1) ENABLE ALT PRESET button |
| |
a) Momentary, Enables or Disables the selected function. | �� | |
Factory ALT Preset: | ||
On subwoofer applications, the subwoofer |
| |
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 | � | |
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 | ||
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
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.
