Installing an
APS
module...
(see photo - page 1)
All
APS
modules install into the
APS 25b
in the same manner. To
install, first remove the blank panel by loosening the two retaining thumb
screws. Next remove the “shorting board” by pulling it straight out. Now,
simply slide the module into the slot and lightly press until the connector
in the rear engages and the front panel is flush. Last, replace the two
thumb screws and tighten snugly. Any
APS
module can be inserted into
either slot. Save the “shorting board(s)” for possible later use.
NOTE:
If you purchased your
APS 25b
with
one or two modules, they
have already been installed.
The
APS 25b
Inputs/Outputs and Controls...
A.
MASTER VOLUME CONTROL
- controls the overall volume of the
APS 25b
as well as the
LINE OUT
(8) connector.
B.
TONE
- this is a variable frequency high-cut tone control that is pri-
marily used to reduce high-frequency feedback. The control is
essentially flat when turned fully clockwise and reduces more high
frequencies as it is rotated counterclockwise.
C.
POWER LED
- displays power state of speaker. See (4) for details.
1.
CHAN A
slot - any module can be installed here.
2.
CHAN B
slot - any module can be installed here.
3.
MIC INPUT
- plug a wired dynamic microphone in here. This 1/4
inch
jack is designed to accept a low impedance microphone. The input
volume is controlled by the
MICROPHONE LEVEL
knob (5).
4.
OFF/AUTO/ON
switch - this controls the power for the speaker
after
the
MASTER POWER SWITCH
(12) is placed in the
ON
position.
• The speaker is essentially OFF with this switch in the
OFF
position.
The front panel LED (C) will glow Red.
• The speaker will come ON from its standby mode automatically when
any signal is sensed when the switch is in the
AUTO
position. The
POWER LED (C) will turn from Red to Green. 10 minutes after all
audio stops the speaker will return to its standby mode and the
POWER LED (C) will return to Red.
• The speaker is ON at all times when the switch is in the
ON
position.
The POWER LED (C) will glow Green.
5.
MIC LEVEL
- this knob controls the input volume of the microphone
plugged into the
MIC INPUT
(3). It is always good practice to leave
the control turned all the way down (full counterclockwise) when no
microphone is being used.
6.
LINE LEVEL
- this knob controls the input volume of anything plugged
into the
LINE IN
(7) jack.
