SAFE LIMITS OF OPERATION

Polk Audio specifies the recommended amplification range for each of its passive (non-amplified) loudspeakers. Typically that specification will be expressed as a range of power such as 20-200 Watts (per channel). It is important to understand what those numbers mean when choosing a receiver or amplifier for your Polk loudspeakers. The lower number indicates the lowest continuous rated power that will yield acceptable performance in a typical listening environment. The higher number indicates the highest per channel power that should be used with your Polk speakers. That number should not be confused with a “Power Handling” specification and it does not imply that the speaker will safely handle that full amount of power on a long-term basis. We specify a wide range of power ratings because not all electronics manufacturers use the same method for rating power. In fact, high quality lowerrated amplifiers sound better and play louder than low quality units with higher power rating. Automobile horsepower is good analogy. Your car probably has far more horsepower than it needs for your daily commute and is likely capable of going well over 120 MPH (190KM/hr). Having that extra power is good for on-ramp acceleration and danger avoidance (like getting away from brain-eating zombies) but that doesn’t mean that it is advisable to operate your car on North American highways at full power and maximum speed for an extended period of time. Just ask your local state trooper if you are in doubt. Similarly, we recommend using amplifiers and receivers with rated power above the Power Handling limits of our speakers because having extra power available for short terms peaks is conducive to better sound quality, maximum dynamic range and effortless high volume output. But we strongly urge you not to use the full power of your amp or receiver for daily listening. Loudspeakers can be damaged when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce. Operation at this level can result in very high levels of audible distortion originating in the amplifier, which can add a harsh, gritty sound to your listening material. If you hear distortion—turn the volume down or risk damaging your speakers. You can damage just about any speaker, regardless of power rating, if you drive an amplifier to or beyond the point of distortion. INSTALLATION GUIDELINES

1. Please read this owner’s manual carefully before

installing this amplifier.

2. Disconnect the battery ground terminal prior

to making any electrical connections.

3. Check for any hazards or obstructions such as gas

tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier.

4. Pick a mounting location that will provide adequate

access and ventilation and protect the amplifier from heat, moisture, and dirt.

5. To securely mount your amplifier you must first remove

the top cover assembly. Unscrew the four (4) top cover assembly retaining screws.

6. Avoid sharp metal areas when routing cables to the

amplifier, and run RCA cables away from the power cables and other potentially noisy car harnesses.

7. The amplifier should be grounded with a short, heavy

gauge wire connected directly to the car at a bare metal surface, preferably scraped body sheet metal. Do not use factory ground locations, seat bolts, or brackets that are spot welded.

8. Always fuse your power connection within 8 to 10 inches

of the battery terminal. Use a fuse or circuit breaker rated slightly more than the on-board fuse(s) of the amplifier(s). The gauge of power wire used should take into account the total current draw of the system, and the length of wire used. IASCA and other auto sound competition organizations have charts available for this; you can also find a chart in the MECP study guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification page. Always use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle, and if necessary, upgrade it by adding an additional ground wire that is the same gauge as the amplifier’s power wire. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires.

9. This amplifier is designed to drive a speaker load that

measures from 1 to 4 Ohms. Keep in mind that heat is the long-term enemy of automotive electronics and the lower your speaker load, the more heat is generated. For low-impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable.

WWW.POLKAUDIO.COM/AMPS

10. Battery and ground connections to the vehicle should

be made with crimped ring terminals of the appropriate size (surface area is what counts;) soldering the terminals after crimping is also recommended.

11. Due to the high-frequency MOSFET switching power

supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted.) Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system.

9. Phase Switch—0° or 180° selectable for switching

the phase output to the woofer.

10. LED/FAN Connector—Allows connection of an

optional cooling fan for the amplifier.

11. Status LED—Will illuminate GREEN to indicate the

amplifier is on and operating normally, and will be illuminated RED if the amplifier shuts down due to short circuit, DC offset, or overheating detected by onboard protection circuitry.

REAR PANEL CONNECTIONS

1. Fuses—These fuses protect the amplifier against

internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source. The PA400.1 uses 2-25A fuses, the PA600.1 uses 2-30A fuses and the PA1200.1 uses 3-40A fuses.

