel level control.
2) WR-5 - The WR-5 can be programmed to select single or multiple input or output channels for remote gain
control function. After programming one of the six buttons for gain control, then pressing that button, pressing the
WR-5 up/down buttons will adjust the gain for all selected channels associated with that button. A gain range can also
