Manual-6PAGINGThe HOUSE PAGE Input provides a means to automatically interrupt all program material, and broadcastemergency messages at a preset level.The HOUSE PAGE jack is a balanced 3-pin Euroblock. The Input is line-level with a maximum signallevel of +20 dB. When an input signal greater than –20 dBu is sensed, HOUSE and BOOTH levels automati-cally attenuate 40 dB and the HOUSE PAGE signal routes to both HOUSE and BOOTH Outputs. TheHOUSE PAGE INPUT LEVEL is set independent of HOUSE and BOOTH LEVEL settings. This controlis a recessed, screw driver adjusted control located on the rear panel to prevent tampering after installation.MIC INPUTSBoth MAIN and AUX MIC Inputs operate separately but identically.The maximum input and output levels for the EFFECTS loops is +20dBu.MAIN & AUX MIC INPUTS are balanced with combination XLR /¼" TRS jacks. The maximum input level is +4 dBu. The MAIN MICGAIN range is +15 dB to +60 dB, and has a PHANTOM PWR switch toselect +12 volt phantom power. The AUX MIC is switchable MIC orLINE level. It has a GAIN control range of +30 to +60 dB in MIC mode.In LINE mode, the maximum input is +20 dBu with a GAIN control range of 0 to +30 dB. Use the GAIN control in conjunc-tion with the OL indicator (see below) to set the correct gain.MAIN & AUX MIC EFFECTS SENDS are unbalanced mono Outputs on ¼" Tip/Sleeve jacks. This Output is used forexternal processing, including EQ, dynamic range control, special effects boxes, etc. The MAIN or AUX MIC signals arealways present on each of these respective Outputs.MAIN & AUX MIC EFFECTS RETURN are unbalanced mono Inputs on ¼" Tip/Sleeve jacks. This Input receives the signal from an external processor. This is a switch-ing jack—if no external connection is made to the jack, the EFFECTS SEND signal isinternally connected to it's own EFFECTS RETURN.MAIN & AUX MIC LEVELS are full-range faders used to set the desired level ofeach mic.OL (overload) indicators light 3 dB before clipping. The signal level is monitoredboth pre- and post-tone control. Adjust the rear panel Input GAIN while speaking loudlyinto the mic so that the indicator remains off.HI, MID and LOW controls provide independent tone control for each of the MICS.The EFFECTS switch engages the MIC EFFECTS loop. As stated above, if anexternal connection is not made to the RETURN jack, the MIC EFFECTS switch has noeffect.The ENGAGE switch routes the Mic signal to both MASTER HOUSE and BOOTH. Inthe ENGAGE position, the blue on indicator lights and the BOOTH level attenuates 12 dB.LIGHT TRIGGER OUTPUTThe LIGHT TRIGGER OUTPUT is a mono balanced output on a ¼" TRS jack. The output LEVEL rangeof the screwdriver adjustment is off to +6 dB. This Output drives a lighting control box or any other equipmentrequiring a mono MASTER signal. Maximum Output signal level on this jack is +20 dBu.
