UniAmp Power Amplifier Module , Model 1214
Correct operation of a UniAmp 1214 module may be
confirmed using WinControl software.
A full description of WinControl is beyond the scope
of this manual and further information is available
in the application’s Help files. Instructions on how
to install WinControl on a PC are included with
the Program Set. Instructions on the use of the JBL
Professional
®
RS-485 interface are included with the
interface itself.
CoNNECtING to A PC
The PC connects to the amplifier module via an RS-
485 interface adapter. (Two versions of adapter are
available from JBL Professional, for connecting to PCs
either via a USB or an RS-232 port). Use either a 5-pin
XLR female to 5-pin XLR male cable or a 9-pin Dsub
to 5-pin XLR male. These cables (5 m in length) are
supplied with the WinControl Program Set, the type
depends on the RS-485 interface type. The RS-485
interface should then be connected to either the PC’s
9-pin COM port (in the case of a RS-232 to RS-485
interface) or a USB port (in the case of a USB to RS-
485 interface).
BASIC SoFtWArE oPtIoNS
WinControl allows the various parameters of the
UniAmp’s DSP section to be set according to the
installer’s wishes. This enables the performance of
the loudspeaker enclosure to be accurately optimised
to suit both the venue and the type of programme
material being handled (speech, rock, opera, etc.)
The particular set of parameters which can be
adjusted via WinControl varies with loudspeaker
model. Typically, it includes delay, gain and multi-
band parametric EQ.
In addition to the parameters determining the audio
performance, the various Preset memories may
have alternative configurations stored in them, and
recalled as required. Unit monitoring may also be
configured, with the conditions for a fault state to be
signalled being registered. Additionally, units may be
‘grouped’ together in software, allowing very rapid
adjustment of multiple devices.
Full details of the options available within WinControl
are available in the application’s Help files.
