thinking about a Phoenix Gold line driver

ok im thinking about getting a Phoenix Gold line driver the specks on it says it will give me like 25 more db's would this be a good thing to buy or not .

haha

no it wont give u anymore db's

what exctaly dose it do im kinda noobe so please help me out

 

[RipDaJacka]

dude, my bet is u'll gain prolly 32-33 db's depending on ur resonant freq.. thats only if ur tuned above 35hz tho

 

[RipDaJacka]

also, how do you misspell PIONEER in your signature, when its clearly spelled out properly in your avatar?

didint real notice my sig till you said some thing ill fix that right quick . any way my tuneing freg is 35 hz in my sub box

 

[king ranch 5,000+ posts]

then u should see around 30db gain

 

[RipDaJacka]

actually, it may add a db or so.. it will boost ur input voltage to your amp.. making your gain setting need to be lower.. and thats always a good thing

its main point is to boost pre out voltage causing u not to have to turn your gain up as high which should let the amp run cooler since the gains arent cranked and should help your electrical

line drivers were originally intended to drive lots of long cables to lots of amplifiers. for a variety of reasons, normal HU outputs may be unsuitable for driving cables of several hundred feet, or connections to over 10 amplifiers. A line driver also contains an internal power supply in most cases, removing output voltage limits.

desired features of line drivers are often the lower output impedance and higher voltage capabilities when compared to a HU's output. These can become important when you have LOTS of amplifiers, or VERY long cable runs. such conditions would be much more common in pro-audio.

Because the input signal merely controls the amplifier, the reasoning of "runs cooler" is flawed. the parts of the amplifier that cause it to get hot are very closely tied to the parts that must handle high currents. the "voltage gain" really takes next to 0 work. From a purely technical standpoint, the line driver might cause an increase of around 5 thousandths of a watt of power dissipation.

reports of SPL gains and improved efficiency are more likely attributed to the re-setting of the gains.

And by "resetting" he means correctly setting.

Unless you have a noise problem that gets worse with a higher gain setting, you will gain absolutely nothing from a line driver.

i guess in this case I technically do. though I'm fairly strongly against calling any method "correct" unless you know the user's goal. The argument for pro's and con's of really any method of setting gains and why it would be universally correct would be a good topic for a seperate thread, as it would be fully off-topic here.

just another thing that can induce noise in your system

... or help reduce it.
