This mono unbalanced 1/4” jack outputs the channel signals which can be adjusted by the Effects Send Controls (7 & 12).

(28) EFFECTS RETURN INPUT

This mono unbalanced 1/4” jack enables convenient inputs to the Effects Channel. If you connect a signal to the return jacks, the signal will be routed to the effects Channel Volume Control (11).

Plugging into either the Effects Send Output (27) or Effects Return Input (28) jacks will automatically disable the internal Echo Effects.

(29) SUBMIX 1 & 2 SEND/RETURN INSERTS

These 1/4” TRS insert jacks can be used to send out the Submix signals to an external device and return the signals back via the same jack. They are pre-Sub 1 & 2 fader and allow for routing the signal through external devices such as equalizers, compressors, or effects units. Insert cables must be used for these connections. The wiring for the insert jacks is Tip = Send,

(30) SUBMIX 1 & 2 OUTPUTS

These 1/4” jacks output the Submix 1 & 2 unbalanced line level signals.

(31) MAIN LEFT & RIGHT SEND/RETURN INSERTS

These 1/4” TRS insert jacks can be used to send out the Main Left & Right signals to an external device and return the signals via the same jack. They are pre-Main Left & Right Volume fader and allow for routing the signal through external devices such as equalizers, compressors, or effects units. Insert cables must be used for these connections. The wiring for the insert jacks is Tip = Send, Ring = Return.

(32) MAIN LEFT & RIGHT OUTPUTS

These 1/4” jacks output unbalanced line level signals from the Main Left and Right volume faders.

(33) LOW-PASS LEFT & RIGHT OUTPUTS

These 1/4” jacks output unbalanced line level signals that have been filtered through a Low Pass filter. This output is perfect for feeding directly to an amplifier that powers a subwoofer speaker or to a powered subwoofer with no crossover necessary. The frequency response is 30Hz - 150Hz (-6dB) with a -12dB roll-off point at 250Hz. These signals are post Main Left & Right faders.

(34) RECORD LEFT & RIGHT OUTPUTS

These 1/4” jacks output unbalanced line level signals from the Left and Right bus. These signals are pre Main Left & Right faders.

(35)POWER ON/OFF SWITCH

Use this rocker switch to turn the unit on and off.

(36) STEREO SPEAKER OUTPUTS

These Left & Right 1/4” speaker outputs can each deliver up to 210W RMS to 4 ohms loads or 150W RMS to 8 ohms loads with both channels driven simultaneously.

[Caution: Make sure that the speaker, connectors and wiring can handle the rated output power to avoid damage. Note that prolonged use at levels above clipping can drive the amplifier into thermal runaway and damage the internal amplifier and speaker, so care must be taken to not overload the amplifier. Never use less than 4 ohms total impedance for either channel as this can also cause the amplifier to overheat and create thermal runaway.]

(37) POWER CONNECTOR

The IEC jack is used to connect the power cord to the AC Power Source.

[Caution: Never remove the center grounding pin as this can cause a serious safety hazard and will immediately void your warranty.]

(38) FUSE COMPARTMENT

Replace with only the same type fuse. If the fuse blows continuously, have the unit serviced by qualified personnel. The PMX-420 powered mixer uses 20mm glass tube Fast Blow fuses: 5A 250V for 115VAC, 2.5A 250V for 230VAC.

(39) AC VOLTAGE SELECTOR SWITCH

Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V (60Hz) or ~230V (50Hz).
