PM62S/PM82S/PM82T Powered Mixers Features: The Input Channels: • Peak LEDs for optimum level settings • Three bands of equalization • Monitor, effects, and pan controls • Output level controls • Pad switch (mono channels) to accommodate “hot” signals • XLR balanced low impedance mic input jacks • 1/4” balanced high-Z line input jacks The Master Section: • Tri-Power! Three internal power amplifiers (PM82T only) - one for the monitor, two for the main speaker outputs • Two internal power amplifiers (PM62S,
PM62S/PM82S/PM82T Powered Mixers The Mono Input Channels: 1 2 3 4 1. PEAK LED: This LED illuminates when the input signal nears clipping. During normal operation, this LED will flash on strong signal peaks. If the LED remains illuminated, depress the Pad switch (#9) and/or reduce the level of the signal connected to the input jack (#10,11). 2. HIGH: Use this control to adjust the high frequency level for the channel. 3. MID: Use this control to adjust the midrange frequency level for the channel. 4.
PM62S/PM82S/PM82T Powered Mixers The Stereo Input Channels: 12 13 14 15 12. PEAK LED: This LED illuminates when the input signal nears clipping. During normal operation, this LED will flash on strong signal peaks. If the LED remains illuminated, reduce the level of the signal connected to the input jack (#20,21). 13. HIGH: Use this control to adjust the high frequency level for the channel. 14. MID: Use this control to adjust the midrange frequency level for the channel. 15.
PM62S/PM82S/PM82T Powered Mixers The Master Section: 22. DSP ON: This switch, when depressed, activates the internal digital signal processor. 23. PROGRAM: Use this rotary switch to select the desired digital effect. The name of the selected effect illuminates on the DSP display panel (located above the On switch, #22). A brief description of the DSP effects is provided on page 9. 25 24 26 27 25.
PM62S/PM82S/PM82T Powered Mixers The Master Section (con’t): 31. LIMITER/LED METER: The mixer employs internal limiter circuits to prevent overdrive distortion from being reproduced by the amplifiers. The Limiter LEDs illuminate when either of the main amplifiers’ internal limiter circuits are activated. The two sets of five-step LED displays directly below the Limiter LEDs indicate the levels of the left and right main’s output signal. 32.