2. (+) 12 Volt Power—Connect this terminal through a

FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery.

WARNING: Always protect this power wire by installing

a fuse or circuit breaker of the appropriate size within 12 inches of the battery terminal connection. FIGURE 1b— REMOTE Remote—Controls the subwoofer amplifier gain, from a remote location for ease of adjustment during listening.

Warning: DO NOT connect a level control knob from other

manufacturers to the Remote Sub Level Control of any Polk Audio amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged.

FRONT PANEL CONNECTIONS/CONTROLS

1. RCA Input Jacks—Accepts line level outputs from

head units or signal processors at voltages between 150mV and 7.5 volts.

2. RCA Line Output Jacks—These pass through

RCA jacks can be used to send the input signal to a second amplifier.

3. Slave/Master Switch—Controls whether the

amplifier is a slave or master when connected in combined amplifier configurations. (Refer to the Combined Amplifiers section of this guide.)

4. Gain Control—Controls the amplifier’s sensitivity

and is used to match the input level of the amplifier to the output level of the signal source.

PA 12V AMPLIFIERS

3. Remote Turn On—This terminal turns on the amplifier

when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source.

4. Ground—Connect this terminal directly to the sheet

metal chassis of the vehicle, using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points.

5. Speaker Terminals—Connect subwoofers to these

terminals. (Refer to the Speaker Wiring Diagrams section of this guide.) FIGURE 3—AMPLIFIER CONNECTIONS—REAR (PA400.1/PA600.1/PA1200.1) Phone Line Cord Remote Volume Module

5. Subsonic Switch—The subsonic filter attenuates

frequencies below 30Hz by 24dB per octave.

6. Bass EQ Switch—Adds 8dB of bass boost to the

subwoofer when selected.

7. Remote—Controls the subwoofer amplifier gain,

from a remote location for ease of adjustment during listening.

Warning: DO NOT connect a level control knob from

other manufacturers to the Remote Sub Level Control of any Polk Audio amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged.

• Setting the SLAVE/MASTER switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifier’s slave or master designation. NOTE: One master amplifier can control up to three SLAVE amplifiers in this combination. Multiple identical MASTER/ SLAVE combinations can be added to any given system. NOTE: The dual (+) and (-) sub-out terminals of the PA400.1, PA600.1 and PA1200.1 are paralleled internally, and the combined load impedance should be taken into consideration when connecting multiple subwoofers. COMBINING AMPLIFIERS

EXTERNAL SYNCED BRIDGED

The Polk 600.1 and 1200.1 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations. In this MASTER/SLAVE combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common subwoofer loads while being synced together via an out-ofphase audio pre-amp signal from the master amplifier. In this subwoofer wiring configuration the master amplifier sends the positive signal to the subwoofer while the slave amplifier sends the negative signal, making an externally bridged speaker connection. (Refer to External Synced Bridged section of this guide for amplifier and speaker connection diagrams.)

WARNING: DO NOT attempt to combine amplifiers of

different power ratings. These amplifier combinations work correctly only if the MASTER and SLAVE amplifiers are identical models.

PARALLEL SYNCED GAIN

In this MASTER/SLAVE combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive their own separate subwoofer(s) while being synced together via an in-phase audio pre-amp signal from the master amplifier. Wiring connections to the amplifier subwoofer outputs in this combination should be standard in-phase configurations, creating a parallel speaker connection. (Refer to Parallel Synced Gain section of this guide for amplifier and speaker connection diagrams.)

3. Phase Switch—Set the phase switches of all synced

amps to the same position (all at 0° or all at 180°).

4. To Achieve Safe, Optimal Performance—The LPF,

Bass EQ, and Subsonic Filter controls on all synced amps must be set to the same position.

5. Signal Connection—Connect an RCA cable between

the OUT RCA jack of the master amplifier and the SLAVE IN RCA jack of the slave amplifier as shown in the Figure 5.

6. Subwoofer Speaker Connection—In this amplifier

combination, each amplifier must drive its own separate subwoofer(s). Connect the speaker terminals of each amplifier to any combination of one or more subwoofers that results in nominal impedance between 1 and 4 ohms. Make sure that each amplifier sees the same speaker impedance.

