interference rejection, a balanced cable using either the balanced TRS 1/4"
phone plug or the XLR plug will provide superior interference rejection and
performance.
Sometimes, with difficult interference problems, it will be helpful to lift the shield
ground ( Pin #1 of an XLR) of a balanced cable at the
PVX™p 10 Bluetooth®
end. Check any input changes carefully, always turning the Level control down
before plugging and unplugging cables, or lifting the ground.
Use of high quality, premium cables is recommended for the
PVX™p 10
Bluetooth®, as these usually have better shielding and materials and will provide
greater long-term reliability. The best option is a shielded balanced cable no
longer than necessary to reach the
PVX™p 10 Bluetooth®. It is usually a good
idea to leave some slack at the input to the
PVX™p 10 Bluetooth® and also to
tape the cables down or run them under a cable guard to avoid anyone tripping
over them or pulling the
PVX™p 10 Bluetooth® over when stand mounted.
Level Control Adjustment
The
PVX™p 10 Bluetooth® is equipped with a Level controls (5a, b and c)) on
the inputs to facilitate use in many different applications. With the Rear Panel
Level control adjusted fully clockwise, and the DSP Master Gain at +10 dB, and
the DSP Channel Gain at nominal (0 dB), the gain is such that the input
sensitivity is 0.50 V RMS for full-rated output with the Combo jack. There is still
10 dB more gain available in the individual DSP Channel inputs, which makes the
sensitivity with all DSP channel sliders full up, the DSP Master Gain full up, and
the Level control full CW, approximately 0.16 V RMS.
If the
PVX™p 10 Bluetooth® has been Factory Reset, or the App control turned
OFF, then the default gain for the DSP Master Gain is set to 0 dB.
This results in a sensitivity of 1.58 V RMS with the Rear Panel Level control
adjusted fully clockwise, and the DSP Channel Gain at default (0 dB).
We recommend the following gain structure for the
PVX™p 10 Bluetooth®
speaker system:
Rear Panel Level control starting out at straight up
DSP Master Gain at +10 dB
DSP Channel Gain at 0 dB
This results in a sensitivity of 1.58 V RMS for full power output.
When driving the
PVX™p 10 Bluetooth® from a mixer, it may be advantageous
to reduce the input sensitivity by turning the Level control to the halfway point.
The
PVX™p 10 Bluetooth® will now more closely match a typical power amp.
If the mixing board indicates clipping of its output signals, then all of the
PVX™p
10 Bluetooth® power capability is not being utilized cleanly. Clipping the signal
before it gets to the
PVX™p 10 Bluetooth® is not optimal. Reduce the mixer
output level and turn up the Level control on the
PVX™p 10 Bluetooth®.
