UniAmp Power Amplifier Module , Model 1214
4. PrESEtS
NEtWork CoNNECtIoNS
Two latching 5-pin XLR connectors are fitted for
RS-485 network interconnections. A PC running
WinControl may be connected, via an appropriate
interface (either RS-232 to RS-485 or USB to RS-485) to
the Input connector, if control and monitoring during
operation are required. The Link connector (male) is
to facilitate easy connection to another WinControl-
supported device (e.g. an adjacent enclosure).
The network connectors should be wired as follows:
See page 11 for information regarding suitable
network cable types. See Section 7 (Configuring with
WinControl) for more information about network
operation and software options.
The UniAmp 1214’s DSP section includes 8 Presets;
memory locations in which sets of configuration
parameters can be stored. These permit the
loudspeaker cabinet to be “fine-tuned” to suit
different types of programme material and venue.
When a settings file is loaded into the unit from a
PC, the user can specify in WinControl which Preset
memory it will be loaded into.
rECALLING PrESEtS
The simplest method of recalling a previously-saved
Preset is via WinControl. This necessitates a network
connection to the loudspeaker system. Refer to the
WinControl Help files for further information.
If a network connection is not in place, or a PC with
WinControl is unavailable, Presets may be recalled
manually using the Reset & Preset Control button.
This button is hidden behind a small access hole on
the amplifier module’s conector panel, and can be
accessed with an implement such as a fine jewellers’
screwdriver or a straightened-out paper clip.
A single short press (< 1 sec) on this button will
increment the current Preset number, i.e. if the system
is currently running Preset 2, pressing the button will
load Preset 3. While the button is pressed, the Status
LED will change colour from green to red. Loading of
the next Preset is confirmed by the LED flashing the
appropriate number of times, i.e., it will flash 3 times
when Preset 3 is loaded. Using this method, repeated
button presses will load each Preset in turn.
Note that the amplifier module always
powers-up with the last-used Preset active.
Note also that a long (> 1 sec) button press
has a different function (see following page).
