JBL Professional DPC-2 manual VP7212MDP Input Panel, Controls Dual Wedge Tuning

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.	8	1

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	11	10	4
