INTRODUCTION

The Memphis Car Audio Studio Series amplifiers offer high quality audio reproduction

for the audiophile and the everyday listener alike. Full Mosfet design and 18dB per

octave crossovers ensure accurate musical reproduction. All models feature fully

variable crossovers with 18dB per octave slopes, allowing you the ability to tailor the

sound to best fit the speakers and your listening preferences.

When combined with the Studio Series Co-Axial, MultiSync Component speakers, and

the Studio Series Subwoofers powered by one of the four Studio ClassD subwoofer amps,

you have a complete mobile reference system. To further enhance your listening

enjoyment, Memphis Car Audio also offers a wide range of signal processors as well.

STANDARD FEATURES FOR ALL 2 AND 4 CHANNEL MODELS

•Brand new for 2003

•2ohm Stereo Stable / 4ohm Mono

•High & Low Level Inputs

•9dB bass boost all models (PR300.2 has variable boost)

•Bridgeable & Tri-Mode Operation

•Fully Variable High & Low Pass Filters

•Protection Circuitry Against Overload, Short Circuit, Thermal, and Reverse Polarity

Bridgeable & Tri-Mode Operation Memphis Car Audio Power Reference amplifiers

can be used in stereo, bridged, or tri-mode operation. Tri-Mode operation means that pair

of speakers is wired in the conventional stereo manner, while a subwoofer is

simultaneously connected to the bridged terminals of the same two channels. This is

useful for simple 2-channel systems that require a subwoofer in addition to the full-range

speakers.

Brand New Design for 2003 Black textured finish heat sink with black chrome trim

and injection molded end plates, and all the features you need!

Platinum finish connections Ensures solid electrical connections that resist corrosion.

Fully Variable High & Low Pass Crossovers Fully variable crossovers promote

installation ease and save the cost of outboard crossovers. Additionally, they may be

used in conjunction with outboard passive or active crossovers, depending on the

complexity required by the system. The 12dB per octave slope offers steep roll-off above

or below the selected frequency.

Protection Circuitry Against Overload, Short Circuit, Thermal, and Reverse These

protection features are designed to protect the amplifier from misuse, as well as from

common causes of amplifier failure.

What does the little green light mean?

•It means that the amplifier is on, and should be working normally. If the light is not

illuminated, then please consult the trouble shooting section of this manual.

INSTALLATION

Professional installation by an authorized Memphis Car Audio dealer is highly

recommended! Otherwise, the performance of your new gear may not be satisfactory. In

the event that you decide to do your own installation, please read and follow this manual

very carefully. Failure to do so may compromise the integrity of this product, your

automobile, and possibly void the product warranty.

Amplifiers are generally mounted in the hatch/trunk area of a car or SUV, and under or

behind the seat of most pick up trucks. Select a location that will provide adequate

ventilation for the amplifier. Avoid mounting the amplifier with the fins facing down.

The fins should be facing up, either vertically or horizontally. Secure the amplifier with

the screws provided.

WARNING!

Before securing the amplifier, inspect the mounting location carefully to ensure that you

do not drill into or damage any electrical, hydraulic, fluid, or fuel lines.

POWER SUPPLY CONNECTIONS

WARNING!

INSTALL THE FUSE AT THE BATTERY LAST!

Use conventional stranded copper wire for all connections. Finish the ends of the wires

at the amp and vehicle connection with the proper size terminals. Poorly made

connections, and /or inadequate wire size will generate excessive heat and may lead to

equipment failure.

The 12 VOLT + connection should be made directly at the positive battery post, using

the wire size recommended below, and fused within 18” of the battery. This fuse is vital,

and is primarily intended to protect the vehicle from damage in case of a dead short. The

fuse value at the battery should be at least the total fuse value of all of the amplifiers

being used.

PR100.2 8 25A

PR150.2 8 40A

PR200.2 8 50A

PR300.2 8 50A

The GROUND connection should be made directly to the chassis of the vehicle, as close

to the amp as possible. Make this connection with the same wire size as used for the 12

Volt + connection. Ensure that all dirt, grease, paint, and coatings are removed from

around the connection to the vehicle chassis. Use of a nut, bolt, and toothed type washer

is recommended for attaching the ground wire to the chassis.

The REMOTE TURN ON terminal should be connected to the source units’ remote turn

on lead or power antenna output wire. When using the power antenna wire, make certain

that this wire does not lose power when any source other than the radio is selected.

SIGNAL INPUT CONNECTIONS

The RCA jack(s) marked ‘IN’ should be connected to the low level outputs of your

source unit or signal processor. High-level (speaker level) inputs are provided as well.

SPEAKER CONNECTIONS

Most speakers have a positive (indicated with a + or colored dot) and negative (indicated

with a -) marking on the terminals. These are used to indicate polarity, and must be

considered when wiring stereo speakers or multiple subwoofers to an amplifier.

