VP7212MDP Input Panel
See Figure 2
The VP7212MDP input panel is optimized for high impact stage monitor use and features analog audio
inputs and sophisticated onboard digital signal processing technology. Precision Bandpass limiting, pre-
equalization filters and application specific DSP presets ensure flexible and reliable performance. JBL
engineers have calibrated DSP speaker management and limiter parameters to ensure smooth phase
response and transfer function curves right out of the box.
CONTROLS
1) DUAL WEDGE TUNING
a) 2-Position DSP preset selection switch, enables the
desired function. When set in the “SINGLE” position,
frequency response is optimized for single wedge
performance. In the “DUAL” position, low and mid-
high frequencies are contoured to optimize dual wedge
coupling.
2) ATTENUATION
a) 16 dB Precision Detented rotary input
sensitivity control, 0.5 dB steps.
Sensitivity +4 dBu nominal (+20 dBu
clip) with the control fully counter
clockwise, and -10 dBv nominal
(+4 dBu clip) with the control fully
clockwise.
3) RESET
a) Press to reset line voltage circuit breaker.
4) LINE SELECT
a) 2-position slide switch, set to 115V position for (100-
120V~) or 230V position for (220-240V~) operation.
INDICATORS
5) PEAK
a) (Clip) Red LED, Clip detection monitors input, DSP, and
each amplifier output channel. The LED illuminates when overload at any point is detected.
6) SIG
a) (Signal) Green LED, detects input signal, illuminates above the threshold set at –70 dBu.
7) POWER
a) Blue LED – located near voltage select switch, illuminates when AC power is applied and unit is ready for
operation.
