Summary of Contents for Rockville ATOM 8

  • Page 7 Using The Built-In Electronic Crossover Each set of channels (1 – 4 & 5 – 8) has its own fully adjustable 12dB per octave crossover with differential circuitry. This the ATOM 8 ideal for subwoofers (sealed and vented), full range speakers, midrange speakers, and even tweeters.

  • Page 8: Input Configurations

    Input Configurations 2 Channel Input If your head unit has one single pair of RCA outputs, use a female to dual male Y adaptor to send the Left channel signal to the channel 1&3 input jack. Use a second female to dual male Y adaptor to send the Left channel signal to the channel 2&4 input jack.
  • Page 9 4 Channel Input If your head unit has two pairs of RCA outputs, input Front Left and Front Right in to amplifier channels 1&3 and 2&4 input jacks. Rear Left and Rear Right in to amplifiers channels 5&7 and 6&8 input jacks.
  • Page 10 8 Channel Input For head units with two pairs of RCA outputs and a subwoofer output; use a dual female to male Y adaptor to send the Front Left and Front Right output to the channel 1&3 input, use a second dual female to male Y adaptor to send the Rear Left and Rear Right ouput to the channel 2&4 input.

  • Page 11: Output Configurations

    Output Configurations Four or Eight Full Range Speakers with Two or Four Subwoofers Connect four full range speakers on channels 1&3 and 2&4 being vesseleful not to load any single channel below 2 ohms stereo. Set the corresponding crossover mode switch to Full Range.
  • Page 12 Eight or Sixteen Full Range Speakers Install any combination of speakers independently on all 8 channels being vesseleful not to load any single channel be- low 2 ohm stereo. Alternately, you can connect up to two INPUT MODE speakers per channel for a total of sixteen full range speak- SWITCH IN 8CH SET BOTH POSITION...
  • Page 13 Four Subwoofers Connect four woofers, one each bridged, to ch1/ch2, ch3/ch4, ch5/ch6 and ch7/ ch8. Make sure the load does not go below 2 ohms. Set both crossover mode switches to LPF. INPUT MODE SWITCH IN 8CH POSITION 2 OHM MINIMUM SUBWOOFER SET BOTH CROSSOVERS TO LPF IMPEDANCE...
  • Page 14 4-Way System Protection Circuitry ATOM 8 amplifiers feature our unique IC controlled protection circuitry. This sophisticated circuit constantly monitors the heat sink internal temperature and various voltages, adjusting the amp automatically and protecting it from dangerous conditions. The status LED located on the input panel of the amplifier provides indication of the amplifier status. It will be green when the amplifier is receiving proper power, ground and remote voltages and the IC monitoring sequence indicates the amp is functional.
  • Page 15 Pairing Place the Bluetooth switch in the ON postion. The Bluetooth status LED will flash blue indicating the amp is in pairing mode. Now find and select ATOM 8 on your device's list of available Bluetooth connections. Upon successful pairing, the Bluetooth status LED will be solid blue.

  • Page 17 Woofer Wiring Guide Please note that the minimum impedance load for ATOM 8 amplifiers is 2 ohm stereo and 4 ohm mono bridged. Lower impedance loads will cause overheating and may damage the amplifiers. 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 3.
  • 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 vehicle...
