Hookup Diagrams House of Worship/Full Band For this example, there are four microphones connected to channels 1-4. These microphones can either be the optional UHF wireless channels, low-impedance corded microphones, or high-impedance corded microphones. Musical instruments are connected to channels 5-8. Note that when connecting instruments to channels 5-8, the LEVEL control will need to be set rather high due to the lower signal level from instrument output.

Hookup Diagrams DJ For this example we have two microphones in use on channels 1 and 2; one for the DJ, the other as a backup or guest speaker. There is a line-out from a DJ mixer connected to CH. 5/6 to serve as the main music source. For additional music needs, either a laptop computer or MP3 player is connected to CH. 7/8. You can have a sonic enhancer or other effect device connected to the CH. 5/6 effect loops to apply desired effects to the source music.

Hookup Diagrams Public Address/Presentation For this set up, there are four microphones connected to channels 1-4. These microphones can be either the optional UHF wireless channels, low-impedance corded microphones, or high-impedance corded microphones. Source music devices are connected to channels 5-8. Note that when connecting stereo source music devices to either CH. 5/6 or CH. 7/8, you can either connect via 1/8” mini-jack, RCA or L/R ¼”. If connecting mono source audio devices, connect them the CH.
Rear Panel Features � � � � � � � � �� � �� � � � REAR PANEL FEATURES 1. POWER CONNECTOR – Connect the supplied 3-prong power cord to this connector. 1a. NOTE: Before plugging in to a power receptacle, make sure that voltage of your PA-PRO 900 is the same voltage as your local AC mains voltage. The PA-PRO 900 power input setting is factory set. 2. FUSE HOUSING – Houses the fuse. To remove the fuse, unscrew the fuse cap counter-clockwise. In the case of a blown fuse, replace once only.
Front Panel Features 3. DSP/REV AUX – These controls adjust the amount of DSP effects applied individually to channels 1-8. This allows you to set more DSP effects to the microphone channels, and less to channels with instruments connected. These controls only adjust the amount of DSP applied to each channel; to set the individual parameters of the DSP effects, refer to the DSP REV CONTROL panel control.
� �� � Front Panel Features � �� � �� � �� PATCH BAY 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 further controlled using the DSP, EQ and main system controls.
Front Panel Features �� �� COMPRESSOR (CH.1-4) Channels 1-4 have on-board compression available for preventing unwanted distortion 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 very dynamic (fluctuating from very low to high levels) and has the potential to overload the inputs.
Front Panel Features 18. ECHO DELAY – This control is used to adjust the length of time between each echo repetition. When set to minimum, the echo repetitions will occur rapidly, with little to no time between them. As this control is turned clockwise, the time between each repetition will increase. 19. DSP ON/OFF – Use this control to quickly enable or disable all DSP effects. This can be used to switch to a “dry” signal for DJ or speaker announcements.
Front Panel Features �� �� �� �� �� �� � � � � �� 25. MAIN L, R GRAPHIC EQ – This 7-band graphic EQ is used to customize the sound of the MAIN L, R mix output. This EQ section affects the signals found in the MAIN (XLR), headphone, line-level, and speaker-level jacks (when configured to MAIN L, R). The 7 slide controls each represent a frequency band: 125, 250, 500, 1K, 2K, 4K, and 8K. Each of the slide controls adjusts the audio level of its particular frequency with up to a 12dB boost or cut.
�� �� Front Panel Features �� �� � � �� � �� �� �� �� �� � 29. MONITOR GRAPHIC EQ – This 7-band graphic EQ is used to customize the sound of the MONITOR mix output. This EQ section affects the signals found in the MONITOR (1/4”) jack and the speaker-level jack (when configured to MAIN L, R+MONITOR). The 7 slide controls each represent a frequency band: 125, 250, 500, 1K, 2K, 4K, and 8K. Each of the slide controls adjusts the audio level of its particular frequency with up to a 12dB boost or cut.
Front Panel Features 34. POWER AMP ASSIGN – This switch lets you choose which signals will be routed to the PA-PRO 900’s power amplifier. This provides flexibility in how the PA-PRO 900’s internal power amplifier can be utilized. � To set the POWER AMP ASSIGN switch, use a small screwdriver to maneuver the switch to the desired position. �� Set this switch to MAIN L,R for straight stereo playback.
�� �� Front Panel Features �� �� �� �� �� Master Out Panel The master out panel is where you make output connections to external devices such as mixers, amplifiers, powered speakers, headphones, recording devices, etc. All the signals from these jacks are line-level, meaning that they are not powered by the internal amplifier, and are suited for connection to line-level inputs. 38. MAIN OUT – These stereo jacks route balanced line-level signals of the MAIN mix to external devices.
Optional Accessories � � � � � ����� ��������� ���� ���� ��� �� ��� ��� ���� ����� �� ������������������� � � � 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 files to your computer for further editing and processing. 1.
Optional Accessories 9. SD CARD SLOT – Insert 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 five green LEDs and two red LEDs. An optimal recording level will illuminate all the green LEDs with minimal activity on the red LEDs. 11. SD PLAYBACK ROUTE – This button will direct the audio from the SD player to either the MAIN(L,R) output, or to CH 7/8.
Optional Accessories � � � � � UHF Wireless Channels (optional accessory) You can add up to four UHF wireless microphone modules (sold separately) to use with the PA-PRO 900. Each port on the rear panel corresponds to a mic channel on the front panel. Adjustments made to the channel strips on the front panel will adjust the audio from the wireless microphones. Channel 1 on the front panel is tied to Channel 1 on the rear panel, Channel 2 to Channel 2 and so forth.
