VP7210DP Input Panel
See Figure 1
The VP7210DP input panel features analog audio inputs and sophisticated onboard digital signal processing
technology. Precision Bandpass limiting, pre-equalization filters and automatic self-protection functions
ensure optimized 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) FLAT/80 Hz HP
a) 2-Position push-button DSP preset
selection switch, enables the desired
function. When set in the “FLAT”
position, frequency response is linear
and unaltered. When 80 Hz HP is
selected, the system high pass filter
is raised to 80 Hz, creating an 80
Hz crossover point compatible with
external subwoofers.
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.
