  • Page 2: Important Safety Instructions

    Thank you for purchasing this Rockville KRYPTON Series 2-Ohm Stable Class AB Marine amplifier. Over the years, the technology used to create audio amplifiers has grown by leaps and bounds. Our competition is satisfied with just continuing to build the same units year after year without thought for improvement, but not Rockville. We consider it our mission to use our expertise in developing the latest technologies and to bring you the absolute best sounding amplifiers on the market and of course at a reasonable price.

  • Page 3: Installation Basics

    Before you begin your installation, disconnect the NEGATIVE(-) terminal from your vessel’s house battery. This safety precaution will avoid possible short circuits while wiring your amplifier. Rockville amplifiers operate on 12-volt negative ground systems only. It is recommended that you lay out your sound system design on paper first. This will help you during the installation so that you have a wiring flow chart and do not miss-wire any of your components.
  • Page 4 Wiring 1. Make sure to disconnect the NEGATIVE (-) terminal from your vessel’s house battery. 2. Attach an 4-gauge or heavier wire to the amplifier screw terminal marked GND. Connect the other end to the house battery’s NEGATIVE (-) terminal. The connection should be as close to the amp as possible (20 feet or less).

  • Page 6: Adjusting The System

    Using the Electronic Crossovers KRYPTON Series Class AB Marine amplifiers feature fully adjustable 12dB per octave low-pass (band pass), high-pass, and full-range electronic crossovers. For Low-Pass systems, set the CROSSOVER MODE switches to LPF (BPF). Now the control marked LPF will control the low-pass frequencies from 40Hz – 4KHz (F1, F2) and 50Hz – 250Hz (T2).
  • Page 7 Sealed Enclosures Sealed boxes are tuned by enclosure volume: larger enclosures tune lower; smaller enclosures tune higher. Subsonic frequencies can cause damage to your woofer as they cause it to play below the enclosure’s tuning, forcing it to the limits of its excursion and making it expend a lot of energy. To avoid damage to your woofer, set the Subsonic HPF to 25Hz – 35Hz. Ported Enclosures The enclosure’s port should be tuned to a certain frequency so that the enclosure is capable of playing all frequencies above that tuning.

  • Page 8: Input Configurations

    Input Configurations 2-Channel Input If your head unit has a single pair of RCA jacks, feed their output to the amplifier’s Channel 1 and 2 input jacks. Set the INPUT MODE switch to 2CH. The amplifier’s preamp circuitry will automatically mix all the channels and output will occur on all 4-channels. There will be Left and Right balance and Front to Rear fader. SOURCE INPUT MODE SET TO 2 CHANNEL...
  • Page 9 4-Channel Input If your head unit has two pairs of RCA jacks, feed Front Left and Front Right ouptut to the Channel 1 and 2 input jacks. Feed Rear Left and Rear Right output to the channel 3 and 4 input jacks.

  • Page 10: Output Configurations

    Output Configurations 4-Channel Amp in 4-Channel Mode Install any combination of of component or coaxial speakers independently on channels 1 – 4, being vesseleful not to load any single channel below 2-ohm stereo. For typical 6˝ x 9˝ or 6.5˝ or component or coaxial speaker installs, set the Crossover Mode Switches to Full Range.
  • Page 11 4-Channel Amp in 3-Channel Mode Channels 1 and 2 should be wired to component or coaxial speakers with no lower than 2-ohm load per channel in stereo. Channels 3 and 4 should be bridged as per the diagram wiring the woofer to Channel 3’s positive (+) terminal and Channel 4’s negative ( – ) terminal. Set the Crossover Mode Switches of Channels 1 and 2 to Full Range, while Channels 3 and 4 should be set to LPF.
  • Page 12 Output Configurations (continued) 4-Channel Amp in 2-Channel Bridged Mode Channels 1 and 2 and Channels 3 and 4 should be bridged as per the diagram. Wire one woofer to Channel 1’s positive (+) terminal and Channel 2’s negative ( – ) terminal. Wire one woofer to Channel 3’s positive (+) terminal and Channel 4’s negative ( –...

  • Page 13: Public Address System

    Public Address System These marine amps feature a marine public address system with microphone and talk-over functionality. Simply connect the included microphone to the 3.5mm jack marked MIC and you are ready to go. When the microphone is keyed (a), music will fade to the background. When microphone is unkeyed, music slowly fades back in. Adjust the microphone’s volume using the adjustment knob (b).
  • Page 14 Battery Voltage KRYPTON Series Marine amplifiers feature a convenient LED readout which displays the current voltage input while the amp is in use. These amps will go into protect mode when the voltage goes below 10 volts or above 16 volts.

  • Page 17 SVC Configurations The minimum impedance load for a single Krypton Series Marine amp is 2-ohm stereo and 4-ohm mono bridged. Lower impedance loads will cause overheating and may damage the amp. Do not mix different impedance speakers in series and /or parallel combinations, as unequal power sharing and acoustic outputs will result.

  • Page 19: Troubleshooting

    Troubleshooting PROBLEM CAUSE/SOLUTION 1. Short circuit protection - Caused by the power or ground wire not being fastened tightly. Amp goes into protect mode Disconnect the speakers from the amp. If the amp is still in protect mode, you now know the issue is some- where with the power, ground, or remote wire.
  • Page 20 PROBLEM CAUSE/SOLUTION 1. The external fuse is not properly secured to the power wire or is not making proper contact to the wire. Amp won’t power on Ensure the fuse is properly seated and making contact. 2. Your external fuse (inside the fuse holder) is blown. Replace the fuse. Never replace the supplied external fuse with one of a larger value.
  • Page 21 PROBLEM CAUSE/SOLUTION RCA signal using a multimeter. Power but no sound 4. The next thing to check is the speaker wire that is going from the amp to the speakers. If the amplifier is in bridged mode, then be sure you connected the speaker wire to the proper terminals. 5.
  • Page 22 PROBLEM CAUSE/SOLUTION Amp is clipping 3. If the gain setting is too high, this can cause the amp to clip. The proper way to set your gain is to turn your receiver volume to 75% of the max, and then slowly turn your gain up. The second you hear any slight distortion, turn it down one notch and leave it at that setting.
  • Page 23 PROBLEM CAUSE/SOLUTION 5. Noise can be picked up due to bad RCA cables. Specially the super cheap ones. We recommend doing a Distortion, background noise, test with different RCA cables. Replace the RCA cables if needed. crackling, or hissing in the 6.
  • Page 24 PROBLEM CAUSE/SOLUTION Amp keeps blowing fuses Distribution Block Amp Fuse - If both sides of the main fuse have power, and one side of the distribution block has power, but the other side of that fuse is dead, then you’re either dealing with a shorted power wire or an internal amplifier fault.
  • Page 25 PROBLEM CAUSE/SOLUTION 1. This situation happens when you connect the remote turn-on wire to a constant 12V power wire (often this Amp or powered sub does is a yellow wire) instead of to the remote turn-on wire of your receiver’s wire harness. Pull out your receiver not turn off when you turn off and plug the amplifier’s remote turn-on wire into the proper remote turn-on terminal of your receiver’s wire the vessel...
