1. PEAK/SIGNAL LED: This LED will illuminate green when a signal is present at the High or Low Z inputs. When the signal nears clipping, the LED will illuminate red. (See Gain control, #8.)

2. HIGH: Use this control to adjust the high frequency level for the channel. This control allows for 15dB of cut or boost at

12kHz.

3. MID: Use this control to adjust the midrange frequency level for the channel. This control allows for 15dB of cut or boost at 2.5kHz.

4. LOW: Use this control to adjust the low frequency level for the channel. This control allows for 15dB of cut or boost at

80Hz.

5. MON: Use this control to set the amount of the channel’s signal sent to the monitors.

6. EFFECT: Use this control to set the amount of internal DSP effect (or external effects, if used) to be applied to the channel.

7. LEVEL: Use this control to set the channel’s output signal level.

8. GAIN: Use this control to set the input signal level for the channel. Adjust this control so the peak/signal LED (#1) flashes red on strong signal peaks.

9. PAD: Use this switch to accommodate “hot” input signals.

(Signals too strong to allow a useful setting of the gain control without causing the peak/signal LED to glow red.)

Depress this switch to engage the 20dB pad, thereby reducing the input signal’s level to a more useable range.

10. HIGH Z INPUT: The signal output from a high impedance microphone or a line level signal (such as an instrument, rhythm machine, tape deck, etc.) may be connected here by means of a shielded cable terminated with a male 1/4” plug.

Tip = “+,” ring = “–,” and sleeve = shield.

11. LOW Z INPUT: The signal output from a low impedance microphone or a low impedance line level signal (such as a line out signal from an instrument amplifier) may be connected here by means of a shielded cable terminated with a male XLR plug. Pin 2 = “+,” pin 3 = “–,” and pin 1 = shield.

12. PEAK/SIGNAL LED: This LED will illuminate green when a signal is present at the High or Low Z inputs.

When the signal nears clipping, the LED will illuminate red. (See Gain control, #19.)

13. HIGH: Use this control to adjust the high frequency level for the channel. This control allows for 15dB of cut or boost at 12kHz.

14. MID: Use this control to adjust the midrange frequency level for the channel. This control allows for

15dB of cut or boost at 2.5kHz.

15. LOW: Use this control to adjust the low frequency level for the channel. This control allows for 15dB of cut or boost at 80Hz.

16. MON: Use this control to set the amount of the channel’s signal sent to the monitors.

17. EFFECT: Use this control to set the amount of internal DSP effect (or external effects, if used) to be applied to the channel.

18. LEVEL: Use this control to set the channel’s output signal level.

19. GAIN: Use this control to set the input signal level for the channel. Adjust this control so the peak/signal

LED (#12) flashes red on strong signal peaks.

20. LINE 1/LINE 2 INPUTS: The signal output from a stereo source (such as a stereo instrument, rhythm machine, tape deck, etc.) may be connected here by means of a pair of shielded cables, each terminated with a male 1/4” plug. Tip = “+,” ring = “–,” and sleeve

= shield. The left and right signals are summed internally to become a mono signal – without the need for external summing devices or adapter cables.

21. MIC INPUT: The signal output from a low impedance microphone or a low impedance line level signal

(such as a line out signal from an instrument amplifier) may be connected here by means of a shielded cable terminated with a male XLR plug. Pin 2 = “+,” pin 3 = “–,” and pin 1 = shield.

22,27. GRAPHIC EQ’S: These seven band graphic equalizers allow customization and shaping of the output signals to match room acoustics and enhance the sound. Use the selector switch (#25) to determine where the equalization will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals.

23,28. LED METERS/LIMITER INDICATORS: These LED meters monitor the output signal levels for either the main and monitor output signals, or the main 1 and main 2 output signals (dependent on the setting of the selector switch, #25). The red LED’s illuminate when the internal limiter is engaged to prevent the signal from being clipped. (Clipping results in overdrive distortion and should be avoided.) If the limiter LED’s flash continuously or remain on constantly during use, reduce the output signal levels until they flash only on strong signal peaks.

24,29. EFFECTS RETURNS: Use these controls to adjust the magnitude of the effects applied to the output signals. Use the selector switch (#25) to determine where the effects will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals.

25. MAIN/MONITOR / MAIN1/MAIN 2: Use this switch to select whether the graphic EQ’s, LED meters, and master level controls are assigned to the Main and Monitor outputs (switch in the out position) or to the Main 1 and Main 2 outputs (switch depressed.

When this switch is in the out position, the Main/Main 1 graphic

EQ (#27) controls the signal to power amp #1, the output of which is connected to the Main Output jack (#44). Also, the

Monitor/Main 2 graphic EQ (#22) controls the signal to power amp #2, the output of which is connected to the Monitor Output jack (#43).

When this switch is depressed, the Main/Main 1 graphic EQ

(#27) controls the signal to power amp #1, the output of which is connected to the Main 1 Speaker Output jacks (#46). Also, the

Monitor/Main 2 graphic EQ (#22) controls the signal to power amp #2, the output of which is connected to the Main 2 Speaker

Output jacks (#46).

30. EFFECTS SEND: Use this control to set the overall signal level sent to the internal DSP or external effects (if used).

31. AUX IN: Use this control to set the input signal level of the aux in jack (#40).

32. TAPE IN: Use this control to set the input signal level of the tape in jacks (#41).

34. POWER LED: This LED illuminates when the mixer is on.

35. PHANTOM +48V: This switch, when depressed, applies +48 volts DC to pins 2 and 3 of each channel’s XLR input jacks. This allows use of microphones which require a source of phantom power for proper operation. (Mics not requiring phantom power will not be affected by the presence of the DC voltage.) The adjacent LED illuminates when the phantom power is on.

36. DSP SELECTORS: Use these switches to select the type of digital signal processing effect to be applied – vocal, large hall, and small hall are reverberation effects; delay is a digital delay effect.

37. DSP ON: Use this switch to activate the internal digital signal processor. When this switch is depressed, the selected DSP effect is activated.

38. EFFECTS SEND: Use this jack to send a signal to an external effects device. The signal level at this jack is set by the effects send control (#30).

39. FOOTSWITCH: Use this jack to connect a footswitch for remote on/off control of the DSP and external effects device.

The footswitch must be a normally open, momentary type such as the Crate model #FSIU. The wiring for the footswitch is as shown:

40. AUX IN: Use this jack as the return jack when using an external effects device, or to feed another mixer’s signal into the

PX700DLX/PX900DLX. This jack is post-input channel, pre-eq, and pre-power amp.

41. TAPE IN: Use these jacks to connect the outputs of a tape deck or CD player to the mixer. The playback signal level is set by the tape in level control (#32).

42. TAPE OUT: Use these jacks to connect the mixer to a tape recorder. These jacks are is post-eq, pre-master, and their signal level is determined by the channel level controls.

43. MONITOR OUT: Use this jack to send a line level, monitor mix signal to the power amplifier you are using for your monitor speakers.

44. MAIN OUT: Use this jack to send a line level, main mix signal to an external power amplifier (if used), a recording console, or to the aux in jack of another PX700DLX/PX900DLX.
