LOCATION: The appliance should be installed in a stable location.
NON-USE PERIODS: The power cord of the appliance should be unplugged from the

outlet when left unused for a long period of time.

GROUNDING OR POLARIZATION:

• If this product is equipped with a polarized alternating current line plug (a plug
having one blade wider than the other), it will fit into the outlet only one way. This
is a safety feature. If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose of the polarized
plug.

• If this product is equipped with a three-wire grounding type plug, a plug having
a third (grounding) pin, it will only fit into a grounding type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact your elec­trician to replace your obsolete outlet. Do not defeat the safety purpose of the
grounding type plug.

POWER-CORD PROTECTION: Power-supply cords should be routed so that they

are not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and the
point where they exit from the product.

OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is con-

nected to the product, be sure the antenna or cable system is grounded so as to
provide some protection against voltage surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/NFPA 70, provides information with

regard to proper grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of grounding conductors, location
of antenna-discharge unit, connection to grounding electrodes, and requirements
for the grounding electrode. See Figure B.

LIGHTENING: For added protection for this product during a lightening storm, or

when it is left unattended and unused for long periods of time, unplug it from the

extensive work by a qualified technician to restore the product to its normal oper­ation.

• If the product has been dropped or damaged in any way.

• When the product exhibits a distinct change in performance, this indicates a
need for service.

REPLACEMENT PARTS: When replacement parts are required, be sure the service

technician has used replacement parts specified by the manufacturer or have the
same characteristics as the original part. Unauthorized substitutions may result in
fire, electric shock, or other hazards.

SAFETY CHECK: Upon completion of any service or repairs to this product, ask the

service technician to perform safety checks to determine that the product is in
proper operating condition.

1. All instructions should be read before using this equipment.

2. To reduce the risk of electrical shock, do not open the unit.
Please refer all servicing needs to a Gemini-qualified service
technician.

3. Do not expose this unit to direct sunlight or a heat source
such as a radiator or stove.

4. This unit should be cleaned only with a damp cloth. Avoid sol­vents or other cleaning detergents.

5. When moving this equipment it should be placed in its origi­nal carton and packaging. This will reduce the risk of damage
during transit.

6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

7. DO NOT USE SPRAY CLEANERS OR LUBRICANTS ON
CONTROLS, SURFACES OR SWITCHES.

1. Ensure that the POWER SWITCH (1) is in the OFF position
prior to making any connections. This unit comes with a power
cord. Plug into the rear panel POWER CORD (2) jack before
plugging it into a proper power source.

2. The PS-424x has 2 stereo outputs located on the rear panel:

- The MASTER RCA OUTPUT (3) connects the mixer to your

main amplifier using standard audio cables with RCA-type con­nectors.

The REC (4) output jacks can be used to connect the mixer to

the record input of your recording unit, thus enabling you to
record your mix with RCA cables.

4. Headphones may be plugged into the front panel-mounted
HEADPHONE (5) ¼" jack.

5. Microphones may be plugged into the rear panel-mounted
MICROPHONE (6) ¼" jack.

6. The PS-424x has 2 CONVERTIBLE PHONO/LINE (PH/LN)

RCA INPUTS (7) located on the rear panel on either side of the
RCA INPUTS. Facing the rear panel, the convertible RCA input

on your right is for PH 1/LN 1 (7). The convertible RCA input on
your left is for PH 3/ LN 5 (7). Using the PH/LN CONVERTERS
(8), located just below each input, you may convert the PH to LN
and vice versa. Plug the RCA's from your playable medium into
each input to be connected to their respective CHANNELS
(CH). When the PH/LN CONVERTERS (8) are set to Phono,
the CONVERTIBLE PHONO/LINE (PH/LN) RCA INPUTS (7)
only accept turntables with a magnetic cartridge. The STEREO

LN INPUTS (7) only accept line level inputs such as a CD, DAT,
Mini Disc, etc and require the proper switch setting.

7. When using (a) turntable(s), you will need to ground the RCA
cable(s) by screwing in the grounding fork(s) to the GROUND-
ING SCREW (9) located in the rear panel of the PS-424x mixer.
Attach each PH ground line to the GROUND THUMB SCREW
(9). This is located directly above the REAR PANEL MICRO-

PHONE JACK (6).

NOTE: WHEN USING TURNTABLES, NOT ATTACHING A GROUND MAY
CAUSE A SYSTEM "HUM."

1. Once all of your connections have been made in the rear
panel, turn on the mixer by pressing the POWER SWITCH (1).

2. CH 1: To bring this channel into program output (PGM), you
must first decide which line will be in use. Use the LN SWITCH
(10) to toggle from PH 1/LN 1 to LN 2 on this channel. Once
you've selected the proper line, slowly raise the CH 1 SLIDE
CONTROL (11) to a comfortable level. You can further modify
the sound output of this channel by adjusting the rotary GAIN
(12), HIGH (13), MID (14), LOW (15) controls located above the
CH 1 SLIDE CONTROL (11).

3. CH 2: To bring this channel into PGM, you must first decide
which line will be in use. Use the LN SWITCH (10) to toggle from
PH 2/LN 3 to LN 4 on this channel. Once you've selected the
proper line, slowly raise the CH 2 SLIDE CONTROL (11) to a
comfortable level. You can further modify the sound output of
this channel by adjusting the rotary GAIN (12), HIGH (13), MID
(14), LOW (15) controls located above the CH 2 SLIDE CON-

TROL (11).

NOTE: FOR OPTIMAL PERFORMANCE, BEGIN PROGRAM MIX WITH
ROTARY GAIN (12) CONTROLS SET TO MINIMUM (ROTATE IT COUNTER­CLOCKWISE TO THE COUNTER CLOCKWISE POSITION). MAKE ALL
ADJUSTMENTS IN SOUND OUTPUT WITH THE USE OF YOUR CHANNEL
SLIDE CONTROLS AND MASTER (21) VOLUME ROTARY CONTROLS. THIS
WILL PREVENT SIGNAL OVERLOAD AND DECREASE DISTORTION. ONCE YOU
HAVE MODIFIED YOUR SOUND AND WOULD LIKE TO INCREASE THE OUTPUT OF
YOUR SOUND, THEN YOU MAY ADJUST THE ROTARY GAIN CONTROL IF
NEEDED.

5. CUE: By connecting a set of headphones to the HEAD­PHONE (5) jack, you can monitor any or all channels.
