Loudspeaker System Specifications
If the SAME signal is sent in on both channels of the 1/8" input jack, then the
gain is increased by 6 dB, and the sensitivity voltages become 0.089 V RMS and
0.028 V RMS respectively.
It should be noted that this is a very high sensitivity with all the gain controls
turned fully up, and when using the 1/8" input jack, it would be a good idea to
turn down both the Rear Panel Level control, and the DSP Master Gain, and the
DSP Channel Gain to avoid a suddenly very loud signal presence.
A good starting point would be -10 dB on the DSP Master Gain, and also on the
DSP Channel Gain, and start with the Rear Panel Level control down (CCW) all
the way, and turn it up slowly with an active signal source feeding the 1/8" input
jack.
It would be prudent to check your signal source default output setting (as in a
Smart Phone feed), as it is not uncommon for this setting to be at a rather high
level. If you are checking the gain with your device "turned down", and later, you
go to hook it up again, in the meantime, it may have become reset to the default
output level.
Level Indications on the LCD Display Screen (10)
The LCD screen for the DSP menu also displays a set of level indicator bars in
each segment of the display, channels 1, 2, 3 and the Main (Master) segment.
See Fig. A below, and compare to Fig. 1 a little bit further down.
Fig. A Level Indicator Bars
These indicator bars can be helpful in determining the relative level between
channels, and to see the overall signal level structure. Note that they do not
respond to quick, short transients, but are more of an averaging style of
indication.
They will not be accurate to try and determine when the system has reached it's
output limits, that would best be determined by turning the front baffle LED
indicator to "Limit" mode, as outlined in the Config menu section below, see Figs
53, 54, and 55 and their associated explanations. Please note the information
provided about when the LED indicator turns RED when the Limit indication
function is selected.
Disconnecting AC Power to the PVX™p 12
We recommend that the Power switch (3) be used to turn the unit off first, and
then the AC power cord can be removed, this minimizes stress to the power
amplifiers and the transducers from turn-off transients. The power switch has an
