MIX LED [3] (See Figure 24, below.) flashes green. Remember that the
AUX INPUT LED [2] does not indicate audio level, but the presence of
audio only.
Step 3
Adjust the level of the external audio source feeding into the power amplifier
so that the PA LEVEL LED [4] flashes green. During normal operation, the
LED may occasionally flash red on peaks.
Step 4
Adjust the PA LEVEL control [8] for a comfortable listening level.
Remember, the PA LEVEL LED [4] indicates the level of audio being
received from the external audio source. It does not indicate the level you
set with the PA LEVEL control.
As shipped from the factory, the MPAII has 12 preset programs. One of these
programs should suffice for most acoustic environments. However, should
circumstances require, six of the 12 programs can be adjusted to meet specific
needs or custom programs can be generated (see Custom Programming, Page 17).
Factory Default Programs
As shipped from the factory, the MPAII has 12 preset programs: six factory
defaults which cannot be altered (indicated by a green PA LEVEL LED [4])
and six customizable programs (indicated by a red PA LEVEL LED [4]).
The six “red” programs, when shipped, are identical to the six “green”
programs. We recommend trying each of the six green programs in your
installation. In most cases, one of the green programs will be suitable for
your application. However, should the green programs fail to produce the
desired outcome, you can fine-tune one of the red programs by selecting the
red program that most closely fits your needs and modifying it.
User-Configuration Programs
The MPAII can be programmed to solve specific problems in virtually any
acoustic environment. Any of the parameters which control the MPAII’s
operation can be changed and stored in any of the six red programs.
Step 1
To select one of the six green programs or one of the six red programs, press
and hold the PROGRAM ENABLE button [9] (Figure 24, above). When
this button is pressed, the MIC 1–8 LEDs [1] will momentarily light up, one
at a time, indicating that the MPAII is ready to accept a new program; the
LEDs will stop on the currently selected program, which will be be displayed
