When first turning on the sound system, switch on all upstream electronics first, then the PV
control fully counterclockwise (all the way down). Begin checking levels with the mixer output level controls all
the way down, and bring them up slowly with the PV
the way up is recommended as a starting point).
Using the SPEAKER OUT jack
The PV 115D has a SPEAKER OUT, a 1 / 4" phone jack output on the rear panel. An external full-range passive
®
speaker system (such as a PV
external speaker must be an 8-ohm impedance or higher. YOU CAN NOT CONNECT A 4-OHM SPEAKER TO THIS
JACK, IT WILL CAUSE THE AMPLIFIER TO SHUT DOWN. Impedances lower than 8-ohms nominal are not allowed.
For best results when using this jack, the external speaker connected to it should be of a similar sensitivity to
the PV115D, which has a sensitivity around 95 dB for 1w/1M. If the external speaker has a higher sensitivity, it
will play louder than the PV
has a lower sensitivity, then it will play softer than the PV
Another consideration is to place the external speaker as far away as is practical, to increase the overall
coverage of the room, and to minimize the interference patterns that occur when two loudspeakers are near one
another and radiating the same signal. Placing the external speaker at least 20-25 feet away from the PV
would be a good practice. This would correspond to an example of having the PV
and the external speaker on the other side.
USE WITH A PASSIVE ADD-ON SUBWOOFER
Non-powered subwoofers that have a built-in high frequency roll-off (often referred to as "add-on" subwoofers),
can also be used with this output, as long as the nominal impedance is 8-ohms or above.
The PV 118 Sub is in this category, and can be used with this output jack. Normally, the closer to the PV
®
the Sub is placed, the better it will work WITH the PV
a built-in pole guide for placing a pole stand for the PV
with the PV 115D.
®
Use of the PV 115D with a powered Subwoofer
®
Powered subwoofers often have a built-in electronic crossover to allow a high-pass filtered signal (lows
rolled-off ) to be sent to the upper range speaker. The PV
PV 115D with this type of powered subwoofer, first run the signal from the mixer or signal source to the
®
powered sub input, then come out of the combo jack labeled "THRU/HPF" and send that signal to the PV
input jack. On the PV 118D Sub, the button to the far left labeled THRU/HPF should be pushed in to engage the
®
high-pass filter (HPF). On other powered subwoofers, if they have a similar high-pass filter function, send the
signal in and out of the subwoofer according to the Manufacturer's instructions, which should be similar to the
instructions as outlined above.
Use of the PV 115D with a Speaker Stand
®
The PV 115D has a stand mount cup on the bottom so that the system can be stand mounted on a standard 1
®
3/8" (36mm) diameter stand pole.
When using stands or poles, be sure to follow these precautions:
A. Check the stand or pole specs to make sure that it can support the weight of the PV
and observe all safety precautions stated by the stand manufacturer, including the maximum height the stand is
rated for.
B. Always place the stand on a flat, level and stable surface, and be sure to fully extend the stand legs as per
the stand manufacturer's instructions.
C. Try to make sure that the stand legs are oriented for the least danger of tripping to those in the vicinity of
the stand. Never block a doorway or hallway with the legs of a stand.
D. Try to route cables so that people will not trip over them or tip the speaker over. Use of duct tape, cable
channels or guards, or other appropriate tie-down/cover –up devices should be carefully considered and
implemented.