WARNING: The amplifier’s gain control is bypassed completely in SLAVE mode. DO NOT move the MASTER/SLAVE

switch to SLAVE position when the amplifier is connected and playing. DO NOT connect any signal source to the amplifier in SLAVE mode that exceeds 200mV. NOTE: Amplifiers in this combination can only be connected in matched pairs. Multiple matched pairs may be added to drive separate subwoofer loads in a given system. COMBINED AMPLIFIERS

GAIN AND FILTER SETTINGS

NOTE: You MUST set the Subsonic, EQ, and other filter settings on the masteramplifier to the same positions to achieve safe, optimal results. Adjustment guidelines are discussed in the Crossover and Gain Adjustment section of this guide. NOTE: One master amplifier can control up to three slave amplifiers in this combination. Multiple identical MASTER/ SLAVE combinations can be added to any given system. SLAVE AMPLIFIER

and the INPUT RCA jack of the Slave amplifier as shown in Figure 6.

6. Subwoofer Speaker Connection—In this amplifier

combination, the Subwoofer speaker terminals of both amplifiers drive common subwoofer(s). Use the following speaker connection diagram when connecting the subwoofers to the amplifiers. Connect the amplifiers speaker terminals to any combination of one or more subwoofers that results in a nominal impedance between 2 and 4 Ohms. DO NOT connect loads of less than 2 Ohms when connecting to amplifiers in the External Synced Bridged combination. SLAVE AMPLIFIER

WARNING: Two wires of 12AWG minimum must be

connected between the negative sub out terminals of the MASTER and SLAVE amplifiers.

WARNING: The amplifier’s gain control is bypassed completely in SLAVE mode. DO NOT move the MASTER/SLAVE

switch to SLAVE position when the amplifier is connected and playing. DO NOT connect any signal source to the amplifier in SLAVE mode that exceeds 200mV. S L AV E

WWW.POLKAUDIO.COM/AMPS

MULTIPLE AMPLIFIER COMBINATIONS

The PA400.1, PA600.1, and PA1200.1 subwoofer amplifiers can also be used in Multiples of the MASTER/SLAVE combinations allowing for unlimited expansion to a system’s subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results.

• Audio Signal—Divide the head unit or processor audio signal to the master amplifiers by using RCA Y adapters. Be sure to divide them an even number of times to ensure the input level at each master amplifier is matched.
• Amplifier Configuration—Set up each MASTER/ SLAVE amplifier combination as described for the combination type being used. (Refer to the Parallel Synced Gain or the External Synced Bridged section of this guide for amplifier and speaker connection descriptions.) CROSSOVER SETTINGS

AND GAIN ADJUSTMENT

Your Polk Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier.

• Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times. The crossover point is adjustable to allow more precise system operation.
• Try and keep the setting low enough to prevent image smearing (you should not be able to hear male voices from the subwoofer) but not so low as to create a gap between the subwoofer and the mid-bass/midrange speakers. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer.

• The gain adjustment allows you to set proper signal match for clean, quiet amplifier operation. Start by playing some music you are familiar with. With the gain adjustment on the amplifier in the middle of its rotation, bring up the volume on your head unit to the 3/4 volume setting or until you start to hear distortion or clipping. If you hear distortion before you reach the 3/4 volume setting of your head unit, reduce the gain setting on the amplifier and start to raise the head unit volume again. When you can listen to the music at or slightly above 3/4 on your head unit without audible distortion, slowly raise the gain of the amplifier until distortion is heard, then back off the gain until the distortion is not audible. This setting will allow you to reach full output with all but the quietest of source material, while avoiding excessive noise in the system. CEA SPECIFICATIONS

• For systems using the Remote Sub Level Adjustment, increase the subwoofer gain on the amplifier by 25% and set the Remote Sub Level knob to the center position after making all system gain and filter adjustments. This will give the Remote Sub Level Control a wider range of adjustment to the subwoofer output.
• You should take into consideration the effect that gain adjustment has on system frequency response and staging. Again, plan on spending some time with music that you know getting the gain and crossover settings the way you like. Test discs and analyzers may help with this process, but in the end it’s your ears that count, listen to the music!
