(14) ECHO EFFECTS DISPLAY

This numeric LED display will indicate which of the 16 echo presets has been selected (0 - F).

(15) ECHO EFFECTS REPEAT CONTROL

This control adjusts the number of repeats and feedback/depth of the echo effect. Turning the control clockwise sets the repeats to maximum for lengthy stadium echoes or plate effects. Turning the control counter-clockwise sets less repeats for doubling effects.

The Effects Channel Pan Control (8), Submix 1 & 2 Select Button (9), PFL Button (10), and Channel Volume Control (11) all operate same as the other channels on the internal Echo Effects signal or the Effects Return signal.

(16) SUBMIX 1 & 2 VOLUME FADERS

These faders adjust the level of the Submix 1 & 2 signals that are sent to the Submix 1 & 2 Outputs (30). These faders are post Submix 1 & 2 Send/Return Inserts (29) and will control any signal returning to the PMX-420 via those jacks. The Submix signal can also be selected for the Headphone Output (26) for easy monitoring. The Submix can be a very useful feature if used effectively The Submix can be used as a mixing aid both live and in the studio; for example, to combine certain signals to send to a monitor feed, external power amp, or to an external effects processor. This submix can also be added to the Main/Master mix by depressing the Submix to L-R

Enable Buttons (17).

These adjust the final level of the Master Left & (28) Right signals, that are sent to the Main Left &

Right (32), Record (34), Low-Pass (33), Headphone (26), and Speaker Stereo Outputs (36). These faders are post Main Left & Right Send/Return Inserts (31) and will affect any signal returning to the PMX-420 via those jacks.

(20) LED LEVEL SELECT SWITCH

This switch is used to select which signals will illuminate the Dual LED Bargraph Meter (21). Main Stereo Left & Right signals are displayed when set to L - R. When set to S1 - S2, Submix 1 is displayed on the left and Submix 2 is displayed on the right. When set to Effects - PFL, the effects level is displayed on the left bargraph and the PFL level is displayed on the right bargraph.

(21) DUAL LED BARGRAPH METER

These 5-stage dual LED meters will display the relative output level of either the Main Left and Right, Submix 1 & 2, or Effects and PFL signals depending on the LED Level Select switch. They

can be used to maintain proper levels. When set to Main Left & Right, the top red Peak LED will light when the powered output signal is just below clipping. It is acceptable if the red LED lights occasionally. If the red LED lights more than occasionally, you should turn down the Main Left & Right Volume Faders (19) to avoid audible distortion and clipping, which can cause damage to your speakers and even the internal amplifier.

[Caution: Prolonged use at levels above clipping can cause damage to your speakers and even the internal amplifier. Carefully monitor the bargraph meter to avoid prolonged clipping.]

(22) HEADPHONE SELECT SWITCH

This switch is used to set which signal will be sent to the Headphones Output (26). Main Stereo Left & Right signals are sent when set to L - R. When set to S1 - S2, Submix 1 is heard on the left and Submix 2 on the right. The signal of any channel with its PFL Button depressed is heard when the switch is set to PFL.
