NOTE: Before plugging in to a power receptacle, make sure that voltage of your P A-PRO 900 is the same voltage as your local AC mains voltage. The P A-PRO 900 power input setting is factor y set. 2. FUSE HOUSING – Houses the fuse. T o r[...]

15 CHANNEL STRIPS The six ver tical channel strips contain all the individual controls for each channel. Each channel strip works independently of each other , and adjusts only the signal plugged into the jacks below it. Note: If the optional wireless modules are installed, CH 1-4 control strips can adjust the signal from the wireless microphones a[...]

16 P A TCH BA Y MIC/LINE (CH 1-4) The MIC/LINE inputs are for connecting microphones, instruments, or line-level output signals. Once the devices are connected, the signals can be customized using the individual channel strips, and fur ther controlled using the DSP , EQ and main system controls. For each of the channels 1-4, it is impor tant to not[...]

17 COMPRESSOR (CH.1-4) Channels 1-4 have on-board compression available for preventing unwanted distor tion in the audio signal. The compressor works by setting a threshold level with the threshold knob. Once a signal level exceeds that threshold, the signal is automatically compressed. Compression is very useful when the mic/line signal is ver y d[...]

21 33. +48V PHANTOM POWER – This button toggles phantom power to all the XLR microphone jacks. Enabling phantom power sends low current DC voltage to a microphone’ s electronics through the same cable that carries the audio signal. Most professional condenser microphones require phantom power . There are some semi-pro microphones that use a bat[...]

22 Master Out Panel The master out panel is where you make output connections to external devices such as mixers, amplifi ers, powered speakers, headphones, recording devices, etc. All the signals from these jacks are line-level, meaning that they are not powered by the internal amplifi er , and are suited for connection to line-level inputs. 38.[...]

23 SDR-3 RECORDER (optional accessory) Use the optional SDR-3 (if installed) to capture audio direct to SD card. Once recorded, the audio can then be routed to either CH 7-8 or the MAIN mix for immediate playback. Of course, you can also remove the SD card and transfer the MP3 fi les to your computer for fur ther editing and processing. 1. REC VOL[...]

24 9. SD CARD SLOT – Inser t your SD card into this slot. The SDR-3 will not record without an SD card in this slot. 10. REC LEVEL LEDs – These LEDs visually represent the gain level of the signal being recorded. There are fi ve green LEDs and two red LEDs. An optimal recording level will illuminate all the green LEDs with minimal activity on [...]

25 Optional Accessories UHF W ireless Channels (optional accessory) Y ou can add up to four UHF wireless microphone modules (sold separately) to use with the P A-PRO 900.