Amplifiers also have positive and negative markings on their speaker outputs. These may

be used to correspond or match with the speaker polarity markings to ensure that the

stereo speakers are in-phase with each other. Failure to wire stereo speakers in phase

with one another will result in a loss of bass. All Power Reference amps require

minimum 2ohm impedance in stereo or 4ohms in mono (bridged) mode.

SET UP AND ADJUSTMENT

Gain

The gain control is NOT a volume control. The gain control adjusts the amount of signal

required to drive the amplifier to full output. With the gain at maximum (full clockwise

rotation), less signal voltage is required to drive the amp to full output. With the gain at

minimum (full counter-clockwise rotation), more signal voltage is required to drive the

amp to full output.

High Pass Filter (crossover) or HPF

The high pass crossover, or filter, is designed to remove low frequency information from

a speaker. This is generally used to protect smaller drivers from trying to reproduce low

frequency information that might damage them. The crossover frequency is adjustable

from 40Hz to 400Hz, and uses an 12dB per octave slope. To engage the HPF, simply

slide the switch to the position on the marked HPF. Crossover frequency selection is

made by rotating the dial; clockwise raises the frequency and counter-clockwise lowers

the frequency. Most mid-bass or midrange drivers should be set between 80 and 100Hz,

depending on how high the subwoofer(s) plays. For mid-range drivers that are 5” or

smaller, we suggest setting the high-pass crossover to at least 120Hz. The HPF can also

be combined with passive crossovers on a separate or co-axial speaker set to provide low-

frequency protection to the midrange driver; or to form band-pass filter for a midrange

speaker already using a passive low-pass filter.

Low Pass Filter (crossover) or LPF

The low pass crossover, or filter, is designed to remove high frequency information from

a speaker. This is generally used to prevent mid-bass speakers or subwoofers from trying

to reproduce mid and high frequency information that they are not designed to reproduce.

The crossover frequency is adjustable from 40Hz to 400Hz, and uses an 12dB per octave

slope. To engage the LPF, simply slide the switch to the position on the marked LPF.

Frequency selection is made by rotating the dial; clockwise raises the frequency and

counter-clockwise lowers the frequency. Most subwoofers should be set between 80 and

100Hz, depending on how low the mid-bass or midrange drivers are capable of playing.

Flat-no filter

Sliding the selector switch to this position turns off all crossovers, and allows a full-range

signal to pass. The Flat position should be selected when using outboard electronic

crossovers.

Bass Boost Bass boost on all models is switchblade either on or off. Boost on the 300.2

is variable. Boost should be used with discretion, keeping in mind that electronically

enhanced boost places an additional load on the amplifier and the speakers they are

connected to.

FEATURES AND CONTROLS

TROUBLESHOOTING

Before removing your Amplifier, refer to list below and follow the suggested procedures.

Speakers and their wires should be tested first.

No Output:

a. Confirm that all wires are properly connected.

b. Check in-line and built-in fuses. Both “12V”and “RMT” terminals must have

+12 Volts.

c. Confirm that signal source (Car Radio/Deck, EQ, X-over etc.) is connected and is

supplying output signal.

d. If the Amplifier is hot, refer to section “Ⅳ. PROTECTION CIRCUIT”.

Only One Channel Works:

a. Confirm that speaker wires are properly connected.

b. Check “BALANCE” control on Car Stereo (or signal source) to verify it is at mid-

point.

c. If using RCA Low-Level inputs, reverse the input plugs at the Amplifier

(right to left or vice versa).

If the channel that is silent reverses position, the problem is in the Car Stereo

(EQ, X-over, or other signal source) or connecting cable.

Weak Output

a. Check Input Sensitivity control adjustment.

Noise in Audio

a. If noise is a “whine” that goes up and down with engine speed, confirm that

Amplifier and any other source unit (Radio, EQ, X-over etc.) is properly grounded. Use

unshielded twisted pair RCA cables, and route them away from wiring in the vehicle.

b. A “clicking” or “popping” noise at a rate that follows engine speed is generally

induced by the vehicle’s ignition system. Confirm that the vehicle is equipped with

resistor plugs and plug wires. Or, ignition system may need service. High output

ignition coils can also cause similar interference, which can usually be remedied with

compatible high-performance plug wires.

c. Speaker and input wires should not be routed next to wires that interconnect lights

and other accessories/equipment.

d. If above steps do not improve/clear noise interference, the system should be checked

by your Authorized Memphis Car Audio dealer.

Should your amplifier require service Please consult with the dealer from which it

was purchased, or contact Memphis Car Audio Customer Service: 800-467-2400 or

[email protected]. Do not attempt to return your amplifier directly to

us without first calling for a Return Authorization Number. Units received without an

accompanying Return Authorization Number will be processed more slowly.

Additionally, you must include a copy of your purchase receipt from an authorized dealer

for consideration of in-warranty service; otherwise repair charges will apply. Units

received without a receipt will be held for 30 days, allowing us time to contact you and

obtain a copy of the receipt. After 30 days, all units will be returned to you, un-repaired.
