Monoblock MOSFET car Audio Amplifier

Congratulations on your purchase of Amplifier.
It has been designed, engineered, and manufactured to bring you the highest level of performance and quality, and will afford you years of listening pleasure.
Thank you for making your choice for car audio entertainment!

Introduction

• With the RIOT MOSFET amplifier series, we are introducing nine new amplifiers, all designed in the USA. This new series includes three monoblock amps, three 2-channel, and three 4-channel amplifiers.
• All RIOT models feature variable low-pass and high-pass crossovers and variable input gain controls. They also incorporate an input voltage sensitivity selector for added system flexibility.
• For further flexibility in the use of a subwoofer, 0-+18dB Bass Boost control has been included on all amplifiers. You can control the subwoofer level with the remote level control module.
• understands that amplifiers are placed in many different kinds of installations, so we incorporated a very flexible system of controls in these amplifiers to help you integrate the amp into your system regardless of the nature of your input source.

What is included?

When first unpacking your new amplifier, please check that the package contains all of the items below. If something is missing, contact the store where you purchased the amplifier.

• RIOT Amplifier
• Remote subwoofer control
• High input cable with connector
• Four (4) mounting screws

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

Monoblock Amplifiers RI 100M, R1600M, and R2000M

Features

Your new RIOT amplifier features the following:

• Class A-B Topology
• Bridgeable outputs (except RIIOOM, 1600M, and R2000M)
• MOSFET PWM (Pulse Width Modulated) Power Supply
• 2 Ohm stable stereo operation with output power increase
• Thermal and speaker short protection
• Soft turn-on circuit
• Remote turn-on/turn-off circuit
• Variable input gain control
• Variable low pass filter
• Fixed high-pass filter
• Variable O to +18dB Bass Boost
• Nickel-plated RCA low-level and high-level inputs
• LED power and protection indicators
• Black anodized heatsink
• Remote subwoofer level control

About 2 Ohm operation

Your RIOT amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel when using parallel wiring. Doubling the number of woofers produces an acoustic coupling effect. This acoustic coupling effect increases the output by about 3dB for each doubling of the number of woofers. When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2-ohm load. If you lack adequate current, your music reproduction will be distorted

General Precautions

Before installing and using your new *OSS amplifier, please be- nuo.osvs1E’ns come 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 the risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp 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 wire and send the amplifier to your local dealer or service center as soon as possible

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.
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.
   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.

Connecting the amplifier
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 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 8 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 8 gauge (or heavier) cable from this fuse to the amplifier location
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 inline fuse
   • 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 the best results

Don’t misuse the level control
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.

Low-Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance Always use a high-quality RCA cable for best audio performance.
NOTE : Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!

High-Level Input Wiring
The high-level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high-level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.
NOTE : Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!
