About & Features: 


Bluave is know for our passion for the ultimate sound quality and performance in the  marine audio industry.  In the pursuit to reach another ground breaking  level we have designed in the BLU series amplifiers. The BLU series  amplifiers provide smooth accuracy and incredible power.  They are the  Soulmate  match for the BLUAVE marine speakers & subwoofers  providing true reproduction of musical perfection.  At Bluave we also  know that the marine and off-road environment can be extremely brutal  here are some of the amazing features of the BLU series amplifiers. 

  • SOUND  QUALITY:  We use the highest quality and latest technologies in D class  mosfet outputs producing extreme clean & powerful signal even at  high volume.  You will experience precise sound quality even with the  gains set at 75-95%  Self limiting outputs this feature senses  distortion at high volumes and limits the output rails reducing  distortion.  If distortion is detected the output slightly back down  protecting your loudspeaker and retains smooth clarity. 


  • OUTPUT  POWER : by using a regulated power supply. This allows our amplifier to  reach its full rated output at a wide range of the boat/UTVs battery  voltage (11V-14.5V)


  • RCA INPUTS & RCA OUTPUTS


With  today’s technology your source for music may vary from a Bluetooth  module, marine grade head-unit or even a DSP.  Our RCA input have a wide  range of input sensitivity to accommodate that flexibility with this x1 to  x10 input range it allows the ability of the music source to range from a  weaker output to a stronger output with out the need for line drivers  to achieve the same volume results.   For example with a stronger source  from a DSP you reach full volume with minimal gain and with a weaker  module or headunit signal you can achieve running the gains at full or  near full with out sending a clip signal to your drivers. Our crossover  section also gives you the flexibility to only use one set of RCA on  input 1/2 and run the entire 4 channels of the 800.4 or 8 channels of the limited 1600.8 Our built in RCA  outputs are simple and functional the RCA outputs are simply paralleled  with the  RCA input 1/2 allowing you to just a FULL range signal to  additional amplifiers 

  • EFFICIENCY  & POWER CONSUMPTION: We know battery voltage can always be a  challenge in a boat or UTV. To fight this constant battle with voltage  we designed our amps with the latest technology in D-class  MOSFET  outputs & power supplies. BLU series amps are THE most Efficient big  power amps in the business.  


  • ENVIRONMENT:   The BLU series amps are designed with a true Marine build, the BLU  series circuit boards are sealed in military spec conformal coating. The  amp housing, logo, harness and both sides are backed with a water tight  gasket at every seem.  To produce big power & run all day even in  extreme temperatures our amps are designed and equipped with 2 sets of  heat sinks, this allows the certified BLUAVE dealer/installer to mount  the amp in any position and helps the keep the amp well with in  operating temperatures.

B2800.4 Tuning

 Bluave Marine Audio tuning suggestions
 

( NOTE: confirm ALL speakers and subs are in phase a single speaker out  of phase WILL drastically effect the performance of the sound system )
 

*Step 1
Read page#? SPEAKER OUTPUT & CROSSOVER SELECTION  ( understand the amps functions before beginning )
 

* Step 2
Always tune the system with the same music source the client uses.
Confirm the consumers primary source for music. ( example: iPhone or  android , iTunes , iTunes downloaded , Spotify, pandora, Sirrus/XM ,  etc...  Each source can have a different level of output volume   This  is very important to confirm to be able achieve full volume.    For  example if you tune the clients system for ITunes and they primarily use  Pandora they may not be able to reach full volume potential.   
 

*Step 3
Confirm your vessels batteries are FULLY charged and in good operating  condition.  Tuning a sound system with low or bad batteries will NOT  work and is bad on your electronic components. 
 

*Step 4
On your marine audio headunit check your balance “lefts & rights”
 

*Step 5
Confirm ALL ZONES “fade” once confirmed left and rights are correct move on to step 5
 

*Step 6
Confirm the Marine Audio head-unit  is set to flat
Bass 0, Mid 0, Treble 0,  & if the headunit has a pre set DSP we  suggest it is turned off before tuning begins.    The general tune  should be done with the amplifier crossover sections. Once the tune is  completed you can make SMALL adjustments with the headunit ONLY if  needed. 
 

*Step 7
Pick a “preferably” downloaded song with a great range of lows,mids,highs
We suggest that the same song is used until the complete tune.  Then  once your satisfied with the tune try several other songs and make small  fine adjustments if needed. 
 

*Step 8
Ok now that steps 1-7 are confirmed
If the system has a subwoofer turn the subwoofer off by the headunit sub zone or unplug the sub or RCA if applicable
 

*Step 9
With the gain the entire way down on the amp channels.  Pre-set the frequency’s and setting as suggested in page #?
 

*Step 10
Designate a “MAX” volume headunit.  We suggest picking a volume about  85-95% of the highest volume number on the headunit for example. If the  max volume is 50 you would set your designated max volume at 45.  Keep  the head unit at 45 and the song on repeat Until the complete tune  process is complete.
 

*Step 11
Tune one set of channels/speakers at a time.   We suggest this because  every speaker location may perform / respond differently.  So one set of  channels/speakers may require more or less gain OR more or less  frequency. 
 

* Step 12
With the frequency at the suggested position Start working the gain up  slowly till you reach a high & clear volume.   If or once you hear  distortion slowly back the gain down till the distortion is audibly gone  and then down another 5% ( low distortion will accrue before you can  hear it by ear ).  If you have it available you can use a distortion  detector or scope to set your max gain. 
 

*Step 13 
Now that the gain is set you can finesse the frequency by SMALL  movements.  Try lowering the frequency & try raising the frequency  to find the best performance.   Once this is completed you maybe able to  slightly raise your gain to achieve max performance.  ( remember the  suggested frequency setting are for the majority, however some vessels  may perform completely different and require setting outside of the  suggested tune )
 

*Step 14
 now that channel/speaker 1/2 are fine tuned.  Repeat steps 8-12 for all  applicable channels/speakers/subs ( remember to re-activate your  subwoofer  once all coaxials are tuned ) 
 

*Step 15 test a variety of songs and sources to confirm your system is well balanced and performing at max potential.
