DPAN – HiQnet Network Input Module,

Analog Audio with Networking

See Figure 1a

The DPAN input module features analog audio inputs and sophisticated onboard digital signal processing technology. Precision band pass limiting, pre-equalization filters and automatic self-test functions ensure optimized performance. In addition, the DPAN input module adds 100 Mb Ethernet networking functionality and HiQnet compatibility. It enables remote control and monitoring via HiQnet System Architect™ software. Network Control and Monitoring is enabled by the JBL DP-DCP (DrivePack Device Control Panel) supplied within HiQnet System Architect. Network capabilities include monitoring of status, input and output levels, clipping, temperature, load faults and gain reduction. Additional control features available in software include load supervision, dynamic processing, ten internal user defined presets, delays, onboard noise and sine-wave generators, network device event logging, and user alert messaging.

CONTROLS

 

1) ENABLE ALT PRESET button

 

a) Momentary, Enables or Disables the selected function.

��

Factory ALT Preset:

On subwoofer applications, the subwoofer low-pass filter

 

frequency is set to 80 Hz and for full range systems the high-

pass is raised to 80 Hz. (Knee shape and slopes are model

dependent).

 

Internal Controls - Input Sensitivity 2-Position Switch: Located

on the back side of the front panel, full output is achieved by

 

selecting either +4 dBu in one position or +20 dBu in the other

position. Switch positions are marked with silkscreen on the

PWB.

NOTE: Product is shipped factory set to the +20 dBu switch position

 

to provide optimal input gain structure and headroom for most

 

professional audio equipment. Changing the sensitivity switch to the

+4 dBu setting is not recommended unless connection to -10 dBV

equipment is required.

 

INDICATORS

 

2) ENABLE ALT PRESET

a) Orange LED illuminates when the function is enabled.

3) FAULT

 

a) Red LED illuminates during any fault condition.

 

4) THERMAL Protection

 

a) Orange LED illuminates during thermal limiting:

Figure 1a

 

ai) FLASHING indicates first stage of thermal limiting, amplifier output level is reduced to prevent

overheating.

 

aii) SOLID illumination indicates thermal protection is in the second stage of protection and amplifier shut down may occur if immediate action is not taken to correct the external reason for excessive heating of the amplifier.

5)READY

a)Green LED, illuminates when the system is ready for operation

6)SIGNAL/CLIP

a)(Signal) Green LED, detects input signal above the threshold set at –70 dBu

b)(Clip) Red LED, Clip detection monitors input, DSP, and each amplifier output channel.The LED changes from Green to Red when clipping THD at any point is detected.

11)NETWORK 100MB ACTIVITY

a)The Activity LED indicates data activity on the network line.
