Isolated Auxiliary Output* This sends a transformer isolated mono signal for a music-on-hold system, or for a separate mono auxiliary zone. The +/- outputs are 600 Ohm transformer isolated so that they can interface to another system (telephone or remote amplifier) without having undesirable ground interaction.

5.0 Knowing Your Mixer 5.1 Source What is a Source? This is a line-level input signal such as programmed music, CD player, VCR/DVD, satellite feed, tape player, radio, message repeater, or juke box.

6.0 Setup 6.1 Determining Source Priorities Determining the hierarchy of your sources is easier than it sounds. Generally it follows this order: 1. Emergency/Alarm (Direct Input with MUSIC MUTE engaged) 2. Pages (Paging Mic) 3. Prerecorded announcements (or another source into SOURCE 1 with Priority engaged). 4.
6.5 Using Subwoofer Crossover When the XOVR switch is engaged, the main speakers are high passed at 125 Hz and the subwoofer outputs are low-passed at 125 Hz (both with a slope of 24 dB per octave), forming a full subwoofer crossover.
6.8 Setting Up LevelGuard™ To set up LevelGuard™ begin by turning the LevelGuard™ trim pot to 12:00. Use this as your “base- line” setting. Now turn up the Source volume to the level desired for a particular zone. Check the Lev- elGuard™...
