Introduction Features The ProMatrix units have the following features: • 2 Lo-Z balanced Mic inputs (Mic A is female XLR, Mic B is screw termi- nals). Mic B can be configured as a 600-Ohm transformer balanced input for telephone paging applications. • Automatic level control for Mic inputs. • Choice of microphone precedence activation (VOX, N[...]

Quick Start This Quick Start section is intended to assist you in getting the ProMatrix unit up and running quickly so that you can become familiar with it. Important: Do not place any objects directly on top of the unit. Leave at least 2 inches of space above the unit to assure prop- er ventilation. When locating the PM-3180, be sure to leave at l[...]

Be sure that the voltage select switch is set correctly . Connect the power cord to the AC LINE INPUT 3. Connect outputs. For the PM-3000 , connect the correct style output (balanced [...]

Quick Start Factory Programmed Configuration When the ProMatrix unit is first powered up, the factory default settings are loaded. The factory default priority table is listed below . If you want to change any of these priority levels, you will have to use the ASSIGNMENT function in the programming mode. See the Programming section of these instruc[...]

Quick Start Basic Operation This section will show you how to: • Apply power to the unit • Understand the Control Panel (See page 12 for full description) • Select which channel the control panel affects • Change volume • Change Bass and T reble response • Manually select an input or allow priority-based switching • Adjust Aux Input T[...]

Quick Start T o Control V olume Note: Changing any of the volume, bass or treble levels will effect all inputs associated with that amp/channel channel. T urning up the volume for the current amp/channel will cause other inputs assigned to that amp/channel to play louder when they become active. Likewise for bass and treble. Be sure VOL is the curr[...]

Quick Start T o Select a Specific Input The ProMatrix unit is normally set to monitor input activity and, based on the default or installer-created priority table, automatically switches the proper input for each amp/channel. Y ou can override the priority switching feature of any amp/channel to select a specific input to be on continuously . 1. Pr[...]

Quick Start Aux Input T rim Adjustment By adjusting the T rim controls as follows, inputs with different signal levels are set approximately equal within the ProMatrix unit. Important: Y ou must properly set the Aux Input Trim Controls. Improperly adjusted trims can result in high distortion levels, poor volume balance between different inputs or f[...]

Push-to-talk switch p[...]

User Operation The ProMatrix Control Panel The control panel is the interface between the user and the unit functions. Since there are three channels (amp or preamp) and only one control panel, the ProMatrix uses selector buttons, indicators and an alphanumeric display to provide control of the overall functions. The information below will famil- i[...]

User Operation T o Control V olume, Bass or T reble Note: Changing any of the volume, bass or treble levels will effect all inputs associated with that amplifier channel. T urning up the volume for the current amplifier will cause other inputs to play louder when they become active. Likewise for bass and treble. 1. T o control volume, bass, or treb[...]

User Operation the current input was lowered by . This is because the levels set by the user are temporary and the ProMatrix always strives to maintain volume differences set by the preset programming. T ypically , this will only occur when the inputs or limits are set vastly different for the inputs assigned to an amp channel. The same applies to [...]

Programming Enter Programming Mode The programming mode lets the installer custom configure the ProMatrix unit. The installer uses the programming buttons on the front panel or the infrared remote controller . Programming Buttons 1. Press PROG. The LED next to the button lights and the display shows 3 dashes.
