Nady Systems PMX-420 - Manual (Page 8)

(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).
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,
Ring = Return.
(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.
