Introduction
With the Planet Audio RXD series, we are introducing four new CLASS D amplifiers, all designed in the USA.
All four RXD models feature variable low pass and subsonic filters and a variable input gain control. They also incorporate a phase selector switch to help compensate for time delays in subwoofer applications.
For further flexibility in the use of a subwoofer, a variable 0-+18dB Bass Boost control has been included.You can control the subwoofer level with the included MOBB-17 remote level control module.
Planet Audio understands that amplifiers are placed in many different kinds of installations, so we have also included an input sensitivity control to help you integrate the amp into your system regardless of the nature of your input source.
A special feature on this Class D amp is DataLink circuitry, which allows you to “strap” together two identical RXD models for an astounding total maximum output power.
Features
Your new RX amplifier features the following:
• Class D operation
• MOSFET PWM (Pulse Width Modulated) Power Supply
• One Ohm stable mono operation
• Thermal, overload and speaker short protection
• Soft turn-on circuit
• Remote turn-on/turn-off circuit
• Variable input gain control
• Input voltage sensitivity selector
• Variable subsonic filter: 15-40 Hz, 24/dB/octave
• Variable low pass filter: 50-150 Hz, 24/dB/octave
• Variable 0-+18dB Bass Boost
• 0/180º Phase Shift selector
• Nickel-plated RCA low level inputs
• Nickel-plated speaker and power terminals
• LED power and protection indicators
• Heavy duty aluminum heatsink
• Remote subwoofer level control

Installation precautions
Before you drill or cut any holes, investigate your car's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring.
Never operate the amplifier when it is unmounted. Attach all audio system components securely to prevent damage, especially in an accident.
Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer's warranty.
Mounting the amplifier
1. Find a suitable location in the vehicle in which to mount the amplifier.
2. Make sure there is sufficient air circulation around the intended mounting location.
General precautions
Before installing and using your new Planet Audio amplifier, please be­come familiar with all the information contained in this manual.
Please keep this manual in a safe place for future reference.
• Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result in electric shock. Refer any repairs to a qualified service technician.
• To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible.
• If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power cord and send the amplifier to your local dealer or service center as soon as possible .
What is included?
When first unpacking your new amplifier, please check first that the package contains all of the items below. If something is missing, contact the store where you purchased the amplifier.
• Class D amplifier
• Remote subwoofer level control
• Remote subwoofer control cable
• DataLink cable (for strapping two identical RX Class D amps together)
• Four (4) mounting screws
RX Class D Amplifier User’s Manual - page 4
3. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.
4. Drill pilot holes in the mounting surface for the mounting screws. Place the amplifier in position, and attach the amplifier to the mounting surface securely using screws.
Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. Be sure you understand all the connections before you proceed.
1. Connect the amplifier’s power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39" (100 cm) in length. Use 4 gauge (or heavier) wire.
2. Connect the remote terminal to the remote output of the head unit using 16 gauge (or heavier) wire.
3. Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 4 gauge (or heavier) cable from this fuse to the amplifier location.
The purpose of placing a fuse in this location is to protect your vehicle’s battery in the event that this wire accidentally touches the chassis ground on its run to the amplifier.
Connecting the amplifier
4. Check that the fuse holder is empty. Then connect the fuse holder to the "BATT+" connection on the amplifier.
5. If multiple amplifiers are being used in your system, either:
• Run a separate pair of cables from the battery and a chassis ground point to each amplifier. Each (+) cable must have its own inline fuse.
-or-
• Run a #4 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location. Then run separate cables from the amplifier to this distribution block and to independent chassis ground points.
6. Connect all line inputs and outputs (if used) using high-quality cables. Connect all speakers, following the diagrams in this manual. Be sure to observe proper polarity to avoid audio phase problems.
7. Insert fuse(s) into the battery fuse holder(s).
8. Recheck all connections before powering up the amplifier.
9. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.
10. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier’s input level control(s) to just below the level of distortion.
11. Further fine tuning of the various controls may be necessary to obtain best results.

Important installation considerations for using this amplifier.
SHOCK HAZARD! Do not open the case of this product. There are dangerous
voltages present within the unit. There are no user-serviceable parts within the unit.
The fuse ratings for three of the amps is shown on the Specifications page at the back of this manual (The RXD2400 requires an outboard fuse of your choosing). Although sufficient for normal working conditions, overloading the amp may result in blown fuses. Please try to avoid overloading the amp in this manner.
Your RX Class D amplifier is designed to run with a mini­mum load of 1 Ohm.
Operating the amplifier with a speaker impedance load be­low 1 Ohm may result in poor sound quality and damage to the amplifier circuitry. Such damage is not covered under the warranty for this product.
When making electrical connections to the amplifier, please observe the following:
• Always use 4GA or heavier wire for power and ground connections.
• Wire the amplifier directly to the car battery. Make sure there is circuit protection (such as a fuse) on the positive power lead within 18” of the battery.
• When making a ground connection, always use the shortest possible wire to a good chassis ground point.
• Wire the remote turn-on connection to the remote turn-on lead of your EQ or head unit. In some cases, this may be the power antenna lead of the head unit.
• Fuses protect BOTH the amplifier and the electrical system of your vehicle from faulty conditions. If you must replace a fuse on the amplifier, you must use a fuse of exactly the same type and rating. A different type of fuse or rating may result in damage or cause a fire.
Tips for making your system as safe as possible
Do not mistake the input level control for a volume control! It is designed ONLY to match the output level of your audio source to the input level of your amplifier.
Do not adjust this input level to maximum unless your input level requires it.
Ignoring these instructions will result in an input overload to the amplifier, and excessive audio distortion. It can also cause the protection circuit to engage.
Don't misuse the level control!
