Line Driver Specifications

Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
10 volts
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
96 dB

I bought this to amplify the signal for my aux cable for my bmws dsp system. This product works wonders! Followed their recommended levels for sound adjustment and its left me more than pleased. I'll be recommending this to anyone who needs to raise the signal from your media player/phone!

March 17, 2012

It boosts the signal from my iPod that I have hooked directly to the amp. I am running a Vibe Litebox2 amp, Polk MM691 speakers and the PAC LD-10 in an icechest radio. I hooked the ipod directly to the amp with out the line driver and it was ok. I then hooked up the line driver and only had to turn it up 1/8 of the way. It made it sound like a dream. If you are going to hook an MP3 player to the amp with out a headunit I would suggest you get a linedriver. This one does not have any mounting screws or holes to use your own. I ended up using velcro to attach it to the inside of my cooler. It is a little flimsy but once you set it and find a way to mount it you shouldn't worry about that.

I purchased 2-15s boss phantoms 2500 watt subwoofers and a 5000 watt lanzar vibe amp...it sounded great...but I wanted more..I wanted to more 15s but then I looked this product up. if you want bigger better louder sound without upgrading or buying more subs or amp...buy this line driver...it did the trick for me...and I have plenty of power left in my system...my gains are low and I have plenty bass to go around ....I love this really...I would definitely recommend this to anyone with a sound system....it will blow your mind...this item will turn a small system into a huge system...for 2-15s...my system sounds like 4-18s..in a trunk...no hairs tricks..but whole car shakes...neighbors all around complains...and if your standing by the car..your clothes vibrate...in the car....bass takes your breath away....so I have no complaints.....I do suggest you get some tweeters and more highs and midrange...I absolutely love this product.

Great Line Driver/Signal Booster for Portables

September 9, 2013

I would recommend this product if you need to boost levels before going into any input. It is especially good for boosting output of portable devices before the aux input. In my case I used it to boost output from a Bluetooth receiver into the aux input of a Land Rover LR3, a vehicle which is notorious for low signal levels on the aux port. Now the output matches the other sources (CD, Radio, Sat, Nav).

I have this with two kicker zx400.1 and it gives the voltage to keep the amps from running too hard off the low voltage my radio puts out. I like that you can fine tune your system off of this, its great. No pops from the amps how I have it hooked up to a constant 12v source. As always sonic has everything car audio I need, THANKS SONIC!!

Turn-off thump

June 22, 2012

I used this preamp to boost the line level to my sub amp. It worked well and sounded good, but made the subs "thump" on turn off. This could probably have been solved by running the preamp power from constant 12V instead of from the remote (it takes very little current) or delaying the turn off, but it annoyed me so much that I just removed it and found another solution.

PAC LD-10 - Worth Ever Penny!

July 31, 2015

I utilize this in a speaker cooler in between my BT (Fusion MS-BT100) and my amplifier (Polk PA D2000.2).

When I tune the amplifier using a multi-meter I can obtain the correct output AC voltage from my amp with this line out driver. This pre-stage amplification allows the input voltage to match what my amp needs to output the correct AC voltage for peek gain performance.

The only down sight I see is that the two input signals are adjusted independently and you have to eyeball that they are at the same level when adjusting with a screw driver.

No matter if you are connecting through a BT dongle to amp or directly from your iPhone to amp, this PAC LD-10 should be installed to allow your amp to reach its full potential.

I would HIGHLY recommend this line out driver when building a speaker cooler! Worth the $21!

Shielding

October 5, 2015

The Output leads should be shielded to avoid interference. I tried everything to get the hiss out and the tones from the cars computer interaction with the car. I grounded it to dead and cut the noise down to half. I already bought a new one and this time I'm wrapping the output leads in aluminum foil and make sure they touch the ends for a ground. My phone was the worst. Even a foot away it was receiving the electronic tones of computing.

Preamp voltage BOOST!

September 6, 2016

Head unit not putting out the preamp voltage as advertised with a clean signal? Look no further. The PAC LD-10 is the answer. Very easy to power. Very easy to set! At the cleanest volume setting, i was only seeing 2 volts max. After installing the LD-10, i have over 4 volts and allowing my amp to operate at its full potential while not having to work so hard!

Looked long and hard to find this type of item for my truck's new head unit. Mathew @ Sonic was helpful in verifying that this would do what I needed done, and the price is right for the application. And the free shipping was just a plus that sealed the deal. Thanks, y'all!

need to boost the output voltage of my subwoofer outputs on my head unit

Hi, can I drive headphones with the output of this unit?
Frank H on Jun 17, 2015
Best Answer: Hi,

i didnt try to drive headphone with the output of this. this product designed to boost the signal to an amplifier. If you drive your headphones on RCA line today, and you need some boost, Maybe this product will help you... but that a big maybe because i did not try it myself.

I have a Kenwood head unit with a RCA line out for a subwoofer. I'd like to use this output to drive a small sub amp that requires speaker level input. Would this unit fit this application? A conventional inexpensive 'line driver' does the reverse of what I'd like to do, and the typical unit that could accomplish this feat would cost more than I've spent on the entire installation.
JerryASV on May 7, 2016
Best Answer: Normally a amp that uses speaker level (high level inputs) uses the speaker wires off the radio to give it the input thus you would not need this part. However if you are trying to use it because the radio has subwoofer contols and you are trying to use that feature this product would work but as a installer for over 20 years it would not be the best option but not knowing what amp kinda leaves me in the dark. I would purchase a new amplifier but I dont know what your system build is.

Can I use this unit to boost streaming audio from the 'Net? I use wireless headphones from the computer in the house out to my shop. I though that this might work if I installed it before the wireless transmitter to boost its output. Any suggestions?
Dave L on Dec 3, 2014
Best Answer: It could boost audio volume, but it would be very impractical for use on that rig. If your audio is quiet you should check the volumes on your headset, it's adapter, Windows, and the audio player on the website.

if you are worried about distance. Unfortunately this device only boosts the volume of audio and cannot increase your wireless signal distance. :/
