Harman JBL Professional PRX800 Series - Subwoofer Model Features

17
Features
1. POLARITY LED – This light indicates whether the
polarity is set to Normal or Inverse Polarity. When
the light is ON, speaker polarity is inverted.
2. POLARITY Button – This push button allows you
to choose between 0° (Normal) or 180° (Inverse
Polarity). The correct polarity setting will produce
the best blend between the subwoofer and the
full-range speaker and the strongest perceived
bass response at the listening position. If the bass
response seems weak, try inverting the polarity.
NOTE: This button is also used to Factory Reset
speaker settings. See “FACTORY RESETS” on
page 19 for more information.
3. FRONT LED Button – This push button allows
you to turn on/off the Power LED on the front of
the speaker. The front LED will illuminate BLUE
when the system has power and is ready to pass
audio.
4. LIMIT Indicator – There is one YELLOW LED
indicator that will illuminate when input clipping
occurs or peak output has been reached and the
DSP limiter is acting.
5. GAIN Knob – This gain knob is for setting the
input level. The 12 o’clock position is a good
starting point for most uses. Once the full-range
system has been connected the level can be
varied to match and deliver the desired balance.
6. SIGNAL Indicator – There is one GREEN LED
that will illuminate when signal is present.
7. XLR Inputs – Female balanced XLR and 1/4 inch
phone jack combo input connectors.
8. WI-FI LINK LED – This LED has four states:
a. Off – The speaker is not connected to WI-FI.
b. On – The speaker is connected to WI-FI.
c. Blinking Slowly – The speaker is in Access
Point mode and has not yet established a WI-
FI connection.
d. Blinking Rapidly – The speaker is in Access
Point mode and is communicating with a
connected device.
9. WI-FI CONNECT Button – This button is used
to connect to a WI-FI network for speaker
conguration and control using the PRX Connect
application. This button has two functions:
a. Press and release – Instructs the speaker to
try connecting to the congured WI-FI network.
b. Press and hold for 2 seconds – Switches
between “Access Point” and “Normal” network
operating modes. By default, the speaker is in
“Normal” network operating mode. Switching
to Access Point mode allows all PRX800
speakers in a system to be initially congured
for your network router. When switched to
Access Point mode, the WI-FI LINK LED will
ash slowly.
For more information on using WI-FI, see “WI-FI
SETUP” on page 18.
10. HI-PASS LED – This LED will light to indicate the
HI-PASS lter is enabled on the THRU connector.
11. HI-PASS Button – This push button determines
whether the signal coming out of the THRU
connector is unaltered (FULL RANGE) or has
a high-pass lter (HI PASS) applied to it. By
default, the speaker is in a FULL RANGE mode.
If HI PASS is selected, an 80Hz 24dB/Octave
high-pass lter is applied to the signal coming
out of the THRU connector. Engaging the high-
pass lter allows for a smooth transition between
the subwoofer and full-range speaker that is
connected to the output connector. This button
must be pressed and held for 2 seconds to switch
between options.
12. THRU Connectors – Male balanced XLR output
connector. This connector provides a FULL
RANGE or HI PASS signal depending on the
setting of the HI-PASS button. In addition to
connecting a full-range system to the output, it’s
also possible to daisy chain subwoofers together.
13. REMOTE EQ LED – Indicates the speaker has
settings applied by the WI-FI application.
14. POWER LED – This LED illuminates when the
“Power Switch” has been turned to the on position.
It will illuminate BLUE when the system has power
and is ready to pass audio.
