Operating instructions

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. 5-8 via the ¼” jacks. Note that CH.

5/6 and 7/8 will be controlled together by the channel

strips. If connecting a single mono signal to either CH. 5/6

or CH. 7/8, connect to the L(MONO) jack.

For power output, this example shows PA-PRO 900

conﬁ gured for MAIN L/R+MONITOR output. A pair of

passive speakers is powered by the MAIN L./R speaker

connector. A passive monitor speaker is powered by the

MONITOR speaker connector. An additional set of powered

speakers can be connected to the MAIN OUT jacks on the

front panel.

Recording can be done either with an optional SDR-3 SD

recorder, or to an external recording device connected to

the RCA record out jacks on the front panel.

NOTES:

If connecting a single mono signal to either CH. 5/6 or CH.

7/8, connect to the L(MONO) jack.

The optional UHF wireless mic channels require the SOURCE

SELECT switch to be set to UHF.

POWER AMP ASSIGN switch must be best to MAIN L/

R+MONITOR
